Results are expressed as mean ± SD for each group (n = 8). Feed efficiency = [weight gain (g)/food intake(g)] × 100%. C: control diet; CS: control diet +5% high molecular weight chitosan; DM: diabetes + control diet; DM + TZD: diabetes + control diet + 0.8 mg/kg thiazolidinediones (rosiglitazone); DM + CS: diabetes + control diet + 5% high molecular weight chitosan.
