Evaluating the physical welfare of dogs in commercial breeding facilities in the United States
out of 5 stars
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...
Stocking density affects welfare indicators of growing pigs of different group sizes after regrouping
Contributor(s):: Fu, LingLing, Li, HuiZhi, Liang, TingTing, Zhou, Bo, Chu, QingPo, Schinckel, A. P., Yang, XiaoJing, Zhao, RuQian, Li, PingHua, Huang, RuiHua
In recent years, the concept of animal welfare began to be accepted by the Chinese people. On some intensive pig farms, the stocking density for growing pigs is too great, leading to decreased animal welfare. In order to study the relationships between stocking density and welfare indicators and...
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...
Can ear postures reliably measure the positive emotional state of cows?
Contributor(s):: Proctor, H. S., Carder, G.
Animal welfare science is increasingly concerned with the promotion of positive emotions in animals, yet little is known about how to measure them. We examined whether ear postures in dairy cows were reliable indicators of a low arousal, positive emotional state. We conducted a total of 381, 15...
Fresh wood reduces tail and ear biting and increases exploratory behaviour in finishing pigs
Contributor(s):: Telkanranta, H., Bracke, M. B. M., Valros, A.
Chewing and rooting are high behavioural priorities in pigs. Lack of suitable materials can lead to abnormal behaviours such as tail and ear biting. In commercial farming, slatted floors limit the use of straw, and various point-source objects have therefore been developed. The crucial challenge...
Investigating the motivation to play in lambs
Contributor(s):: Chapagain, D., Uvnas-Moberg, K., Lidfors, L. M.
The aim of this study was to identify behaviours and ear postures linked to the appetitive, consummatory and post-consummatory motivational phases of play in male lambs, and to evaluate how cortisol was affected by play. Ten pairs of male lambs, Ovis aries were observed in a play arena three...
Prevalence and antimicrogram of Staphylococcus intermedius group isolates from veterinary staff, companion animals, and the environment in veterinary hospitals in Korea

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...
Does stocking density modify affective state in pigs as assessed by cognitive bias, behavioural and physiological parameters?
Contributor(s):: Scollo, A., Gottardo, F., Contiero, B., Edwards, S. A.
Recent studies suggest that emotional state can affect cognitive abilities of humans and non-human animals, determining biases in information processing. Negative mental states, such as anxiety or depression, induce pessimistic judgments of ambiguous stimuli. These assumptions may be used to...
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...
