The feedlot performance of Red Angus steers, with initial age of eight months and 189 kg of initial live weight, fed to reach the slaughter weight (SW) of 340, 370, 400 or 430 kg, was evaluated. The number of days to reach the respective weight was 114, 144, 168 and 209 days, with 12, 13, 14 and 15 months of age. The animals were fed with a 13.13% crude protein diet, and roughage:concentrate ratio of 56:44. The average daily gain […]
