Environmental enrichment is a measure to deal with these problems. Therefore, an enrichment device offering maize silage automatically was tested in two...

  5. More eggs but less social and more fearful? Differences in behavioral traits in relation to the phylogenetic background and productivity level in laying hens

    | Contributor(s):: Dudde, Anissa, Schrader, Lars, Weigend, Steffen, Matthews, Lindsay R., Krause, E. Tobias

    Different lines of laying hens have undergone a strong selection pressure for productivity traits, which has been proposed as a potential cause of undesirable side effects like behavioural disorders. One reason for such behavioral changes might be due to energy trade-offs, as high productive...

  6. Human-animal interactions: Survey of contact behavior relevant for the spread of infectious diseases

    | Contributor(s):: Yimer Wasihun Kifle

    Background: Approximately 75 percent of recently emerging infectious diseases that affect humans are diseases of animal origin, and approximately 60 percent of all human pathogens are zoonotic. Contact between humans and pets, livestock, poultry and other animals could enable transmission of...

  7. Ranging Behaviour of Commercial Free-Range Broiler Chickens 2: Individual Variation

    | Contributor(s):: Peta S Taylor, Paul H Hemsworth, Peter J Groves, Sabine G Gebhardt-Henrich, Jean-Loup Rault

    Little is known about broiler chicken ranging behaviour. Previous studies have monitored ranging behaviour at flock level but whether individual ranging behaviour varies within a flock is unknown. Using Radio Frequency Identification technology, we tracked 1200 individual ROSS 308 broiler...

  8. Ranging Behaviour of Commercial Free-Range Broiler Chickens 1: Factors Related to Flock Variability

    | Contributor(s):: Peta S Taylor, Paul H Hemsworth, Peter J Groves, Sabine G Gebhardt-Henrich, Jean-Loup Rault

    Little is known about the ranging behaviour of chickens. Understanding ranging behaviour is required to improve management and shed and range design to ensure optimal ranging opportunities. Using Radio Frequency Identification technology, we tracked 300 individual broiler chickens in each of four...

  9. Social networks and welfare in future animal management

    | Contributor(s):: Koene, P., Ipema, B.

    It may become advantageous to keep human-managed animals in the social network groups to which they have adapted. Data concerning the social networks of farm animal species and their ancestors are scarce but essential to establishing the importance of a natural social network for farmed animal...

  10. Attitudes of veterinary students in Croatia toward farm animal welfare

    | Contributor(s):: Ostovic, M., Mesic, Z., Mikus, T., Matkovic, K., Pavicic, Z.

    This survey was undertaken to assess the attitudes of Croatian veterinary students regarding farm animal welfare issues. The study included students of all undergraduate years at the only Faculty of Veterinary Medicine in Croatia. First-year students were surveyed twice, ie before and after...

  11. Farmer attitudes to injurious pecking in laying hens and to potential control strategies

    | Contributor(s):: Palczynski, L. J., Buller, H., Lambton, S. L., Weeks, C. A.

    Farmers' recognition of health and welfare problems, and their responses to related intervention programmes, such as those to reduce injurious pecking in hens, directly influence the welfare of animals in their care. Changing those responses can be achieved through a re-positioning of social...

  12. Effects of carprofen, meloxicam and butorphanol on broiler chickens' performance in mobility tests

    | Contributor(s):: Hothersall, B., Caplen, G., Parker, R., Nicol, C. J., Waterman-Pearson, A. E., Weeks, C. A., Murrell, J. C.

    Lame broiler chickens perform poorly in standardised mobility tests and have nociceptive thresholds that differ from those of non-lame birds, even when confounding factors such as differences in bodyweight are accounted for. This study investigated whether these altered responses could be due to...

  13. Tree cover and injurious feather-pecking in commercial flocks of free-range laying hens: a follow up

    | Contributor(s):: Bright, A., Gill, R., Willings, T. H.

    Injurious feather-pecking in non-cage systems is a serious economic and welfare concern for the egg-producing industry. This study presents results from data of over 1,000 flocks from producers who supplied free-range eggs to McDonald's Restaurants Ltd UK between 2008 and 2013. These producers...

  14. Consumer attitudes to injurious pecking in free-range egg production

    | Contributor(s):: Bennett, R. M., Jones, P. J., Nicol, C. J., Tranter, R. B., Weeks, C. A.

    Free-range egg producers face continuing problems from injurious pecking (IP) which has financial consequences for farmers and poor welfare implications for birds. Beak-trimming has been practised for many years to limit the damage caused by IP, but with the UK Government giving notification that...

  15. The contribution of broiler chicken welfare certification at farm level to enhancing overall animal welfare: the case of Brazil

    | Contributor(s):: Souza, A. P. O., Molento, C. F. M.
