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 and physiological responses of domestic dogs ( Canis familiaris) to agonistic growls from conspecifics
Contributor(s):: Wood, P. A., Bie, J. de, Clarke, J. A.
Motivation-structural rule theory predicts that a sender producing harsh, low frequency sounds directed at a conspecific modifies the receiver's behaviour, in part, by communicating its willingness to escalate to an attack. Motivation-structural (MS) rules generally assume that receivers respond...
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...
Comparison of the effects of weaning and castration when conducted separately or in combination on the behaviour of crossbred beef cattle
Contributor(s):: Lambertz, C., Farke-Rover, A., Moors, E., Gauly, M.
The objective of the present study was to evaluate the behavioural effects of Burdizzo castration of crossbred beef calves when weaned and castrated separately (castrated 8 weeks after weaning) or in combination. Over two consecutive years a total of 111 Limousin * Simmental male calves were...
Drinking behaviour in sows kept outdoors during the winter months
Contributor(s):: Andersen, H. M. L., Pedersen, L. J.
In the light of the EU regulation, "pigs must have permanent access to a sufficient quantity of fresh water" and the practical problems it provides farmers during winter to keep water free of ice, the aim of this study was to investigate the influence of periods with frost on the diurnal pattern...
Effect of pre-partum habituation to milking routine on behaviour and lactation performance of buffalo heifers
Contributor(s):: Polikarpus, A., Napolitano, F., Grasso, F., Palo, R. di, Zicarelli, F., Arney, D., Rosa, G. de
The aim of this study was to investigate the effect pre-partum habituation in the milking parlour on behaviour and lactation performance of buffalo heifers. Sixteen buffalo heifers in late gestation were used for this study. The animals, with an age ranging from 30 to 44 months at the start of...
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...
Environmental complexity and use of space in slow growing free range chickens
Contributor(s):: Rodriguez-Aurrekoetxea, A., Leone, E. H., Estevez, I.
Production environments for meat poultry are generally bi-dimensional open areas where birds tend to cluster along the walls. We investigated the impact of increasing environmental complexity (EC) on slow-growing free-range chickens raised under commercial conditions. The study was conducted in...
