TREATMENT OF RETENTION OF PLACENTA IN RELATION TO SUBSEQUENT REPRODUCTIVE AND PRODUCTIVE PERFORMANCE IN FRIESWAL COWS

Abstract

All the cows expelled their placenta significantly earlier (p <0.05) in the Vitacept + Nutrimilk treated group (5.82 + 0.26 hours) as compared to untreated control (8.66 + 0.56 hours). Disappearance of lochia / conception rate were better in the treated group. Involution of uterus and occurrence of first postpartum estrus were significantly earlier in the treated group. In treated group the service period (72.60 + 3.13 days) was significantly less as compared to untreated control group (87.30 + 4.30 days). There was an improvement in 90 days milk production in treated (1344.4 + 68.17 litres) than the untreated control group (1012.4 + 85.17 litres). The mean serum calcium / inorganic phosphorus did not vary significantly during placental retention (9.92 + 0.1 mg % / 5.08 + 0.06 mg %) and normal calvings {10.46 + 0.29 mg % / 5.28 + 0.16 mg %). During retention of placenta the level of haemoglobin and differential leucocyte count did not show any significant difference compared to normal calvings. In retained cotyledons, the histomorphology revealed various stages of necrosis in trophoblastic cells. In some sections, an increased number of binucleate cells were also present.
