摘要
选用3月龄羔羊80只,随机分为4组,在基础日粮中加3个水平剂量的蛋氨酸锌0.2、0.4、0.6 g/(只.日)饲喂50 d,观察蛋氨酸锌对羔羊增重及生长发育的影响。试验表明:蛋氨酸锌的添加水平为0.2 g/(只.日)时,育肥羔羊的增重、日增重、料肉比、钙、磷、粗蛋白的表观消化率最高,即羔羊饲料中0.2 g/(只.日)剂量的蛋氨酸锌,可使育肥羔羊得到最佳的生长效果。
Eighty plateau-type Tibetan sheep were divided randomly into 3 experimental groups and 1 control group（20 sheep in each group）.Zinc methionine were supplemented in three groups diets by 0.6 g,0.4 g,0.2 g respectively in the every day.The results showed that the group with 0.2 g zinc methionine had the highest total gain,average daily gain（ADG）,feed conversion rate and also the highest apparent digestibility for Ca,P,CP etc.It indicates that supplementing 0.2 g zinc methionine can improve the gain and profits of fattening sheep significantly,which is the proper dose in diet.
