多浪羔羊早期断奶效果研究

Study on Effect of Early Weaning of DuoLang Lamb

通过对多浪羔羊不同日龄断奶时的断奶重、日增重量进行了观察。结果表明:在同等饲养管理条件下,60日龄羔羊的日增重量均大于70、80、90日龄羔羊的日增重量,差异极显著(P<0.01),70日龄羔羊的日增量重大于90日龄羔羊的日增重量,差异极显著(P<0.01);90日龄羔羊的断奶重均大于60、70、80日龄羔羊的断奶重,差异显著(P<0.05);90日龄羔羊的增重量大于60日龄的增重量,差异极显著(P<0.01),也大于70日龄的增重量,差异显著(P<0.05);其余各组之间的断奶体重、日增重量、增重量差异不显著(P>0.05)。

The weaning weight and daily gain of different days for DuoLang lamb were observed in the same feeding conditions.The results showed that the average daily gain of 60 d lambs were higher than that of 70,80,90 d lambs,the differences were very significant（P0.01）;The average daily gain of 70 d lambs were higher than that of 90 d lambs,the differences were very significant（P0.01）;The average weaning weight of 90 d lambs were higher than that of 60,70,80 d lambs,the differences were significant（P0.05）;The average weight gain of 90 d lambs were higher than that of 60 d lambs,the differences were very significant（P0.01）,also higher than that of 70 d lambs,the differences were significant（P0.05）;The average weaning weight,average daily gain and average weight gain were no significant differences among other groups（P0.05）.
