| 摘 要： | 选用安装瘤胃瘘管的杂交绵羊(东北半细毛羊×小尾寒羊)4只,通过4×4拉丁方设计,系统研究了饲喂硼砂对DM,CP,ADF和NDF降解率及日粮外排速度的影响。结果表明,培养24h,饲喂硼砂提高了DM降解率(P<0.05);饲喂硼砂对CP降解率未产生影响;培养6h,2g·kg-1日粮硼砂组的ADF降解率显著高于对照组(P<0.05)。饲喂硼砂对日粮外流速度未产生影响。

| Abstract: | Four cannulated sheep were used in a 4×4 Latin square design to evaluate the effect of the 1 or 2 g·kg-1 diet of borax on outflow rate of diet and degradability of DM,NDF,ADF and CP in the rumen. Borax increased DM degradability for 24 h incubation(P <0.05). CP degradability was unaffected by borax. Borax in 2 g·kg-1 diet increased ADF degradability for 6 h incubation(P <0.05). Outflow rate of diet was unaffected by borax. |
