为探明全混合日粮饲喂技术在西门塔尔牛与新疆褐牛杂交一代牛（西杂牛）育肥期的使用效果，选择健康无病、年龄22～24月龄、体重（380±10）kg 的西杂牛40头进行150 d 全混合日粮及传统饲喂方式（对照）的饲喂试验。结果表明：饲喂全混合日粮的西杂牛日增重为1010．2 g，显著高于对照组（P ＜0．05）；消化系统发病率极显著低于对照组（P ＜0．01），饲料报酬两组间差异不显著（P ＞0．05）；饲喂全混合日粮的胴体重为329．6 kg，显著高于对照组（P ＜0．05）；屠宰率、净肉率、眼肌面积、肉色和大理石纹间差异不显著。

In order to investigate the effect of TMR on meat cattle in fattening period,40 cattle hybridized by Simmental and Xijiang He bovine,which were healthy,22~24 months old,and (380±10) kg weight,were chosen to compare the difference of TMR and traditional feeding method by measuring the growth performance and carcass characteristics during fattening period.The results showed that the average daily gain of treatment group was 1 010.2 g,higher than the control (P < 0.05 ),and the morbidity rate was significantly lower than the control (P <0.01),but there were no significant difference on feed conversion between them(P >0.05).Moreover,the carcass weight of treatment group was 329.6 kg,significantly higher than the control (P < 0.05 ),but there were no significant difference on the dressing percentage,net beef percentage,rib-eye area,meat color and marbling score between them(P >0.05).
