Abstract
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.
Highlights
Progesterone was assayed by Radio immune assay
Uterine involution in goats and morphological changes and their delay in the sheep is characterized by rapid decrease of post-partum uterus and ovaries of farm uterine size and increase contraction rates, animals act as a limiting factor for the most commonly between the 3rd and the 10th reproductive performance following days postpartum, illustrated by measurements parturition [8]
The blood samples were collected during the time of parturition for determination of progesterone level, during post-partum period by weekly collection until the day 35 of post-partum, Progesterone hormone was measured by radioimmuno assay (RIA)

[14] Revealed complete macroscopic uterine involution at day 19 Post-partum, [15] reported that complete uterine involution occurred at day 28 Post-partum histochemical study of Caprine endometrium indicated complete regression of endometrial and re-epithelialization by day 16 Post-partum [16] With these discrepancies about the period necessary for complete uterine involution, decreasing logarithmic measurement, the greatest change occurring during the first few days after parturition and with rapid shrinkage and contraction of the uterus, during the day 3 to day 10 postpartum, as determined by measurements of uterine horn [2]
