Secretion of prostaglandin F2α at the time of maternal recognition of pregnancy leads to embryonic loss. Early embryonic losses are one of the important causes of repeat breeding which increases the calving interval and leads to economic losses to farmers. Non-steroidal anti-inflammatory drugs inhibit the synthesis of PGF2α. The present study was designed to study the effect of treatment by GnRH analogue - Buserelin acetate, Progesterone (P4) and Tolfenamic acid on 32 repeat-breeding crossbred cattle aged 3-8 years. | Evaluation of the effect of GnRH analogue progesterone and tolfenamic acid on serum progesterone profile and conception rate in repeat breeding crossbred cattle
