You set up paddocks with hot wire. Enough space that your animals can eat in 24 hours but no more then half to two thirds so the grass recovers faster. Your pasture will go farther this way. And move them every day. So they dont get back to the first paddock for about 30 days or more depending on how much land you have available.

This allows the grass to fully recover before they eat it again. It mimics how the wild herds eat. They also water fertilize and plant seed. Around august you set aside pasture for winter stockpile no grazing till winter, the grass lays over under snow and they will dig it up.

It is possible if the winter is to harsh they may not be able to get to it. So its,a good idea to have some emergency hay on hand.

Goats and sheep are better at finding winter stockpile then cows. But the cows will follow their lead. You use paddocks in winter also.
