POSTPARTUM UTERINE INVOLUTION IN PRIMIPAROUS AND PLURIPAROUS POLISH LONGWOOL SHEEP MONITORED BY ULTRASONOGRAPHY

Abstract

The study was carried out on 29 primiparous and 22 pluriparous winter–lambing, suckling Polish Longwool sheep variety Kamieniecka. The completion of uterine involution was determined by means of transrectal ultrasonography. Parameters for the evaluation of uterine involution were the transversal diameter and the presence of uterine lumen. The results show that uterine involution was completed in the majority of ewes till day 35 postpartum. Furthermore, the results indicate that parity affected uterine involution. It was completed earlier in primiparous than in pluriparous ewes.
