肉用公羊和多胎母羊杂交后代不同营养水平育肥试验

The fattening Effect of Descendant’s with the Meat Ram and the Fecundity Ewe

利用高腿萨福克的生长发育优势和湖羊的多胎性进行杂交组合,对所产后代用不同的育肥标准分四组进行早期断奶育肥。经测定第一组的日增重为253.2g,第二组的日增重为266.3g,第三组的日增重为236.7g,第四组的日增重为237.6g,其中第二组的日增重与其他组差异极显著(P<0.01);各组的体尺变化也不同,生长发育快的组,体尺增加的也快。通过试验筛选出了育肥方法的最佳组,第二组的料肉比最佳,从而为合理进行羔羊舍饲育肥提供依据。
