Abstract The effect of dietary arginine on disease prevention, immune system modulation, the gut micro-biota composition and growth of broiler chicken was reviewed. The main aim of poultry production is the maximization of profit at the least possible cost. This objective can mainly be achieved by ensuring that there is no interference in growth or disease outbreak and by feeding chicken with the best possible level of nutrients. With the ban on antibiotic growth promoters, attention is shifted towards other nutrition methods to prevent diseases and promote growth. More attention is therefore given to protein diets in animal nutrition due to their importance as essential part of active biological compounds in the body, assisting in the breakdown of body tissue and helping in the physiological processes of the animal. Arginine plays important function in serving as building blocks of proteins and polypeptides. It performs other roles during the regulation of important biochemical functions such as maintenance, growth, reproduction and immunity. Arginine cannot be synthesized by the body so it has to be supplemented in the diet. When arginine is supplemented above the recommended level, the gut mucosa is protected, immunosuppression is alleviated, diseases like necrotic enteritis, infectious bursal disease and coccidiosis in broiler chickens are prevented. There is an improvement in growth resulting from the increase in intestinal absorption, barrier function and microbiota composition.

精氨酸在肉鸡疾病预防、肠道菌群调节、生长性能和免疫系统中的作用

摘要 综述了日粮精氨酸对肉鸡疾病预防、免疫系统调节、肠道菌群组成和生长的影响。家禽生产的主要目标是以尽可能低的成本实现利润最大化。这个目标主要可以通过确保生长或疾病爆发不受干扰以及用尽可能高的营养水平喂养鸡来实现。随着抗生素生长促进剂的禁用，注意力转向其他营养方法，以预防疾病和促进生长。因此，更多关注动物营养中的蛋白质饮食，因为它们作为体内活性生物化合物的重要组成部分，有助于身体组织的分解和动物的生理过程。精氨酸在作为蛋白质和多肽的构建块中起着重要的作用。它在调节重要的生化功能（如维持、生长、繁殖和免疫）期间发挥其他作用。人体不能合成精氨酸，因此必须在饮食中补充。当精氨酸补充超过推荐水平时，可以保护肠道粘膜，减轻免疫抑制，预防肉鸡坏死性肠炎、传染性法氏囊病和球虫病等疾病。由于肠道吸收、屏障功能和微生物群组成的增加，生长得到改善。繁殖和免疫。人体不能合成精氨酸，因此必须在饮食中补充。当精氨酸补充超过推荐水平时，可以保护肠道粘膜，减轻免疫抑制，预防肉鸡坏死性肠炎、传染性法氏囊病和球虫病等疾病。由于肠道吸收、屏障功能和微生物群组成的增加，生长得到改善。繁殖和免疫。人体不能合成精氨酸，因此必须在饮食中补充。当精氨酸补充超过推荐水平时，可以保护肠道粘膜，减轻免疫抑制，预防肉鸡坏死性肠炎、传染性法氏囊病和球虫病等疾病。由于肠道吸收、屏障功能和微生物群组成的增加，生长得到改善。
