【摘要】 960只1日龄双鬼头肉鸭用于研究特威宝TMSSF在肉鸭日粮中的应用效果。试验结果表明,日粮类型和特威宝TMSSF对肉鸭的生长性能没有显著影响,但在玉米-豆粕型日粮中添加200PU/kg特威宝TMSSF以及在玉米-小麦-豆粕型日粮中添加300PU/kg特威宝TMSSF有提高肉鸭日增重和改善饲料转化率的趋势,玉米-豆粕型日粮中添加特威宝TMSSF可提高胫骨灰分含量。日粮类型和特威宝TMSSF对49日龄肉鸭的胫骨灰分中钙磷含量无显著影响,但在玉米-豆粕型日粮中添加特威宝TMSSF有提高胫骨钙含量的趋势。研究说明在肉鸭日粮中添加特威宝TMSSF可以提高肉鸭的养分利用效率,提高养鸭的经济效益。更多还原

【Abstract】 960 one-day-old Shuangguitou meat ducklings were used to study the efficacy of applying Allzyme SSF in meat duck diets. The results showed that diet type and Allzyme SSF had no significant effect on growth performance of duck,but 200 PU/kg Allzyme SSF supplementation in corn-soy diet and 300 PU/kg Allzyme SSF supplementation in corn-wheat-soy diet had a trend to improve feed conversion ratio and increase average weight gain. The addition of Allzyme SSF into corn-soy diet could increase tibia ash content. Basal diet type and Allzyme SSF supplementation had no significant effect on the P and Ca contents in tibias of 49-day-old ducklings,but Allzyme SSF supplementation in corn-soy diet had a trend to increase tibia Ca. The study suggested that Allzyme SSF supplementation in duckling diets may improve nutrient utilization and enhance ultimate profit of duckling production.更多还原
