摘  要：
[目的]确定双低菜籽饼在育肥羔羊精料中的适宜添加量。[方法]选择120只50日龄藏羔羊,随机分为4组,分别饲喂双低菜籽饼添加量为50、100、150和200 g/kg且能量和蛋白水平一致的混合精饲料。试验期为120 d。[结果]精料中添加150 g/kg双低菜籽饼能显著提高羔羊的日增重(P<0.01)、饲料转化率和经济效益。精料中添加200 g/kg双低菜籽饼则明显降低羔羊的采食量和饲料转化率。各组间血清转氨酶活性和血清甲状腺素水平均差异不显著。[结论]育肥羔羊精料中双低菜籽饼的适宜添加量为150 g/kg。

摘  要：
[Objective] To determine the optimal supplement dosage of double-low rapeseed meal in concentrated feed of fattening lambs.[Method] A total of 120 Tibetan lambs at the age of 50 d were selected and divided randomly into four groups.The lambs in these four groups were fed with diets respectively supplemented the double-low rapeseed meal of 50,100,150 and 200 g/kg.Their diets had the same nutritional levels of energy and protein.The experimental period was 120 d.[Result] Daily gain,feed conservation ratio and economic benefits were largely increased in the lambs fed with diets supplemented the double-low rapeseed meal of 150 g/kg(Daily gain,P<0.01).However,the daily gain and feed conservation ratio were largely decreased in the lambs fed with diets supplemented the double-low rapeseed meal of 200 g/kg.Moreover,serum transaminase and thyroxine levels were not significant between the four groups.[Conclusion] The optimal supplement dosage of the double-low rapeseed meal is 150 g/kg in fattening lambs.
