中文摘要:
      精氨酸是肉鸡的一种功能性必需氨基酸,具有多种生理功能。综述了精氨酸对肉鸡生长、胴体品质、肉品质、肠道健康、免疫和抗氧化等方面的研究进展,分析了适宜精氨酸需要量及其与赖氨酸的互作关系,并总结了精氨酸替代物胍基乙酸和 N- 氨甲酰谷氨酸在肉鸡生产上的应用研究。饲粮精氨酸水平适宜有利于提高肉鸡生长性能,改善胴体品质和肉品质,修复肠道损伤,维持正常肠道屏障功能,调节肠道微生物菌群,调控肠道消化酶活性和氨基酸转运载体表达,以及提高免疫功能和抗氧化能力。饲粮精氨酸不足或者过多,均不利于肉鸡的正常生长发育。肉鸡精氨酸需要量受品种类型、性别、饲养阶段、精氨酸 / 赖氨酸比值等因素影响。目前大部分研究主要集中在快大型白羽肉鸡,对我国特有的黄羽肉鸡精氨酸需要量研究报道较少,其研究结果也存在较大差异。胍基乙酸和 N- 氨甲酰谷氨酸作为精氨酸替代物,对肉鸡的作用不同。胍基乙酸不能完全替代精氨酸,但饲粮中补充胍基乙酸能够减少精氨酸用于能量代谢,使其更多用于肌肉生长和其他生理功能。N- 氨甲酰谷氨酸能够增加肉鸡内源性精氨酸合成,提高体内精氨酸含量,促进肉鸡生长发育。随着精氨酸及其替代物对肉鸡作用效果和机理研究的不断深入,精氨酸的需要量将更加精准,其在肉鸡生产上的应用将越来越广泛,有助于进一步改善肉鸡生产性能,提高饲料利用效率。
英文摘要:
      Arginine is a functional essential amino acid in broilers with a variety of physiological functions. The research progress of arginine in growth, carcass quality, meat quality, intestinal health, immunity and antioxidation in broilers was reviewed, and the appropriate requirement of arginine and its interaction with lysine were analyzed. At the same time, the application of arginine substitutes guanidinoacetic acid and N-carbamoylglutamic acid in broiler production were summarized. Appropriate level of arginine in diet is beneficial to improve growth performance, carcass quality and meat quality, repair intestinal injury, maintain normal intestinal barrier function, regulate intestinal microflora, regulate the expression of intestinal digestive enzymes and amino acid transporters, and improve immunity and antioxidation capacity. Insufficient or excessive arginine in the diet is not conducive to the normal growth and development of broilers. The arginine requirement of broilers is affected by breed type, sex, feeding stage, ratio of arginine to lysine and so on. At present, most of the studies mainly focus on fast-growth white-feathered broilers, but there are few reports on the arginine requirement of yellow-feathered broilers in China, and the research results are quite different. As substitutes for arginine, guanidinoacetic acid and N-carbamoylglutamic acid have different effects on broilers. Guanidinoacetic acid does not completely replace arginine, but dietary supplementation with guanidinoacetic acid can reduce the use of arginine in energy metabolism and make it more useful for muscle growth and other physiological functions. N-carbamoylglutamic acid can increase the synthesis of endogenous arginine, increase the content of arginine in vivo and promote the growth of broilers. With the deepening of the studies on the effect and mechanism of arginine and its substitutes on broilers, the requirements of arginine will be more accurate, and be widely used in broiler production. It will help to further improve the production performance of broilers and improve feed utilization efficiency.
