The experiment was conducted to evaluate the feedlot performance, from 210 to 408 days of age of calves weaned at 72 (T72) or 210 (T210) days. Thirty-six non castrated Braford (5/8 Hereford 3/8 Nellore) calves were used. The average weight at the beginning of the experiment was 209 (T72) and 192 kg (T210). The whole feedlot period was 168 days, divided in four periods of 42 days. The roughage:concentrate ratio was 60:40 for the first and second periods, 50:50 for […]
