Three varieties of Panicum maximum Jacq. were evaluated by measuring the botanical and chemical composition of the diet, and the dry matter intake and weight gain of the animal under rotational grazing, before and after a period of grazing. The treatments were: 1) v. Tanzânia + 50 kg N/ha, 2) v. Tanzânia + 100 kg N/ha, 3) v. Mombaça + 50 kg N/ha, and 4) v. Massai + 50 kg N/ha. Of the diets selected by the animals, v. Massai […]

This work was carried out from December/95 to February/96 to evaluate the effect of two herbage allowances, 4 and 8 kg green herbage dry matter/100 kg live weight, on milk yield of crossbred cows grazing Signalgrass (Brachiaria decumbens). A completely randomized design was used, and milk yield corrected to 4% fat was analyzed by covariance. During the first and second grazing cycles, herbage availabilities were 4392±974 and 2598±591 kg/ha green herbage dry matter in the paddocks, respectively. Herbage allowances had […]
