Abstract
Dietary partially destoned olive cake supplementation on performance, carcass traits and meat quality of intensively finished bulls was evaluated. Forty-five Limousin bulls, divided into three homogenous groups, received a diet with no supplementation (Control-CTR), 7.5% (Low Olive Cake-LOC), and 15.0% of olive cake supplementation (High Olive Cake-HOC). The trial was realized for 150 days; all bulls were individually weighed at the beginning, middle, and end of the trial, to calculate the individual average daily gain (ADG). At slaughtering, on each carcass, hot weight was recorded and, after 7 days, the pH and temperature were measured. On Longissimus lumborum muscle, color, cooking loss, and shear force of the cooked sample were determined. The chemical composition and the fatty acid content of muscle were determined. Olive cake inclusions (7.5% and 15.0%) increased (p < 0.05) the body weight, ADG, slaughter traits and intramuscular fat content and influenced (p < 0.05) the quality indices. The 15.0% of the inclusion reduced (p < 0.05) the cooking loss and shear force, and increased the unsaturated fatty acid content. The olive cake can be considered as a functional component in beef production and, in substitution to a quote of cereals into the diet of bulls, could be an opportunity to improve agriculture sustainability.
