The role of neophobia in a pioneer olfactory enrichment for amazons, macaws, and toucans / El papel de la neofobia en un enriquecimiento olfativo pionero para guacamayos, loros y tucanes

Abstract Introduction: Despite sensory enrichment being critical for ensuring the well-being of captive wild animals, smells are not being included in enrichment protocols for birds. For this group, neophobia can be a problem when it comes to implementing new enrichment devices. Objective: To explore how participation in an olfactory enrichment and latency times varies between bird taxonomic groups (Amazona spp. / Ara spp. / Ramphastos spp.). Methods: We exposed 257 birds to a scent enrichment, and we recorded which individuals engaged with it and the time they took to interact with it. Results: We discovered that participation by toucans in the enrichment was higher compared to amazons and macaws. Furthermore, latency time to interact with the enrichment was higher in amazons that in the other species. Our findings could suggest that toucans are neophilic species which could benefit from higher exploration rates. Amazons on the contrary seem to be particularly neophobic, possibly because of their less opportunistic feeding habits compared to toucans and their higher vulnerability to predation compared to macaws. Conclusion: These results point out that toucans would be more inclined to engage in environmental enrichments, while a more natural design using smells inside familiar objects could be a more successful enrichment for psittacids.

Resumen Introducción: A pesar de que el enriquecimiento sensorial es fundamental para garantizar el bienestar de los animales silvestres en cautiverio, los olores no son incluidos de forma rutinaria en los protocolos de enriquecimiento para aves. Además, en el caso de estos animales, la neofobia puede ser un problema a la hora de implementar nuevos dispositivos de enriquecimiento. Objetivo: Explorar cómo varía la participación y la latencia en la interacción con un enriquecimiento olfativo entre grupos taxonómicos de aves (Amazona spp. / Ara spp. / Ramphastos spp.). Métodos: Expusimos a 257 aves a un enriquecimiento olfativo y registramos qué individuos participaron y el tiempo que tardaron en interactuar con él. Resultados: La participación en el enriquecimiento fue mayor en los tucanes en comparación con las amazonas y los guacamayos. Además, el tiempo de latencia para interactuar con el enriquecimiento fue mayor en las amazonas que en las otras especies. Nuestros hallazgos sugieren que los tucanes son especies neofílicas que podrían beneficiarse de tasas de exploración más altas. Por otro lado, las amazonas parecen ser particularmente neofóbicas, posiblemente debido a sus hábitos alimenticios menos oportunistas en comparación con los tucanes y a su mayor vulnerabilidad a la depredación en comparación con los guacamayos. Conclusión: Estos resultados señalan que los tucanes serían más proclives a participar en enriquecimientos ambientales, mientras que un diseño que utilice olores dentro de objetos más naturales o familiares podría ser más exitoso para las psitácidas.

The cage-free egg sector: perspectives of Indian poultry producers.

India is ranked as the 2nd largest egg producer in the world. Despite the prevalence of backyard poultry (free range), a majority of the commercial egg-laying hens in the country are still housed in battery cages. There is a global shift toward cage-free eggs, due to regulations and increased demand from conscious consumers and food corporations. However, there are very few commercial cage-free facilities in India to meet this demand. The aim of this study was to undertake a needs-assessment survey of Indian egg producers on cage-free production, and understand what support is needed to build the capacities of the cage-free egg production sector to develop it into a viable and sustainable alternative to battery cage eggs. The results showed that nearly all producers agreed on the need for additional support in shifting to, and operating in, the cage-free sector. This included support in the form of financial assistance, technical training, and promotion of the cage-free sector. The results of this study highlight the pressing need for government and private support, in the absence of which cage-free producers are compelled to compete with battery cage poultry producers on prices, which will result in increased losses and failure of the sector, since they have not yet achieved economies of scale.

Enhancing the Horse Grimace Scale (HGS): Proposed updates and anatomical descriptors for pain assessment.

