Abstract

The objective of this paperwas to study the effect of  yield of Brachiaria humidicola cv Chetumal grass at  different frequencies and intensities of grazing. The cutoff  frequencies of 21 and 28 d and the intensities of 9-11 and  13-15 cm were evaluated, which were randomly distributed  in a random block design with 2*2 factorial arrangement  with three replicates. Management effects on dry matter  accumulation were observed, with accumulation at lower  frequency and light grazing intensity being greater. Forage  production had a seasonal distribution of 66, 26 and 7% in  the rainy season, north and dry seasons, respectively. The  leaf ratio in harvested forage was 20, 30 and 86% for north,  dry and rainy seasons, respectively. Reductions in dry matter  digestibility were observed in the north and rainy seasons  as the cut interval increased. The crude protein with severe  grazing was 11, 10 and 17% higher in the north, dry and rainy  times than with light. It is concluded that the highest forage  production was obtained when harvesting at a light intensity  of 13-15 cm, every 28 d and the highest protein content and  digestibility was obtained when the forage was harvested  at severe intensity every 21 d.
