Don't miss the first insemination

摘要

To have maximum success in terms of fertilisation, an insemination should take place within 24 hours preceding the time of ovulation, at least when using semen of good quality and not older than two days (Table 1; also see PigLink seminar by Roy Kirkwood). When the first insemination is performed too early (more than 24 hours before ovulation), a second or even third insemination will ensure a good fertilisation, as long as the .repeated insemination does not take place more than 24 hours after the previous one.
