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...

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 -...
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...
A project to clone companion animals
| Contributor(s):: Hawthorne, L.
A 'special feature' article by the Project Coordinator of MIssyplicity, a Genetic Savings & Clone (GSC) project seeking to clone a specific mixed breed dog, named Missy, owned by an anonymous yet wealthy individual.
Cloning companion animals is wrong
| Contributor(s):: Bok, H.
"... Cloning is not safe, and it is not widely understood. Nevertheless, I suppose that some extremely compelling reason might justify our cloning animals. However, there is no such justification for the Missyplicity Project." ...
Dog breeding in New Providence, the Bahamas, and its potential impact on the roaming dog population I: planned and accidental
| Contributor(s):: Fielding, W. J.
This article reports the first known study on dog breeding in an Afro-Caribbean community. The study obtained the information on 517 matings through interviews with dog caregivers. Few litters (6.8%) from mongrels (potcakes) resulted from planned matings, whereas 66.5% of matings between purebred...
New dog: old tricks
| Contributor(s):: Greene, M.
In this article, the author examines the strategy underlying the code of ethical practice established by Genetic Savings & Clone (GSC) as they progressed toward commerical cloning of campanion animals.
Preliminary investigation of morphological differences between ten breeds of horses suggests selection for paedomorphosis. (Special Issue: Equitation science.)
| Contributor(s):: Goodwin, D., Levine, M., McGreevy, P. D.
Paedomorphosis is the retention of juvenile morphology at maturity and is important in generating evolutionary change in domestic species and species in the wild. When comparing dogs with the wolf, this preliminary study saw paedomorphosis in their physical and behavioural traits (Goodwin,...
Producer or purchaser: different expectations may lead to equine wastage and welfare concerns. (Special Issue: Equitation science.)
| Contributor(s):: Hennessy, K. D., Quinn, K. M., Murphy, J.
Horses are individual, each having differential characteristics such as height, colour, breeding, conformation, and temperament. These bio-characteristics often influence potential purchasers when buying horses. This study sought to investigate if producers and potential purchasers placed similar...
Effects of stocking rate on measures of efficacy and welfare during carbon dioxide gas euthanasia of young pigs
| Contributor(s):: Fiedler, K. J., Parsons, R. L., Sadler, L. J., Millman, S. T.
The objective of this study was to evaluate the effects of chamber stocking rate on facets of animal welfare and efficacy during gas euthanasia of young pigs ( Sus scrofa domesticus). Crossbred pigs (390 neonatal and 270 weaned) designated for euthanasia at production farms were randomly assigned...
Purebred dogs and canine wellbeing
| Contributor(s):: Jeppsson, S.
Breeders of purebred dogs usually have several goals they want to accomplish, of which canine wellbeing is one. The purpose of this article is to investigate what we ought to do given this goal. Breeders typically think that they fulfil their wellbeing-related duties by doing the best they can...

Relationships between young stallions' temperament and their behavioral reactions during standardized veterinary examinations
| Contributor(s):: Peeters, M., Verwilghen, D., Serteyn, D., Vandenheede, M.
Horse handling and veterinary examination can induce hazardous stress reactions. Such reactions occur especially in young and less-trained horses, particularly stallions, and make their handling a risk for breeders, grooms, and medical staff. Moreover, these stressful situations will affect the...
The effect of breed on age-related changes in behavior and disease prevalence in cognitively normal older community dogs, Canis lupus familiaris
| Contributor(s):: Salvin, H. E., McGreevy, P. D., Sachdev, P. S., Valenzuela, M. J.
Variation in breed longevity in the dog has led to the inference that large dogs age at a faster rate than small dogs, possibly because of an increased oxidative load. Potential differences in behavioral aging (the rate of age-related decline in cognito-behavioral performance) across breeds...
