The net energy content for maintenance (NEm) and gain (NEg) of the napiergrass, under rotational grazing, as well as the changes on protein and fat concentrations in body and in weight gain of 36 ¾ Gyr-Holstein steers, grazing the forage, during the rainy season were determined. Half of steers had grazing time restricted to four hours daily, to limit energy intake to a level close to the maintenance level, and half had free access to the pasture. Six steers were […]
