Medium White turkeys in Generation 10 of divergent selection for semen ejaculate volume (SEV) were classified into lines that produce either low or high volumes of semen using a multivariate statistical technique, discriminant analysis. The discriminant function was based on records of hen fertility, embryonic mortality in the early and late incubation periods, and the incidence of pipped eggs. A hit ratio, the proportion of birds correctly categorized as low or high, of .60 was obtained. The discriminant function was subsequently used to classify birds in Generation 12. A misclassification rate of .28 and .48 was obtained for birds in the low and high lines, respectively. It was concluded that the relatively low rates of misclassification indicate a potential method for identifying male and female turkeys as belonging to low or high SEV lines, based on fertility and incubation records.
在对精液射精量（SEV）进行差异选择的第10代中型白羽火鸡中，使用多变量统计技术判别分析，将其分为精液产量低或高的品系。判别函数基于母鸡受精率、孵化前期和后期的胚胎死亡率以及啄壳蛋的发生率记录。得到的命中率，即正确分类为低或高的鸟类比例为0.60。随后，该判别函数用于对第12代的鸟类进行分类。低产和高产品系的鸟类错误分类率分别为0.28和0.48。得出的结论是，相对较低的错误分类率表明，基于受精率和孵化记录，有一种潜在方法可用于识别属于低或高SEV品系的雄性和雌性火鸡。
