Abstract

We evaluated carcass characteristics, weight and percentage of prepared commercial cuts of the primal pistol cut (PC) of 30 young crossbred bulls fed diets which included replacement levels (0, 25, 50, 70 and 100% of the dry matter, DM) of corn by babassu mesocarp bran (BMB). The experiment was a completely randomized design with six replicates. Slaughter weight was not affected by treatments. Hot and cold carcass weights decreased linearly (P<.05) at 230 g and 250 g, respectively, for each 1 kg of replacement, and hot carcass yield (HC) decreased by 3.2 g/kg of HC for each 1 kg of DM of BMB in the diet (P<0.05).  Subcutaneous fat thickness presented a quadratic (P<.05) response with maximum point estimated by the regression equation of 4.29 mm with 33.3% substitution. The proportion of PC of the carcass increased linearly as levels of BMB in the diet increased (P<.05). The percentage of side cut showed a quadratic response (P<.05), with maximum point estimated with 33.3% substitution. The weight of the prepared commercial cuts of the PC, striploin, knuckle and eye round, and the percentage of tenderloin, topside and shank, were influenced by the diet (P<0.05). There was no change in prepared meat cuts yields of PC (73.22%) (P<.05). The use of babassu mesocarp bran to replace corn in cattle finishing diets does not affect the weight and meat yield of the pistol cut, but decreases linearly hot carcass weight, and subcutaneous fat thickness at replacement levels above 33.3%.
