Performance, carcass yield, and carcass quality characteristics of steers finished on rhizoma peanut (Arachis glabrata)-tropical grass pasture or concentrate.

摘要: Steers (n = 156) finished on rhizoma peanut (Arachis glabrata Benth.)-tropical grass pasture in Florida and slaughtered at Central Packing, Center Hill were compared with steers 152) a concentrate diet Texas Excel, Plainview. Average daily gain during the growing finishing periods was lower (P .10), but quality grade slightly better (low Select vs mid ; P <.01) for concentrate-finished steers. Lean color of forage-finished darker <.001) fat had creamier <.001), carcasses not discounted due to yellow color. Shear force values higher (6.8 4.0 kg than Off-flavors detected by trained sensory panelists 36% 14% carcasses, all barely detectable levels. This research indicates that can be peanut-tropical pastures, some reduction relative Fat off-flavor problems often associated forage-finishing do seem major concerns when are peanut. However, dark lean poor tenderness may reduce beef produced this forage.
