【摘要】 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。更多还原

【Abstract】 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.更多还原
