摘要
根据AA父母代肉鸡第25～65周龄的群体产蛋记录,用伍德模型、杨宁模型和分室模型拟合了入舍母鸡的单周、双周产蛋曲线.三种模型拟合的R2值分别为:伍德模型0.807 14(单周),0.862 31(双周);杨宁模型0.995 33(单周),0.979 41(双周);分室模型0.995 53(单周),0.99205(双周).分室模型最适于肉种鸡群产蛋曲线的拟合.
The 25~26 week AA broiler was fitted by Wood model,Yangning model and McMillan model according to single week or double weeks laying rate.The R2 values of these fitting were 0.8074 (single week) ,0.86231 (double weeks),0.99533 (single week) ,0.97941 (double weeks) ,0.99553 (single week) ,0.99205 (double weeks). McMillan model was optimum model of egg production for broiler.
