Characteristics and challenges of companion animal rescue organisations in New Zealand.

AIMS: To describe the characteristics of companion animal rescue organisations (CARO) in New Zealand; to describe current capacity, resource limitations and challenges of CARO with a particular focus on cats and dogs; and to explore support for creating a national database of CARO in New Zealand. METHODS: A cross-sectional survey was administered to CARO in New Zealand in May 2022. The survey asked about organisational characteristics, types and numbers of animals cared for, services provided, policies, staffing, funding sources, challenges, and attitudes towards a national database for rescue organisations. Descriptive statistics were provided for all quantitative study variables and free-text comments were analysed for common themes. RESULTS: The survey was completed by 106/208 (51%) known CARO distributed across the country. These CARO provided services to an estimated 59,874 homeless animals annually with 86/106 (81%) providing services to cats and/or dogs. Primary services provided by CARO who cared for cats or dogs included rehoming (72/86; 84%) and housing (70/86; 81%) animals. Intake was managed through a combination of strategies. Donations (72/86; 82%) were the main funding source. The 62 registered charities were more likely to report being funded by grants than the 23 non-charities (39/62 (63%) vs. 1/23 (4%); p < 0.001), and non-charities were more likely to self-fund (18/23 (78%) vs. 20/62 (32%); p < 0.001). Nearly half of the CARO that provided workforce information (35/72; 49%) had a workforce of 10 or fewer including volunteers. A total of 5,699 people worked for 86 CARO that care for cats or dogs of whom 4,847 (85%) were part-time volunteers. Of the 72 cat and dog CARO who provided workforce information, 57/72 (79%) relied solely on volunteers.The majority of all 106 CARO respondents (78/106; 73%) indicated they were likely to register on a national database of CARO, subject to addressing concerns about time required and information security.CARO respondents described challenges of insufficient funding, access to veterinary services, and a shortage of volunteers and foster homes, with additional concerns including a lack of public awareness, supportive legislation, and resources. Financial support (90/106; 85%) and policy change (76/106; 72%) were preferred support options. CONCLUSIONS: This study highlights the significant role played by CARO in New Zealand and the challenges they face, emphasising the need for financial support, legislation, and initiatives extending beyond the rescue sector to reduce the number of animals being surrendered. The findings also suggest a willingness among CARO to participate in a national database.

Euthanasia of dogs and cats by veterinarians in New Zealand: protocols, procedures and experiences.

AIMS: To collect data on protocols used by New Zealand veterinarians to perform euthanasia of dogs and cats, and to explore opinions towards the training they received in euthanasia during veterinary school. METHODS: A cross-sectional survey was administered to all veterinarians registered with the Veterinary Council of New Zealand. The survey asked respondents about their practices' policies for euthanasia; protocols for performing euthanasia of dogs and cats; opinions towards euthanasia training received in veterinary school; and subsequent experiences with euthanasia in practice. Descriptive statistics were provided for all quantitative study variables and thematic analysis was performed on the free-text comments. RESULTS: The survey was completed by 361/1,448 (24.9%) veterinarians in companion or mixed animal practice. The mean numbers of dogs and cats euthanised each month were 7.2 (median 5; min 0; max 60) and 7.9 (median 5; min 0; max 60), respectively. Fewer than half of respondents reported that their clinic had a standard protocol for euthanising dogs (147/361; 40.7%) or cats (157/361; 43.5%). For euthanasia of dogs, 119/361 (32.9%) always used sedation while 71/361 (19.7%) indicated that they would not use sedation. For euthanasia of cats, 170/361 (47.1%) always used sedation while 53/361 (14.7%) indicated that they would not use sedation. Placement of IV catheters, methods for patient restraint, preferences towards the presence of owners during euthanasia, services provided with euthanasia, and discussions with owners were also highly variable and handled case-by-case depending on the client, patient, and clinical scenario. When asked about the euthanasia training received at veterinary school, it was generally ranked as below satisfactory, with approximately one-third of respondents indicating that they received no training in dealing with emotional clients (113/361; 31.3%), sedation protocols for euthanasia (107/361; 29.6%), or managing compassion fatigue (132/361; 36.6%). Most respondents (268/361; 74.2%) received no formal training in euthanasia after graduation and learned from experience or discussions with colleagues. Providing animals and owners with a good experience during the euthanasia process was highlighted as important for managing compassion fatigue. CONCLUSIONS: Euthanasia is a common procedure in companion animal practice and there is considerable variation in how veterinarians approach both the technical and non-technical elements. Training provided during veterinary school was generally considered below satisfactory, particularly regarding managing compassion fatigue and clients' emotional needs. CLINICAL RELEVANCE: Providing veterinarians with additional training on adapting their euthanasia protocols to different clinical scenarios may improve the experience for patients, owners and veterinary staff.

Practices and opinions of New Zealand sheep farmers towards pain management in lambs during castration and/or tail docking.

