Filial imprinting, environmental enrichment, and music application – Effects on behavior and performance of meat strain chicks

In conclusion, these preliminary studies on the combined effects of filial imprinting, environmental enrichment, and music on the performance and behavior of meat type chicks, suggest the possible benefits of these procedures, such as reduction of stress behavior [fear response]...

Perch use, plumage and foot condition and bone strength in caged hens

Caging laying hens restricts movement, reduces bone strength, and affects foot conditions and plumage quality. This experiments determined whether providing perches influenced these variables. There were five treatments: front perch, rear perch, front + rear perch, long perch and control...
