Conteúdo: | The effect of four fixed intensities of stocking and one variable stocking rate treatment upon pasture composition and animal production were investigated in a three-year study using small East African Zebu steers. Heavy stocking, with concurrent low availability of pasture and less opportunity for grazing, gave a significantly higher output of liveweight- gain per acre and lower individual animal production than the low stocking rates. Pastures stocked at one beast to 0.5 acre throughout the year produced a mean of 377 lb liweweight-gain per acre (423 kg/ha) per annum compared with a mean 147 lb liveweight-gain per acre (165 kg/ha) per annum from the leniently grazed pastures. Average daily gains were only reduced under conditions of severe grazing pressure. Animal production from the variable stocking rate treatment was low, particularly in the first two years, emphasizing a lack of objective criteria for obtaining optimal pasture utilization in the tropics. Continuous heavy grazing reducxed the proportion of Hyparrhenia rufa in the sward and caused considerable weed invasion. Stylosanthes gracils was better adapted to withstand heavy grazing. Lenient grazing in the dry season and heavy grazing during the rainy season produced good animal production without excessive sward deterioration. The practical application of these findings is discussed.
