苜蓿草粉对生长猪生产性能和免疫功能的影响

The effect of alfalfa meal on the performance of growing pigs and immune function

试验选用体重约25 kg 的杜长大三元杂交猪60头,采用单因子实验设计,分为5组,每组3个重复,每个重复4头猪,分别在基础饲粮中添加0%、5%、10%、15%、20%的苜蓿草粉.结果表明:添加5%、10%苜蓿草粉可显著提高25～50 kg 生长猪的增重效果及饲料转化率(P<0.05),对淋巴细胞和 ANAE 阳性细胞也有明显的促进作用(P<0.05).

The selection weighs about 25 kg of three-way cross of Duroc pigs 60, a single-factor experimental design, divided into five groups, each with three repeat, repeat every four pigs, respectively, in the basic diet of adding 0 %, 5%, 10%, 15%, 20% the proportion of different alfalfa meal. The results show that： Add 5%, 10% alfalfa meal can significantly increase the growth of 25 to 50 kg weight gain effect of pig and feed conversion rate （P 〈0.05）, lymphocytes and ANAE positive cells there is an obvious role in promoting （P 〈0.05 ）.
