研究山羊瘤胃内放入装有不同种类牧草的尼龙袋后，瘤胃挥发性脂肪酸浓度的动态变化规律。选用带有瘤胃瘘管的山羊为实验动物，结合尼龙袋法测定3类牧草在山羊瘤胃中的挥发性脂肪酸浓度。结果表明，添加装有不同牧草的尼龙袋后，山羊瘤胃乙酸、丙酸、丁酸、总挥发性脂肪酸（TVFA）浓度及乙酸/丙酸值均呈先上升后下降的规律，并在4 h达到峰值，其中乙酸浓度约为70.49%、丙酸浓度约为15.38%，瘤胃的发酵类型总体上偏向于乙酸-丙酸型，3类牧草均适用于山羊的科学饲养。由此可见，添加装有不同种类牧草的尼龙袋均会对山羊瘤胃挥发性脂肪酸产生影响，其原因主要与原料的蛋白质含量有关。

The change trend of volatile fatty acid (VFA) in goat rumen after putting nylon bags with different kinds of forage was studied. The concentration of VFA in goat rumen after putting nylon bags with three kinds of forage was determined by using nylon bag method. The results were as follows: after the roughages with nylon bags were put in rumen, the concentration of acetate, propionate, butyrate, total volatile fatty acid (TVFA) concentration, and the ratio of acetate to propionate all firstly increased and then decreased,and reached the peak at four hours, among them the concentrations of acetate and propionate were 70.49%and 15.38%;the fermentation type of rumen totally leaned to acetate-propionate type;the three kinds of forage all contributed to feed goat. So the nylon bags with feedstuffs could affect the volatile VFA concentration, and it is in connection with the protein content of feedstuffs.
