Master Pork Producer Keeping up with changes strengthens operation Hollis Janssen checks sow records in the gestation and breding facility he built severalyears ago when he moved his operation to total confinement. Janssen farrows weekly, weaning pigs at three weeks.
Pigs stay in the nursery nine weeks before they head to the grower.
They enter the finishing building at 21 weeks. In the past few years, the 1995 Iowa Master Pork Producer has gone to a total confinement operation. The independent man still has options available, and he can be a survivor of the changes we're seeing now. He markets most of his hogs between 250 and 260 pounds. Janssen has a feed mill on his farm, allowing him to program the ration on a computer.
