木瓜蛋白酶和苜蓿对断奶仔猪生长性能的影响

Effects of papain and alfalfa on growth performance in weaned piglets

选取杜×长×大三元杂断奶仔猪171头作为实验动物,研究木瓜蛋白酶的添加和苜蓿替代部分豆粕后对断奶仔猪腹泻、生产性能的影响。结果表明:添加木瓜蛋白酶后对仔猪的生长有促进作用,平均日采食量增加2.7%、平均日增重提高2.56%、料重比分别提高2.7%、2.56%和降低1.6%。添加木瓜蛋白酶并用苜蓿替代5%的豆粕对仔猪的生长也有促进作用,平均日采食量增加10.8%、平均日增重提高7.69%、料重比降低1.03%。

171 cross breeding pigs were selected as experimental animals for studying the influence of adding papain and alfalfa （replacing part of soybean） on production performance and diarrhea of weaned piglets. The results showed that adding papain could promote piglets＇ growth. The average daily feed intake increased 2.7%, the average daily gain increased 2.56% and feed/gain ratio decreased 1.6%. Adding papain and alfalfa （replacing 5% soybean） could promote the growth of piglets. The average daily feed intake increased 10.8%, the average daily gain increased 7.69% and feed/gain ratio decreased 1.03%.
