Abstract: Post-partum affections are major causes of infertility in dairy cattle. The main objective of study was to evaluate the reproductive and productive parameters of Holstein cows suffering from retained fetal membranes (RFM) subjected to different therapeutic protocols. The cows were 4-8 years old at their 2nd to 6th calving season. Methods: Forty cows diagnosed with RFM were divided equally into 4 groups according to the assigned treatment protocol, group 1: manual removal of the RFM + 2gm intrauterine Oxytetracycline, group 2: injected 50 I.U/i.m Oxytocin, group 3: injected 500μg/i.m cloprostenol (PGF2α, analogue), group 4: injected of 2.5mg/i.m Carazolol (Beta-Blocker). A group of 10 cows was designed as control (fetal membranes were shed within the first 12 hours after parturition). Results showed that the least time needed to expel fetal membranes achieved by PGF2α treatment (18.20±1.22 hours). Cows treated with PGF2α showed significantly shorter days open (100 days) and calving interval (380 days) compared to other groups.
