The aim of the study was to evaluate the relations between some morphometric traits of the reproductive system of primiparous sows determined after slaughter and their fertility. At the age of 140 days the animals were fed with the insulingenic diet (21 days). They were divided into two groups and mated at first (A) or second estrus (B). The number of born piglets was significantly lower in A than in B sows (8.70 vs. 10.05). There were positive and significant correlations between the fertility of A sows and left ovarian weight (r=0.49;), and between the number of piglets and uterus-cervix length in B sows (r=0.40). Moreover, there were significant interrelations between the different elements of the reproductive system (uterus with ligament weight, uterus capacity, ovaries weight, cervix-uterus and horns length).
