The following results were obtained from experimental studies into selection of laboratory rats for fertility and random mating with oestrus being synchronised by means of Suisynchron-Prämix, through eight generations: --Success of selection without synchronised oestrus was higher than that with synchronised oestrus by selection according to the basic index and with one and the same selection intensity. --Litter size and weight were higher in the selected variants, as a result of increased potential fertility (rate of ovulation). --In the population with selection and synchronised oestrus a negative relationship was found to exist between the directly correlated selection results regarding fertility parameters, on the one hand, and the effect of synchronisation, on the other. --Both the rates of ovulation and litter parameters were lower in the population with selection and synchronised oestrus, as a result of synchronisation. --The effect of synchronised oestrus on the population with selection and synchronised oestrus was partially eliminated owing to selection for fertility.
通过八代实验研究，利用苏西同步 - 普瑞米克斯（Suisynchron-Prämix）使发情同步化，对实验大鼠进行生育力选择和随机交配，得出以下结果：
根据基本指标并在相同选择强度下，未进行发情同步化的选择成功率高于进行发情同步化的选择成功率。
由于潜在生育力（排卵率）增加，所选品系的窝仔数和体重更高。
在进行选择且发情同步化的群体中，一方面关于生育力参数的直接相关选择结果与另一方面同步化效果之间存在负相关关系。
由于同步化，在进行选择且发情同步化的群体中，排卵率和窝仔参数均较低。
通过对生育力进行选择，发情同步化对进行选择且发情同步化的群体的影响部分得以消除。
