Paul Brown started pasture farrowing in (1991. Before that he had worked for his father-in-law who pasture farrowed 500 gilts, and Brown also had worked for a SOO-sow confinement operation. From these experiences, he decided what he wanted to do.

Gary Johnson focused on management of a pasture farrowing system. He follows a pasture farrowing calendar (he provided a printed copy). Nothing has changed except for some minor adjustments. However, if he doesn't follow it closely, he can have a disaster.

For Dave Odland, pasture farrowing is the conventional system. He farrows two sets of gilts each year. Although the number varies, typically he has 150 in first group and 100 to 150 in the second group that farrows in late July and August.