The use of grimace scales enables the clinical identification of changes in the facial expressions of animals caused by pain. The Horse Grimace Scale (HGS) is one such tool, comprising a pain coding system based on facial expressions and assessing six Facial Action Units (FAUs). Each FAU is accompanied by descriptions and anatomical details to assist the evaluator. However, the morphological descriptions for certain FAUs in the HGS are not sufficiently detailed, potentially hindering accurate interpretation. This study is an analytical investigation aimed at enhancing the morphoanatomical details in the HGS and providing raters with more comprehensive materials for pain evaluation in horses using this scale. To achieve this, detailed anatomical analyses were conducted using established references in veterinary anatomy. Initially, we propose substituting the term 'ear' with 'auricle' or 'pinna' and replacing 'area above the eye' with 'supraorbital region' for anatomical accuracy. Additionally, we introduce detailed morphoanatomical descriptions that identify specific landmarks, with the goal of ensuring more consistent application of the HGS and reducing interpretation variability. Furthermore, this study provides an explanation of the muscles involved in the investigated FAUs. These adjustments on the descriptions and evaluations remain unverified, however it is anticipated that the descriptive enhancements lead us to understand that higher interobserver reliability can be achieved for each of the FAUs.

Mule trains to mountain roads: the role of working mules in supporting resilient communities in the Himalayas.

Working equids play a central role in mountainous communities, but their work often goes unnoticed by the wider world, with sparse documentation of their role, value, or welfare - a state which often extends to their human counterparts. Communities living in the remote Manaslu Valley, Nepal, face a number of uncertainties, including extreme weather events due to the seasonal monsoon and, more recently, the construction of a new road network. Using semi-structured interviews, questionnaires, and Equine Assessment Research and Scoping (EARS) welfare assessments, we outline the specific role of pack mules in supporting the lives of local people, explain the nuanced links between human experience and mule welfare, and gain insight into how people living in this volatile environment manage uncertainty and risk. Mule work was felt to be the 'only option' for a sustainable livelihood for most mule owners although, in some cases, mules had enabled respondents to diversify their income. Mule owners with more husbandry experience did not own mules in more positive behavioural states, which may suggest a lack of generational knowledge and support networks. Short-term ongoing risks, such as the monsoon or unstable tracks, had a larger impact both financially and emotionally than the long-term but distant implications of the road construction. Mule owners must constantly balance the risk of working during the monsoon season, when conditions are treacherous but pay was higher, with losing valuable income but keeping themselves and their mules safe; they do, however, have a more mobile option for employment than non-owners. Mules enable a level of resilience and agility for communities living with constant uncertainty and change, which is only beginning to be recognised formally within the sustainable development sphere. Integration of animal welfare into the SDGs would allow humanitarian aid initiatives to strengthen support networks around working equids, which would greatly benefit the mules and humans alike.

Animal welfare during transport, evolution, and perspectives of European Union Legislation and Policy.

In the one health approach, which summarizes the concept that human, animal, and plant health are interdependent and linked to the ecosystems in which they exist, animal welfare assumes an important role. In addition, the Farm to Fork Strategy of the European Union recognizes animal welfare as an essential component. Transport of animals involves a number of issues related to welfare. Animals are subjected to continuous stress, not only during transit on vehicles, vessels, trains, or airplanes, but also during loading and unloading operations. The handling and transport conditions have improved from basic and relatively rudimentary systems, with elements to attenuate the discomfort of animals having been gradually introduced, especially for long-distance transport. Despite several improvements in animal welfare standards during transportation there are still pressing issues in current EU legislation which deserve reviewing. Recently, several scientific opinions on animal welfare, including during transport, have been published by the European Food Safety Agency, following requests by the European Commission. In addition, the European Court of Auditors published its last report focused on animal welfare during transport. These reports underline the need to review current legislation governing the topic and highlight a number of outstanding issues in the European Union and in Third Countries. This article summarizes the history and current status of this complex issue.

Effects of intermittent lighting program and light colour on ocular health variables as welfare indicators in broiler chickens.

