<b>Cuts of dairy-origin cattle fed mesquite pod meal in replacement of corn

Abstract

This study was carried out in order to assess commercial front and rear cuts of dairy-origin cattle fed mesquite pod meal. Twenty-five non-castrated male bovines (Holstein-Zebu), distributed according to a completely randomized design, with five animals per treatment, were used. The feed contained about 121.2 and 544.98 g kg-1 of crude protein and total digestible nutrients, respectively, and was composed of tifton grass hay, cornmeal, soybean meal, mesquite pod meal and mineral salt. The right half carcass of each animal was separated between the 5th and 6th ribs, in front and rear quarters, from which commercial cuts were obtained. There was no effect (p > 0.05) as to the replacement of corn for mesquite pod meal on the weights and yields of front cuts (shoulder, brisket, chuck, hump and flanks) and rear cuts (tenderloin, shank, knuckle, thin flank, flat, eye round, rump tail, top side, cap of rump, rump, cut of rump, striploin, cap of cube roll). Mesquite pod meal can substitute cornmeal in 100% in the concentrate without changes in weight and yield of the commercial front and rear cuts of male bovines of dairy origin.
