| 摘 要： | 本文用瘤胃持续模拟装置研究了精粗比为７：３、１：１和３：７时对日粮有机物、中洗纤维和酸洗纤维的降解、蛋白质的转化和微生物合成效率的影响。结果表明，精粗比不影响瘤胃微生物对可发酵能的利用效率（Ｐ〉０．０５），但是显著影响瘤胃微生物对可降解氮的利用效率（Ｐ〈０．０５）；最后探讨了瘤胃内可降解氮和可发酵能与微生物氮合成量之间的定量模型。

| Abstract: | The conversion efficiencies of fermented OM(FOM)and degradable N(RDN)from three diets with concentrate to roughage ration of 7:3,1:1 and 3:7 to rumenmicrobes were studied witb rumen simulation instrument herein,The results show thatdifferent ratio of concentrate to roughage has no significant effect on FOM utilizationefficiency(P>0.05), but really has significant effect on RDN utilization efficiency(P<0.05).The model among microbial nitrogen synthesis,FOM and RDN was discussed. |