1. The objective of the present study was to examine the effect of lighting programs and light colour on ocular health variables as welfare indicators in Ross 308 broilers.2. A total of 384, male, one-d-old broiler chickens (Ross 308) were placed in a completely randomised design with a 2 × 2 factorial arrangement of lighting program (continuous or intermittent) and light colour (white and green LED light). Ross 308 broilers under restricted lighting had 18 h of light (18 L:6D), while those under intermittent lighting had cycles of 17 L:3D:1 L:3D throughout the experimental period, which lasted 42 d.3. At the end of the experiment, all eyes of birds (n = 96 birds) underwent a complete ophthalmic examination, which included the Schirmer tear test I, intraocular pressure and eye dimensions. In addition, 32 broilers (eight birds per trial groups) aged 42 d underwent ophthalmic examination to include assessment of ocular ultrasound biometry.4. Light colour had a significant influence on the mean intraocular pressure (p < 0.001). The Ross 308 broilers kept with intermittent lighting had lower eye weights (2.29 g; p < 0.05), palpebral fissure length (14.39 mm; p < 0.01), eye dorsoventral diameter (17.46 mm; p < 0.05), anteroposterior size (13.70 mm; p < 0.01) and corneal dorsoventral diameter (7.81 mm; p < 0.05) compared to those reared under restricted lighting.5. In conclusion, these values for Ross 308 broilers may be applied in poultry ophthalmology to detect early eye disease symptoms and to help the diagnosis of tear disorders that could cause economic losses and welfare issues. Intermittent lighting and green LED light may help reduce eye health problems thus contributing to improved welfare in broilers.

Overview of the various methods used to assess walking ability in broiler chickens.

BACKGROUND: Walking ability is a highly important animal-based indicator of welfare in broilers that warrants monitoring across commercial production. METHODS: A review of the technical and scientific literature on existing methods for assessing walking ability in broilers was conducted, and the reliability, validity and feasibility of the different methods were assessed when relevant information was available. RESULTS: Visual gait scoring has high validity, minimal equipment needs and is relatively quick to perform; however, this method is subjective and requires extensive training. Due to this, more objective tests, such as the latency to lie test, have been developed, although more validation of these tests is required. Other identified methods, such as obstacle courses, the rotarod test and kinetic and kinematic approaches, require considerable amounts of equipment, making them impractical for use during on-farm inspections. Automated methods that rely on movement or activity data have potential for future development but currently lack the resolution of traditional gait scoring and require equipment such as cameras or accelerometers. CONCLUSIONS: Objective, seemingly valid, repeatable and feasible options exist for the assessment of walking ability that would facilitate the monitoring of commercial broiler welfare; however, more validation of these methods is required, especially in commercial farm settings.

Online collaborative research on seasonal work. Collective capabilities to resist on precarious work and living conditions.

BACKGROUND: The number of seasonal workers in the agricultural sector in France is increasing and their working conditions are difficult and disgraceful. While they have been shown in various studies to be subject to processes that result in them being unable to act on occupational health, some of them, mobilized online, have formed a collective whose is permitted them to develop collective actions. OBJECTIVES: Our article aims to describe this online collective and how the power to act emerged from the discussions. The purpose it's also to determine how the functioning of these groups fosters the expression of a collective point of view and the achievement of goals that is not attained elsewhere. METHODS: We carried out a collaborative research online with a collective of seasonal workers, which consisted in following and taking part in discussions about conditions at work and outside of work, using an instant messaging tool. The results of this collaborative research, included testimonies registration and co-produced with seasonal workers, has been analyzed mobilizing A. Sen's capabilities approach. RESULTS: During their online discussions, the seasonal workers allow themselves to share the situations of injustice they are subject to with the other members. Here, we present their output and collective actions which were made possible by the mobilization of the resources of some of their members or by collaborating with other actors. CONCLUSIONS: In spite of the remarkable conversion factors made available through this collective action online, certain "failures" show that in order for these workers to have better access to their rights, effective support by public policy is indispensable.

Objective assessment of chronic pain in donkeys using the Donkey Chronic Pain Scale.

