The objectives were to evaluate diets containing levels of in natura linseed oil (1.0, 3.8 and 5.2% of diet DM) on carcass characteristics and meat cuts, and correlate these results with in vivo body measures of 14 heifers and 15 steers Nellore x Canchim. The animals were confined individually receiving 20% of sugar cane as roughage and 80% concentrate, in a complete randomized block (oil content x sexual condition). All animals of each block were slaughtered when the average body weight reached 500 kg. No interactions between treatments were observed. Add up to 5.2% of linseed oil in diet of crossbred cattle increases the weight of the main carcass cuts, reduce the loss during cooling and does not change the level of renal pelvic-inguinal fat. Heifers and steers Nellore x Canchim produce similar amounts of weight and yield hindquarters meat. Along with body weight, the extent pelviano contour is the most indicated to assist the formation of homogeneous lots for slaughter or trial, because showed the best correlation with the characteristics used in the Brazilian market of meat, such as weight and carcass yield.(AU)
