摘要
试验选用 96头体重为 18.9± 2 .5kg的三元杂交 (北京黑×长白×杜洛克 )生长猪 ,随机分为 3个处理 ,处理1为玉米 -豆粕对照组 ;处理 2为用豌豆蛋白取代 2 5 %的基础日粮蛋白组 ;处理 3为用豌豆蛋白取代 5 0 %的基础日粮蛋白组。每个处理 8个重复 ,每个重复 4头猪 ,测定生长猪的生长性能。结果表明 ,试验前期用豌豆蛋白取代基础日粮的部分蛋白 ,可使生长猪的日增重和采食量均显著降低 (P <0 .0 5 ) ,而饲料增重比无明显变化。随着生长猪日龄增加 。
growing pigs with body weight 18.9± 2.5 kg were divided into three groups at random, 8 replications in each group and four pigs per replication. Group Ⅰ is a control one fed the diets with corn-soybean meal, group Ⅱ fed the diets with pea protein replacing 25% protein in the basic diets, and group Ⅲ fed the diets with pea protein replacing 50% protein. The results showed that the daily gain weight and feed intake of growing pigs fed the diets with pea protein replacing partial protein in basic diets were decreased greatly( P <0.05) in the early trial period, but the feed efficiency was not significantly changed. The effects of pea on the growing performace would be reduced gradually with the pig growth.
