Insemination and maternity

Sows should be inseminated 12 to 24 hours after standing in estrus and again every 12 to 24 hours after the first insemination for as long as they stand in estrus.
Gilts are commonly inseminated as soon as standing estrus is detected and every 12 hours afterwards as long as they are still standing in estrus.

To achieve optimum results, semen should be in the female reproductive tract 6 to 8 hours prior to ovulation. Since sperm cells can live for up to 24 hours in the female’s reproductive tract, it is better to inseminate early in estrus rather than late.