AIMS: To collect baseline data from New Zealand sheep farmers on techniques for docking and castrating lambs, their perceptions of the level of pain lambs experience following these procedures, and their opinions about the use of pain relief. METHODS: From a voluntary cross-sectional survey of New Zealand sheep farmers, descriptive statistics were provided for quantitative study variables. Thematic analysis was performed on the free-text comments. Univariable logistic regression was used to assess factors associated with farmers indicating they would consider using a device allowing administration of pain relief simultaneously with castration and tail docking. RESULTS: There were 432 survey responses containing sufficiently complete data for analysis. Of the 340 individuals (77.5%) always or sometimes performing castration of ram lambs, 242 (72.2%) used rubber rings for complete castration, 23 (6.9%) used the short scrotum method for cryptorchid castration, and 75 (22.4%) used a combination of both methods. Of the 423 individuals (97.9%) who indicated that they always or sometimes performed tail docking, 245 (57.9%) used a hot iron only, 148 (35.0%) used a rubber ring only, 26 (5.8%) used both methods, 3 (0.7%) used a surgical knife, and 1 (0.2%) provided no response. Less than 2% of respondents always or sometimes used pain relief for these procedures. Of the 432 respondents, 139 (32.2%) and 180 (41.7%) strongly agreed that castration and tail docking do not cause sufficient pain to warrant using pain relief, respectively. Time and cost were identified as major barriers to providing pain relief. In the unadjusted logistic regression analyses, respondents who were female, had high levels of education, had been farming < 20 years, who believed lambs experienced high levels of pain following the procedures, and who believed pain lasted longer than 6 hours, were more likely to indicate willingness to use pain control devices. CONCLUSION AND CLINICAL RELEVANCE: Our results suggest very few New Zealand sheep farmers currently provide lambs with pain relief following tail docking or castration. This is likely due to the perception that the procedures are not painful enough to warrant pain relief, and concern over time and cost. This highlights the need to educate farmers about lamb pain and distress following tail docking and castration, and its negative impact on animal welfare. Farmers also need pain relief techniques and tools that can be administered simultaneously with these procedures to save time and labour cost.

Cross-sectional survey of barriers and opportunities for engaging backyard poultry producers and veterinarians in addressing poultry health.

AIMS: To assess the current level of engagement between backyard poultry keepers and veterinarians in New Zealand; to understand the opportunities and barriers for improving access to poultry health care; and to gauge the interest of backyard poultry keepers in participating in a voluntary national poultry health information system. MATERIALS AND METHODS: Backyard poultry were defined as any bird species kept for non-commercial purposes. Separate cross-sectional surveys were administered to backyard poultry keepers and veterinarians in New Zealand over 12-week periods starting 22 March 2021 and 03 May 2021 respectively. The veterinarian survey was advertised in the monthly update e-mail from the Veterinary Council of New Zealand, while the survey for backyard poultry keepers was advertised on various online platforms that focus on raising backyard poultry. Results for quantitative variables were reported as basic descriptive statistics, while qualitative free-text responses from open-ended questions were explored using thematic analysis. RESULTS: A total of 125 backyard poultry keepers and 35 veterinarians completed the survey. Almost half (56/125; 44.8%) of backyard poultry keepers reported that they had never taken their birds to a veterinarian, with common reasons being difficulty finding a veterinarian, cost of treatment, and perceptions that most visits result in the bird being euthanised. The majority (113/125; 90.4%) of backyard poultry keepers reported that a general internet search was their primary source for poultry health advice. However, it remains unclear if owners were satisfied with the advice found online, as many cited that having access to reliable health information would be an incentive for registering with a poultry health information system. Of the veterinarian responses, 29/35 (82.9%) reported treating an increasing number of poultry in the last 5 years, although many (27/35; 77.1%) suggested they would be hesitant to increase their poultry caseload due to concerns over their lack of knowledge and confidence in poultry medicine; a lack of clinic resources to treat poultry; concerns over the cost-effectiveness of treatments; and a general feeling of helplessness when treating poultry, with most consultations being for end-stage disease and euthanasia. CONCLUSION: The results of this study highlight opportunities for increased engagement between backyard poultry keepers and veterinarians, including making available accurate poultry health information and providing veterinarians with improved training in poultry medicine. The results also support the development of a poultry health information system in New Zealand to further enhance health and welfare in backyard poultry populations.Abbreviations: MPI: Ministry for Primary Industries.

Practices and opinions of New Zealand veterinarians regarding control of bovine viral diarrhoea.

AIMS: To explore recommendations that New Zealand veterinarians make for diagnosing and managing bovine viral diarrhoea (BVD) in cattle herds under different clinical scenarios and their opinions towards potential barriers and opportunities for implementing BVD control programmes in New Zealand. METHODS: A cross-sectional survey of registered veterinarians in New Zealand was conducted in 2019. Respondents were asked about the approaches they would use to manage BVD under different clinical scenarios as well as their opinions on national BVD control. A subset of veterinarians completed a more in-depth survey providing additional free-text responses on a range of different BVD topics. Descriptive statistics were provided for all quantitative study variables and the free-text responses were also analysed to generate further insights into veterinarians' perceptions towards BVD management. RESULTS: The cross-sectional survey was completed by 101 of an estimated 870 (11.6%) cattle veterinarians. Thirty-five veterinarians completed the in-depth survey. There was wide variation in the BVD diagnostic testing and vaccination protocols that respondents recommended under different clinical scenarios. Annual bulk milk BVD testing was perceived as a valuable tool for initiating BVD discussions with dairy farmers. Respondents indicated that beef farmers were more difficult to engage in BVD control largely due to the logistical challenges of yarding cattle at the appropriate times to implement interventions, with many farmers only contacting veterinarians after experiencing a BVD outbreak Most respondents (91/101; 90%) believed it was possible to eradicate BVD from New Zealand, but cited lack of farmer awareness and poor compliance with management recommendations as significant barriers. The measure with the most support for inclusion in a compulsory national eradication programme was requiring farmers to declare the status of their animals prior to sale while the least supported measure was requiring farmers to double fence boundaries to prevent nose-to-nose contact with neighbouring stock. Although respondents highlighted the need for farmers and industry to support any national eradication programme in order for it to be successful, there was also recognition that veterinarians could be more pro-active in engaging with farmers particularly in discussions around the economics of BVD. CONCLUSIONS AND CLINICAL RELEVANCE: While the survey respondents appeared to be highly supportive of BVD control, it was perceived that financial and logistical barriers existed that could impede farmer engagement. Further extension efforts may be needed to ensure that veterinarians are presenting clear and consistent recommendations about BVD management to farmers.Abbreviations: BVD: Bovine viral diarrhoea; NAIT: National Animal Identification and Tracing System; PI: Persistently infected.

