Abstract
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-immunoassay (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.
Highlights
The goat population in Sudan is composed of four major local breeds, i.e. Nubian, Desert, Nilotic, and Dwarf goats (Wilson, 1991; MARF, 2009)

Summary
The goat population (about 43.3 million) in Sudan is composed of four major local breeds, i.e. Nubian, Desert, Nilotic, and Dwarf goats (Wilson, 1991; MARF, 2009). Nubian goats are among the best known dairy breeds in Africa especially in Sudan where they comprise 47% of the total goat population (AOAD, 1990). Nubian goats in Sudan are prolific and nonseasonal having 147 days lactation length with a milk yield of 1.5-2.0 kg per day and 150-200 kg per lactation. The body weight of Nubian goats is 50-70 kg in males and 40-60 kg in females (Ahmed et al, 2000). There is rapid shrinkage and contraction of the uterus, during the day 3 to day 10 pp, as determined by measurements of uterine weight and length, diameter of uterine body and previously gravid horn.
