Effects of NSP Enzyme Preparation and Dietary Fiber on the True Ether Extract Digestibility of Geese
In order to investigate the effect of dietary fiber and NSP (non-starch polysaccharides) enzyme preparation on the true ether extract digestibility of geese, Eight diet treatments were made up of 4 levels of dietary crude fiber (3.00%, 5.67%, 8.33%, 11.00%) and 4 levels of NSP enzyme preparation (0, 0.133%, 0.267%, 0.400%), according to U_8(8~2) of uniform design experiment method. A total of 45 (LangdexHuoyan) crossbred male geese (42 days of age) were randomly allotted to 9 groups of 5 replicates of 1 goose each. One group was used to evaluate endogenous ether extract, and the others were used for metabolism experiment by the way of TME respectively. The results suggested that true ether extract digestibility showed a quadratic curve pattern, in which there was the maximum when dietary fiber levels ranged from 3% to 11%. True ether extract digestibility increased the maximum (64.03%), when the levels of crude fiber was 4.63%. Addition level of NSP enzyme preparation was in the range from 0% to 0.40%, True ether extract digestibility showed a quadratic curve pattern. When dietary crude fiber level was 3.00%, and NSP enzyme preparation level was 0.33%, True ether extract digestibility gained the maximum (70.86%). True ether extract digestibility could get maximum value (72.79%), when the dietary fiber is 5.27% and NSP enzyme preparation is 0.35%.
