Description
The objective was to determine weight changes of steers grazing African star grass (Cynodon plectostachyus) at four herbage allowances (2.0, 2.5, 3.0 and 3.5 kg of dry matter/100 kg of live weight day-1). A rotational grazing system with 10 grazing days and 30 days rest was followed. A Split Plot Design with four replications was used. Response variables were: daily gain per steer (DGS) and per hectare (DGH), dry matter forage yield (FY), % of utilization (% U) and in vitro dry matter digestibility (DMIVD). DGS and DGH were not different (P >0.05) among allowances and grazing periods. Percent of utilization had a similar trend during the year, but lower in the January-February period. The FY was not affected by allowances, but it was by periods. The DMIVD was different (P<0.05) among allowances and grazing periods.
