Using the incidence and impact of health conditions in guide dogs to investigate healthy ageing in working dogs
| Contributor(s):: Caron-Lormier, G., England, G. C. W., Green, M. J., Asher, L.
This study aimed to use retirement data from working guide dogs to investigate healthy ageing in dogs and the demographic factors that influence ageing. Using a dataset of 7686 dogs spanning 20 years, dogs withdrawn for health reasons before they reached retirement were identified. Cases of...
Aspects of juvenile and adolescent environment predict aggression and fear in 12-month-old guide dogs
| Contributor(s):: Serpell, J. A., Duffy, D. L.
Maturational changes in behavior, and the possible influence of the puppy-raising environment on behavioral development, were investigated in a total sample of 978 prospective guide dogs belonging to four different breeds/crosses. All dogs belonged to the same guide dog organization, and had...
Protein expression and genetic variability of canine Can f 1 in golden and Labrador retriever service dogs
| Contributor(s):: Breitenbuecher, C., Belanger, J. M., Levy, K., Mundell, P., Fates, V., Gershony, L., Famula, T. R., Oberbauer, A. M.
Background: Valued for trainability in diverse tasks, dogs are the primary service animal used to assist individuals with disabilities. Despite their utility, many people in need of service dogs are sensitive to the primary dog allergen, Can f 1, encoded by the Lipocalin 1 gene (LCN1). Several...
Identification and development of measures suitable as potential breeding traits regarding dairy cows' reactivity towards humans
| Contributor(s):: Ebinghaus, A., Ivemeyer, S., Rupp, J., Knierim, U.
Behavioural indicators of the human-animal relationship (HAR) are predominantly used in animal welfare science. However, the reactivity of dairy cows - as part of the HAR - is also of interest in the context of dairy breeding, due to its estimated moderate heritability. The avoidance distance...

Fine dogs the project
| Contributor(s):: Laura Catalina Perilla Suarez
For years, the human animal has called the dog as man's best friend, but what does this honestly refer to? What is the relation of the human animal to the dog? How many years ago did the call begin, domestication? , In my project I will solve these questions, in addition to entering the field...
Selection of Breeding Stock among Australian Purebred Dog Breeders, with Particular Emphasis on the Dam
| Contributor(s):: Veronika Czerwinski, Michelle McArthur, Bradley Smith, Philip Hynd, Susan Hazel
Every year, thousands of purebred domestic dogs are bred by registered dog breeders. Yet, little is known about the rearing environment of these dogs, or the attitudes and priorities surrounding breeding practices of these dog breeders. The objective of this study was to explore some of the...
Humans act against the natural process of breeder selection: A modern sickness for animal populations?
| Contributor(s):: Javier Balbontin, Vincenzo Penteriani, Miguel Ferrer
We present a new idea about the possible effects of human-induced mortality on different age cohorts (i.e., breeders vs. juveniles) in long-lived animals. Our hypothesis is based on Curio's idea on the effect of natural selective processes on cohorts to explain age-related increases in...
Transgenic Animals: Their Benefits to Human Welfare
| Contributor(s):: Endang Tri Margawati
Nowadays, breakthroughs in molecular biology are happening at an unprecedented rate. One of them is the ability to engineer transgenic animals, i.e., animals that carry genes from other species. The technology has already produced transgenic animals such as mice, rats, rabbits, pigs, sheep, and...

Acoustic analysis of cattle ( Bos taurus) mother-offspring contact calls from a source-filter theory perspective
| Contributor(s):: Torre, M. P. de la, Briefer, E. F., Reader, T., McElligott, A. G.
Cattle vocalisations have been proposed as potential indicators of animal welfare. However, very few studies have investigated the acoustic structure and information encoded in these vocalisations using advanced analysis techniques. Vocalisations play key roles in a wide range of communication...
An initial investigation into the effects of isolation and enrichment on the welfare of laboratory pigs housed in the PigTurn system, assessed using tear staining, behaviour, physiology and haematology
| Contributor(s):: DeBoer, S. P., Garner, J. P., McCain, R. R., Lay, D. C., Jr., Eicher, S. D., Marchant-Forde, J. N.
In some parts of the world, the laboratory pig ( Sus scrofa) is often housed in individual, sterile housing which may impose stress. Our objectives were to determine the effects of isolation and enrichment on pigs housed within the PigTurn - a novel penning system with automated blood sampling -...
Are farmed salmon more prone to risk than wild salmon? Susceptibility of juvenile farm, hybrid and wild Atlantic salmon Salmo salar L. to an artificial predator
| Contributor(s):: Solberg, M. F., Zhang, ZhiWei, Glover, K. A.
Offspring of farmed Atlantic salmon have been documented to display lower survival than the offspring of wild salmon in the wild. It has been suggested that reduced survival of farmed salmon offspring in the wild could, in part, be explained by increased susceptibility to predation through...
Behavioural reactivity of ewes and lambs during partial and total social isolation
| Contributor(s):: Barnard, S., Matthews, L. R., Messori, S., Vulpiani, M. P., Ferri, N.
This work investigated the differences in the reactivity of Sarda (primiparous n=18, multiparous n=17) and Dorset (multiparous n=8) breeds of sheep and their singleton lambs to two challenging test situations involving a mother-lamb partial separation test and an isolation test. Non-parametric...
Effects of growth-promoting technology on feedlot cattle behavior in the 21 days before slaughter
| Contributor(s):: Stackhouse-Lawson, K. R., Tucker, C. B., Calvo-Lorenzo, M. S., Mitloehner, F. M.
There is growing interest in the animal welfare implications of growth-promoting technology used in feedlot cattle, namely hormonal implants, ionophores, antibiotics and β 2-adrenergic agonists. Previous studies have focused on the effects of implants on aggression, but little work has...
Effects of prepartum housing environment on abnormal behaviour, the farrowing process, and interactions with circulating oxytocin in sows
| Contributor(s):: Yun, JinHyeon, Swan, K. M., Oliviero, C., Peltoniemi, O., Valros, A.
We evaluated the effects on sows of prepartum housing environment on bar-biting (BB) behaviour prior to parturition, farrowing duration from first to tenth piglets, litter size, and circulating oxytocin (OT) concentrations during birth of the first five piglets. A total of 35 sows, approximately...
The power of automated behavioural homecage technologies in characterizing disease progression in laboratory mice: a review
| Contributor(s):: Richardson, C. A.
Behavioural changes that occur as animals become sick have been characterized in a number of species and include the less frequent occurrence of 'luxury behaviours' such as playing, grooming and socialization. 'Sickness behaviours' or behavioural changes following exposure to infectious agents,...
Young Blond d'Aquitaine, Angus and Limousin bulls differ in emotional reactivity: relationships with animal traits, stress reactions at slaughter and post-mortem muscle metabolism
| Contributor(s):: Bourguet, C., Deiss, V., Boissy, A., Terlouw, E. M. C.
The present study investigated relationships between reactivity during tests, stress reactions at slaughter and animal traits in young Blond d'Aquitaine (BA), Limousin (LI) and Angus (AN) bulls. Behavioural and physiological reactivity of animals was evaluated during rearing using a "Human test"...
