Comparative Effect on Clinical use of PGF2α and REPROCINE in the Treatment of Retained Placenta in Dairy Cows at TIARET Region (Algeria)

The aim of this study was to determine which protocol allows cows, subject to a retained placenta, to recover their reproductive performances as soon as possible, using an injecting of REPROCIN (Carbetocin) a delayed oxytocin, intramuscularly at a dose of 10 mg, 24 h after parturition and that of CLOPROSTENOL (a synthetic analogue of Prostaglandin F2a), also used intramuscularly at a dose of 50 mu g, 24 h after parturition, compared to a control group. The results show that injection of a standard dose of PGF2a in case of retained placenta, has a significant effect on uterine involution, 60% of animals which had a normal involution against 40%, as well as a significant impact on reduction of postpartum metritis in dairy cows, especially during the first month after calving, 10% of animals affected against 30%. The same positive effect was observed with the interval calving-fertilization, the study shows 70 days against 112, 4 days.
