Effect of prepartum supplementation of Rovimix- Hy-D^® on occurrence of periparturient disorders in crossbred cows

A study was conducted to determine the effect of prepartum supplementation of anionic salts and cholecalciferol (Rovimix Hy-D®) on incidence of periparturient disorders and serum calciumphosphorus levels at calving in crossbred cows. Total forty advanced pregnant cows of six farms in three villages of Anand district were selected and divided equally on each farm into treatment and control group. The animals in control group were fed with concentrate mixture, green and dry roughage as per availability; whereas animals of treatment group received Rovimix Hy-D® @100 g/animal/day in addition to regular green, dry and concentrate feed for a fortnight prepartum. The incidence of peripartum disorders noted (mainly retention of placenta, uterine prolapse, endometritis and milk fever) was much less in animals of treatment group as compared to control group (15 vs 45%). Serum concentrations of both calcium and phosphorus were higher in treated group than the control group (10.73±0.21 vs 10.26±0.26 and 5.55±0.12 vs 4.89±0.14 mg/dl), but the difference was significant only for phosphorous levels.
