%X The chemical constituents of carcasses from 105 serially slaughtered bulls comprising Madura, Ongole, Bali, Grati (Friesian cross) and swamp buffalo were determined from ground rib joints from all animals and ground carcass sides from 48 bulls. Other carcass quality attributes were also assessed on each carcass. The bulls had previously been fed diets containing 85 or 30% concentrate for up to 280 days. Huxley's allometric equation was used in its logarithmic form as the basis for covariance analyses of the data. Rates of fattening on the 85% concentrate.diet, in decreasing order, were buffalo and Bali, Madura and Ongole, then Grati. There was a genotype by diet interaction for carcass protein, ether extract and energy in that the Madura bulls produced fatter carcasses on the high-concentrate but the leanest carcasses on the high-roughage diets. Buffalo carcasses were low scoring with small rib eye areas and high levels of subcutaneous fat, whereas the highest-scoring carcasses were those from Madura and Bali bulls. Genotype differences in daily carcass protein retention are discussed in relation to rate of maturing and also dietary influences.
