I often recommend people try a nine-square or Tic-Tac-Toe board setup where the field is divided into nine paddocks. The outer perimeter fencing is strong to keep out predators and in livestock. The center paddock is home and this can be made much smaller than the grazing paddocks. In the home square goes the housing, wallow, water, give any supplemental feed _in_the_evening_.
Then the livestock range out to the paddocks circling the home during the day. This gives a double fence for protection as well as making for very easy managed rotational grazing. To move the stock, simply close off the current grazing paddock in the evening and open the next one. The paddocks will improve over time. An additional trick that works very well with this is to mob seed in the last day or two that the animals are on a paddock. This allows one to adjust the mix of grasses, legumes and other forages. Fast growing foods like beets, turnips, kale, rape and such can be grown for the animals when they get around to that paddock again.
All the paddocks are well rested in the grazing cycle which helps with the parasite life cycle breaking. This does not rest the center paddock for that year so one might think that would be a parasite problem but I have not found that to be the case.
In the new year the home paddock will be richer and good for growing a longer season crop for the livestock. By using temporary fencing it is fairly easy to shift all the paddocks slightly in the spring so that a new home paddock is formed and the stock kept of the garden paddock which was the old home. If you wish to do it with permanent fencing in the interior paddocks then simply setup multiple home paddocks and those are gardens in the alternative years. This is a good, sustainable permaculture style arrangement.