OBJECTIVE: To clinically evaluate previously developed pain scales [Donkey Chronic Pain Composite Pain Scale (DCP-CPS), Donkey Chronic Pain Facial Assessment of Pain (DCP-FAP) and combined Donkey Chronic Pain Scale (DCPS)], including behavioural and facial expression-based variables, for the assessment of chronic pain in donkeys. STUDY DESIGN: Prospective, blinded clinical study. ANIMAL: A group of 77 donkeys (34 patients and 43 healthy control animals). METHODS: Animals were assessed by two observers that were blinded to the condition of the animals. RESULTS: Both DCP-CPS and DCP-FAP, and resulting combined DCPS scores, showed good interobserver reliability [intraclass correlation coefficient (ICC) = 0.91, 95% confidence interval (CI) = 0.86-0.95, p < 0.001; ICC = 0.71, CI = 0.50-0.83, p < 0.001 and ICC = 0.84, CI = 0.72-0.91, p < 0.001, respectively]. All scores (DCP-CPS, DCP-FAP and the resulting combined DCPS) were significantly higher for patients than for controls at all time points (p < 0.001 for all three scales). Sensitivity and specificity for identification of pain (cut-off value >3) was 73.0% and 65.1% for DCP-CPS, and 60.9% and 83.3% for DCP-FAP, respectively. For the combined DCPS, sensitivity was 87.0% and specificity 90.9% (cut-off value >6). CONCLUSIONS AND CLINICAL RELEVANCE: Based on behavioural and facial expression-based variables, DCPS proved a promising and reproducible tool to assess different types of chronic pain in donkeys. The combination of behavioural and facial expression-based variables showed the best discriminatory characteristics in the current study. Further studies are needed for refinement of these tools.

Socioeconomic benefits associated with bats.

BACKGROUND: While bats are tremendously important to global ecosystems, they have been and continue to be threatened by loss of habitat, food, or roosts, pollution, bat diseases, hunting and killing. Some bat species have also been implicated in the transmission of infectious disease agents to humans. While One Health efforts have been ramped up recently to educate and protect human and bat health, such initiatives have been limited by lack of adequate data on the pathways to ensure their support. For instance, data on the role of bats in supporting different components of human welfare assets would be utilized as a stepping stone to champion conservation campaigns. Unfortunately, these data are limited and efforts to synthesize existing literature have majorly focused on few components human welfare leaving other important aspects. METHODS: Here, we analyze benefits associated with bats in the context of welfare economics considering all the asset components. We surveyed scientific and gray literature platforms utilizing particular keywords. We then classified these values using integrated approaches to understand different values across human welfare assets of "health," "material and immaterial assets," "security or safety" and "social or cultural or spiritual relations". RESULTS: We found 235 papers from different countries indicating that bats play fundamental roles in supporting human welfare. These benefits were more prevalent in Asia and Africa. In terms of the use of bats to support welfare assets, bats were majorly utilized to derive material and immaterial benefits (n = 115), e.g., food and income. This was followed by their use in addressing health challenges (n = 99), e.g., treatment of ailments. There was a similarity in the benefits across different regions and countries. CONCLUSION: These results indicate potential opportunities for strengthening bat conservation programs. We recommend more primary studies to enhance understanding of these benefits as well as their effectiveness in deriving the perceived outcomes.

Assessing the Health and Welfare Benefits of Interventions Using the Wider Societal Impacts Framework.

OBJECTIVES: Health technology assessment bodies advocate capturing the value of interventions in terms of their benefits to health and broader welfare. The wider societal impacts (WSI) framework considers how changes in health alter a person's net contribution to society-that is, what they produce minus what they consume. In this research, we review this framework and explore the scope to differentiate WSI by equity-relevant sociodemographic characteristics. METHODS: This research updates previous calculations using publicly available data from population-based surveys in the United Kingdom. We then estimate for 199 chronic conditions: (1) WSI for the average person with the condition and (2) gain in WSI for an improvement of 0.1 in health-related quality of life score. RESULTS: The nature and availability of information varied across population-based surveys and precluded analyses to examine WSI by population subgroup. Our updated estimates mirrored earlier findings that consideration of the broader societal impacts of health would reprioritize interventions compared with assessment on health alone. For example, for the same improvement in health, a woman experiencing diseases of the circulatory system has the highest potential gain in WSI (£354/month) whereas a man experiencing HIV has the lowest potential gain (£233/month). CONCLUSIONS: The WSI framework provides a simple, indirect method to inform resource allocation decisions. Understanding the equity implications of this approach was hindered by differences in the information collected across population-based surveys. Findings demonstrate the potential reprioritization that may occur if the broader welfare benefits of health interventions were used to inform coverage decisions.

