Human Preferences for Conformation Attributes and Head-And-Neck Positions in Horses
| Contributor(s):: Georgina L. Caspar, Navneet K. Dhand, Paul D. McGreevy
Human preferences for certain morphological attributes among domestic animals may be entirely individual or, more generally, may reflect evolutionary pressures that favor certain conformation. Artificial selection for attributes, such as short heads and crested necks of horses, may have...

Understanding Cows' Emotions on Farm: Are Eye White and Ear Posture Reliable Indicators?
| Contributor(s):: Monica Battini, Anna Agostini, Silvana Mattiello
Understanding the emotions of dairy cows is primarily important in enhancing the level of welfare and provide a better life on farm. This study explored whether eye white and ear posture can reliably contribute to interpret valence and arousal of emotions in dairy cows. The research was...
Tail and ear movements as possible indicators of emotions in pigs
| Contributor(s):: Marcet Rius, Míriam, Pageat, Patrick, Bienboire-Frosini, Cécile, Teruel, Eva, Monneret, Philippe, Leclercq, Julien, Lafont-Lecuelle, Céline, Cozzi, Alessandro
A better understanding of animal emotions is an important goal in disciplines ranging from neuroscience to animal welfare science, but few reliable tools exist for measuring these emotions. Play behaviour is generally recognized as a trigger of positive emotions in mammals, and previous studies...
An unexpected acoustic indicator of positive emotions in horses
out of 5 stars
| Contributor(s):: Mathilde Stomp, Maël Leroux, Marjorie Cellier, Séverine Henry, Alban Lemasson, Martine Hausberger
Indicators of positive emotions are still scarce and many proposed behavioural markers have proven ambiguous. Studies established a link between acoustic signals and emitter’s internal state, but few related to positive emotions and still fewer considered non-vocal sounds. One of them,...

Working Dogs Drinking a Nutrient-Enriched Water Maintain Cooler Body Temperature and Improved Pulse Rate Recovery After Exercise
| Contributor(s):: Brian M. Zanghi, Patrick J. Robbins, Meghan T. Ramos, Cynthia M. Otto
Exercise-related physiological changes were evaluated in hydrated, exercise-conditioned working dogs with free access to tap water (TW) with or without a nutrient-enriched water supplement (NW). Physiological samples and measures were collected before and after work-related field tasks in a...
Evaluating the physical welfare of dogs in commercial breeding facilities in the United States
| Contributor(s):: Moriah J. Hurt, Candace Croney (adviser)
Despite high levels of public concern, the state of commercial breeding (CB) dog welfare is largely unknown. Therefore, this study aimed to characterize the physical welfare of dogs in CB facilities and their environment in Indiana. This study specifically aimed 1) to characterize dog foot...
Welfare effects of a disease eradication programme for dairy goats
| Contributor(s):: Muri, K., Leine, N., Valle, P. S.
The Norwegian dairy goat industry has largely succeeded in controlling caprine arthritis encephalitis (CAE), caseous lymphadenitis (CLA) and paratuberculosis through a voluntary disease eradication programme called Healthier Goats (HG). The aim of this study was to apply an on-farm welfare...

Tail Docking and Ear Cropping Dogs: Public Awareness and Perceptions
| Contributor(s):: Katelyn E. Mills, Jesse Robbins, Marina A. G. von Keyserlingk
Tail docking and ear cropping are two surgical procedures commonly performed on many dog breeds. These procedures are classified as medically unnecessary surgeries whose purpose is primarily cosmetic. Available attitude research surrounding these controversial practices has been limited to...
Dogs' body language relevant to learning achievement
| Contributor(s):: Hasegawa, M., Ohtani, N., Ohta, M.
The facial expressions and body postures of dogs can give helpful information about their moods and emotional states. People can more effectively obedience train their dogs if we can identify the mannerisms associated with learning in dogs. The aim of this study was to clarify the dog's body...
Reactions of sheep towards three sets of emotional stimuli: (in) consistency in respect to stimulus valence and sheep identity
| Contributor(s):: Gygax, L., Vogeli, S.
There is an increasing interest in affective states in applied animal behaviour science, because these states are thought to reflect welfare from the perspective of the animals. Also, it can be expected that individuals differ in how they consistently react to emotional challenges. Recently, we...
The effect of physical contact between dairy cows and calves during separation on their post-separation behavioural response
| Contributor(s):: Johnsen, J. F., Ellingsen, K., Grondahl, A. M., Boe, K. E., Lidfors, L., Mejdell, C. M.
Premature breaking of the maternal bond between a cow and her calf triggers a strong behavioural response which renders separation and weaning major welfare challenges in suckling systems. Fence-line separation and weaning allowing physical contact has been evaluated for beef cattle and is...

Owner perceptions of companion dog expressions of positive emotional states and the contexts in which they occur
| Contributor(s):: Buckland, E. L., Volk, H. A., Burn, C. C., Abeyesinghe, S. M.
Promotion of positive experiences in companion animals is essential for maximising good welfare. However, the dearth of published literature on the experience and expression of positive emotional states in companion dogs suggests they are less well understood than negative emotions. Owner...
Welfare by the ear: comparing relative durations and frequencies of ear postures by using an automated tracking system in sheep
| Contributor(s):: Vogeli, S., Wechsler, B., Gygax, L.
Given the increased interest in animal emotional reactions for assessing welfare, indicators for such reactions are sought. Ear postures and movements have been found to be promising indicators of emotional states in sheep and other animals. The manual recording of ear postures, however, is very...
Vocal recognition of owners by domestic cats ( Felis catus)
| Contributor(s):: Saito, A., Shinozuka, K.
Domestic cats have had a 10,000-year history of cohabitation with humans and seem to have the ability to communicate with humans. However, this has not been widely examined. We studied 20 domestic cats to investigate whether they could recognize their owners by using voices that called out the...
