当反应体系中存在水时，有特戊酸生成。表明反应中2，2，4-三甲基戊烷首先发生β-断裂反应，生成叔丁基正碳离子和异丁烯。

The results show that there were no significant differences among the four forage rations in rumen pH, the concentrations of total volatile fatty acids, acetate, propionate, the ratios of acetate to propionate, butyrate, isobutyrate and valerate（P﹥0.05）. Only in 11:30, the concentrations of isovalerate caused by ration A and B were significantly higher than the other two rations(P﹤0.05).The milk yield caused by the ration C was significantly lower than the others (P﹤0.05). However, there were also no significantly differences among these four rations in the DM, fat, sugar, protein and scc of the milk. The milk fat and sugar of ration B and C were higher than ration A and D in number as well.
