摘要 在高精料日粮条件下,以4头装有永久性瘤胃瘘管的本地山羊为试验动物,采用4×4拉丁方设计,研究酵母培养物对山羊瘤胃液动态发酵特性的影响。结果表明:日粮中添加酵母培养物可显著提高瘤胃液pH值,降低瘤胃液氨氮和乳酸浓度。6h时,30和40g/d试验组pH值分别较对照组提高0.29(P<0.05)和0.30(P<0.05);2h时,20、30和40g/d试验组氨氮浓度分别较对照组降低6.11%(P<0.05)、10.48%(P<0.05)和12.63%(P<0.05)。酵母培养物提高了瘤胃总挥发性脂肪酸(TVFA)浓度,4h时,20g/d试验组TVFA浓度较对照组提高21%(P<0.05);18h时,30g/d试验组TVFA浓度较对照组提高28%(P<0.05)。
