Abstract
Retained fetal membrane (RFM) is a crucial calving related disorder that affects economic for the farmer and herd health. Retention of Placenta (ROP) is the condition in which the fetal membranes are not expelled within a period of 12 hours after parturition. Buffalo cows (n=34) aged 4-9 years old with 2-6 lactation season were used in the present study. The Experimental buffaloes were divided into either with (n=25) or without (n=9) fetal membrane retention. The objective of this study was to evaluate the effect of oxytetracycline treatment on reproductive performance of buffalo-cows with retained fetal membranes. All buffaloes in treated group received systemic infusion of oxytetracyclin Hcl injection 5% and 10 mg/kg oxytetracycline for 3 days intrauterine. Reproductive performance parameters for all experimental buffaloes were days to first estrous, number of service per conception, days open and pregnancy diagnosis. All reproductive parameters demonstrated significant changes between treated and non-treated animals (P < 0.05). Altogether, the obtained results indicated that retained placenta in buffaloes could be treated successfully by intrauterine infusion of oxytetracycline
Highlights
The incidence of retention of placenta in buffaloes ranged from 10-15%
Reproductive performance is economically important in dairy buffaloes because it affects milk yield and culling rate
Poor reproductive performance due to post-partum reproductive disorders can reduce the number of born calves and milk production and increase the cost of nutrition, therapy and artificial insemination
Summary
Following RFM, the uterus becomes contaminated with bacteria which have a negative impact on reproductive performance in cattle including delayed uterine involution, a prolonged interval to first service, an increased number of services per conception,, a decreased conception rate and a prolonged interval of days open [3,4,5]. RFM have been associated with increased risk for endometritis, metritis, ketosis [6] and mastitis. These diseases can in turn lead to decreased fertility and potential losses in milk production [7]. Postpartum metritis is common sequelae of RFM, and the rationale behind antibiotics application for RFM to prevent or treat metritis and its negative effects on fertility [7]
