Muscle fatty acid composition and thiobarbituric acid-reactive substances of broilers fed different cultivars of...

Two experiments were conducted to evaluate the production parameters, muscle fatty acid composition, and lipid stability of birds fed four different cultivars of sorghum. Experiment 1 used ruby red and valpo red, and Experiment 2 used kinsman and mason cultivars of sorghum. The basal diet was a corn, soy, and flax meal, and sorghum cultivars were substituted at 10 or 5% in Experiments 1 and 2. No significant difference was observed for BW, feed consumption or feed efficiency (P > 0.05). The total lipids were reduced (P < 0.05) in the leg muscle of broilers fed the mason cultivar. The TBA-reactive substances (TBARS) were lower (P < 0.05) in the leg muscle of birds fed the mason cultivar when compared to kinsman or control diet. The content of n-3 polyunsaturated fatty acids were higher (P < 0.05) in the breast and leg muscles of birds fed ruby red, kinsman, and mason cultivars of sorghum.
