The sample were 180 cattles and this samples were divided into 3 groups, each group contain 3 different breeds (PO, LIMPO, and SIMPO). Every breeds divided into 2 subgroups based on sex and on age (1.5-2.0 years old; 2.5-3.0 years old; and more than 4.0 years old). Data were collected for slaughter’s weight, carcass’s weight, carcass’s percentage, and physical also chemical quality of Longissimus dorsi (LD) muscle. Data were analized using a complete randomized design (CRD) with factorial design: 3X3X2 factorials and subsequently continued with Duncan’s new multiple range test. The results showed that breed and age had very significant differences (P<0.01) on slaughter’s weight, carcass’s weight, and carcass’s percentage. Sex of PO, SIMPO, LIMPO had significant differences (P<0.05) on slaughter’s weight and carcass’s weight. Chemical quality of meat showed that age and sex had significant differences (P<0.05) on moisture and fat contents. The conclusion was breed of LIMPO produced more carcass than PO and LIMPO but PO had better chemical quality than SIMPO and LIMPO.
