A total number of 12 postpartum (pp) Nubian goats were included in the study to measure the uterine involution by ultrasonography from day 3 to 31 pp. Coinciding with ultrasonography, blood samples were collected at every 3 days to monitor the ovarian activity by measuring plasma progesterone (P4) concentration using progesterone radio-immuno-assay (RIA). Uterine diameter (UD) and uterine lumen (UL) were maximum on day 3, and minimum on day 31 pp. More than 50% of uterine involution occurred between day 3 and day 14 pp. The end of uterine involution was characterized by small UD and absence of lochia in the UL. The maximum (0.87±0.4 ng/mL) and minimum (0.54±0.2 ng/mL) plasma P4 levels were reported on day 27 and day 7 pp, respectively. Completion of uterine involution was recorded at 22±3.3 days pp. There was a negative correlation between P4 level and uterine parameters (UD and UL). It can be concluded that ultrasonography is a reliable tool to determine uterine involution in Nubian goats.