Effects of pre-heating of broiler breeder's eggs on hatchability, chick quality, overall performance, and welfare traits in broilers.

This study aimed to investigate the effects of varying pre-heating practices (12-h: PH12; 8-h: PH8; 4-h: PH4 and 0-h or no pre-heating: PH0) of broiler breeder's eggs prior to incubation on hatching, chick quality, overall performance, and welfare traits in broilers. A total of 960 eggs obtained from Ross 308 breeders at 45 weeks were used for pre-heating manipulations and 480 chicks for broiler experiment. Apparent fertility was higher in PH0 (94.6%) and PH4 (94.5%) treatments than in PH8 (91.6%) and PH12 (90.6%); hatchability of fertile and set eggs was higher in PH4 and PH12. PH4, PH8, and PH12 treatments significantly accelerated the average hatching time compared to PH0. General chick quality was not affected by pre-heating treatments. However, chick length was significantly lower in PH0 chicks than PH12. Pre-heating manipulations did not change the overall broiler performance. Welfare characteristics were similar among treatments, while only hock burn was better in PH8 broilers. In conclusion, pre-heating of broiler breeder eggs for 4 to 12 h improved hatching success by lowering embryonic mortality and shortened the average hatching time compared to no pre-heating, and did not cause any significant alteration in chick quality, overall performance, and welfare characteristics.

Closing the Gap: Foster Parents' Lived Experiences and Recommendations for Interdisciplinary Health-Care Providers.

Purpose: This study explored barriers and facilitators to utilizing health-care services for foster youth, from the perspective of foster parents. Background: There are nearly 437,283 youths in the United States foster care system. Youths living in locations that are different from their familial home situations have a significantly higher occurrence of physical and mental health illnesses than children who remain in their familial homes, increasing risk for homelessness, substance use and abuse, chronic long-term illnesses, and incarceration, thus placing additional burden on the health-care system. Design and Methods: This study utilized a qualitative descriptive design with purposive sampling, with video focus groups to explore 15 foster parents' experiences in accessing health-care services for foster youth. Results: Barriers and facilitators to accessing health care and care coordination were identified, including logistics, transportation, electronic health record access, location of health care, and the impact of the social worker. Practice Implications: Nurses are well-positioned to aid in closing gaps in care for foster youth. Conclusions: These experiences provide important insights and implications for health-care providers and for future research and policy development.

US cat caregivers' attitudes on veterinary video telemedicine.

OBJECTIVES: Many cats do not see a veterinarian on an annual basis, and their caregivers face many barriers to accessing veterinary care. A potential solution to overcome some of these barriers is video telemedicine. Thus, the aim of this study was to understand companion cat caregivers' perceptions of using veterinary video telemedicine with their cats. METHODS: An online quantitative questionnaire was used to survey US cat caregivers on their experiences of and attitudes to using video telemedicine with their cats. Participants were required to reside in the USA, be the primary caregiver of at least one cat and be aged 18 years or older. RESULTS: The majority (97.3%) of the 1254 respondents indicated they had never used a video telemedicine appointment with their cat(s) before; however, most (85.7%) indicated they were very or somewhat interested in using video telemedicine with their cat. Overall, caregivers perceived video telemedicine visits as less stressful for themselves (P <0.0002) and their cats (P <0.0001), and as increasing their access to veterinary care (P <0.0001) compared with in-clinic visits. Participants also indicated they would prefer a video telemedicine appointment over an in-clinic appointment for most cat behavioral concerns but preferred in-clinic appointments for most health concerns. Most respondents (51.3%) indicated they would be willing to pay a little less for a telemedicine appointment than an in-clinic visit. CONCLUSIONS AND RELEVANCE: Cat caregivers represent an important population that could benefit from the implementation of video telemedicine into veterinary care. Our results suggest many US cat caregivers indicate an interest and willingness to pay for video telemedicine visits to increase their access to veterinary care and reduce stress associated with veterinary visits for both themselves and their cats. Caregivers showed more interest in using video telemedicine for behavioral concerns than health concerns.

