Conteúdo: 	Grazing and greenchop experiments were conducted simultaneously every 28 days during a six-month period (1) to estimate the seasonal variation in nutritive value of a Pensacola bahiagrass pasture, (2) to evaluate the performance of grazing steers on this pasture, (3) to compare estimates of intake by grazing animals with animal performance and (4) to compare sampling methods for estimating quality and quantity of pasture throughout the season. Measurements of live weight changes by grazing yearling steers and estimations of pasture organic matter (OM) intake by different techniques were made for each period. Calculated OM and total digestible nutrients (TDN) yield of the pasture and chemical composition of forage samples were also obtained. Results of an intake and digestion trial with greenchop were compared to the results obtained in the pasture trial. Average daily gain (ADG) by grazing steers declined from May to September, then slightly increased in October. It followed a trend similar to the general live weight pattern onserved in the flatwood areas, i.e., high ADG at the beginning of the grazing season, rapid decline as the summer progresses throuth September, and small increase in early fall. The low ADG by the steers during August and September was apparently independent of differences in the quantity of available forage and, thus, may have been caused by low OM intake. High rainfall, low forage palatability or low forage quality during late summer may have been the cause of the low OM intake. Estimates...
