| Abstract: | A dynamic, partially stochastic mathematical model describing the reproductive performance of a sow herd is presented. The model stimulates a herd that averages 17.27 sow days/pig produced, with a mean of 9.06 pigs weaned/litter and 2.327 litters produced/sow each year. Several alternative options are simulated. Of these, the ones that increase the litter size at weaning appear most beneficial in terms of both biological and economic efficiencies. |
