This experiment was conducted to compare the impact of corn and barley on growth performance, meat quality, and muscle fatty acid (FA) composition of goat kids. Twenty-four Boer males (25.1 ± 1.5 kg) were blocked by body weight and allotted randomly within block to one of three experimental diets. Treatments consisted in varying ratios of barley to corn in the concentrate: (1) 100:0, (2) 50:50, and (3) 0:100. Fifteen randomly selected kids (n = 5 kids per treatment) were slaughtered and longissimus thoracis et lumborum was collected. Inclusion of barley in the diet linearly increased concentrate intake (P < 0.01) and tended to increase average daily gain (P = 0.08). There were no significant differences on carcass traits and meat quality among treatments. Levels of n-3 and n-6 FA increased linearly (P < 0.01), whereas n-6:n-3 ratio linearly decreased (P < 0.01) as corn inclusion in the diets increased.
