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(jù)牧草的基本營養(yǎng)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(yǎng)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(fā)明涉及一種反芻動物的蛋白質營養(yǎng)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(yǎng)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(tài)系統(tǒng)，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(xié)同又制約的動態(tài)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(yè)。)

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(tài)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(qū)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(jù)反芻動物蛋白質、脂肪營養(yǎng)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(yǎng)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。)
