摘　　要：采用人工瘤胃法研究了豆油和棉籽油中亚油酸等多聚不饱和脂肪酸在瘤胃微生物作用下的氢化中间产物trans11油酸变化规律以及对瘤胃发酵的影响。结果表明添加豆油和棉籽油使trans11油酸得到累积,其中4%处理组显著高于对照组(P<0.05)。处理组的总挥发酸浓度均高于对照组,棉籽油处理组与对照组差异达到显著(P<0.05)。处理组NH3N浓度均高于对照组,2%豆油、2%棉籽油和4%棉籽油处理组与对照组差异达到显著(P<0.05)。The effects of polyunsaturated fatty acid from soybean oil and cottenseed oil on the accumulation of Trans vaccenic acid (TVA) -biohydrogenation of ruminal microbes and rumen fermentation were researched with artificial rumen.Results indicated that TVA was accumulated with treatments of soybean oil and cottenseed oil, especially 4% treatments were abstractly higher than control(P<0.05).The concentrations of total volatile fatty acid (TVFA) of all treatments were higher than control, cottenseed oil treatments were obviously higher than control(P<0.05).The concentrations of NH_3-N were also higher than control,treatments of 2%soybean oil ,2%cottenseed oil and 4%cottenseed oil were obviously higher than control(P<0.05).
