  10. The Role of Tryptophan-Kynurenine in Feather Pecking in Domestic Chicken Lines

    | Contributor(s):: Patrick Birkl, Jacqueline Chow, Paul Forsythe, Johanna M. Gostner, Joergen B. Kjaer, Wolfgang A. Kunze, Peter McBride, Dietmar Fuchs, Alexandra Harlander-Matauschek

    Research into the role of tryptophan (TRP) breakdown away from the serotonergic to the kynurenine (KYN) pathway by stimulating the brain-endocrine-immune axis system interaction has brought new insight into potential etiologies of certain human behavioral and mental disorders. TRP is involved...

  14. Feather Pecking and Cannibalism in Non-Beak-Trimmed Laying Hen Flocks—Farmers' Perspectives

    Full-text: Available

    | Contributor(s):: Eija Kaukonen, Anna Valros

    Pecking-related problems are common in intensive egg production, compromising hen welfare, causing farmers economic losses and negatively affecting sustainability. These problems are often controlled by beak trimming, which in Finland is prohibited. An online questionnaire aimed to collect...

  15. Rewarding memories? Behaviour of broiler chickens towards peat in flocks with and without previous exposure to peat

    | Contributor(s):: Vas, Judit, BenSassi, Neila, Vasdal, Guro, Newberry, Ruth C.

    Under commercial conditions, environmental provisions assumed to have an enriching effect on broiler chicken welfare may be offered infrequently and at limited locations, raising questions about their enrichment value. We hypothesized that, if broilers given limited access to peat remembered peat...

  16. Play behaviour reduced by environmental enrichment in fast-growing broiler chickens

    | Contributor(s):: Liu, Zhenzhen, Torrey, Stephanie, Newberry, Ruth C., Widowski, Tina

    The objective of this study was to evaluate effects of environmental enrichment on play behaviour in fast-growing broiler chickens. Chicks (19 of each sex) were randomly assigned to 6 non-enriched (NE) pens and 6 pens enriched (E) with a raised platform, hanging weighing scale, peck stone, and...

  17. Breed-related differences in the preference for inanimate objects between chicks of laying hens

    | Contributor(s):: Kasperek, Kornel, Zięba, Grzegorz, Pluta, Adrian, Ziemiańska, Agnieszka, Rozempolska-Rucińska, Iwona

    Our previous study showed significant behavioural differences between breeds of laying hens. Birds differed in their excitability, reactivity, decision-making speed, behavioural strategy, and interest in elements of the surroundings. The results of our investigations and studies conducted by...

  18. Range use is related to free-range broiler chickens’ behavioral responses during food and social conditioned place preference tests

    | Contributor(s):: Ferreira, Vitor Hugo Bessa, Germain, Karine, Calandreau, Ludovic, Guesdon, Vanessa

    Free-range broiler chickens usually show an uneven spatial utilization of an outdoor range. Due to behavioral and cognitive between-individual differences, some animals may be driven to associate food and conspecifics more strongly to the barn, causing them to be less prone to explore the range....

  19. Effects of environmental enrichment on activity and lameness in commercial broiler production

    | Contributor(s):: Vasdal, Guro, Vas, Judit, Newberry, Ruth C., Moe, Randi Oppermann

    The aim of this pilot study was to investigate the effects of commercially applied environmental enrichments on behavior and lameness in broilers. Two consecutive flocks of broilers were observed at 16 days and 30 days of age to investigate differences between enriched (peat, bales of lucerne...

  20. Sward botanical composition and sward quality affect the foraging behaviour of free-range laying hens

    | Contributor(s):: Breitsameter, Laura, Gauly, Matthias, Isselstein, Johannes

    In a two-year experiment, we investigated the influence of sward plant species composition (sward type), stocking duration and state of sward degradation on the foraging behaviour of chickens. Laying hens (ISA Warren) were pastured on 15 sward types including 14 monocultures of grassland plant...
