According to the basic nutrient characteristic of forage grass, this article generalize the achievement that utilize forage grass in ruminant and improve nutrient value of forage grass.(根據牧草的基本營養價值特性，綜合了近年來人們對反芻家畜利用牧草及提高牧草營養價值的生物學研究成果。)

The present invention relates to nourishing protein additive for ruminant, and is especially one kind of nourishing rumen-passing protected amino acid additive for ruminant and its production process.(本發明涉及一種反芻動物的蛋白質營養添加劑及生產該添加劑的方法，特別是涉及反芻動物的過瘤胃保護性氨基酸營養添加劑及生產該添加劑的方法。)

The products of ruminant feed and cattle or sheep-derived feed from the enterprises and farms of 7 districts in Shaanxi province were detected by real-time PCR.(實時PCR對陜西省7個地市生產、經營和使用的反芻動物飼料產品和動物源性飼料產品（原料）進行了牛羊源成分檢測調查。)

The measurement technique of methane emissions from ruminant livestock ushg SF6tracer method was described, which included the basic principle, instrument preparation and the experiment condition.(詳細描述了用六氟化硫示蹤法測定反芻動物甲烷排放的技術，包括基本原理、儀器準備和測試條件。)

The rumen of ruminant was a complex micro ecosystem, which there was a dynamic balance that was both collaborative and constraints between rumen microorganisms and host, and also between microbes.(反芻動物瘤胃是一個復雜的微生態系統，瘤胃微生物與宿主之間、微生物與微生物之間處于一種既協同又制約的動態平衡關系。)

DDGS was first used in ruminant production. In recent years, there were also many reports related DDGS used in swine, chickens and other single stomach animal production industry.(DDGS最先用于反芻動物生產中，近年來，也有很多報道將DDGS用于豬、雞等單胃動物生產行業。)

Effects of dietary fiber on intestinal mucosal morphology and epithelial cell turnover, mechanisms and digestive functions in non-ruminant animals were reviewed.(本文綜述了日糧纖維對非反芻動物腸黏膜形態和上皮細胞更新的影響及其作用機理和對動物消化功能的影響。)

These technologies have proven successful in studying the rumen microflora, giving a better understanding of ruminant microflora populations, their functions and the influence of various factors.(這些技術證明是成功的研究瘤胃微生物區系，給予更好地了解反芻動物的微生物種群、職務和各種因素的影響。)

According to the characteristic of the ruminant protein and fat metabolism, Detailed explaining the influence of protein and fat level on the digestibility of crude fiber in ruminant diet.(本文根據反芻動物蛋白質、脂肪營養代謝的特點，較為詳盡的闡述了日糧中蛋白質和脂肪水平對粗纖維消化率的影響。)

Through to ruminant livestock nutrition physiology the understanding, elaborated how enhances the feed protein and the nonprotein nitrogen in ruminant livestock production the use efficiency.(通過對反芻家畜營養生理的認識，闡述如何提高飼料蛋白質和非蛋白氮在反芻家畜生產中的利用效率。)
