Genetic analysis of reactivity to humans in Goettingen minipigs
Contributor(s):: Kohn, F., Sharifi, A. R., Simianer, H.
Goettingen minipigs are laboratory animals with an increasing demand over the last few years. At the moment, Goettingen minipigs are not selected for a low reactivity to humans and this trait is not included in the breeding programme. However, it is obvious that there is a need for genetically...
A scoring system to evaluate physical condition and quality of life in geriatric zoo mammals
Contributor(s):: Follmi, J., Steiger, A., Walzer, C., Robert, N., Geissbuhler, U., Doherr, M. G., Wenker, C.
The decision to perform euthanasia in geriatric zoo mammals is usually a highly complex procedure involving ethical, medical, emotional and sometimes political factors. However, subsequent necropsies show that the pathological changes of organs and/or the musculoskeletal system are often already...
Animal welfare: establishing a dialogue between science and society. (Special Issue: Knowing animals.)
Contributor(s):: Miele, M., Veissier, I., Evans, A., Botreau, R.
Farm animal welfare has become an important issue for the European public, especially in the last two decades when a number of crises (eg Bovine Spongiform Encephalopathy and Avian Influenzalu) have affected farm animal populations. Public concern about this issue led the European Union to fund...
Early detection of lameness in heifers with hairy heel warts using a pressure plate
Contributor(s):: Almeida, P. E., Mullineaux, D. R., Raphael, W., Wickens, C., Zanella, A. J.
Lameness is an indicator of pain and suffering, which has substantial animal welfare and economic impact on the dairy industry. Subjective locomotion scoring is unreliable for detecting mild cases of lameness in dairy herds. Undetected lameness can progress to a more serious and painful state...
Effect of training on the inter-observer reliability of lameness scoring in dairy cattle
Contributor(s):: March, S., Brinkmann, J., Winkler, C.
In the present study, the effect of training on inter-observer reliability was studied for a 5-category lameness scoring system used for routine on-farm surveys of welfare in dairy cattle. The inter-observer agreement between an experienced and an initially inexperienced observer was determined...
Genetic parameters for birth difficulty, lamb vigour and lamb sucking ability in Suffolk sheep
Contributor(s):: Macfarlane, J. M., Matheson, S. M., Dwyer, C. M.
This study investigates the genetic basis of lamb vigour (defined as neonatal lamb activity and sucking ability) and lambing difficulty as potential traits to be included in selection programmes to improve ewe and lamb welfare. Scores for lamb birth difficulty, vigour and sucking ability were...
Observer reliability for working equine welfare assessment: problems with high prevalences of certain results
Contributor(s):: Burn, C. C., Pritchard, J. C., Whay, H. R.
Welfare issues relevant to equids working in developing countries may differ greatly to those of sport and companion equids in developed countries. In this study, we test the observer reliability of a working equine welfare assessment, demonstrating how prevalence of certain observations reduces...
Reliability of a subjective lameness scoring system for dairy cows
Contributor(s):: Brenninkmeyer, C., Dippel, S., March, S., Brinkmann, J., Winckler, C., Knierim, U.
Four observers were trained in lameness assessment using a subjective scoring system with five categories, and observer agreement was investigated four times at different stages of training and experience. Inter-observer reliability increased with time and reached acceptable levels in the last...
Welfare assessment on Japanese dairy farms using the Animal Needs Index
Contributor(s):: Seo, T., Date, K., Daigo, T., Kashiwamura, F., Sato, S.
The Animal Needs Index (ANI) is used for on-farm assessment of welfare in Austria. However, no synthetic welfare assessment system exists in Japan. We performed a welfare assessment of Japanese dairy farms using the ANI scoring system. On 25 farms, 36 dairy herds were assessed using the...
