We used twenty-nine Anglonubianas goats, divided evenly into two groups: group PGF2a (0.133 mg cloprostenol) and control group (0.5 mL of saline (0.9%)), both received two doses on days 1 and 4 postpartum. By transrectal ultrasonography on days 1, 4, 10, 16, 22, 28, 34, 40 and 46 after birth, were evaluated uterus and ovaries. The uterine diameter behaved differently between the groups (P<0.05) in animals PGF2a there was a marked reduction in uterine diameter for 22 days postpartum (3.5 ± 0.6 cm), animals control, occurred until 28 days postpartum (3.6 ± 0.8 cm). The expulsion of uterine contents was earlier in animals PGF2a (D40), while in control animals was completed in 46 days postpartum (P<0.05), as occurred with the presence of cervical mucus (absent in animals PGF2a - D34 and control - D40). There was follicular growth in all animals (P> 0.05), however there were no ovulations. The cloprostenol during the study period acted beneficially in the process of uterine involution and the expulsion of uterine contents in dairy goats.
