Strip Grazing Calculator

Strip Grazing is often used for short-term grazing across a large field or when stockpiled forage is grazed during winter. This calculator estimates the strip size of forage needed for a given size herd. It also estimates the number of grazing days from a pasture or paddock based on given forage availability. Field size, field width (feet), and forage height with forage density are needed.