Dr Catherine Chisholm, 'children's physician': Her work for child welfare and feminist networking in Manchester.

Catherine Chisholm BA MB ChB MD FRCP CBE (1879-1952) is celebrated as the first woman to qualify in medicine from Manchester University in 1904 and is remembered for founding the Manchester Babies Hospital in 1914 (later renamed in 1935 as the Duchess of York Hospital for Babies). She was indefatigable in her pursuit to improve the education and status of women doctors; the first woman member and president of the British Paediatric Society; first woman president of the Manchester Medical Society and was mainly responsible for establishing the Medical Women's Federation in 1917. Her career was a complex mixture of medical and social networks that linked her work as a children's physician to the Manchester Public Health Committee, Liberal politics and feminist groups. These networks played an important role in Dr Chisholm's successful career and are at the centre of this paper.

Facility design and management. Strategies for high level biocontainment.

UK Health Security Agency is required to investigate the pathogenesis of emerging or re-emerging infections and to test novel interventions, such as vaccines and therapeutics against these and other diseases, such as tuberculosis and Ebola, that have a significant impact on human health world-wide. Research into the causative agents (mainly BSL 3 and 4) using a wide range of animal species as pre-clinical models brings a number of challenges in terms of effective biocontainment to address human safety whilst optimising delivery of scientific objectives and the welfare of the animals. Here we describe the strategies used for high containment of species that include mice, ferrets, hamsters, rabbits and macaques that have been infected with high consequence pathogens. To ensure relevance of these models we frequently challenge by the aerosol route and monitor the development of disease and protective or therapeutic efficacy by methodologies similar to those used in the clinic. We have devised methods of sampling that can inform on pathogenesis and immune function that include lung lavage and medical imaging such as computed tomography and positron emission tomography-computed tomography. Imaging assists our assessment of progression to disease whilst providing refinement in application of early humane endpoints. We have developed directional flow containment systems that provide quantifiable operator protection whilst allowing group housing and a wide range of enrichment strategies appropriate for each species. Furthermore, we have demonstrated our improvements in animal welfare through use of a software-based Animal Welfare Assessment Grid that was developed with help of NC3Rs funding and enables us to quantify the lifetime experience of animals.

Parasympathetic tone activity, heart rate, and grimace scale in conscious horses of 3 breeds before, during, and after nociceptive mechanical stimulation.

BACKGROUND: Parasympathetic tone activity (PTA) in response to nociceptive stimulus in conscious non-sedated horses is unknown. OBJECTIVES: Study PTA, heart rate (HR), and horse grimace scale (HGS) at rest and during mechanical nociceptive stimulation. ANIMALS: Ninety healthy young adult horses (females, males): 30 each of Friesians, Quarter Horses, and Warmbloods. METHODS: Prospective control study. The study consisted of habituation to equipment (Day 1), baseline recordings (Days 2 and 3), and nociceptive testing applying mild pressure to the metacarpus (Day 4). Parasympathetic tone, HR, and HGS were recorded simultaneously on Days 2 to 4. Each study lasted 30 minutes and was done in triplicate at 3 different time points per day. RESULTS: Baseline PTA was not different among breeds. It decreased in Warmbloods and Quarter Horses during placement of the stimulus device without stimulation (P < .01). A significant decrease in PTA (P < .001) occurred during nociceptive stimulus (marked in Quarter Horses, intermediate in Warmbloods, and mild in Friesians). Heart rate and HGS increased significantly (P < .001) during the stimulus in all breeds but returned to baseline poststimulation. Friesians required higher pressure (P < .05) to elicit an aversive response to the stimulus. CONCLUSIONS: Horses' PTA, HR, and HGS change in response to a mild mechanical nociceptive stimulus with Friesians showing less variation. Stress induced a decrease in PTA in Quarter Horses and Warmbloods but not in Friesians. Friesians appeared to be more tolerant to pain based on PTA, HR, and HGS findings compared with other breeds.

