表面活性剂分为化学表面活性剂和生物表面活性剂两大类,非离子表面活性剂和生物表面活性剂作为新型反刍动物饲料添加剂,可通过改变瘤胃液乳化特性、瘤胃微生物种群数量、分泌酶活性、酶吸附能力和瘤胃发酵模式,来增强瘤胃微生物对粗饲料的降解能力,进而提高反刍动物生产性能。综述提出了表面活性剂在反刍动物瘤胃营养调控领域的研究重点。
錶麵活性劑分為化學錶麵活性劑和生物錶麵活性劑兩大類,非離子錶麵活性劑和生物錶麵活性劑作為新型反芻動物飼料添加劑,可通過改變瘤胃液乳化特性、瘤胃微生物種群數量、分泌酶活性、酶吸附能力和瘤胃髮酵模式,來增彊瘤胃微生物對粗飼料的降解能力,進而提高反芻動物生產性能。綜述提齣瞭錶麵活性劑在反芻動物瘤胃營養調控領域的研究重點。

The surfactants are divided into chemical surface active agent and biosurfactants.The nonionic surfactants and biosurfactants are accepted as the new type additives in the feed of ruminants.Through altering the emulsification of ruminal fluid,the number of ruminal microorganisms,the activity and adhesive ability of ruminal endogenous enzymes secreted by ruminal microbes,and fermentation pattern,they can effectively improve the degradability of roughages in the rumen and the productivity of ruminants.The preparation,purification,industrial production and nutritional mechanism of biosurfactants will be the focuses in the filed of ruminant nutrition.
