The concept of significantly increasing the lean meat output per AI boar via assisted reproductive technology is important. Early programs have given producers better estrus detection, better estrus behaviour, and better AI practice to enhance production. Good estrus detection is essential for detecting when the time is right for AI. Good estrus detection can minimize the wean-to-estrus interval and help developing gilts via visual, audio, smell, and tactile stimulation. The sequence of events that are followed for heat detection should be monitored in order to attain a good standing heat in the sow. Proper stimulation should be administered before the question of “is she in heat or not?” arises. Boar-sow interactions should be limited to the critical breeding period so that muscular contractions during heat are maximized. This will result in a higher conception rate and litter size. AI techniques are being developed so that intra-uterine insemination can be done (rather than cervical insemination). This will reduce the number of sperm per dose by a large amount without the loss in productivity. 3 billion sperm per dose is the average used today, and the use of intra-uterine insemination can lower that number to 1 billion per dose.
