| 摘 要： | 采用双外流连续培养系统,连续灌注酪蛋白动态模拟氮源释放,研究瘤胃能氮同步化释放对微生物蛋白产量的影响.结果表明,酪蛋白灌注数量对OM和ADF降解率的影响显著(P<0.001),对NDF降解率的影响显著(P<0.05).随酪蛋白灌注数量的增加,OM、NDF和ADF降解率均有增加趋势.酪蛋白灌注量对氮降解数量、可降解有机物利用效率和降解氮利用效率影响极显著(P<0.001),对微生物氮产量影响显著(P<0.05).MN/RDN=0.9921-0.2095 Ln(RDN/DOM),(n=27,R2=0.6058).

| Abstract: | The influence of synchronizing the release of nitrogen by rumen to the yield of microbial protein was studied by using dynamic simulation of nitrogen released by infusing casein in a dual culture of continuous outflow of artificial rumen.The result indicates that the quantity of infused casein had very significant influence to the digesyibilities of OM and ADF(P<0.001),significant influence to the digestyibilities of NDF(P<0.001).The quantity of infused casein had strong significant influence to the utiliza... |
