    | Contributor(s):: Dalmau, A., Nande, A., Vieira-Pinto, M., Zamprogna, S., Martino, G. di, Ribas, J. C. R., Costa, M. P. da, Halinen-Elemo, K., Velarde, A.

    The objective of the present study is to assess the variability of the measures used in the welfare quality (WQ) protocol for pigs among slaughterhouses in five different countries and to propose alarm and critical thresholds for the calculation of scores for future development of an animal...

  3. Human-animal interactions and safety during dairy cattle handling - comparing moving cows to milking and hoof trimming

    | Contributor(s):: Lindahl, C., Pinzke, S., Herlin, A., Keeling, L. J.

    Cattle handling is a dangerous activity on dairy farms, and cows are a major cause of injuries to livestock handlers. Even if dairy cows are generally tranquil and docile, when situations occur that they perceive or remember as aversive, they may become agitated and hazardous to handle. This...

  4. Feasibility of Canine Therapy Among Hospitalized Pre-Heart Transplant Patients

    | Contributor(s):: Snipelisky, D., Duello, K., Gallup, S., Myrick, J., Taylor, V., Yip, D., Dawson, N., Walters, R., Burton, M. C.

  5. Heartworm in Canines: Trends in Rhode Island Shelter Populations

    | Contributor(s):: Kelsey L. McKenna

    Each year thousands of dogs in the United States become infected with heartworm, which is caused by Dirofilaria immitis. D. immitis is a parasite that is transmitted to dogs via a bite by an infected mosquito. Nine of the seventy competent mosquito species reside in Rhode Island. The true...

  6. Puppy temperament assessments predict breed and American Kennel Club group but not adult temperament

    | Contributor(s):: Robinson, L. M., Thompson, R. S., Ha, J. C.

    Puppy assessments for companion dogs have shown mixed long-term reliability. Temperament is cited among the reasons for surrendering dogs to shelters. A puppy temperament test that reliably predicts adult behavior is one potential way to lower the number of dogs given to shelters. This study used...

  7. Behavioural, endocrine and cardiac autonomic responses to a model of startle in horses

    | Contributor(s):: Villas-Boas, J. D., Dias, D. P. M., Trigo, P. I., Almeida, N. A. dos S., Almeida, F. Q. de, Medeiros, M. A. de

    Startle is a fast response elicited by sudden acoustic, tactile or visual stimuli in a variety of animal species and in humans. The magnitude of startle response can be modulated by external and internal variables and can be a useful tool to study the sensory-motor integration in animals....

  8. Pinch-induced behavioural inhibition (clipthesia) as a restraint method for cats during veterinary examinations: preliminary results on cat susceptibility and welfare

    | Contributor(s):: Nuti, V., Cantile, C., Gazzano, A., Sighieri, C., Mariti, C.

    Cats are often subjected to minimally painful or forced procedures during routine clinical practice, which can be poorly tolerated, leading veterinary surgeons to need to offer physical restraint, usually aided by an assistant. The aim of this study was to assess the effectiveness and ultimate...

  9. Predictors of cardiovascular events and mortality in the Systolic Hypertension in the Elderly Program pilot project

    | Contributor(s):: Siegel, D., Kuller, L., Lazarus, N. B., Black, D., Feigal, D., Hughes, G., Schoenberger, J. A., Hulley, S. B.

  10. A trained demonstrator has a calming effect on naive horses when crossing a novel surface

    | Contributor(s):: Rorvang, M. V., Ahrendt, L. P., Christensen, J. W.

    Habituated horses have been found to have a calming effect on conspecifics in fear-eliciting situations. In practice, experienced horses are often used as companions when young horses are introduced to potentially frightening situations, like loading onto a trailer. However, studies of social...

  11. The influence of gentle interactions on avoidance distance towards humans, weight gain and physiological parameters in group-housed dairy calves

    | Contributor(s):: Lurzel, S., Munsch, C., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.

    The quality of the relationship between cattle and their caretakers is important for animal welfare and productivity. Nevertheless, the influence of gentle interactions on group-housed dairy calves has not been thoroughly studied so far. We examined the effects of 42 min of gentle interactions...

  12. Exploring synchronicity in the heart rates of familiar and unfamiliar pairs of horses and humans undertaking an in-hand task

    | Contributor(s):: Hockenhull, J., Young, T. J., Redgate, S. E., Birke, L.

    Physiological responses that occur in horses and humans during their interactions, on the ground and during ridden work, have been investigated in a number of studies with some conflicting results. These suggest that in some situations emotional state may be transferred from humans to horses and...

  13. The psychological and physiological effects of using a therapy dog in mindfulness training

    | Contributor(s):: Henry, C. L., Crowley, S. L.

    The present study was a randomized controlled trial examining the psychological and physiological effects of adding animal-assisted therapy (AAT) to a modified Mindfulness-Based Stress Reduction program (MBSR) for clients experiencing psychological distress. It was hypothesized that AAT would...

  14. Does physical contact with a dog or person affect performance of a working memory task?

    | Contributor(s):: Gee, N. R., Friedmann, E., Coglitore, V., Fisk, A., Stendahl, M.

    Working memory (WM) plays a critical role in the execution of a wide variety of cognitive tasks and predicts academic success. This study was designed to compare the impact of the presence of a dog or a person, and physical contact with them, on the performance of a WM task. It also examined...

  15. Effects of gentle interactions on the relationship with humans and on stress-related parameters in group-housed calves

    | Contributor(s):: Lurzel, S., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.

    Although the relationship between farm animals and humans has strong implications for animal welfare and productivity, there have been few experimental studies on the influence of gentle interactions in group-housed calves. In the present study, Austrian Simmental calves were housed in groups of...

  16. Validating the use of qualitative behavioral assessment as a measure of the welfare of sheep during transport

    | Contributor(s):: Wickham, S. L., Collins, T., Barnes, A. L., Miller, D. W., Beatty, D. T., Stockman, C. A., Blache, D., Wemelsfelder, F., Fleming, P. A.

    We tested the application of qualitative behavioral assessment (QBA) as a welfare assessment tool. Sheep were exposed to road transport treatments, and behavioral expressions were compared between experimental treatments and validated by correlation with physiological measures. We compared...

    | Contributor(s):: Nyman, J.

  18. Are results of Crib Opening Test connected with efficacy of training horses in a round-pen?

    | Contributor(s):: Wilk, I., Kedzierski, W., Stachurska, A., Janczarek, I.

    Training the horse is based on human-horse relationship, which requires that the horse shows active, conscious behaviour as well as an ability to learn. It was hypothesized that the horse's learning skill to open the crib is correlated with the effectiveness of training. The aim of the study was...

  19. Effects of sounds of different quality on the behaviour and heart beat parameters of goats

    | Contributor(s):: Johns, J., Patt, A., Hillmann, E.

    In alpine regions, bells are used to relocate free-ranging grazers like cows and goats. Considering that goats have a well-developed hearing capacity, sounds (e.g. a chime of a bell) may act as stressors depending on their characteristics. The aim of this study was to test whether a non-uniform...

  20. Measuring heart rate variability in horses to investigate the autonomic nervous system activity - pros and cons of different methods

    | Contributor(s):: Stucke, D., Ruse, M. G., Lebelt, D.

    Power spectrum analysis of heart rate variability (HRV) may provide insight into the mental state of the animal held in restricted specific experimental conditions. Determining inter-beat-interval (IBI) variations is one way to measure changes in autonomic nervous system (ANS) activity in horses....
