The permanent paddocks will only get in the way while you're trying to learn how to best graze your ground.
The majority of our cattle don't back graze, simply because they have a fresh paddock to graze from every day.
One way to use summer grass is to buy small yearlings in spring when grass begins to flourish, graze them until fall, and sell them when pasture quality and quantity begins to decline.
If you have good quality tame pastures (with adequate rainfall or irrigation) you can get maximum beef production per acre by using rotational grazing, timing the grazing of each small pasture segment when the plants are most ready, then letting them regrow while you graze another part.
When several observers spaced across the narrow graze
zone time all events, a detailed profile of the lunar mountains can be constructed.
This is done by allowing the cattle to have access only to a very small acreage during each graze
to prevent them from wandering aimlessly about and ruining forage.
