摘　　要：液态蛋氨酸羟基类似物 (HMB)是一种有效的反刍动物用活性蛋氨酸源 ,具有提高产奶量、改善乳成分、促进脂肪代谢和降低饲料成本等多种作用。本文在综述 HMB瘤胃降解研究结果的基础上 ,对影响其降解率的有关因素进行了详细分析 。Liquid methionine hydroxy analog(MHA) is an efficient source of active methionine for ruminant, which has many function in raising milk yield, improving milk composition, stimulating adiposity tissue and decreasing feed cost in animal production. Based on the review of the research advance of rumen degration of MHA, Factors influencing rumen degradation of MHA were analyzed. Finally it was indicated that digesta flow rate was the main factor affecting MHA efficiency.
