Poultry behavior
Knowledge of the behaviour of the stock and the application of that knowledge in the care of the stock plays an important part in the maximisation of production efficiency of a poultry production enterprise. In addition, the management of the domestic fowl has received considerable attention over recent years from the community, particularly animal liberation groups, because of the way that commercial poultry management systems have intensified. As a consequence, the study of poultry behaviour is important to the unit manager, not only to ensure that the welfare of the birds and production efficiency are maintained but also to minimise the influence of what is often uninformed debate. Behaviour is the way that animals respond to the different stimuli they encounter in their environment. The stimuli may be from other birds, their environment, people or any other thing or occurrence. Aggression and feather pecking or plucking are the two most common behavioral problems in chickens.

Environmental factors encountered during pre-natal life influence the developmental trajectory of a developing embryo, altering post-natal phenotypes (Du et al., 2015). Maternal nutrition and stress directly influence the maternal environment, with both factors prominent in the broiler breeder industry. Broiler breeders are feed restricted to improve reproductive output; however evidence suggests hens suffer from chronic stress due to prolonged hunger (Mench, 2002). Feed restriction in...

1. Introduction Contact dermatitis is an inflammation and irritation of the skin due to contact with an irritant or allergen. A common type of contact dermatitis in broiler chickens is footpad dermatitis (FPD), with necrotic lesions on the plantar surface of the central footpad [1].

This study tested whether rearing in aviaries, as opposed to cages, reduces the fearfulness of laying hens after transfer to furnished cages. Fear responses were recorded as avoidance of a novel object in the home cage. Lohmann Selected Leghorns were reared in an aviary system or conventional rearing cages and then transported...

Two days ago 8000 broiler chicks came from Malaysia after a 42 hours journey. They seemed to be highly dehydrated and were initially given water with electrolytes and multivitamin.