Veterinary technology graduates' perceptions of their education and subsequent employment experiences.

AIMS: To describe the current employment status of Bachelor of Veterinary Technology (BVetTech) graduates in New Zealand, to assess how well they felt that their degree programme had prepared them for practice, and to explore their experiences in their current job roles. METHODS: All 195 individuals who completed the BVetTech degree at Massey University between 2011 and 2018 were invited to participate in a cross-sectional survey regarding their education and employment experiences. Descriptive statistics were provided for all quantitative study variables and thematic analysis was performed on the free-text survey comments. RESULTS: The survey was completed by 125/195 (64.1%) BVetTech graduates. Of these, 96/125 (76.8%) were engaged in full-time or part-time veterinary work. The most common work environments were small animal practice (55/125; 44.0%) and mixed animal practice (19/125; 15.2%). The median reported annual salary was NZ$42,640 (mean $45,817; min $34,515; max $80,000) while the median reported hourly wage was NZ$20.00 (mean $21.01; min $17.70; max $27.00). Most respondents generally agreed with statements that their degree had prepared them well for different aspects of their subsequent work as veterinary technologists with "understanding the scientific rationale behind clinical decisions in practice" and "gaining hands-on practical experience that directly linked with their classroom learning" highlighted as being the best aspects of their education. However, respondents expressed the need for more training in client interactions and veterinary business management. Common themes that emerged when respondents were asked to describe the best things about their work were "forming relationships with animals, clients, and co-workers," "making a meaningful difference through their work," and "having opportunities to use and develop their skills" while the worst things about their job were "underutilisation of their skills," "poor pay in relation to their education and skill," and "compassion fatigue arising from dealing with euthanasia and difficult clients." Another common theme across free-text questions was the lack of employer awareness about the capabilities of a veterinary technologist. CONCLUSIONS AND CLINICAL RELEVANCE: Recent BVetTech graduates were generally satisfied with their educational experience, but perceived that employers underestimated the value of their training and consequently underutilised their skills. This highlights the need for additional research to better estimate the value of veterinary technologists to the New Zealand animal health industries as well as additional extension efforts to increase awareness amongst employers about the scope of responsibilities that veterinary technologists are legally able to perform in practice.

Practices, preferences, and opinions of New Zealand veterinarians towards continuing professional development.

Aims: To describe the current practices and preferences of New Zealand veterinarians towards continuing professional development (CPD), explore factors acting as perceived barriers to CPD engagement, and identify opportunities for reforming the current CPD regulations. Methods: A cross-sectional survey of all veterinarians registered with the Veterinary Council of New Zealand (VCNZ) was conducted in October 2019. Descriptive statistics were provided for all quantitative study variables and thematic analysis was performed on the free-text survey comments to identify key issues regarding the current CPD regulations in New Zealand. Results: Complete survey responses were provided by 222/3,484 (6.4%) registered veterinarians. Most respondents (153/222; 68.9%) were satisfied with the amount of CPD completed and spent a mean of $2,511 (median $2,000; min $0; max $20,000) on CPD activities each year. The most popular CPD formats were those involving collegial interaction including conference and skills training workshops. The choice of CPD activities was most commonly influenced by interest in the topics and the desire to become more competent in their work while the main barriers were difficulties fitting CPD around work and family commitments. There were 164 (73.9%) respondents who cited at least one occasion in the previous 12 months where participating in CPD caused them to modify their existing practices. Thematic analysis of the free-text comments revealed several major themes related to the administrative burden of recording CPD activities under the current regulatory framework, and the need to develop CPD plans tailored towards the unique circumstances and goals of individual veterinarians. Respondents also expressed concerns over the reliability of using CPD record audits for evaluating professional competency. Factors identified as being the most helpful for improving the current CPD framework were simplifying the CPD points categories and developing a mechanism to record and share CPD activities in real-time. Conclusions: While most respondents felt there was significant value in completing CPD, the current regulatory framework was perceived to be administratively burdensome and inflexible in allowing them to tailor CPD activities to match their unique employment situation, learning style and professional goals. Clinical relevance: Providing resources that could assist veterinarians to design and implement tailored CPD programmes may improve professional and personal outcomes. However, further research is needed to develop more effective mechanisms for identifying veterinarians who are not performing competently without placing excessive administrative burdens on those who are.

Experiences of employers, work colleagues, and mentors with new veterinary graduates and preferences towards new graduate support programmes.

