摘要
本研究主要针对湖羊规模化饲养后断奶羔羊生长发育不良状况,设计三种不同日粮配方进行60d补饲试验。结果表明,无论从日增重,料肉比还是投入与产出之比来看,均以配方 能量13.38MJ/kg和粗蛋白13.88%最佳;而配方 能量13.37MJ/kg,粗蛋白15.55%和配方 能量12.88MJ/kg,粗蛋白17.75%次之。
A feeding experiment was carried out for 60 days to investigate the effect of three different diets on growth of weaned lambs in the Hu Sheep and its crossbreed in the field condition. The results showed that diet Ⅰ containing 13.38 MJ/kg of energy and 13.88% of crude protein was the best, in comparison with diet Ⅱ containing 13.37 MJ/kg of energy and 15.55% crude protein and diet Ⅲ containing 12.88 MJ/kg of energy and 17.75% crude protein, from the view of daily gain, ratio of feed to gain, and ratio of input to output.
