With the aim to clarify the effect of seasonal variation on reproductive performance of hybrid rabbits, a six-years investigation was carried out. Traits analysed were pregnancy rate of does and numerical productivity at weaning. The data set included: 33588 matings and subsequent pregnancy diagnosis; 245743 young rabbits at weaning. From the statistical analysis, pregnancy rate and numerical productivity at weaning appeared to be significantly (P<0.001) affected by seasonal variation. Furthermore a statistically significant (P<0.001) month influence was also found. Nevertheless a correlation between the two parameters needs to be performed to supplement our analysis.
