摘要
在30～50kg生长猪阶段,保持日粮结构不变,在日粮中添加啤酒糟8%12%、16%,同时添加含NSP酶的复合酶制剂,以探讨使用经济用量的酶制剂时生长猪日粮中啤酒糟的适宜添加水平。试验结果表明,在生长育肥猪日粮中加0.05%复合酶时可添加的12%干啤酒糟,生产性能不下降;酶制剂对于高NSP日粮有一定的改善作用。
crossbred growing pigsDuroc×Landrice×Yorkshire with weight (30±1) kg were divided randomly into twenty groups four pigs in each group were put in a pen. These pigs were fed three different diet with NSP enzyme preparation, which contained 8%? 12%? 16% brewer's dried grain respectively. The results indicated that adding 12% brewer's dried grain into the diet coundn't decrease the pig's productive perfomance under the condition of adding 0.05% enzyme preparation.
