摘要: 蛋白质是生命活动的最基本物质。随着反刍动物蛋白质营养研究的深入,如何最大化提高瘤胃微生物蛋白量,增加瘤胃后非降解蛋白(rumen undegraded protein, RUP)的消化率,合理搭配日粮,减少氮的排放量,通过日粮途径改善乳蛋白含量和产量,提高氮的利用率已成为当今研究的热点。同时,蛋白质、氨基酸和肽营养在瘤胃、小肠、大肠和乳腺中的代谢机理、影响其利用的因素还不是很清楚,但随着分子生物学技术、血插管技术和动静脉差异技术在蛋白质、氨基酸和肽的转运、吸收及乳蛋白合成机理上的应用,为深入研究其转运、利用机制提供了可能。牛奶中的活性功能成分近年来随着消费需求也日益成为研究的热点。作者主要从蛋白质如何在瘤胃内代谢及影响因素、小肠内代谢及影响因素、大肠内代谢及影响因素、乳腺内代谢和乳蛋白合成、乳中的免疫活性蛋白等方面对蛋白质营养研究作一综述。

Abstract: Protein is the basic nutrition for life. As research advanced how to increase the level of MCP in rumen and improve the digestibility of RUP effectively so as to decrease the nitrogen discharge have been the hot topic. While the mechanism of protein, amino acids and peptide were utilized in rumen, small intestine, large intestine and mammary gland were not clear. Now it is possible for us to study metabolism of protein, amino acids and peptide as the molecular biology, blood vessel intubation and arteriovenous disparity technique used. At the same time, active ingredients in milk have earned much attention in recent years. In this article, the authors have reviewed the metabolism of protein in rumen, small intestine, big intestine, mammary gland and factors those affect their use in gastrointestinal, immunoreactive protein in milk and research outlook.
