  1. Feed-restricted broiler breeders: state-dependent learning as a novel welfare assessment tool to evaluate their hunger state?

    Contributor(s):: Buckley, L. A., Sandilands, V., Hocking, P. M., Tolkamp, B. J., D'Eath, R. B.

    This paper reports three experiments that aimed to validate the use of state-dependent learning (SDL) as a novel welfare assessment tool to evaluate the hunger state of feed-restricted broiler breeders. In each experiment, birds alternated every 2 days between two food rations: quantitative feed...

  2. Group composition for fattening entire male pigs under enriched housing conditions - influences on behaviour, injuries and boar taint compounds

    Contributor(s):: Holinger, M., Fruh, B., Hillmann, E.

    In organic farming, the production of pork from entire male pigs seems to be the most promising alternative to castration, as organic animal husbandry aims at high standards of animal welfare and elimination of mutilations. However, previous research on behaviour of entire male pigs was mostly...

  3. Head partitions at the feed barrier affect behaviour of goats

    Contributor(s):: Nordmann, E., Barth, K., Futschik, A., Palme, R., Waiblinger, S.

    Space allowance at the feeding places often forces goats to feed in close proximity, that is, less than their individual distances. In consequence, agonistic behaviour may increase as well as stress and injuries, while access to feed may decrease, especially in low-ranking goats. Partitions...

  4. Identifying environmental and management factors that may be associated with the quality of life of kennelled dogs ( Canis familiaris)

    Contributor(s):: Kiddie, J., Collins, L.

    This paper describes the use of a validated quality of life assessment tool (described elsewhere) to identify environmental and management factors that may affect quality of life in dogs kennelled in rehoming centres. Dogs were allocated to one of the four treatment groups, all of which had a...

  5. Influences of various factors on cows' entrance order into the milking parlour

    Contributor(s):: Polikarpus, A., Kaart, T., Mootse, H., Rosa, G. de, Arney, D.

    This study investigates the stability of the milking order of cows entering into the milking parlour of a commercial dairy herd, and changes to this order consequent to a change in health status and a change in the membership of the group of cows being milked. In large herds it is difficult for...

  6. Predicting time spent on different behavioural activities from physicochemical properties of fibrous diets in finishing pigs

    Contributor(s):: Bakare, A. G., Ndou, S. P., Madzimure, J., Chimonyo, M.

    The objective of the present study was to predict time spent on different behavioural activities by finishing pigs, using physicochemical measurements of fibrous feed. Eighty four Large White * Landrace barrows with 80.54.7 kg body weight (BW) at the beginning of the experiment were used. Feed...

  7. Stress assessment in small ruminants kept on city farms in Southern Germany

    Contributor(s):: Schilling, A. K., Reese, S., Palme, R., Erhard, M., Wohr, A. C.

    Sheep and goats are frequently used in nonhuman animal-assisted activities on city farms. There are few data available on this type of usage of small ruminants. Health evaluations, behavioral observations (feeding, resting, comfort, explorative and social behaviors), behavioral tests (human...

  8. The effect of overgrown claws on behaviour and claw abnormalities of sows in farrowing crates

    Contributor(s):: Diaz, J. A. C., Stienezen, I. M. J., Leonard, F. C., Boyle, L. A.

    The objective of this study was to evaluate the effect of overgrowth of the weight bearing claws on the behaviour of sows in farrowing crates. The study used 24 multiparous lactating sows, 13 with overgrown (OG) rear claws and 11 controls. Sows were video recorded continuously from approximately...

  9. The effects of a high-starch or high-fibre diet on equine reactivity and handling behaviour

    Contributor(s):: Bulmer, L., McBride, S., Williams, K., Murray, J. A.

    Increasing performance work in the horse is often associated with a reduction in the forage ration and an increase in concentrates, usually in the form of high-starch cereal grains. This type of diet has been associated with stereotypic behaviours and health problems. High-starch diets are also...

  10. Willingness of Dutch broiler and pig farmers to convert to production systems with improved welfare

    Contributor(s):: Gocsik, E., Lans, I. A. van der, Lansink, A. G. J. M. O., Saatkamp, H. W.

    The present study investigated 15 broiler and 13 fattening pig farmers' willingness-to-convert to alternative production systems with higher animal welfare standards compared to conventional production systems in The Netherlands, and explored the main barriers to the adoption of these alternative...

  11. Human and animal diet at Conchopata, Peru :stable isotope evidence for maize agriculture and animal management practices during the Middle Horizon

    Contributor(s):: Finucane, Brian

  12. Deconstructing the Regulatory Facade: Why Confused Consumers Feed their Pets Ring Dings and Krispy Kremes

    Contributor(s):: Justine S. Patrick

    Americans own more than 130 million cats and dogs and spend over $12 billion per year on commercial pet foods. The commercial pet food industry faces minimal substantive regulation, despite navigating several layers of regulation from various groups including the FDA, the American Association of...

  13. A conditioned response overrides social attraction in common carp: a possibility for low stress sorting strongly schooling fish?

    Contributor(s):: Mesquita, F. O., Borcato, F. L., Huntingford, F. A.

    In this study we investigated whether a conditioned response to a light cue can override the strong schooling tendency of common carp, with a view to identifying a possible system for low stress control of movement for captive fish. Carp were trained in groups of three to approach and bite a...

  14. Density-dependent diet selection and body condition of cattle and horses in heterogeneous landscapes

    Contributor(s):: Cornelissen, P., Vulink, J. T.

    For some decades, grazing by cattle and horses is used as a management tool to achieve different nature management goals. For managers there are still questions to be answered about the effects of herbivore densities on their performance, vegetation development and biodiversity. This study...

  15. Effect of pre- and post-partum sow activity on maternal behaviour and piglet weight gain 24 h after birth

    Contributor(s):: Illmann, G., Chaloupkova, H., Neuhauserova, K.

    Within the 24 h prior to parturition sows are active and motivated to perform nest-building behaviour. The aim of this study was to investigate: (i) whether pre-partum activity (e.g. nesting and postural changes) could predict maternal behaviour 24 h post-partum (pp) and weight gain 24 h pp, and...

  16. 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...
