  1. Exploring stock managers' perceptions of the human-animal relationship on dairy farms and an association with milk production

    Contributor(s):: Bertenshaw, C., Rowlinson, P.

    A human's attitude towards animals influences their behavior around animals, thus affecting the quality of the human-animal relationship (HAR). Many scientific studies have demonstrated that cattle's fear-response to humans affects their productivity, behavior, and welfare. In the scientific...

  2. Assessment of sheep welfare using on-farm registrations and performance data

    Contributor(s):: Stubsjoen, S. M., Hektoen, L., Valle, P. S., Janczak, A. M., Zanella, A. J.

    Farm animal welfare is a societal concern, and the need exists for scientific protocols to assess welfare. This paper describes the development of a protocol to assess the welfare of sheep (Ovis aries) and its application in 36 farms in Norway. There were two parts to the protocol; the animal-...

  3. Associations between lesion-specific lameness and the milk yield of 1,635 dairy cows from seven herds in the Xth region of Chile and implications for management of lame dairy cows worldwide

    Contributor(s):: Green, L. E., Borkert, J., Monti, G., Tadich, N.

    Lameness is one of the greatest infringements of welfare in dairy cows. The objective of this study was to investigate associations between milk yield and foot lesions causing lameness in Chilean dairy cattle with the hypothesis that if we can demonstrate that lameness reduces yield, and so...

  4. Assurance schemes as a tool to tackle genetic welfare problems in farm animals: broilers

    Contributor(s):: Cooper, M. D., Wrathall, J. H. M.

    Farm assurance schemes can set standards to assure compliance with specific requirements relating to animal welfare. As such, standards can be set to address genetic-related welfare problems in farm animals, such as those associated with fast growth rates in meat chickens (broilers) (Gallus...

  5. Environmental enrichment for captive Eastern blue-tongue lizards ( Tiliqua scincoides )

    Contributor(s):: Phillips, C. J. C., Jiang, Z., Hatton, A. J., Tribe, A., Bouar, M. le, Guerlin, M., Murray, P. J.

    Eastern blue-tongue lizards (Tiliqua scincoides) are kept in zoos and increasingly commonly as exotic pets, but little is known about improving their welfare by enrichment of their environment. Using nine animals kept individually in cages provided with a brick for basking and a pipe for hiding,...

  6. 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...

  7. Genomic dairy cattle breeding: risks and opportunities for cow welfare

    Contributor(s):: Mark, T., Sandoe, P.

    The aim of this paper is to discuss the potential consequences of modern dairy cattle breeding for the welfare of dairy cows. The paper focuses on so-called genomic selection, which deploys thousands of genetic markers to estimate breeding values. The discussion should help to structure the...

  8. Nest provision influences reproductive success in breeding blue fox vixens: a preliminary study

    Contributor(s):: Pyykonen, T., Ahola, L., Hanninen, S., Mononen, J.

    The aim of the present study was to evaluate the effects of an unfamiliar nest and environmental enrichment, ie provision of an additional nest, on farmed blue fox (Alopex lagopus) vixens' reproductive performance. Two experimental groups were evaluated in the study: (i) a single nest (SN) group...

  9. Piglet mortality on farms using farrowing systems with or without crates

    Contributor(s):: Weber, R., Keil, N. M., Fehr, M., Horat, R.

    Crating sows in farrowing systems greatly restricts their normal behaviour, which is usually justified by the assumption that piglet mortality is higher with loose-housed sows. Based on experiments showing that this is not the case, farrowing crates were banned in Switzerland in 1997. Since then,...

  10. Reducing post-mixing aggression and skin lesions in weaned pigs by application of a synthetic maternal pheromone

    Contributor(s):: Guy, J. H., Burns, S. E., Barker, J. M., Edwards, S. A.

    In commercial pig production, piglets are often mixed after weaning which can result in severe aggression and lead to body damage, disruption of feeding behaviour and reduced growth. This experiment investigated whether application of a synthetic maternal pheromone to groups of weaned pigs in...

  11. Stocking density and stress induction affect production and stress parameters in broiler chickens

    Contributor(s):: Villagra, A., Ruiz de la Torre, J. L., Chacon, G., Lainez, M., Torres, A., Manteca, X.

    The objective of this paper is to analyse the effects of three different stocking densities on the production, stress and fear parameters of female broilers during a 46-day production period. Chickens were randomly distributed among nine floor pens in groups of 30 broilers with different space...

  12. The effect of management system on mortality and other welfare indicators in Pennsylvania dairy herds

    Contributor(s):: Dechow, C. D., Smith, E. A., Goodling, R. C.

    The objective of this study was to identify farm characteristics that were associated with cow (Bos taurus) welfare outcomes, including mortality rate, culling by 60 days of lactation, survival to >=6 years of age and >=5th parity (aged cows), somatic cell score, milk yield, and milk composition....

  13. The impact of genetic selection for increased milk yield on the welfare of dairy cows

    Contributor(s):: Oltenacu, P. A., Broom, D. M.

    Milk yield per cow has more than doubled in the previous 40 years and many cows now produce more than 20,000 kg of milk per lactation. The increase in production should be viewed with concern because: (i) the increase in milk yield has been accompanied by declining fertility, increasing leg and...

  14. Validation of an Animal Needs Index for cattle using Test Theory

    Contributor(s):: Herva, T., Peltoniemi, O., Virtala, A. M.

    The validity of an ANI-based welfare index for cattle, the A-Index, was evaluated using Test Theory methods described for quality of life assessments in human medicine. Content validity was considered during the modification of the Index for Finnish beef production. In total, 43 items evaluating...
