Description
Young bulls of different breeds ( Zebu, Holstein and F-1 strain Holstein Zebu) were grazing together on a meadow composed of Guinea grass (Panicum maximum), Brachiaria (Brachiaria decumbens) and a mixture of natural pastures, all in association with Leucaena (Leucaena leucocephala) sown at a density of 555 plants per ha in order to evaluate the potential of that system for beef production. A completely randomized design was used. The meadow was rotationally grazed at stocking rate of 3.6 animal per ha. During the 18 months of fattening the best results were obtained with the Zebu type. The final weight of those bulls occurred to be significantly (P< 0.05) superior (413.7 vs 357.4 and 376.3 kg) when compared with Holstein or F-1 cross. The gains obtained by the Holstein and F-1 bulls could be considered satisfactory.
