Forage performance and cattle production as a function of the seasonality of a Brazilian tropical region

This study aimed to evaluate forage yield, tiller population density, canopy height, nutritional value as well cattle performance in alternate stocking from three tropical cultivars. The experiment followed a randomized block design, 3 x factorial scheme with replications. Three cultivars (Marandu, Massai and Xaraés) distributed nine hectares were evaluated dry season periods (transition wet/dry, dry, end of season), repeated measures over time. following variables evaluated: leaf: stem ratio, mass, leaf mass dead material mass. Total digestible nutrients, crude protein vitro digestibility regarding nutrition. Animal performance, using 36 eleven-month-old animals (half-blood Nelore), was by the daily average gain weight area. During pre-grazing, height presented interaction among periods. showed no period year similarity animal Marandu show that grass can be used an alternative for diversification under management system.
