Laying Hens Under Low Protein Diet: Fatty Liver Bleeding Syndrome Research

Abstract

The egg industry in China is currently confronted with significant challenges, including a scarcity of protein feedstock resources and nitrogen that contribute to pollution in animal husbandry. To address these issues, the adoption of low-protein diets for laying hens has gained traction and evolved over the years. Research in this area frequently utilizes standardized ileal digestible amino acids as a fundamental component in developing low-protein diets for laying hens. The primary objectives of these diets are decrease the consumption of protein feedstock, reduce farming expenses, and alleviate nitrogen emissions. This paper provides a concise overview of the theoretical framework behind low-protein diet technology and advancements in research on laying hens, with the intention of offering guidance for the implementation of low-protein feeds in egg production.
