Abstract

The invention relates to a high-efficacy environment-friendly compound feed for layer hens, fundamentally solving the problems of high content of crude protein, poor quality of protein and large discharge of nitrogen and phosphorus in the prior feed formulation. In the material composition of the compound feed, the balance model of digestible lysine: digestible methionine+ digestible cystine: digestible threonine: digestible tryptophan is 100:87:71:18. The invention has the advantages of reasonable design, environment protection, energy saving, improvement of laying rate, reduction of feed-egg ratio, reduction of the discharge of fecal nitrogen and fecal phosphorus and improvement of the economic benefits of enterprises.

Description

technical field [0001] The invention relates to a feed for laying hens, in particular to a high-efficiency and environment-friendly compound feed for laying hens which is reasonably configured according to the balance mode of digestible amino acids. Background technique [0002] In recent years, with the increase in the number of poultry breeding, the pressure of environmental protection and energy saving is increasing. The pollution of the poultry industry mainly comes from the excreta of nitrogen, phosphorus, trace elements, etc. These substances mainly come from undigested feed in the feed. Nutrients. These harmful substances not only destroy the environment of the chicken house, but also pose a great threat to the health of poultry, increase the incidence of poultry disease, and reduce the economic benefits of poultry farmers. Hazard to human health. [0003] At present, most laying hen breeders and feed companies only judge the quality of laying hen feed on the level ...
