摘要: 本研究对新疆昌吉地区荷斯坦牛2011~2014年185 340条日单产记录进行统计分析,分别采用5种模型(Wood、IQP、Wilmink、ML、AS模型)对第1、2、3、4胎及所有胎次泌乳曲线进行拟合。结果表明,Wood、IQP、Wilmink、ML、AS模型拟合精度范围分别在0.9562~0.9828、0.9467~0.9809、0.8671~0.9752、0.8752~0.9175、 0.8775~0.9127范围内;Milmink模型为第1胎次泌乳曲线最佳拟合模型,Wood模型为第2、3、4胎次泌乳曲线的最佳模型。

Abstract: In this study,the statistical analysis data of 185 340 Holstein dairy cows daily yield records were collected from 2011 to 2014 years in Changji area of Xinjiang,five kinds of models (Wood,IQP,Wilmink,ML,AS models) were used for the first,second,third,fourth and all parities fitting lactation curve.The results showed that the Wood,IQP,Wilmink,ML,AS models fitting precision were within the range from 0.9562 to 0.9828,0.9467 to 0.9809,0.8671 to 0.9752,0.8752 to 0.9175,0.8775 to 0.9127;Milmink model was the best fitting model for the first parity lactation curve,Wood model was the best fitting model for the second,third,and fourth parities lactation curve.

Key words: Holstein dairy cows; lactation curve; goodness of fit
