两种饲料添加剂对羔羊育肥效果的影响

Effect of two different feed additives on the lambs fattening

选择德国美利奴×小尾寒羊杂交F1羔羊51只,按同质原则分为3组,每组17只.研究同一营养水平下,添加碳酸氢钠和益康"XP"的日粮短期育肥羔羊的效果.结果表明:碳酸氢钠组和益康组试羊比对照组试羊平均日增重分别提高了16.33 g和5.00 g.从利润来看,碳酸氢钠组最高,益康组次之,对照组最低.

Fifty-one crossed lambs（3 months old） of German mutton merino and Small-tail Han sheep were divided into three groups to investigate the effects of diet added with sodium bicarbonate and yeast culture XP on lamb short-term fattening,normal diet（as the control）,normal diet with sodium bicarbonate（A1） and normal diet with yeast culture XP（A2）.The results demonstrated that the average daily gain of A1 and A2 increased 16.33 g and 5.00 g respectively than control group,while all groups had no significant difference（P〉0.05）.From view of profits,A1 group and A2 group were greater than control group.It suggested that diet with sodium bicarbonate and yeast culture XP had a beneficial effect on lamb short-term fattening,and economic benefits were increased significantly.
