RESUMO

The freshwater and marine ornamental fish industry is a primary route of hazard introduction and emergence, including aquatic animal diseases and non-native species. Prevention measures are key to reducing the risk of hazard incursion and establishment, but there is currently little understanding of the biosecurity practices and hazard responses implemented at post-border stages of the ornamental fish supply chain. This study addresses this knowledge gap, using questionnaires to collate information on actual biosecurity behaviours and hazard responses practised by ornamental fish retailers and hobbyist communities in England. Actual behaviours varied considerably within retailers and hobbyists, suggesting that reliance on preventative practices by individuals in the post-border stages of the ornamental fish supply chain is likely to be ineffective in minimizing the risk of hazard incursion and establishment. Resources should be allocated towards improving and enforcing robust pre- and at-border control measures, such as risk-based surveillance of ornamental fish imports at border controls. In addition, these findings should be used to implement targeted awareness-raising campaigns and help create directed training on biosecurity practices for individuals involved in the post-border stages of the ornamental supply chain.

RESUMO

An understanding of the main causes of mortality among captive gorillas is imperative to promoting their optimal care, health, and welfare. A retrospective observational review of mortality among the European zoo-housed western lowland gorilla ( Gorilla gorilla gorilla) population from 2004 to 2014 was carried out. This is the first published study of mortality in this population. Relevant postmortem data were requested from each collection reporting a death during the study period. Age at death enabled grouping into discrete age categories. Deaths were classified according to cause. The main causes of death overall and for each age category and sex were identified. In total, 151 gorillas from 50 European collections died during the study period. Postmortem data were available for 119 (79%) of the deaths, of which 102 (86%) were classified by cause. Diseases of the digestive system were responsible for most (23%) deaths overall. Also of significance (each accounting for 15% overall mortality) were deaths due to external causes (especially trauma) among young gorillas and cardiovascular disease among adult and aged animals. Being a male gorilla was associated with an 8.77- and 5.40-fold increase in risk of death due to cardiovascular and respiratory disease, respectively. Death due to external causes was 4.45 times more likely among females than males. There was no statistically significant difference in life expectancy between male and female gorillas. The authors conclude that further work is needed to understand risk factors involved in the main causes of death and suggest a need for standardization with regard the approach to postmortem examination and data collection, sample collection, and storage across European zoos.

RESUMO

BACKGROUND: Data extracted from electronic patient records (EPRs) within practice management software systems are increasingly used in veterinary research. The use of real patient data gives the potential to generate research that can readily be applied to clinical practice. The use of veterinary EPRs for research in the United Kingdom is hindered by the number of different Practice Management System (PMS) providers used by practices, as obtaining and combining data from different systems electronically can be problematic. The use of extensible mark up language (XML) to extract clinical data for research would potentially resolve the compatibility issues between systems. The aim of this study was to establish and validate a method for the extraction of small animal patient records from a veterinary PMS that could potentially be used across multiple systems. An XML schema was designed to extract clinical information from EPRs. The schema was tested and validated in a test system, and was then tested in a real small animal practice where data was extracted for 16 weeks. A 10 % sample of the extracted records was then compared to paper copies provided by the practice. RESULTS: All 21 fields encoded by the XML schema, from all of the records in the test system, were extracted with 100 % accuracy. Over the 18 week data collection period 4946 records, from 1279 patients, were extracted from the small animal practice. The 10 % printed records checked and compared with the XML extracted records demonstrated all required data was present. No unrequired, sensitive information e.g. costs or services/products or personal client information was extracted. CONCLUSIONS: This is the first time a method for data extraction from EPRs in veterinary practice using an XML schema has been reported in the United Kingdom. This is an efficient and accurate way of extracting data which could be applied to all PMSs nationally and internationally.

