稻谷添加专用酶替代部分玉米对肉鸭生长及物质代谢的影响

本试验采用对照试验设计,以常规的玉米-豆粕为主(不含稻谷)的日粮为对照组,在对照日粮基础上用20%的稻谷替代20%的玉米并添加稻谷专用酶制剂的日粮为试验组,以肉鸭为试验对象进行为期50天的比较研究。结果表明,相对与对照组,试验组的肉鸭的生长性能、养分利用率差异不显著(P)0.05,可明显提高经济效益;试验组的日粮CF(粗纤维)表观消化率提高了12.6%(P<0.05),DM(干物质)、CP(粗蛋白)、EE(粗脂肪)的表观消化率分别降低了2.62%、1.88%、2.59%(P)0.05),说明用稻谷代替鸭日粮中的部分玉米是可行的。

The trial adopting the design of comparion, the control group ,dietary composed of corn and bean mainly, the trial group, using 20% paddy and adding specical enzyme to substitute 20% corn on the foundation of the control,researches the difference of the growth and nutrition metabolize of ducks for 50days. As a result express that opposite with matched control, the growth function, the rate of the nutrient utilization does not show the dinstinct （P〈0.05）, can raise the economic benifit obviously;The food CF（ crude fiber） form view digest rate of day that experiments raised 12.6%（P〈0.05）, the rate of view digest of the DM（dry material）, CP（crude protein）, EE（ ether extract） lowered 2.62%,1.88%,2.59%（P〉0.05） respectively, explains that replace the duck with paddy for day parts of corn of feed is viable.
