摘要 研究了饲料中添加不同水平复合酶制剂(0、0.1%、0.3%、0.5%)对断奶仔猪生长发育及饲料利用率的影响。结果表明,饲料中添加复合酶制剂使断奶35~50 d仔猪的日增体质量提高26.52%~30.61%(P〈0.05),采食量降低1.5%~15.35%;使断奶35~65 d仔猪的日增体质量提高1.86%~13%,采食量降低4.6%~10.97%。复合酶制剂在仔猪饲料中的最适添加量为0.3%。 The different levels (0, 0.1%, 0.3% and 0.5%) of compound enzyme were added in diets to study its effects on the piglet growth-development and feed conversion rate. The results showed that the compound enzyme added in diets increased the daily gain by 26.52%~30.61%(P〈0.05)and decreased feed intake by 1.5%~15.35% in the 35~50days weaning group ; but the daily gain was increased by 1.86%~13% and the feed intake was decreased by 4.6%~10.97% in 35~65days weaning group. The suitable adding level should be 0.3%.
