Abstract:

Feather pecking is a common and serious act of destruction in the production of laying hens, which can cause damage to the feathers and skin of the pecked chickens, and even results in mortality. Feather pecking not only does negative impact on the health and well-being of laying hens, but also further affects the benefit of farming layers, therefore received extensive attention from the layer industry and research. This review aims to synthesize the existing research results to explore the external influencing factors and genetic regulatory mechanisms of feather pecking behavior of laying hens, so as to promote the in-depth understanding of feather pecking behavior of laying hens, and put forward future research directions. This provides the basis for developing sustainable solutions, improving the welfare of laying hens, and increasing production efficiency.

Key words: laying hens, feather pecking, animal welfare, factors, ethology
