Effect of Poly-Herbal Mixture Supplementation during Post partum Period on Feed Intake and Reproductive Performance of Sahiwal Cows

To investigate effect of poly-herbal mixture supplementation on feed intake and reproductive parameters, 12 Sahiwal cows at peri-parturient period were selected and divided into two groups of 6 animals each on the basis of body weight, parity and expected producing ability. Control group was fed basal diet alone while in supplemented group alongwith basal diet, poly-herbal mixture was given @ 450 g/animal/d from day of calving up to 7 days continuously and then on alternate days up to day 21 and then at weekly interval up to day 60. Body weight, feed intake and milk production were better (P<0.05) in supplemented group. There were no cases of RFM and metritis in supplemented group and rapid rate of cervix and uterine involution was observed in supplemented group compared to control. There was significant (P<0.05) reduction in interval from calving to 1^st observed estrus, number of services per conception and service period while increase (P<0.05) in first service conception rate in cows of poly-herbal mixture supplemented group. Hence, poly-herbal mixture supplementation in diet of Sahiwal cows @ 450 g/animal/d improved post partum reproductive performance.
