摘　　要：采用体外消化试验方法研究在鹅基础日粮中分别添加0.2%和0.4%的NSP酶制剂对粗蛋白质、粗纤维、粗脂肪、粗灰分、干物质和氨基酸的体外消化率及还原糖生成量的影响。结果显示:0.2%与0.4%的NSP酶对还原糖生成量提高幅度分别为16.18%与23.93%(P<0.05);对粗纤维体外消化率提高幅度分别为23.87%、28.73%(P<0.05),对粗蛋白质体外消化率提高幅度分别为4.50%、5.03%(P<0.05),对干物质体外消化率提高幅度分别为6.14%、9.44%(P<0.05),对粗灰分体外消化率提高幅度分别为1.85%(P>0.05)、6.84%(P<0.05),对粗脂肪体外消化率无显著影响(P>0.05);对氨基酸体外消化率结果显示:对异亮氨酸体外消化率提高幅度分别为7.41%、10.69%(P<0.05),对谷氨酸体外消化率提高幅度分别为6.98%、10.25%(P<0.05),而对其它氨基酸体外消化率无显著影响(P>0.05)。The effects of 0.2% and 0.4% NSP enzyme preparations added into the basal diets for gooses on in--vitro digestibility of crude protein, crude fiber, crude fat, crude ash, dry matter and produced amount of reducing sugar were studied through in--vitro digestion test. The results showed that 0.2 % and 0.4 % NSP enzymes could increase the produced amount of reducing sugar by 16.18%/00 and 23.93% （P〈0.05） respectively, the in--vitro digestibility of crude fiber by 23. 870/00 and 28.73% （P〈0.05） respectively, the in--vitro digestibility of crude protein by 4.50% and 5.03% respectively （P〈0.05）, the in--vitro digestibility of dry matter by 6.14% and 9.44% respectively （P〈0.05）, the in--vitro digestibility of crude ash by 1.85% （P 〈0.05） and 6.84% （P〈0.05） respectively, and the in--vitro digestibility of crude fat was not significantly effected. The results of in--vitro digesti- bility of amino acids indicated that 0.2 % and 0.4 % NSP enzymes increased the in--vitro digestibility of isoleucine by 7.41% and 10. 69% （P〈0. 05） respectively and the in--vitro digestibility of glutamic acid by 6. 98% and 10.25 % （P〈0.05） respectively, but effected the in--vitro digestibility of other amino acids not significantly.
