Sound pasture management must consider the requirements of both plants and animals and their interrelationships. One of the most important factors that can be controlled in a system of grazing management is the length of the regrowth interval of the forage between grazings. Tests recently conducted at Davis, during two pasture seasons, studied the effect of forage recovery intervals of 24, 30 and 36 days. The stocking rate was held approximately equal to obtain the same degree of grazing intensity.