RESUMO

BACKGROUND: Wider adoption of reporting guidelines by veterinary journals could improve the quality of published veterinary research. The aims of this study were to assess the knowledge and views of veterinary Editors-in-Chief on reporting guidelines, identify the policies of their journals, and determine their information needs. Editors-in-Chief of 185 journals on the contact list for the International Association of Veterinary Editors (IAVE) were surveyed in April 2012 using an online questionnaire which contained both closed and open questions. RESULTS: The response rate was 36.8% (68/185). Thirty-six of 68 editors (52.9%) stated they knew what a reporting guideline was before receiving the questionnaire. Editors said they had found out about reporting guidelines primarily through articles in other journals, via the Internet and through their own journal. Twenty of 57 respondents (35.1%) said their journal referred to reporting guidelines in its instructions to authors. CONSORT, REFLECT, and ARRIVE were the most frequently cited. Forty-four of 68 respondents (68.2%) believed that reporting guidelines should be adopted by all refereed veterinary journals. Qualitative analysis of the open questions revealed that lack of knowledge, fear, resistance to change, and difficulty in implementation were perceived as barriers to the adoption of reporting guidelines by journals. Editors suggested that reporting guidelines be promoted through communication and education of the veterinary community, with roles for the IAVE and universities. Many respondents believed a consensus policy on guideline implementation was needed for veterinary journals. CONCLUSIONS: Further communication and education about reporting guidelines for editors, authors and reviewers has the potential to increase their adoption by veterinary journals in the future.

RESUMO

BACKGROUND: Veterinarians should be able to easily access scientific evidence about medical products and devices to incorporate into their clinical decision making. While the characteristics and quality of supporting information accompanying device and pharmaceutical advertisements have been studied in human medicine, little is known about this topic in veterinary medicine. The aim of this study was to characterise the supporting information provided by manufacturers of prescribed products, tests or devices in promotional material found in two commonly read UK-based veterinary publications. METHODS: Advertisements contained in issues of two veterinary periodicals published between July 2017 and July 2018 were analysed for advertisement and product characteristics and for items of accompanying information. Literature searches were conducted to assess the availability of peer-reviewed sources of information on advertised products. RESULTS: A minority (16%) of the 451 analysed advertisements were accompanied by references to peer-reviewed literature, despite the availability of scientific literature for many of the products advertised. LIMITATION: This study sampled two professional publications over a narrow time period. CONCLUSIONS: There may be insufficient evidence being provided to veterinary professionals via marketing features; this may limit the accessibility of scientific information for clinical decision making around advertised products.

RESUMO

BACKGROUND: The limited use of biosecurity practices by many in the farming community is likely to be due to a range of factors; further understanding of this issue is required. In this study, attitudes and behaviours of producers relating to selected biosecurity practices and the farming industry were studied by interviewing cattle farmers within a 100 km2 study area in north-west England using an interview-based questionnaire. RESULTS: Most producers appeared to be familiar with the broad concept of the term biosecurity, although risks due to indirect contacts, rather than direct (animal) contacts, were more frequently highlighted. Most producers felt the nominated biosecurity practices were in some way useful, however there was not always agreement between the usefulness of a practice and it being undertaken, and vice versa. In agreement with other studies conducted in the UK, farmers most preferred to obtain information and advice on biosecurity from private veterinarians, but also highlighted DEFRA as a source. CONCLUSIONS: This study highlights the importance of understanding the motivators and barriers behind the uptake of biosecurity practices on farms, as perceptions are variable. Further understanding of these issues is needed in order to more effectively communicate information in regards to herd health and disease prevention. By identifying differences in producers' attitudes, programs can be tailored specifically to individuals' needs.

RESUMO

BACKGROUND: There are a number of different methods that can be used when estimating the size of the owned cat and dog population in a region, leading to varying population estimates. The aim of this study was to conduct a systematic review to evaluate the methods that have been used for estimating the sizes of owned cat and dog populations and to assess the biases associated with those methods.A comprehensive, systematic search of seven electronic bibliographic databases and the Google search engine was carried out using a range of different search terms for cats, dogs and population. The inclusion criteria were that the studies had involved owned or pet domestic dogs and/or cats, provided an estimate of the size of the owned dog or cat population, collected raw data on dog and cat ownership, and analysed primary data. Data relating to study methodology were extracted and assessed for biases. RESULTS: Seven papers were included in the final analysis. Collection methods used to select participants in the included studies were: mailed surveys using a commercial list of contacts, door to door surveys, random digit dialled telephone surveys, and randomised telephone surveys using a commercial list of numbers. Analytical and statistical methods used to estimate the pet population size were: mean number of dogs/cats per household multiplied by the number of households in an area, human density multiplied by number of dogs per human, and calculations using predictors of pet ownership. CONCLUSION: The main biases of the studies included selection bias, non-response bias, measurement bias and biases associated with length of sampling time. Careful design and planning of studies is a necessity before executing a study to estimate pet populations.

