互助八眉三元商品猪育肥前期饲料蛋白水平筛选

为探索互助八眉三元商品猪育肥前期饲料配方,在消化能水平为13MJ/kg前提下,日粮粗蛋白水平分别为14%(1^#)、16%(2^#)、18%(3^#)三个试验组。结果表明:3^#日增重与各试验组之间差异不显著,与对照组之间差异显著(P<0.05);料重比最小,与各组之间差异极显著(P<0.01);单位增重饲料成本最低,与2^#之间差异显著(P<0.05),与1^#、对照组之间差异极显著(P<0.01)。推荐八眉三元商品猪前期蛋白水平为18%,育肥效果最佳。

Screening of Feed Protein Levels of Huzhu Bamei Ternary Commercial Pigs in Early Fattening

In order to explore the pre-finishing feed formula of Huzhu Bamei ternary commercial pigs,the crude protein level of diets in test groups is 14%(1^#),16%(2^#),18%(3^#)respectively under the premise that the digestible energy level is 13 MJ/kg.The results showed that there is not significantly different between 3^#daily weight gain and other two experimental group,but there was significantly different between 3^#group and control group(P<0.05).the feed-to-weight ratio was the smallest,and there was a extremely significant(P<0.01).The weight gain feed cost has the lowest,which is significantly different from 2^#(P<0.05),and extremely significantly different from 1^#and the control group(P<0.01).It is recommended that the early protein level of Bamei ternary commercial pigs is 18%,and the fattening effect is the best.
