摘  要：
本试验研究非淀粉多糖(NSP)酶与日粮纤维对日粮真代谢能的影响并考察日粮纤维与NSP酶的真代谢能当量关系,采用U8(82)拟水平二次均匀设计,将生长鹅日粮粗纤维分为:3.00%、5.67%、8.33%、11.00%4个水平,NSP酶分为:0%、0.133%、0.267%、0.400%4个水平,两因素组成8个日粮处理;选择42日龄、体质健壮的二元杂交(朗德鹅×豁眼鹅)公鹅45只,随机均分为9组,每组5只,每个重复1只,其中1组用于内源能量测定,其他8组对应8个日粮处理,进行代谢试验,用真代谢能法测定日粮真代谢能。结果表明:日粮粗纤维水平在3.00%～11.00%范围内,日粮真代谢能呈二次曲线规律,存在极大值;日粮真代谢能达极大值(11.79MJ/kg)的粗纤维水平为5.50%;NSP酶在0%～0.40%范围内,日粮真代谢能呈二次曲线规律,存在极大值;当日粮粗纤维水平为3.00%时,日粮真代谢能达极大值(11.96MJ/kg)的NSP酶水平为0.31%;日粮粗纤维的能量当量为-17.45～9.09MJ/kg;NSP酶的能量当量为152.50～338.46MJ/kg。

摘  要：
The effect of NSP enzymes and dietary fiber on true metabolizable energy and the energy equivalent between them were investigated.Eight diet treatments were treated with 4 levels of dietary crude fiber (3.00 % ,5.67 % , 8.33 %,11.00 %)and 4 levels of NSP enzymes (0 %,0.133 %,0.267 %,0.400 %),according to U8 (82) uniform design experiment method.Forty five 42-day aged growing male geese produced by a cross between Landes geese and Huoyan geese were randomly divided into 9 groups,5 replicates of 1 goose each.One group was used to test endogenous energy,the others were used for metabolism experiment by TME.The result showed that dietary fiber levels ranged from 3 % to 11 %, true metabolizable energy showed a quadratic curve pattern,and there was maximum.When the levels of crude fibre was 5.50 %,true metabolizable energy gained the maximum(11.79 MJ/kg).NSP enzymes addition ranged from 0 % to 0.40 %, true metabolizable energy showed a quadratic curve pattern.When dietary crude fiber level was 3.00 %,and NSP enzymes was 0.31 %,true metabolizable energy gained the maximum (11.96 MJ/kg).Energy equivalent of dietary crude fiber and NSP enzymes were -17.45 ～ 9.09 MJ/kg and 152.50 ～ 338.46 MJ/kg,respectively.
