【摘要】 在对45头配种后的三江白猪的外周血小板数值进行统计分析的基础上，应用聚类分析和非线性回归方法建立了三江白猪相关性血小板早孕预测模型．根据这些模型所确立的方法对112头具有正常繁殖机能的配种后的三江白猪进行超早期妊娠诊断的试验，其结果与实际分娩产仔的符合率分别为：模型1：79．38％；模型2：84.53％；模型3：89．53％。因此，这些模型所确立的方法，能够准确地预测三江白猪的超早期妊娠情况。更多还原

【Abstract】 The early pregnancy calculation model related to platelet with cluster analysis and nonlinear regreresion was set’based on statistic analysis on the semodels of periphersl brood platelet in Sanjiang White pigs(n=45) after service . The, diagnosis of ultra-early pregnancy in healthy Sanjiang white pigs (n=112) after. service was taken with these model.The result indicated the calculation accuracy of model was 79.38%(Mod.Ⅰ).84.53%(Mod.Ⅱ).and 89.53%(mod.Ⅲ).So these model could be calculated accurately ultre-early pregnancy in Sanjiang white pigs.更多还原
