Abstract


This research is subscribed of an extensive project that has as main objective the production of crossbred specialized beef hybrids from reformed Romanian Black Spotted cattle's with bulls from breeds specialized for meat production (Blue Blanch Belgique, Aberdeen-Angus and Limousin). Averaged biochemical indicators analyzed showed a normal state of animal's health. The obtained half-breeds products (bulls) were raised under semi-intensively conditions and slaughtered at 12 months of age. Live weight, back-fat thickness and carcass traits were significantly influenced by breed, all fat parameters being lower at this age than at standard minimum age of slaughter for meat production (18 months). Drip loss and chemical composition were similar for the breeds. The meat was lighter and pH24 values of longissimus muscle were between 5.57 and 5.64. Sensory panel tenderness and Warner-Bratzler shear force values indicated tougher meat at RBSxAA than at RBSxL1 or RBSxBBB. Differences in meat quality were probably due to the combined effects of brute chemical composition and pH dynamic during ripening. It is concluded that slaughtering steers at younger ages may require supplementary feeding, being recommended a slaughter age between 18 and 25 months old.
