| 摘 要： | 试验研究结合生产实践,采用大群生产试验方法,对标准化饲养的2 847个批次、3 094.4万只樱桃谷肉鸭,按统一的饲养方式和管理程序进行生产试验,研究了不同季节对肉鸭生产性能和蛋白质需要量的影响,并进行了肉鸭不同季节蛋白质需要量析因模型研究,结果表明:樱桃谷肉鸭达到基本一致的出栏体重的目标条件下,春、夏、秋、冬四个季节的饲养天数均差异显著(P<0.05),且夏、春、秋、冬四个季节依次减少;秋季的饲料消耗量显著高于春季和夏季(P<0.05);冬季的料重比显著高于春季(P<0.05)。樱桃谷肉鸭地面饲养模式下,维持需要的粗蛋白质:夏季<春季<秋季<冬季;增重需要的粗蛋白质:夏季>春季>秋季>冬季。不同季节蛋白质需要量可用以下析因模型进行预测:春季:CPR=211.0BGW+6.315W0.75;夏季:CPR=220.9BGW+6.013W0.75;秋季:CPR=202.5BGW+7.591W0.75;冬季:CPR=185.5BGW+8.138W0.75。式中:CPR——肉鸭粗蛋白质需要量g(/d.只)];BGW——活体增重kg(/d.只)];W0.75——代谢体重(kg)

| Abstract: | In this paper,in order to study protein requirements and factorial model of cherry valley ducks in different seasons,connecting with the produce practice,we utilized productive testing methods for large group of 3 094.4 cherry valley ducks,which were bred and managed in the same way in 2 847 standardized duck sheds.The results indicated that the raising days of cherry valley ducks showed significant differences(P<0.05) in different seasons and were progressively less from summer and spring to autumn and win... |
