| 摘 要： | 本试验对2424羽(公404羽,母2020羽)5月龄樱桃谷SM3父母代种鸭产蛋量进行15个月的跟踪观测,并对产蛋率(Y)与饲养月龄(x)之间的回归关系进行分析。其回归方程:y=-361.983 117.989x-9.722x2 0.247x3。根据此回归方程可推算出樱桃谷SM3父母代种鸭各阶段的产蛋率,拟制定科学管理和饲养配套新技术,可望大幅度提高饲养效益。

| Abstract: | 2424 breeding ducks(404 drakes and 2020 ducks)in cherry valley duck breeds SuperM3 were experimented for 15 months.Egg production and laying rate counted monthly,and analyzed the regression between laying rate(y)and age(x).The regression equation is obtained as follows:y=-361.983 117.989x-9.722x2 0.247x3 in duck production.We can use the equation to calculate laying rate in any time so as to plan duck production rationally.Base on this regression equation,we can make scientific management technology and new feed technique,and improve economic benefits of breeding ducks. |
