If the plant does not have adequate leaf area to replenish root growth the plant will have a smaller root mass. This is why it is important to allow an adequate rest period during a drought. It is better to over graze just a small portion than to over graze the entire pasture. Managed grazing systems attempt to accomplish some of these things. The level of intensity depends upon the producer's goals.
Some producers are happy rotating on a daily basis.
They view it as doing their daily chores, although most that rotate daily do not call it a chore. Other producers wish to only rotate once every three to seven days, while others may rotate only once a month. Each system has its merits, and all can work as long as overgrazing does not occur.
