摘要
为了探讨仙湖鸭产蛋率的特点、规律,并在实际生产中进一步挖掘仙湖鸭产蛋性能,本试验采用Wood模型、Yang模型和McMillan模型等3种数学模型对仙湖鸭产蛋曲线进行拟合分析,结果表明:Yang模型和McMillan模型能很好地拟合仙湖鸭的产蛋曲线,拟合度R2值分别达0.9790和0.9784,优于Wood模型。
The aim of this paper was to probe characteristic and the regularity of egg performance rate in Xianhu ducks, and improve egg performance in practical production. The egg performance curves of Xianhu ducks was calculated by three mathematical models, including Wood model, Yang model and McMillan model. The results showed that the R2 value of Yang model and McMillan model was 0.9790 and 0.9784, respectively. So Yang model and McMillan model was better than wood model of the egg performance cures for Xianhu ducks.
