Abstract: The objective of this study was to analyse the effect of body condition on female’s receptivity and fertility. A total of 119 primiparous rabbit does were weighed 10 days after delivery, i.e. mating of their third gestation, and fat deposits were measured through the perirenal fat thickness using ultrasound images. Weight and perirenal fat thickness were similar between receptive and not receptive primiparous females to the first mating after postpartum. Rabbit does pregnant showed a greater weight (+0.18 kg) and a greater perirenal fat thickness at mating (+0.36 mm) than those non-pregnant. The logistic regression analysis showed that weight and perirenal fat thickness were not related to the probability of female accepts mating (P > 0.10). Receptivity is only affected by season, e.g. the probability of acceptation the mating is less in winter than in both spring and summer. Weight and perirenal fat thickness showed a positive relationship with the probability female’s being pregnant (b = 1.27 and b = 0.62 respectively, P <0.10). In conclusion, body condition does not affect female’s receptivity, but it affects its fertility.
