EFFECT OF MINERAL SUPPLEMENTATION ON INVOLUTION, POST-PARTUM OVARIAN ACTIVITY AND CONCEPTION RATE IN MARATHWADI BUFFALOES

The present investigation was planned to study effect of mineral supplementation on involution, post-partum ovarian activity, post-partum oestrus and conception rate in 14 Marathwadi advance pregnant (after 10 month) buffaloes, maintained by farmers in the rural area adjacent to Parbhani town. Group-I were taken as (treatment group) those animals shown Ca and P level below normal range and Group-II were (control group) include those animals shown serum Ca and P level within normal range. Seven buffaloes were kept under each treatment. The buffaloes in group-I were provided with mineral supplement 50 gms before and after 7 day of parturition. The average duration required for complete uterine involution was observed as (38.14 +/- 0.88, 41.71 +/- 1.78 days) while the post-partum estrus was (63.57 +/- 2.22, 69.86 +/- 2.52 days) from Group 1 and Group 2, respectively. In the present investigation the resumption of ovarian activities in the buffaloes were 4th week (25-34 days) and 5th week (31-43 days) in Group 1 and Group 2, respectively. The conception rate in the present study was 85.71 percent and 71.42 percent from Group 1 and Group 2, respectively. It can be concluded from the present findings that the irrespective of statistical numerical significance there was decline average days required for uterine involution and postpartum oestrus in treatment group as compare to control group. The early resumption of ovarian activities and conception rate was also higher in treatment group. Due to pre-partum dietary mineral supplementation, which resulted in prevention of post-partum disorders in treatment group of buffaloes.
