Study on the Pattern of Postpartum Uterine Involution in Dairy Cows.

ABSTRACT: Postpartum uterine involution is necessary for the normal reproduction of dairy cows. The study aimed to investigate the pattern of postpartum uterine involution and the impact of parity on uterine involution in Chinese Holstein dairy cows. The diameter of the uterine cervix, pregnant uterine horn, and non-pregnant uterine horn were monitored using a B-mode veterinary ultrasound scanner at 5, 10, 15, 20, 25, 30, 35, and 40 days, respectively, after parturition in both multiparous and primiparous dairy cows. Meanwhile, the concentrations of hydroxyproline, E2, and IGF-1 were detected using ELISA at 5, 10, 15, 20, 30, and 40 d after parturition in both multiparous and primiparous dairy cows. Furthermore, the duration of uterine involution was compared in the multiparous and primiparous dairy