Trauma-informed care beliefs scale-comprehensive for child welfare carers using Rasch analysis.

BACKGROUND: The literature on trauma-informed care practices (TIC) indicates that this framework is beneficial for young people, carers, and staff. However, a significant gap in the literature and practice is the absence of psychometrically sound scales to measure carer adherence to TIC principles. Emerging evidence suggests that TIC practices shift carer attitudes and beliefs, which mediate positive outcomes for both carers and young people. OBJECTIVE: To develop a theoretically comprehensive and psychometrically sound measure of carer TIC beliefs using Rasch methodology. PARTICIPANTS AND SETTING: Active carers (N = 719, M = 43 years, SD = 10.7 years) from online support groups in Australia, Canada, the United States of America, the United Kingdom, and the Republic of Ireland completed the questionnaire online. METHODS: Based on previous research (e.g., limitations of the Trauma-Informed Belief Scale-Brief [TIBS-B]; Beehag, Dryer, et al., 2023a) and a scoping review of the TIC literature (Beehag, 2023), 61 candidate items were created that covered the three main characteristics of carer-related TIC theory (i.e., beliefs on TIC strategies to manage trauma symptoms, beliefs on the impact of adverse childhood experiences (ACE), and beliefs on the importance of self-care/reflection). The resulting data was subjected to Rasch analyses. RESULTS: Following analyses and minor modifications, a 35-item version of the questionnaire was confirmed, which fitted the Rasch model and demonstrated unidimensionality, reasonable targeting, and sound internal consistency reliability (Person Separation Index = 0.81). CONCLUSIONS: The TIBS-C is a psychometrically sound measure of child welfare carer TIC beliefs. Future studies are needed to provide further evidence of its validity (e.g., predictive validity), reliability (e.g., test-retest reliability) and clinical utility.

Impacts of access to legume- or grass-based pasture on behaviour, physiological responses and bacterial load of laying hens.

Despite the plethora of studies on the impacts of access to runs on chickens, there is a paucity of information on the welfare and behavioural repertoire of hens raised in the deep litter houses with or without access to legume- or grass-based pasture. Therefore, this study aimed to evaluate the impact of access to grass or legume pastures by laying hens on behaviour, physiological responses and bacterial load. The study was conducted to evaluate the influence of exposure of egg-type chickens to runs on grass or legume pastures on their welfare and behaviours. The study involved the use of 240 ISA brown pullets from 12 weeks of age and and lasted for 48 weeks. The treatments were deep litter housing with grass-based pasture run (PG), deep litter housing with legume-based pasture run (PL) and deep litter housing without runs (LD) having 80 pullets with four replicates of twenty birds each. Behavioural observations of the hens in each pen were made at 52 weeks of age and tonic immobility was assessed by making the birds lie on their back with their head resting in a U-shaped wooden cradle. The measurements of the respiratory rate and rectal temperature of the hens were assessed at 1:00 p.m. at different laying phases. The gastrointestinal and egg bacterial counts were conducted at 60 weeks of age. Results revealed that the proportion of time spent eating was highest (p < 0.05) in the deep litter housing system, while the legume and grass pasture were similar. The hens spent most of their time standing and eating in the three treatments. However, the time spent standing in PL and PG was similar but significantly higher (p < 0.05) than in LD. Results on tonic immobility duration showed that the time spent by the hens in LD during the reaction was significantly longer than those of the PL and PG in the first, second and third phases of the experiments. However, the time spent by the hens in PL and PG was similar. The rectal temperatures of PL and PG birds were comparable and higher than those of LD during the second phase. On the other hand, there was no difference in the respiratory rate. Plasma triiodothyronine (T3) of the hens did not follow a consistent pattern. The bacterial count in the large intestine in LD and PL was similar but significantly (P < 0.05) higher than that of the PG. It was concluded that access to pasture influenced the behaviours of hens and that tonic immobility duration was shorter in the hens on the pasture, suggesting that access to pasture favoured hens' welfare.
