Insulin tolerance test of AA broilers and Silky fowls. (A) Control groups (n = 6/breed) were injected with an equal volume of PBS after 12 h fasting. (B) Experimental groups (n = 6/breed) received an injection of insulin (80 μg/kg BW). In the same breed, different letters indicate P < 0.05, and the same letter indicates P > 0.05. In the same time point, * means P < 0.05 between two breeds, no * means P > 0.05.
