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.
