摘要
选用12只2周岁体况良好,体重35 kg的内蒙古半细毛羯羊,随机分成4组,每组3头,分别饲喂4种不同水平苜蓿皂甙的日粮(0、8、16、32 g/d)。试验结果表明,在试验期内,苜蓿皂甙对绵羊氮平衡及生产性能有影响。当苜蓿皂甙添加量为8g/d时,氮沉积及日增重最高。
Twelve two years old inner mongolian fine wool semi- wethers with 35 kg body weight ,divided into 4 groups of 3 were used to study the effects of 4 levels of alfalfa saponin on nitrogen balance and performance . The results showed that when the levels of alfalfa saponins was 8 g/d, the utilization of nitrogen and daily body gain were the highest.
