Description
Herbage intake, digestibility and leafiness or bulk density are well known as the main factors affecting the performance of grazing animals. But even in case where these factors are not so different, daily gain still varies among seasons or individuals (Blaser et al., 1981). In order to solve these problems by modeling approach (Okubo & Jacquard, 1985), seasonal changes in plant production, daily gain of cattle live-weight and seasonal variations in solar energy conversion into cattle gain were measured, and the importance (Okubo et al., 1985) of gross efficiency of digestible energy to net energy was discussed.