RESUMO

Veterinarians (vets) appear to be one of the main gateways to biosecurity information for cattle farmers, and therefore are likely to affect the implementation of these measures. The aim of this study was to explore factors within the vet-farmer relationship that may impact on biosecurity being carried out on cattle farms in England. Interviews were conducted with cattle farmers and large-animal vets, with a focus on individuals deemed to implement good levels of biosecurity or those working with said individuals. The questions explored how each stakeholder felt the communication occurred between the groups and the perceived consequential influence each had on the other. Inductive Thematic analysis was used to explore participants' experience of vet-farmer interactions with a focus on areas of reciprocity between the two groups. Five primary themes were identified. Factors within the vet-cattle farmer relationship, such as trust and familiarity, which were interconnected with time spent with each other, appeared to influence the uptake of biosecurity measures on cattle farms. These factors purportedly impacted the ability of vet-farmer pairs to have cooperative discussions and enter into shared decision-making. In order to enhance animal and human health and welfare, these relationship factors might be key to the development of sustainable optimisation frameworks.

RESUMO

BACKGROUND: Understanding ethical challenges experienced in relation to adverse events is necessary to inform strategies that optimise patient safety and practitioner wellbeing. METHODS: A qualitative exploration of UK veterinary practitioners' experiences of adverse events was conducted. Data were collected via 12 focus groups and 20 interviews and analysed using an inductive coding technique. RESULTS: Questions surrounding acceptable boundaries of care, decision-making autonomy, personal scope of practice, use of evidence and speaking up about patient safety concerns were identified as ethically challenging to practitioners when endeavouring to prevent adverse events. Issues of appropriate accountability, interaction and communication with animal owners and the prioritisation of emotional and technical support for themselves and others were identified as ethically challenging in the aftermath of adverse events. LIMITATIONS: The qualitative nature of this study limits the generalisability of the findings. CONCLUSIONS: Ethical challenges are experienced by veterinary practitioners in relation to both preventing and responding in the aftermath of adverse events. Strategies that facilitate ethical decision making and reflection and encourage openness and learning from adverse events would likely improve patient safety and enhance practitioner wellbeing. Further research is needed to develop and implement support for practitioners who experience ethical challenges in relation to adverse events.

RESUMO

Veterinarians are trusted by farmers and play an important role in assisting them to implement biosecurity. More research is needed that particularly focuses on the impact of joint farmer-veterinarian discussions to further understand the role of communication in altering biosecurity behaviours. The aim of this study was to analyse joint dairy cattle farmer-veterinarian discussions about the adoption of on-farm biosecurity using novel social interaction methodologies. Farmer and veterinarian stakeholders were invited to take part in a face-to-face meeting. Introductory presentations were given, followed by separate facilitated veterinarian and farmer discussions. All stakeholders were brought together for a final facilitated group discussion which was audio recorded. Corresponding transcripts from the recordings were analysed via thematic and conversation analyses. Conversation analysis assessments such as turn taking, repair, sequence organisation, overlap and asymmetry were employed to investigate the nature of the conversation. Thematic analysis identified the negative repercussions of conflicting information or ineffective communication surrounding biosecurity implementation. The type of, and importance of, the relationship farmers had with veterinarians and other stakeholders was highlighted. The need to provide personalised biosecurity protocols on farms was identified. Four key factors were identified via conversation analyses. These included: 1) how the conversation facilitated agreement, 2) how the conversation allowed the farmer and veterinarian participants to learn from one another in real time, 3) how the discussion enabled participants to expand upon points they were making, and 4) how participants were able to obtain a greater understanding of the other participants' opinions, even without total resolution. Debate around the effective implementation of biosecurity measures on farms, explored using novel techniques, demonstrated the potential for utilising a discussive approach between veterinarians and farmers to lead to solutions not previously considered. Because of the nature of the discussion, conversation analysis resulted in an informative approach to encapsulating the nuanced dialogue between stakeholders, highlighting the potential of this analysis framework.

