Description
In the central part of Honshu island in Japan, seasonal variation of herbage mass is also large (Okajima et al., 1985). So, when the grazing managements, i.e. stocking rate, grazing intensity etc., were not appropriate, part of herbage produced was lost through standing dead and litter, or grazing cattle lose their body weight. Sward characteristics affect the grazing behaviour of cattle (Jamieson and Hodgson, 1979), and then affect the herbage production and utilization. Relative herbage intake of cows was related to sward height (Baker et al., 1981). So, sward height was used as the indicator of the grazing management in experiments of this paper, and the objectives are (1) to compare the seasonal change of herbage mass and (2) to compare the animal production between two different grazing managements on sward height.

The Relationship of Herbage Intake of Cattle to Herbage Mass, and its Utilization on Rotationally Grazed Pasture
