The purpose of this lesson is to introduce students to the concept of grazing and its role in forage-livestock systems, the types of grazing, the advantages and disadvantages of each, the livestock considerations needed for better grazing, and a chart of grazing seasons. These topics will focus on specifics but the overall approach is to reinforce the concept that much of our land resources could be wonderfully productive if better managed. This section also contains several types of calculations needed to apply the principles presented.