RESUMO

Evidence-based practices (EBPs) provide strategies to improve the health, welfare and productivity of animal species. However, ensuring implementation and uptake into routine practice of these EBPs is often challenging. In human health research, one approach used to improve uptake of EBPs is the use of theories, models and/or frameworks (TMFs), however the extent of the use of this approach in veterinary medicine is unknown. The aim of this scoping review was to identify existing veterinary uses of TMFs to inform the uptake of EBPs, and to understand the focus of these applications. Searches were conducted in CAB Abstracts, MEDLINE, Embase and Scopus, alongside grey literature, and ProQuest Dissertations & Theses. The search strategy consisted of a list of known existing TMFs that have been used to improve uptake of EBPs in human health, alongside more generic terminology for implementation and terminology relevant to veterinary medicine. Peer reviewed journal articles and grey literature detailing the use of a TMF to inform uptake of EBP(s) in a veterinary context were included. The search identified 68 studies that met the eligibility criteria. Included studies represented a diverse spread of countries, areas of veterinary concern and EBP. A range of 28 different TMFs were used, although the Theory of Planned Behaviour (TPB) predominated, featuring in 46% of included studies (n = 31). The majority of studies (n = 65, 96%) utilised a TMF with the aim to understand and/or explain what influences implementation outcomes. Only 8 studies (12%) reported the use of a TMF alongside/in conjunction with the actual implementation of an intervention. It is clear there has been some use to date of TMFs to inform uptake of EBPs in veterinary medicine, however it has been sporadic. There has been a heavy reliance on usage of the TPB and other similar classic theories. This has typically been to inform the understanding of factors, such as barriers and facilitators, that may influence the outcome of an implementation effort without then applying this knowledge to the actual implementation of an intervention. Furthermore, there has been a lack of acknowledgement of wider contextual factors and consideration of sustainability of interventions. There is clear potential to increase and expand the usage of TMFs to improve uptake of EBPs in veterinary medicine, including utilising a wider range of TMFs and developing interdisciplinary collaborations with human implementation experts.

RESUMO

BACKGROUND: The population of dogs and cats passing through rescue shelters may be subject to compromised welfare and increased susceptibility to disease. Little information exists to describe this population, its dynamics and associated management practices. The aim of this study was to carry out a census of un-owned cats and dogs in the UK in 2010, and to document the origins, destinations, husbandry and costs associated with the care of these animals. RESULTS: A sampling frame was constructed by searching the databases of publicly registered charities for England, Scotland and Wales, registers of breed rescues, and by internet searches of animal welfare websites. Overall, 2,352 contacts for 1,380 organisations were identified. All were sent a postal questionnaire asking for data on the number of dogs and cats housed, their origins and eventual outcomes, and details of husbandry between January 1st and December 31st 2010. For those which were registered charities (595), financial records were also obtained.A response rate of 38.8% was obtained. Overall, in 2010, 89,571 dogs and 156,826 cats entered the care of the participating organisations. Approximately half of these animals were relinquished by their owners. Other origins included being found as strays or confiscated for welfare purposes. Seventy-five per cent of dogs and 77.1% of cats were rehomed. The next most common outcome was euthanasia, accounting for 10.4% of dogs and 13.2% cats. For dogs and cats, 44.3% and 62% of participants respectively reported having a waiting list, which frequently exceeded the actual capacity of the facility. Over 19,000 people were involved in the care of these animals, on a paid or voluntary basis. Financial records were available for 519/595 (87.2%) of the registered charities, and their total expenditure in 2010 was £340 million. CONCLUSIONS: This study showed that a large number of animals become un-owned each year, which could have considerable implications for their welfare. Despite the resources expended, demand still exceeds capacity for many organisations, and a substantial number of both cats and dogs are euthanased, suggesting that further understanding of how and why these animals become un-owned is essential in order to target interventions.

RESUMO

A thorough search of the literature to find the best evidence is central to the practice of evidence-based veterinary medicine. This requires knowing which databases to search to maximize journal coverage. The aim of the present study was to compare the coverage of active veterinary journals by nine bibliographic databases to inform future systematic reviews and other evidence-based searches. Coverage was assessed using lists of included journals produced by the database providers. For 121 active veterinary journals in the "Basic List of Veterinary Medical Serials, Third Edition," the percentage coverage was the highest for Scopus (98.3%) and CAB Abstracts (97.5%). For an extensive list of 1,139 journals with significant veterinary content compiled from a variety of sources, coverage was much greater in CAB Abstracts (90.2%) than in any other database, the next highest coverage being in Scopus (58.3%). The maximum coverage of the extensive journal list that could be obtained in a search without including CAB Abstracts was 69.8%. It was concluded that to maximize journal coverage and avoid missing potentially relevant evidence, CAB Abstracts should be included in any veterinary literature search.

