总产仔数、产活仔数与断奶个体重呈负相关。
The correlation are negative among total litter size, alive litter size, and body weight of piglets at weaning.
联合尺度检验法的结果表明：猪总产仔数和活产仔数的群体平均值分别为12 。
The results of joint scaling test showed that the population means for the total number born and the number born alive were 12.
母猪年龄是影响多产性的一个重要因素，初产的总产仔数和产活仔数均低于经产胎次。
Age is one important factor influencing of prolificacy, the TNB of first born is less than the TNB of the still-born, so does in the NBA.
方差分析结果显示，窝产仔数(总产仔数和活产仔数)具有极显著的群体间差异，表明不同群体的遗传结构不同。
The results of variance analysis indicated that litter size had extremely significant difference between populations, which showed that various populations had different genetic structure.
上位效应平方和占总产仔数和活产仔数总遗传变异平方和的比例分别为6 3%和6 5 % ，可见上位效应对窝产仔数群体间遗传差异作用不大。
Epistatic component accounted for 6 3% for the total number born, and 6 5% for the number born alive, which showed that epistatic effect was not important in the genetic variation between populations.
