A two-litter pasture farrowing herd of 100 sows was budgeted. Based on current market prices (1996) and marketing 7.5 feeder pigs per litter, the cost of production was $37 per 50 lb pig for all costs or $31 per 50 lb pig excluding labor. Sensitivity analysis clearly showed that pasture farrowing is competitive as a land use with corn and soybean production.
