A hormone injection to induce super ovulation is generally done after which day following calving?

The correct answer is based on the typical reproductive cycle of cattle and the timing for hormonal intervention to maximize ovulation. After calving, it is essential to allow the cow’s reproductive system sufficient time to recover and to resume normal hormonal cycles.

Administering a hormone injection for super ovulation is generally done around 60 days postpartum. This timing aligns with the natural return to estrus and allows for the reestablishment of ovarian function following calving. By this point, the cow has likely begun her reproductive cycle again, and inducing super ovulation can effectively enhance the number of viable eggs produced, which is particularly useful in breeding programs for improving genetics and productivity.

Timing this intervention too early, such as around 30 days postpartum, may not provide the reproductive system adequate recovery time, possibly leading to poor outcomes in terms of ovulation and conception. Similarly, waiting until 90 days or beyond may miss optimal breeding windows or extend the interval between calving and conception longer than desirable. Thus, 60 days is widely regarded as the optimal time frame to balance recovery and breeding efficiency.
