Values provided represent means that have been deemed statistically significant at (P < 0.05). SEM = standard error of means; AT = ambient temperature; TN = thermoneutral temperature; TC = total cholesterol; LDL = low-density lipoprotein cholesterol; HDL = high-density lipoprotein cholesterol; TG = triglyceride; AST = aspartate aminotransferase. n = 10, 10 birds per treatment (2 birds per duplicate, 1 male and 1 female).
