  1. Effect of lower temperature stimuli during incubation on fear and social-related behaviours in broilers

    Contributor(s):: Verlinden, Sara Maria Daniel, Larsen, Mona Lilian Vestbjerg, Debontridder, Pauline, Youssef, Ali, Everaert, Nadia, Norton, Tomas

    Temperature is the most influential environmental parameter during egg incubation affecting embryo development, hatchability and post-hatch performance of broilers. Industrial incubation operates to control the temperature and humidity around the eggs closely based on predefined setpoints and...

    | 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...

  17. 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...

  18. 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...

  19. 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...

    | 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...