RESUMO

BACKGROUND: While most cattle and sheep in the United Kingdom are stunned before slaughter, non-stun methods are permitted to supply meat to specific consumers. This study aimed to identify the existing literature that compared animal welfare indicators during stun and non-stun slaughter, using a scoping review framework. METHOD: Following a structured search strategy, including the establishment of a PICO (population, intervention, comparator and outcomes) question, a comprehensive literature search of the CAB Abstracts, MEDLINE and PubMed databases, was conducted. A total of 962 papers were identified, of which 16 were selected for data extraction. RESULTS: Fourteen papers concluded that welfare at slaughter was negatively impacted at non-stun slaughter in comparison to stun slaughter; two papers were inconclusive. Welfare indicators identified included biochemical parameters, brain activity and visual signs of consciousness. Limitations regarding inconsistent restraint method, neck cut position and non-standardised measures of welfare at slaughter are highlighted. CONCLUSIONS: This study provides further evidence that stunning is an effective method to improve the welfare of sheep and cattle at slaughter. Animal welfare advisors, politicians, religious communities and others interested in animal welfare could use the findings to further discuss and establish new dialogues for producing updated guidance on animal welfare at slaughter.

RESUMO

BACKGROUND: Quality improvement (QI) methods are a continuous process of iterative tests to improve the quality of a service or product. Using common language has been linked to the successful implementation of QI in human healthcare. This study aimed to assimilate and achieve consensus on veterinary-specific definitions for terms associated with quality care and QI methods in UK veterinary practice. METHODS: A four-round modified eDelphi process with a panel of 50 UK veterinary practice stakeholders was used to generate consensus. The panel selected or suggested the definition they best felt 'fitted' each term. Consensus was reached if there was >70% agreement, and terms were eliminated if there was <15% selection. RESULTS: Thirty-one panellists completed all three rounds of eDelphi; eight participants completed an optional feedback round. From 14 terms, 10 reached consensus, leaving four unresolved definitions. CONCLUSIONS: A majority of terms reached consensus; 90% were new or amended definitions proposed by panel members. Utilising plain English refined by stakeholders will allow successful implementation of QI in veterinary healthcare. Not all terms achieved consensus, highlighting a need for further research to enable successful integration of QI principles as seen in human healthcare.

RESUMO

Clinical decisions in human and veterinary medicine should be based on the best available evidence. The results of primary research are an important component of that evidence base. Regardless of whether assessing studies for clinical case management, developing clinical practice guidelines, or performing systematic reviews, evidence from primary research should be evaluated for internal validity i.e., whether the results are free from bias (reflect the truth). Three broad approaches to evaluating internal validity are available: evaluating the potential for bias in a body of literature based on the study designs employed (levels of evidence), evaluating whether key study design features associated with the potential for bias were employed (quality assessment), and applying a judgement as to whether design elements of a study were likely to result in biased results given the specific context of the study (risk of bias assessment). The level of evidence framework for assessing internal validity assumes that internal validity can be determined based on the study design alone, and thus makes the strongest assumptions. Risk of bias assessments involve an evaluation of the potential for bias in the context of a specific study, and thus involve the least assumptions about internal validity. Quality assessment sits somewhere between the assumptions of these two. Because risk of bias assessment involves the least assumptions, this approach should be used to assess internal validity where possible. However, risk of bias instruments are not available for all study designs, some clinical questions may be addressed using multiple study designs, and some instruments that include an evaluation of internal validity also include additional components (e.g., evaluation of comprehensiveness of reporting, assessments of feasibility or an evaluation of external validity). Therefore, it may be necessary to embed questions related to risk of bias within existing quality assessment instruments. In this article, we overview the approaches to evaluating internal validity, highlight the current complexities, and propose ideas for approaching assessments of internal validity.

RESUMO

African horse sickness (AHS) is a vector-borne disease transmitted by Culicoides spp., endemic to sub-Saharan Africa. There have been many examples of historic and recent outbreaks in the Middle East, Asia and Europe. However, not much is known about infection dynamics and outbreak potential in these naive populations. In order to better inform a previously published ordinary differential equation model, we performed a systematic literature search to identify studies documenting experimental infection of naive (control) equids in vaccination trials. Data on the time until the onset of viraemia, clinical signs and death after experimental infection of a naive equid and duration of viraemia were extracted. The time to viraemia was 4.6 days and the time to clinical signs was 4.9 days, longer than the previously estimated latent period of 3.7 days. The infectious periods of animals that died/were euthanized or survived were found to be 3.9 and 8.7 days, whereas previous estimations were 4.4 and 6 days, respectively. The case fatality was also found to be higher than previous estimations. The updated parameter values (along with other more recently published estimates from literature) resulted in an increase in the number of host deaths, decrease in the duration of the outbreak and greater prevalence in vectors.

