统糠在鹅饲料中的应用研究

在鹅饲料中加入不同比例的统糠以及用一定比例的统糠构成日粮并通过调节其能量和蛋白水平,观察其对日粮养分利用及鹅生产性的影响。用合浦鹅进行饲养试验和代谢试验,在试验一中测定不同比例统糠构成的日粮,在试验二中测定不同能量和蛋白水平对日粮养分利用效率和试鹅增重效果。结果表明,统糠在鹅饲料中占12.0%~20.0%,日粮代谢能在10.0~11.0MJ/kg,蛋白水平在14.0%~17.0%时,统糠及其构成的日粮有较好的养分利用效率,试验鹅也能保持较好的生产性能。

Study on application of rice bran in goose diet

In order to the determine the effect on nutrients utilization in diets and geese productivity by altering ratio of rice bran and regulating different contents of metabolic energy and protein in the diets.Feeding trial and metabolic trial were carried out with Hepu geese.Different ratio of rice bran in trial 1 and different contents of metabolic energy and protein in trial 2 in the diets were measured for utilization efficiency of nutrients of the diets and body weight gain of geese.The results showed that nutrients in the diets had high the utilization efficiency and geese could get good daily gain when diet contained 12.0 %-20.0 % of rice bran and contents of metabolic energy and protein were 10.0-11.0 MJ/ kg and 14.0 %-17.0 % in the diets,respectively.
