| 摘 要： | 蛋白质饲料原料资源紧张和养殖氮排放污染是我国蛋鸡业面临的主要难题。为此，蛋鸡低蛋白日粮在近年来应运而生，逐渐成熟。相关研究多以标准回肠可消化氨基酸为依据来配制蛋鸡低蛋白日粮，以期减少蛋白质饲料原料消耗、降低养殖成本、减少氮排放。本文简述了低蛋白日粮技术的理论基础及其在蛋鸡上的研究进展，旨在为低蛋白饲料在蛋鸡生产上的应用提供参考。

| Abstract: | Scarcity of feed protein source and nitrogen emission pollution are important problems in poultry industry. For this reason, low-protein diets for laying hens came into being in recent years and was gradually widely used. Low-protein diets of laying hens in recent studies were mainly formulated according to the standard ileal digestible amino acid content of feedstuffs, in order to reduce protein resources consumption, feeding cost, and nitrogen emission. Here, the theoretical basis of low-protein diet and its research progress in laying hens were briefly reviewed, aiming to improve the application of low-protein diet in laying hens. |