RESUMO

Humans' individual differences including their demographics, personality, attitudes and experiences are often associated with important outcomes for the animals they interact with. This is pertinent to companion animals such as cats and dogs, given their social and emotional importance to humans and degree of integration into human society. However, the mechanistic underpinnings and causal relationships that characterise links between human individual differences and companion animal behaviour and wellbeing are not well understood. In this exploratory investigation, we firstly quantified the underlying structure of, and variation in, human's styles of behaviour during typical human-cat interactions (HCI), focusing on aspects of handling and interaction known to be preferred by cats (i.e. 'best practice'), and their variation. We then explored the potential significance of various human individual differences as predictors of these HCI styles. Seven separate HCI styles were identified via Principal Component Analysis (PCA) from averaged observations for 119 participants, interacting with sociable domestic cats within a rehoming context. Using General Linear Models (GLMs) and an Information Theoretic (IT) approach, we found these HCI PC components were weakly to strongly predicted by factors including cat-ownership history, participant personality (measured via the Big Five Inventory, or BFI), age, work experience with animals and participants' subjective ratings of their cat behaviour knowledge. Paradoxically, greater cat ownership experiences and self-assessed cat knowledge were not positively associated with 'best practice' styles of HCI, but were instead generally predictive of HCI styles known to be less preferred by cats, as was greater participant age and Neuroticism. These findings have important implications regarding the quality of human-companion animal relationships and dyadic compatibility, in addition to the role of educational interventions and their targeting for optimal efficacy. In the context of animal adoption, these results strengthen the (limited) evidence base for decision making associated with cat-adopter screening and matching. In particular, our results suggest that greater cat ownership experiences and self-reports of cat knowledge might not necessarily convey advantages for cats in the context of HCI.

RESUMO

Surgical sterilisation is a core activity of free-roaming dog population management (DPM) programmes globally. However, there is limited published evidence on its impact at the population level. To support evidence-based decision making in this field, it is important that research conducted is relevant to those involved in working with free-roaming dogs and implementing such programmes. The aim of this study was to adapt the James Lind Alliance (JLA) user involvement approach to systematically identify the top 10 research priorities regarding the impact of canine sterilisation. International stakeholders with experience working in DPM were asked in an online survey what unanswered questions they had regarding the impact of sterilisation programmes. Thematic analysis of survey responses was used to develop a long list of collated indicative research questions (CIRQs). A literature review was performed to identify questions that were 'true uncertainties' (had not been answered by evidence review). These questions were reduced to a shortlist via an online interim prioritisation survey, and a Delphi consensus process determined the top 10 priorities. The top 10 questions related to dog population size and turnover, dog bite incidents, rabies control, implementation in the field and human behaviour change. These priorities were identified and shaped by people with direct experience of canine surgical sterilisation programmes, and as such are an essential resource for directing future funding and research. Addressing these priorities will generate evidence that is directly applicable to policy makers and practitioners who make decisions regarding the management of free-roaming dogs (FRDs) worldwide.

RESUMO

Calf morbidity and mortality rates are often high in dairy herds, raising animal welfare concerns and negatively affecting farm economic efficiency and future performance. Disease prevention is critical to maintain calves in good health, but interventions are dependent upon the persons conducting them. This paper explores the perceptions of farmers, farm workers, veterinarians, and other advisors on the management of calfhood disease on dairy farms in England. Participants were recruited using purposive and "snowball" sampling, resulting in 40 in-depth, semi-structured interviews-26 with dairy farmers and 14 with advisors. Interviews were recorded, transcribed, and thematically coded. Three major themes were derived on the basis of interview data: disease occurrence and treatments, management of calf environment, and the role of stockmanship and perceived control. Respiratory and gastrointestinal diseases in calves were those reported to be most problematic on dairy farms. Limited time and financial resources caused some farmers and advisors to experience a perceived inability to control calf health without antimicrobial treatments. Overall, the findings emphasise the importance of human influences on calf health and disease in the context of influencing the interactions among the host, pathogens, and the environment. Further research should investigate what "attention to detail" means within different farm contexts and practices, as this was believed to be important in the promotion of better husbandry standards and health. We recommend the use of supportive knowledge exchange processes, including facilitation, to empower farmers to promote continuous improvement in calf health.
