高纤维基础日粮添加非淀粉多糖酶制剂对生长鹅生产性能及内分泌的影响

Effects of adding non-starch polysacharide (NSP) enzymes to high dietary fiber-based diets on production performance and incretion in growing geese

选择300只29日龄生长鹅进行28 d的饲养试验,研究了在高纤维基础日粮(粗纤维11.02%)中分别添加0.2%和0.4%的非淀粉多糖(NSP)酶制剂对生长鹅生产性能及内分泌的影响。对生产性能的研究结果显示:0.2%与0.4%的NSP酶制剂对平均日增重提高幅度分别为14.82%与19.69%(P<0.05),对饲料转化率提高幅度分别为13.27%与19.93%(P<0.05),对平均日采食量无显著影响(P>0.05)。对内分泌指标的研究结果显示:0.2%与0.4%的NSP酶制剂显著提高了血糖、总蛋白、T3和IGF-Ⅰ(P>0.05),而总胆固醇、甘油三酯、尿酸、谷丙转氨酶、谷草转氨酶、碱性磷酸酶、胰高血糖素、胰岛素、TSH、GH、T4均无显著影响(P>0.05)。

Three hundred 29-day aged growing geese were used to study the effects of 28-day high dietary fiber-based diets containing different NSP enzymes levels(0,0.20%,0.40%) on their production performance,metabolic hormone and blood biochemical index.The results showed that in the conditions of both supplementations with 0.2% and 0.4% NSP enzymes,ADG were significantly(P<0.05)enhanced by 13.27% and 19.93% respectively,and FCR were significantly(P<0.05) enhanced by 13.27% and 19.93% respectively;but ADFI was...
