Abstract

Twenty-one Philippine native steers (Batangas strain) were slaughtered from a feeding experiment of fattening steers fed either a medium-energy ration or a high-energy ration (58% TDN and 72% TDN, respectively). Some steers were implanted with diethylstilbestrol (DES) and the others served as control. Of the 21 steers, 6 were slaughtered at approximately 160 kilograms, and 8 at 310 kilograms. The effect of slaughter weight on the carcass yield and physical composition were evaluated by the methods of complete factorial.

In general, as the steers progressed to heavier weights, chilled carcass weight, total carcass cut-up yield, total lean, total separable fat, and average yield of four major cuts were significantly (P<.01) increased. The separable fat and lean from four major cuts increased significantly (P<.05), while the total bone from four major cuts were not statistically significant as the steers increased in slaughter weight.
