Abstract
The economic return that is realized by a commercial swine operation is largely determined by the efficiency of the sow herd. Increasing litter size and shortening the interval between litters results in greater yearly production per sow unit. Weaning at 2 weeks and allowing 10 days for rebreeding, theoretically, allows the production of 2.65 litters per sow per year~ compared to the national average of 1.7 litters. This study was conducted to determine the effect of weaning age on post weaning performance