Aims: To describe the experiences of employers, work colleagues, and mentors who have recently worked with new veterinary graduates in New Zealand, explore factors influencing perceptions of new graduate performance, and identify opportunities for providing better support to new graduates and their employers. Methods: All veterinarians registered with the Veterinary Council of New Zealand (VCNZ) were invited to participate in a cross-sectional survey. Descriptive statistics were calculated for all study variables and a mixed-effects multivariable logistic regression model was constructed to explore factors associated with perceptions of new graduate performance. Thematic analysis was performed on free-text comments to identify key issues with new graduate support. Results: The survey was completed by 83 veterinarians with 68 (81.9%) providing information on 95 individual new graduates they had mentored. New graduates exceeded expectations in their ability to research cases and communicate with colleagues while time management and awareness of financial issues were highlighted as weaknesses. The mean total time respondents spent supervising new graduates during their first year was 166.8 (median 95; min 0; max 852) hours. New graduates who were not considered the best applicants for the job and those who had left their job were 6.3 (95% CI = 2.11-11.8) and 5.4 (95% CI = 1.55-19.0) times, respectively, more likely to be rated as performing below expectations. Thematic analysis revealed major themes related to the inadequate preparation of students in veterinary school, employers lacking adequate training and resources to supervise new graduates, and intergenerational differences in work ethic and expectations, which may be contributing to burnout and dissatisfaction for new graduates and their employers. Components of new graduate support programmes that were perceived to be most helpful were having regular meetings between the supervisor and employee to discuss performance and wellbeing, having compulsory sessions with an experienced veterinarian for career advice, and having non-compulsory checklists of technical and non-technical skills to guide professional development planning. However, there was varying levels of support for including these measures in a formal new graduate support programme. Conclusions: While respondents highlighted many challenges faced by new graduates and their employers, there was often disagreement about the root cause of the problem and potential solutions. Clinical relevance: Providing non-compulsory checklists to help employers work with new graduates to develop tailored professional development plans and support structures within their unique practice environment may result in more positive experiences as new graduates transition from student to independent practitioner.

Temporal trends in bulk tank milk antibody ELISA and PCR test results for bovine viral diarrhoea in New Zealand pastoral dairy herds.

Aims: To describe temporal trends in bulk milk antibody ELISA and PCR testing for bovine viral diarrhoea (BVD) in New Zealand pastoral dairy herds and to assess the use of historical accession data to predict herd-level BVD incursions. Methods: Data on all diagnostic testing of bulk milk for BVD performed by the Livestock Improvement Corporation (Hamilton, NZ) over eight lactation seasons from 1 June 2010 to 31 May 2018 were analysed. This included anonymised herd identification, geographic location, herd size, sample collection date, sample to positive (S/P) ratio for antibody ELISA results, and cycle threshold values for PCR detecting viral RNA. Multivariable logistic regression was used to explore the relationship between historical accession data and the risk of herds having at least one positive bulk milk PCR test result in the 2017 season. Results: There were 156,034 bulk milk BVD diagnostic testing accessions for 10,495 uniquely identified dairy herds over the 8-season period. The prevalence of tested herds with at least one positive bulk milk PCR test result decreased from 14.6% (407/2,786) in the 2010 season to 5.6% (355/6,309) in the 2017 season with similarly marked declines in S/P ratios. In the 2017 season, 2,961/6,309 (46.9%) herds had S/P ratios greater than the 0.75 cut-off value indicating recent or active BVD virus transmission within the herd while 1,422/6,309 (22.5%) herds were classified as having negative or low S/P ratios. Herds that cleared BVD from the milking herd experienced a mean decline in S/P ratio of 0.11 units per year (min 0.05; max 0.18). In the multivariable analysis, the overall incidence risk of herds experiencing a BVD incursion in the 2017 season was 3.8% (146/3,848) and there were three significant predictors in the final model: herd size, PCR status in the 2014 season, and change in S/P ratio between the 2014 and 2015 seasons. The area under the receiver operating curve for the final model was 0.695 indicating poor discrimination. Conclusions and clinical relevance: The prevalence of dairy herds in New Zealand with positive bulk milk PCR test results and high S/P ratios has decreased over time, suggesting fewer herds are actively infected with BVD and that herd immunity may also be declining. Although monitoring trends in bulk milk test results provides useful information on changes in individual herd status, it is difficult to accurately predict when new incursions will occur and farmers should continue to maintain good biosecurity.

Evaluating the cost-effectiveness of diagnosing and treating phantom cows in seasonal-calving dairy herds.

The objective of this study was to explore the cost-effectiveness of using a progesterone-based synchrony program to manage phantom cows on seasonal-calving dairy farms. Phantom cows were defined as cows that had been artificially inseminated ≤14 d after mating start date (MSD), were not subsequently detected in estrus, and were diagnosed nonpregnant at a pregnancy diagnosis conducted approximately 49 d after MSD. Decision-tree analysis was applied to data from a previous randomized controlled trial in which phantom cows (n = 378) from spring-calving dairy farms were randomly allocated to an untreated control group or were immediately treated with a 10-d progesterone-based synchrony program with fixed-time artificial insemination. The net economic return of treating all cows presented by the farmer for pregnancy diagnosis that were diagnosed nonpregnant was compared with no intervention. The net return was calculated per cow present at MSD because the decision trees followed all cows present at MSD through to mating end date to account for farmers inadvertently presenting ineligible cows for pregnancy diagnosis and possible treatment. Probabilities, costs, and benefits of reproductive outcomes were based on published data and expert opinion. The effects of key variables on the economic return were tested by sensitivity analysis. Phantom cow intervention delivered a net return of NZ$4.451 (at the time of the study, NZ$1 = US$0.6629) per cow present at MSD. The sensitivity of pregnancy diagnosis, the proportion of ineligible cows presented by the farmer for pregnancy diagnosis, and the prevalence of phantom cows were highly influential on the net economic return from phantom cow intervention. These findings suggest that treatment of phantom cows in seasonal-calving dairy farms using a progesterone-based synchrony program is economically viable based on the current model assumptions. Accurate cow selection and pregnancy diagnosis are essential to success, and veterinarians and animal health advisors can improve the net economic return of intervention by selecting farms likely to have a higher prevalence of phantom cows based on the presence of observable risk factors.

