The current development of animal husbandry in China is constrained by the insufficient sup-ply of conventional feed resources,which affects the production and sustainable development of laying hens.There are a variety of nonconventional feed types with low price and rich nutrients,which can re-place some conventional feeds such as corn and soybean meal to provide nutrients for laying hens to meet their production and maintenance needs.And they have high feeding value.This paper mainly reviews the application of unconventional feed in Layer production in terms of the types and nutritions of unconvention-al feed,in order to provide reference for the research and application of it in laying hens production.
