Selection For Birth And Weaning Weight

Our research team weigh all purebred litters at weaning each week and now have over 4,000 litters weighed in the past 3 years. Our record weight at weaning is 138kg per 14 piglets (9.7kg) at 28 days – which demonstrates the potential of milking ability. Damline AI boars are selected from high milking sows weaning litters of over 120kg at 28 days as well as high MLI for Born Alive. After 20 years of teat selection Hermitage damline boar lines now average over 16 teats.