Estimating the level of disease risk and biosecurity on commercial poultry farms in New Zealand.

Aims: To collect baseline data on the contact risk pathways and biosecurity practices of commercial poultry farms in New Zealand, investigate the relationship between the farm-level disease contact risks and biosecurity practices, and identify important poultry health concerns of producers. Methods: A cross-sectional survey of all registered New Zealand commercial poultry operations was conducted in 2016 collecting information on farm demographics, biosecurity practices, and contact risk pathways. Survey responses were used to generate an unweighted subjective disease risk score based on eight risk criteria and a subjective biosecurity score based on the frequency with which producers reported implementing seven biosecurity measures. Producer opinions towards poultry health issues were also determined. Results: Responses to the survey response were obtained from 120/414 (29.0%) producers, including 57/157 (36.3%) broiler, 33/169 (19.5%) layer, 24/55 (44%) breeder, and 6/32 (19%) other poultry production types. Median disease risk scores differed between production types (p < 0.001) and were lowest for breeder enterprises. The greatest risk for layer and broiler enterprises was from the potential movement of employees between sheds, and for breeder enterprises was the on- and off-farm movement of goods and services. Median biosecurity scores also differed between production types (p < 0.001), and were highest for breeder and broiler enterprises. Across all sectors there was no statistical correlation between biosecurity scores and disease risk scores. Producers showed a high level of concern over effectively managing biosecurity measures. Conclusions: The uptake of biosecurity measures in the commercial poultry farms surveyed was highly variable, with some having very low scores despite significant potential disease contact risks. This may be related to the low prevalence or absence of many important infectious poultry diseases in New Zealand leading farmers to believe there is a limited need to maintain good biosecurity as well as farmer uncertainty around the efficacy of different biosecurity measures. Further research is needed to understand barriers towards biosecurity adoption including evaluating the cost-effectiveness of biosecurity interventions.

An overview of dropped hock syndrome cases in New Zealand cattle.

Case history: Data were collected from 47 outbreaks of dropped hock syndrome (DHS) that were reported by veterinarians in New Zealand to the Ministry for Primary Industries between October 2012 and August 2017. There were 181 affected dairy cows from 44 farms. Of those with records, all 86 were aged between 2-3 years-old, and 4/94 (4%) were Friesian, 56/94 (60%) were Jersey and 33/94 (35%) were Jersey/Friesian cross. Of the 47 outbreaks, 45 (96%) occurred during winter and 37 (79%) in the South Island.Clinical findings: Of 151 cases with records, hindlimb weakness (117 cows), shortened gait (112 cows) and dropped hocks (106 cows) were most commonly reported, with 110 cases being bilaterally affected. The level of diagnostic work-up and the data recorded by veterinarians for each outbreak were highly variable. Creatine kinase and aspartate aminotransferase activities were reported for 22 cases and were within normal ranges for cows with mild disease but increased in cows with severe disease. Concentrations of Cu in serum and liver were below normal for 13/22 and 9/10 cows, respectively, from six outbreaks. Of 41 cows with records for clinical outcomes, 12 had complete resolution, 18 had partial resolution, and 11 had no resolution.Pathological findings: Post-mortem data were available from 26 cases. Muscle necrosis and haemorrhage of the origin of the gastrocnemius muscle were the key gross findings. In 14 cows with records for muscle histopathology, myodegeneration and recent haemorrhage were observed, and connective tissue pathology was reported to predate muscular pathology in seven cases.Diagnosis: DHS appeared to be a degenerative rather than inflammatory condition primarily affecting the connective tissue of the hind limb, especially at the dense collagen interfaces of the gastrocnemius. Although no evidence of neuropathy was found, this cannot definitively be ruled out as a potential cause.Clinical relevance: A more standardised and systematic approach to investigating cases and recording case data is required to make robust inferences about the aetiology, risk factors, and treatment interventions for DHS.

Experiences of recent veterinary graduates in their first employment position and their preferences for new graduate support programmes.

