Fifty Limousine (LI, initial age 219 days and live weight 249 kg) and
fifty Retinta (RE, initial age 220 days and live weight 254 kg) were purchased
from several commercial farms specializing in the production
of purebred breeding animals, and then transferred to a commercial
feedlot. The calves were reared in a semi-extensive regime together
with their mothers on pasture and suckled and grazed until weaning
(at approximately 8 months of age).
