摘　　要：利用Wood模型拟合荷斯坦牛的泌乳曲线 ,其拟合精度为R2 =0 .2 0 1 7～ 0 .490 3,不够理想 ;若剔除第 1个泌乳月 ,对 2～ 1 0个泌乳月的泌乳资料再次拟合 ,则拟合精度明显提高到 0 .Fitting analysis of Holstein lactation curve based on Wood model, it showed that fitting accuracy (R 2) of Wood model ranged from 0.2017 to 0.4903; when all data of milk yield except the first month were applied to fitting analysis, fitting accuracy was improved obviously, to 0.9 or so.

关 键 词：荷斯坦牛 泌乳曲线 WOOD模型 拟合精度 生产性能