Aims: To explore the experiences of recent veterinary graduates in their first employment position, to investigate risk factors for leaving this position, and to identify their preferences towards new graduate support programmes.Methods: All 693 individuals who completed their veterinary degree and registered with the Veterinary Council of New Zealand between May 2014 and May 2019 were invited to participate in a cross-sectional survey regarding their employment experiences. Descriptive statistics were calculated for all study variables and a multivariable logistic regression model was constructed to explore factors associated with increased risk of new graduates leaving their first position. Thematic analysis was performed on the free-text comments to identify key issues with new graduate support.Results: The survey was completed by 162/693 veterinarians (23.4%). Of 153 respondents who provided information on their first employment position, 61 (39.9%) commenced their veterinary career in companion animal practice, 44 (28.8%) in mixed animal practice, 36 (23.5%) in large animal practice, and 12 (7.8%) worked in another veterinary discipline. Most respondents (124/153; 81.0%) were rostered for after-hours emergency shifts during their first year with variable levels of support from their practice. Among 72 respondents (44.4%) who had left their first job, the mean length of employment was 1.4 (median 1; min 1; max 4) years. The most common reasons reported for leaving were a toxic practice culture and lack of adequate support. The risk of leaving was increased by being put in situations they could not handle (OR 5.26; 95% CI = 1.49-20.6) and employers that did not regularly check their wellbeing (OR 5.08; 95% CI = 1.52-18.9). Only 56/144 (38.9%) respondents and 30/144 (20.8%) respondents supported introducing compulsory checklists of technical and soft skills, respectively. Providing regular feedback, creating a supportive practice culture, setting reasonable workload expectations, providing clinical and professional advice, and developing tailored skills development plans were identified as key areas that employers of new graduates should address.Conclusions: Lack of appropriate mentoring and toxic practice cultures were the most common reasons for new graduates leaving their first job. Although respondents identified that employers should provide new graduates with better support, most were not supportive of introducing a compulsory programme.Clinical relevance: To help new graduates transition into their first professional veterinary roles, employers should ensure that new graduates are only placed in situations that they can handle competently and check regularly on their mental and physical wellbeing.

Cross-sectional survey of surgical techniques used to perform dog and cat spays in New Zealand veterinary practice.

Aims: To describe the variation in surgical techniques used by veterinarians to perform routine dog and cat spays in first-opinion veterinary practice in New Zealand, and how these techniques differed with the number of years since the veterinarian graduated.Methods: A cross-sectional survey of veterinarians registered to practice in New Zealand was conducted online between 1 April and 30 May 2018. Respondents were asked their year of graduation and about the procedures, they would use to perform a routine spay of a healthy, 5 kg, young adult, female domestic shorthair cat, and a healthy, 20 kg, young adult, female mixed-breed dog. The number of years since graduation was calculated by subtracting the reported year of graduation from 2018.Results: Overall, 282 respondents provided details about dog spays, and 361 about cat spays, and the median number of years since graduation was 14 (min 0, max 50). Only 54/282 (19.1%) respondents performing dog spays and 43/361 (11.9%) performing cat spays wore a surgical cap, gown, mask, and gloves. For dog spays, 278 (98.6%) respondents used a ventral midline approach and 147 (52.1%) used manual exteriorisation of the uterus. Most used two clamps (168; 59.6%) and used two encircling ligatures (152; 53.9%) for removal of the uterus. For cat spays, 254 (70.4%) respondents used a ventral midline approach and 313 (86.7%) used a spay hook for exteriorising the uterus. Most used two clamps (250; 69.3%) with one encircling ligature (213; 59.0%) for removal of the uterus. Simple interrupted external or intradermal patterns were mostly used for skin closure for both dog and cat spays. For cat spays, the percentage of respondents using the ventral midline approach decreased with increasing years since graduation (p < 0.001). For both dog and cat spays, the percentage of respondents using two encircling ligatures and transfixation ligation of the uterus, and using a simple continuous suture pattern for the closure of the abdomen, decreased with number of years since graduation (p < 0.05).Conclusions and clinical relevance: Veterinarians responding to this survey used a wide range of techniques to perform routine dog and cat spays, some of which were associated with the number of years since graduation. It may be beneficial to provide veterinarians with resources to reflect on their current approaches for performing routine spays. However further research is needed to determine whether any surgical techniques are superior to others.

Preliminary analysis of post-adoption outcomes for kittens and adult cats rehomed through a New Zealand animal shelter.

Aims: To determine the frequency of different types of health and behavioural problems observed in the first month after adoption in kittens and adult cats rehomed through an animal shelter in New Zealand, to assess satisfaction of adopters and to determine the preferences of adopters for provision of post-adoption support.Methods: The adopters of kittens and cats from an animal shelter in Auckland, New Zealand between 15 October 2016-4 December 2016 were invited to complete a survey 1 week and 1 month after adoption. Respondents were asked about how well the animal was settling into the household, whether they had observed any health or behavioural problems, and what their preferences were for receiving post-adoption support.Results: Data from at least one survey were available for 83/115 (72.2%) kittens and 70/155 (45.6%) adult cats, with 39/115 (34%) adopters of kittens and 35/155 (23%) adopters of adult cats completing surveys at both 1 week and 1 month after adoption. By 1 month after adoption 57/60 (95%) adopted kittens and 40/53 (75%) adopted adult cats had settled well into their new home. At 1 month after adoption 28/60 (47%) kittens and 26/53 (49%) cats had ≥1 reported behavioural problem, and 16/60 (27%) kittens and 18/53 (34%) cats had ≥1 reported health problem. The most common problem behaviours for kittens were episodes of hyperactivity and scratching household items, and for adult cats were spending most of the time hiding and scratching household items. The most common health problems for kittens were eye problems and sneezing or a runny nose, and for adult cats were sneezing or a runny nose. Amongst respondents, the most helpful support for recent adopters was considered to be an email or phone call 1 month after adoption from the animal shelter.Conclusions and clinical relevance: Although many adopters reported health and/or behavioural issues in their adopted kittens and adult cats, most issues were generally mild and the adopters were generally satisfied with their animals. Providing new adopters with advice about managing common health and behavioural issues such as upper respiratory disease and scratching household items may increase satisfaction with adoptions.

