  1. The Impacts of Colony Cages on the Welfare of Chickens Farmed for Meat

    Contributor(s):: Mace, Jenny L., Knight, Andrew

    There is growing interest in keeping meat chickens in modern colony cages (CCs) rather than conventional litter-floor barns. Suggested welfare improvements for chickens in such systems include reduced bodily lesions due to lower contact with flooring contaminated with faeces and urine, due to...

  2. Data Mining as a Tool to Infer Chicken Carcass and Meat Cut Quality from Autochthonous Genotypes

    Contributor(s):: González Ariza, Antonio, Navas González, Francisco Javier, León Jurado, José Manuel, Arando Arbulu, Ander, Delgado Bermejo, Juan Vicente, Camacho Vallejo, María Esperanza

    The present research aims to develop a carcass quality characterization methodology for minority chicken populations. The clustering patterns described across local chicken genotypes by the meat cuts from the carcass were evaluated via a comprehensive meta-analysis of ninety-one research...

  3. Red Junglefowl Chicks Seek Contact With Humans During Foraging Task

    Full-text: Available

    | Contributor(s):: Diana Rubene, Hanne Løvlie

    Contact seeking with humans is documented in some domestic animals, mainly dogs, which have advanced communication skills. Domestication as a companion animal is thought to underlie this ability. However, also domesticated horses and goats display similar human-directed behaviors. This suggests...

  4. 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...

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

    Full-text: Available

    | 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...

  19. 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...

  20. 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...
