The study was conducted to investigate and characteriz the time of uterine involution in local goats in Iraq by measuring the uterine diameter, uterine lumen (mm) and monitoring early post-partum ovarian activity as proved by Ultrasonography and progesterone assessment in local goats. 15 goats were submitted to examine from day 3 to 40 after kidding by Ultrasonography. Trans abdominal ultrasound approach was performed from day 3 to 5 after kidding and continued by trans rectal approach to follow up the uterine involution until day 40. Progesterone levels were measured starting from day of parturition, then a weekly measure until day 34 of post-partum period. Progesterone was assayed by Radio immune assay. The obtained results showed that complete of uterine involution started at day 26 (6.67) % and completed at day 34 post-partum in all does (100%). on the other hand involution of the uterus was completed at day 26, 27, 28, 29, 31, 33 after parturition  with a percentage of 6.67%, 13.34%, 33.34%, 40%, 46.67%, 66.67%, 73.34% and 80% respectively. Average uterine lumen (mm) from days 3-7, 8- 14, 15- 21, 22- 28, 29 -35 and 36-40 were 9.02, 5.82, 5.14, 3.51, 2.66, and 2.0 (mm) respectively. Average uterine diameter (mm) was 40.25, 33.9, 31.4, 25.57, 20 .15 and 16.35 at day 3-7, 8- 14, 15-28, 29-35 and 36-40 respectively. Regarding progesterone profile, results indicated that the mean value of the hormone was 0.267±0.005 ng /ml at parturition and the values were 0.320±0.007, 0.414±00.5, 0.536 ±0.013, and 1.945 ±0.129 ng/ ml at day 7, 14, 21 and day 30, respectively. It could be concluded that Ultrasonography image proved to be a valuable and safe tool in monitoring uterine involution and measuring of progesterone is a precise biological marker for the detection of resumption of ovarian cyclist during post-partum period.