Serological evidence for exposure to bovine viral diarrhoea virus in sheep co-grazed with beef cattle in New Zealand.

Aims: To determine whether sheep that co-grazed with cattle that were suspected to be positive for bovine viral diarrhoea (BVD) virus had serological evidence of exposure to the virus.Methods: Eighteen commercial farms that routinely co-grazed cattle and sheep in the same paddocks were recruited through purposive sampling. The recruiting veterinarians identified nine farms with cattle herds that were known or highly suspected to be positive for BVD and nine farms that were considered to be free of BVD. Blood samples were taken from 15 ewes aged 1 year on each farm and samples were submitted to a commercial diagnostic laboratory to test for antibodies against pestiviruses using an ELISA. All samples that were positive were then tested using a virus neutralisation test (VNT)for antibodies against BVD virus.Results: Of the 270 blood samples, 17 were positive for pestivirus antibodies by ELISA and these originated from two farms that were known or suspected to have BVD virus-positive cattle. None of the samples from the nine flocks co-grazed with cattle herds that were known or suspected to be BVD virus-negative were positive for pestivirus antibodies. Within the two positive farms, 2/15 samples from the first farm and 15/15 samples from the second farm were antibody-positive. When the 17 positive blood samples were submitted for VNT, all 15 samples from the second farm tested positive for BVD virus antibodies with the highest titre being 1:512.Conclusions and clinical relevance: In this small sample of New Zealand sheep and beef farms with suspected BVD infection in cattle, there was evidence of pestivirus exposure in co-grazed sheep. Although we were unable to confirm the origin of the exposure in these sheep, these findings highlight that farmers who are trying to eradicate BVD from their cattle should be mindful that the infection may also be circulating in sheep, and both populations should be considered a possible risk to each other for generating transient and persistent infections. Further work is needed to estimate the true prevalence of New Zealand sheep flocks that are affected by BVD and the associated economic impacts.

Practices and opinions of New Zealand beef cattle farmers towards bovine viral diarrhoea control in relation to real and perceived herd serological status.

Aims: To investigate the seroprevalence of infection with bovine viral diarrhoea (BVD) virus among 75 beef herds and seroconversion in cattle during early pregnancy, and to determine the practices and opinions of farmers towards BVD control and their association with real and perceived herd serological status.Methods: Blood samples were collected before mating in 75 beef herds across New Zealand from 15 unvaccinated heifers that had delivered their first calf that season. Serum samples were tested for BVD antibodies using ELISA individually, and after pooling samples for each farm. Animals that were antibody-negative were retested at either pregnancy diagnosis or weaning. Farmers were asked to complete a detailed survey about herd demographics, BVD testing and vaccination practices, and opinions towards national BVD control.Results: Based on the pooled serum antibody ELISA results, there were 28/75 (37%) negative herds, 15/75 (20%) suspect herds, and 32/75 (43%) positive herds. Of 1,117 animals sampled 729 (65.3%) tested negative for BVD virus antibodies; when retested, 47/589 (8.0%) animals from 13/55 (24%) herds had seroconverted. Among 71 famers providing survey responses 11 (15%) believed their herd was infected with BVD, 24 (34%) were unsure and 36 (51%) did not think their herd was infected. Only 19/71 (18%) farmers had performed any BVD testing within the past 5 years and 50/70 (71%) had not vaccinated any cattle for BVD. Support for national BVD eradication programme was strong in 51/71 (56%) respondents, but the biggest challenge to BVD control was considered to be famer compliance. Compared to farmers who did not think their herd was infected, more farmers who thought BVD was present in their herds had previously tested for BVD, would consider testing all replacement calves, and would support establishing a national BVD database; fewer would consider purchasing BVD tested or vaccinated cattle only.Conclusions and clinical relevance: Only 15% of the beef farmers in this study believed their herds were infected with BVD virus and few of them had undertaken BVD screening. Nevertheless many were supportive of implementing a national BVD control programme. It is likely that the lack of farmer awareness around BVD and the failure of farmers to recognise the potential impacts in their herds are hindering progress in controlling the disease in New Zealand. There are opportunities for New Zealand veterinarians to be more proactive in helping beef farmers explore BVD management options.

Cross-sectional survey of pet ownership, veterinary service utilisation, and pet-related expenditures in New Zealand.

