摘要
研究选取了体重为20.0 kg左右的杜×长×大三元杂交猪24头,随机分为3组,每个处理组8头,分别饲喂不含酶制剂、含酶制剂Ⅰ、含酶制剂Ⅱ的3种日粮,饲养期为28 d。结果表明,酶种类齐全、酶活高的复合酶制剂,能够更有效地提高仔猪的生长性能,改善对饲料氮和磷的利用,降低粪便的排放污染,是未来高效新型环保饲料添加剂的发展趋势。
Pigs,weighing an average of 20.0 kg were randomly assigned to three dietary treatments,eight pigs with each pen.The groups were respectively fed with the three kinds of different diets which contained no compound enzyme preparation,compound enzyme preparation Ⅰ,compound enzyme preparation Ⅱ for 28 days.The results show that compound enzyme preparation with full range and high enzyme activity,can not only improve effectively the growth performance and ameliorate utilization of nitrogen and phosphorus in feed,but also reduce pollution of pig manure.So compound enzyme preparation will be the development trend in the form of new efficient and environmental protection feed additive in the future.
