不同牧草在肉羊瘤胃中的降解特性研究.

The study was to evaluate the degradation properties of DM and CP of different forages in rumen of ruminants. The rumen degradation characteristics of six common pastures were analyzed by using three Dorset mutton sheep with permanent rumen fistulas as experimental animals. The results showed that the rumen real-time degradation rate of DM and CP of alfalfa was significantly higher than that of other forages (P<0.05), and the rumen real-time degradation rate of DM and CP of Leymus chinensis was the lowest. The order of DM effective degradation rate of different pastures was alfalfa > Satawang > oat grass > Foxtail> elephant grass > Leymus chinensis, and the order of CP effective degradation rate was alfalfa > Satawang > elephant grass = oat grass > Foxtail > Leymus chinensis. The study indicates that the degradation rate of the legumes alfalfa and Satawang in rumen is higher than that of elephant grass, oat grass, Foxtail and Leymus chinensis. [ABSTRACT FROM AUTHOR]
