摘　　要：为探究不同浓度大蒜素对绵羯羊瘤胃发酵指标及甲烷产量的影响,试验选取6只体况良好,体重相近(28±1.0 kg),安装永久性瘤胃瘘管的绵羯羊,采用体外采气法,以基础日粮为底物,分别在基础日粮中添加大蒜素100、300和500 mg,筛选出最佳添加量。试验结果表明:饲料中添加不同浓度大蒜素对体外发酵pH值无显著影响(P>0.05);添加大蒜素100、300和500 mg均显著提高了体外培养液中BCP(P<0.05)、氨态氮(P<0.05)和丙酸(P<0.05)浓度,显著降低了乙酸浓度(P<0.05)和乙酸/丙酸(P<0.05);并对甲烷产量具有显著的抑制作用(P<0.05)。因此,添加300 mg大蒜素对上述指标影响最大。In order to explore the effect of different concentrations of allicin on the rumen fermentation index and methane production of sheep,six sheep with good body condition and similar body weight(28±1.0 kg)with permanent rumen fistula were selected for the experiment,the basal diet was taken as the substrate,adding allicin 100,300 and 500 mg respectively,and the best addition amount was screened.The test results showed that the addition of different concentrations of allicin to the feed had no significant effect on the pH value of fermentation in vitro(P>0.05);the addition of allicin 100,300 and 500 mg significantly increased the BCP(P<0.05),ammonia state in the in vitro culture medium Nitrogen(P<0.05)and propionic acid(P<0.05)concentrations,significantly reduced acetic acid concentration(P<0.05)and acetic acid/propionic acid(P<0.05);and significantly inhibited methane production(P<0.05).Adding 300 mg allicin had the greatest effect on the above indicators.
