How long after detection of estrous should sows be inseminated?

The recommended timing for insemination after the detection of estrous in sows is 24 hours. This is because ovulation typically occurs about 36 to 42 hours after the onset of estrus. Inseminating at the 24-hour mark allows the sperm to be present in the reproductive tract as the egg is released, maximizing the chances of successful fertilization. Timing is crucial in breeding management, as it enhances the likelihood of conception when the optimal conditions coincide with ovulation.

Other timeframes, such as 12, 48 hours, or 6 hours, may either miss the fertilization window or lead to infertility, making the 24-hour timing the standard practice for effective breeding in swine management.
