Abstract
The purpose of our research was to define changes in sows culled due to reproductive disturbances of genital organs, to evaluate functional condition of the ovaries and the stage of reproductive cycle. In order to study these parameters, 60 sows with disturbed reproductive cycles, Lithuanian White × Danish Landrace (LWxDL) and purebred Danish Landrace (DLxDL) were slaughtered. After slaughtering, the reproductive organs of all the sows were evaluated and it was concluded that 80% of the culled sows’ ovaries continued to be active and an anoestrus stage was defined in 20% of the sows. Multiple follicular cysts were found in 3.33% of all culled sows. It was defined that the total count of follicles in both ovaries had no statistically reliable effect on the weight of genital organs, while the CL count greatly affected not only the weight of the genital organs but the stage of the sexual cycle (P≤0.001), the consistency of the cervix (P≤0.01) and vice versa. The average weight of the genital organs varied, depending on the sexual stage (P≤0.05) Our experiments proved that post-mortem examination of genital organs in sows and palpation of the uterus cervix are effective methods of defining the stage of sexual cycle and important diagnostic tools in the evaluation of reproductive disturbances.
