【Abstract】 There were three groups of layer (i. e. control group,CE 1 and CE 2 groups). The control group was fed on the dietary without enzyme preparation. The groups CE 1 and CE 2 were fed on the dietary based on corn and soybean cake added with 0.1% enzyme preparation from different formulas (E 1 and E 2 ) for seven weeks. The results showed that the laying rate ,egg weight and laying yield of the treatment groups increased remarkably and the energy utilization and protein digestibility were improved greatly, in which the effects of the group CE 1 were best.更多还原
