Desempe？o productivo, tipificación y rendimiento a la faena de machos enteros jovenes Holando Argentino engordados a corral

productive performance, carcass grade and yield of feedlot-fed holstein argentino young bulls and steers have been compared. all the animals were slaughtered before 2 years of age. young bulls had average daily gains 12,9% greater than steers and 14,9% greater feed efficiency. carcass yield of intact males was 2% higher than steers, and obtained a higher proportion of fat type 1. this study shows that young bulls have a better productive performance than steers. age, nutrition and management of animals have reduced the importance of potential disadvantages. the existence of a new category of slaughter in argentina called mej (young intact male) will provide higher yielding and heavier carcasses.
