摘　　要：以多浪羊为瘤胃液供体,研究葡萄皮添加量分别为5%、10%、15%、20%、25%、30%对高蛋白日粮体外产气量的影响。通过检测累积产气量(GP)、发酵参数(a、b、c)、p H值和有机物消化率(OMD),评定葡萄皮作为饲料资源的营养价值及适宜添加量。结果表明,不同添加量葡萄皮的产气量均随时间延长而增加,且显著高于高蛋白日粮组(P<0.05)。至发酵72 h结束,高蛋白日粮中以葡萄皮添加量为20%(90.50 m L,72 h)的产气量最高;葡萄皮添加量为15%(85.67 m L,72 h)次之;葡萄皮添加量为5%(76.00 m L,72 h)最低。发酵结束时,高蛋白日粮中以葡萄皮添加量为10%的有机物消化率最高,葡萄皮添加量为25%和30%时次之,添加量为15%时最低。综上提示,葡萄皮添加量为20%时,高蛋白日粮的产气量较高,有机物消化率也相对较高。In present study, the rumen fluid of Duolang Sheep was used as donator to assess the different additive amount（5%,10%, 15%, 20%, 25% and 30%） of grape skin on gas production of protein-enriched diet in vitro. The gas production（GP）,fermentation parameter（a, b, c）, p H values and organic matter digestibility（OMD） were determined to evaluate the nutritional value of grape skin as a feed resource and its optimal additive amount. The results revealed that the GP of the protein-enriched diet added with different amount of grape skin was increased with the extension of fermentation time, and it was significantly higher than that of control group（P0.05）. After fermentation for 72 hours, the highest GP was observed in protein-enriched diet added with 20% grape skin（90.50 m L, 72 h）, followed by 15%（85.67 m L, 72 h）. The lowest GP was observed in protein-enriched diet added with 5% grape skin（76.00 m L, 72 h）. At the end of the fermentation test, the highest OMD was obtained when the additive amount of grape skin was 10%, followed by 25% and 30%. The lowest OMD was obtained when the additive amount was 15%. The combined data showed that when 20% grape skin was added in protein-enriched diet, the relatively higher GP and OMD were obtained.
