  1. Slow and steady wins the race? No signs of reduced welfare in smaller broiler breeder hens at four weeks of age

    Contributor(s):: Lindholm, C., Calais, A., Jonsson, J., Yngwe, N., Berndtson, E., Hult, E., Altimiras, J.

    Broiler breeder chickens are commonly reared under strict feed-restriction regimes to reduce obesity-induced health and fertility problems during adult life, and are assumed to experience a reduced welfare due to the resulting hunger. In these conditions, feed competition could influence the...

  2. 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...

  3. Measuring motivation in swine: the food-metric scale

    Contributor(s):: Patterson-Kane, E. G., Kirkden, R. D., Pajor, E. A.

    Understanding how nonhuman animals such as swine respond to their environment and understanding how to provide them with a good quality of life involves using a range of experimental approaches. More and more, ethological researchers are turning to operant methods to answer some of these...

  4. Attitudes of Canadian beef producers toward animal welfare

    Contributor(s):: Spooner, J. M., Schuppli, C. A., Fraser, D.

  5. Measuring the success of a farm animal welfare education event

    Contributor(s):: Jamieson, J., Reiss, M. J., Allen, D., Asher, L., Wathes, C. M., Abeyesinghe, S. M.

  6. 'Freedom from hunger' and preventing obesity: The animal welfare implications of reducing food quantity or quality

    Contributor(s):: D

  7. Equine welfare and ethics

    Contributor(s):: Rollin, B.

  8. Animal welfare: European legislation and future perspectives

    Contributor(s):: Bonafos, L., Simonin, D., Gavinelli, A.

  9. How hungry are broiler breeders subjected to commercial food restriction during rearing?

    Contributor(s):: Savory, C. J., Maros, K., Rutter, S. M.

  10. Why do pigs root and in what will they root? A review on the exploratory behaviour of pigs in relation to environmental enrichment

    Contributor(s):: Studnitz, M., Jensen, M. B., Pedersen, L. J.

    The intention of the new European legislation on rooting materials for pigs is to improve the welfare of pigs. The question is: which materials are suitable rooting materials for pigs? To answer this question the motivation for exploration in pigs is elucidated and the needs of the pigs in this...

  11. Effect of scattered feeding and feeding twice a day during rearing on indicators of hunger and frustration in broiler breeders

    Contributor(s):: Jong, I. C. de, Fillerup, M., Blokhuis, H. J.

    Broiler breeders are routinely fed restricted during rearing which has a major negative effect on their welfare. They suffer from hunger and frustration from thwarting of feeding. The aim of this experiment was therefore to study if broiler breeder welfare can be improved by changes in the...

  12. Ethics of feeding: the omnivore dilemma

    Contributor(s):: Kasanen, I. H. E., Sorensen, D. B., Forkman, B., Sandoe, P.

    The way in which animals are fed is an important aspect of their welfare. Not only does food provide the energy and nutrients vital for survival, but feeding is also associated with a number of other factors contributing to the well-being of animals. The feeding method can determine the animals'...

  13. Zoomorphism and anthropomorphism: fruitful fallacies? (Special Issue: Knowing animals.)

    Contributor(s):: Webster, J.

    Zoo- and anthropomorphism may both be scientific heresies but both may serve as a basis for thought (and real) experiments designed to explore our ability to assess quality of life as perceived by another sentient animal. Sentience, a major contributor to evolutionary fitness in a complex...
