Growth of carcass tissues in grazing nursing calves supplemented or not

摘要

Brazil has been standing out in the world market as a large meat exporter.Despite this,the meat quality produced in pasture based production systems has been widely criticized.The main negative point is the reduced carcass fat deposition.Carcass fat has a double effect in guaranteeing meat quality : protection against cold shortening and,it is responsible for the softening and flavor of the main commercial cuts.Carcass composition begins to be defined by the tissues formed in the initial phases of life.In this context,the objective of this study was to evaluate the growth rate of carcass tissues in grazing nursing calves,supplemented with different protein concentrated rations.
