Study with 40 gilts from two different origins - LW x L and LWxL xD was carried out. The age of I, II and III estrus and interval between I: II and II: III estrus was following out. The weight and linear development of reproductive system after III estrus was estimated. The results show average age for maturity 178.6 days in LW x L and 182.5 days in LWxL xD. The 3.9 days difference between two origins is not significant, which means that in this farm the gilts origin is not determinative factor for functional development of reproductive system. Period between I: II and II: III estrus 20.8 - 21.2 days is practically equal in two studied origins. The same tendency is establish about the weight and linear development of reproductive system. Differences between total weight - 520 g v.s. 507 g and uterus horns are due to individual peculiarity of animals and the breeding and feeding conditions in the farm.