Aims: To describe the demographics of and predictors for pet ownership, reasons for visiting a veterinarian, and pet-related expenditure in pet owners in New Zealand. Methods: A cross-sectional online survey was conducted from 18-22 June 2015 using a permission-based panel of New Zealand residents aged ≥18 years. Questions included demographics of respondents, number of pets and reasons for owning or not owning pets, number of visits and reasons for visiting a veterinarian, and pet-related expenditure. Results: Of the 1,572 respondents who completed the survey, 1,013 (64.4%) owned ≥1 pet. Of these, 443 owned dogs, 696 cats, 32 horses, 103 birds, 55 rabbits, and 159 owned fish. Companionship was the most common reason for getting dogs, cats, and birds; horses were mostly owned as a hobby, rabbits to provide fun for children, and fish as a source of relaxation. The majority of dog, cat, and rabbit owners considered their pets to be family members; horse owners almost equally considered their horses a hobby or a family member. The odds of pet ownership increased for respondents from a rural region, having a higher household income, having children and being female. Overall, 711/1,013 (70.2%) pet-owning respondents had taken ≥1 animal to the veterinarian in the previous year, with the most common reasons being for vaccination or annual check-ups or health issues. Respondents who considered their pets trusted companions, had a higher income, and owned dogs or cats compared with other species, were most likely to have taken their pet to a veterinarian. The greatest pet-related expenditure for all species was food. The median yearly veterinary expenditure was $200-499 by dog owners, $100-199 by cat owners, and <$100 by horse, bird, rabbit, and fish owners. The best source of information for pet-related issues was considered to be veterinarians by 724/1,001 (72.3%) owners, and the internet by 509/1,001 (50.8%) owners. Conclusions: Among survey respondents, pet ownership was common and pets filled a variety of roles in the household. Pet owners reported spending considerable amounts of money on their pets each year, but some of them may be underutilising veterinary services despite veterinarians being considered as valuable sources of information about pet-related issues.

A survey of opinions towards dog and cat management policy issues in New Zealand.

Aims: To describe the opinions of respondents to an online survey on desexing, microchipping and pet registration, and the management of cats, and aggressive dogs in New Zealand. Methods: A cross-sectional survey was conducted online from 18-22 June 2015 using a permission-based panel of New Zealand residents aged ≥18 years. Questions included demographics of respondents, number of dogs and cats owned, and opinions on desexing, microchipping, pet registration, management of cats and aggressive dogs. Results: Of the 1,572 survey respondents, 216 (13.7%) owned ≥1 dog and ≥1 cat, 227 (14.4%) owned ≥1 dog and no cats, 480 (30.5%) owned ≥1 cat and no dogs, and 559 (35.6%) did not own any pets. The majority of dogs (456/613; 74.8%) and cats (974/1,045; 93.2%) were desexed. The most common reasons for not desexing pets were cost, feeling that it was not needed, or keeping the dog for breeding. Of the 613 dogs, 557 (90.9%) were registered with the local council, and 434 (71.0%) were microchipped, but only 290 (47.3%) were registered in the national database. Of the 1,045 cats, 326 (31.2%) were microchipped and 279/486 (57.4%) owners felt that it was unnecessary. Of the 1,572 respondents, 947 (60.2%) were unaware of stray cats in their local community, and 479 (30.5%) stated that local councils, or animal welfare organisations (546/1,572; 34.7%) should be responsible for managing strays. Among all 1,572 respondents, 787 (50.1%) thought stray cats should be assessed and subjected to euthanasia. Compared with non-pet owners, a lower percentage of cat owners agreed that cats should be confined (p < 0.001). When asked to choose the most appropriate course of action for dogs that had bitten people or other animals, 849 (54.0%) and 820 (52.5%) respondents, respectively, agreed that the dog should be assessed by an expert who would then determine the appropriate action. Compared with non-pet owners, a lower percentage of dog owners supported registration and education of dog owners, aggressive dogs being destroyed, and giving more power to local councils (p < 0.05). Conclusions: The results highlight opportunities to improve owner compliance with desexing, microchipping and registration of dogs and cats. Opinions towards management of stray cat and aggressive dogs varied between pet owners and non-owners. Further research is needed to better understand how to engage the public in important dog and cat management policy issues.

Owner perceptions and management of the adverse behavioural effects of fireworks on companion animals: an update.

Aims: To provide updated results on the adverse behavioural effects of fireworks on companion animals in New Zealand, measures that owners use to mitigate these effects, and opinions on a ban on the sale of fireworks. Method: A cross-sectional survey of companion animal owners in New Zealand was conducted between 2 November and 5 December 2016 using an online survey. The survey was modelled after a similar study conducted in 2006. Owners were asked to provide information on the types and severity of behaviours observed in their animals that were frightened by fireworks, what they did for their frightened animals and whether they would support a ban on the sale of fireworks. Results: There were 4,293 respondents who completed the online survey and they owned 15,871 companion animals, of which 11,750 (74.4%) were frightened of fireworks. For the 7,464 fearful animals with individual data available, the most commonly reported adverse behaviours were hiding (5,287; 70.8%), shivering (4,058; 54.3%) and cowering (3,324; 44.5%). Owners reported that 345 animals had been physically injured as the result of fireworks. Of 3,682 owners with frightened animals, 2,649 (71.9%) had not sought help or treatment for their animal. Frightened animals were mostly kept inside (3,479/7,464; 46.%) or comforted (2,112/7,464; 28.2%). Of all 4,325 respondents, 3,631 (84.0%) were supportive of a ban on the private sale of fireworks, with 370 (8.6%) against and 315 (7.3%) undecided. Owners with ≥1 animal that was fearful towards fireworks were more likely to support a ban (3,137/3,412; 91.9%) than owners whose animals were not afraid (466/561; 83.1%) (OR = 2.32; 95% CI = 1.80-2.98). Conclusion and Clinical Relevance: Among respondents to this survey, many owners of companion animals reported that their animals were adversely affected by fireworks, but few of them sought advice about strategies to mitigate the impacts. The majority of respondents supported a ban on the private sale of fireworks. Campaigns to raise public awareness of treatment strategies for managing fear behaviours during anticipated fireworks displays may be beneficial.
