Abstract

The grazing trial was conducted from December, 1980 to October, 1985, in the Southeast of the State of So Paulo, Brazil, comparing the behaviour of four tropical mixed pastures under three grazing preassures (low, medium and high). The management system used was the continuous grazing one with variable stocking rates during different times of the year. Each kind of mixed pasture was composed by three paddocks of different sizes (0.63, 0.83 and 1.25ha) which were maintained with the same number of animals during certain time. The data were analyzed by co-variance comparing regression limes, utilizing only one replication. It was studied the seasonal variations of the botanical composition as well as the crude protein contents of each species in the mixtures. The standard mixture was green panic plus calopo which showed a mean of 10.55% CP; 39.81% CF, and 42.26% IVDMD. In the comparison between the standard mixture with the others studied, the mixtures kazungula setaria + galactia, and makueni + stylo capitata, had less protein content (P < 0.05), although they did not differ statistically from the standard mixture. So, green panic + calopo showed a reasonable balance grass/legume and are suited to be used in the Southeast part of the State of São Paulo.
