Effect of different different steam-flaked grains on insulin/glucose ratio in weaned foals. CG: Corn group (n = 6); OG: Oats group (n = 6); BG: Barley group (n = 6). †indicates that the BG was significantly higher than the CG (P < 0.05); ††indicates that the BG was highly significantly higher than the CG (P < 0.01). ‡ indicates that the BG was significantly higher than the OG (P < 0.05); ‡‡ indicates that the BG was highly significantly higher than the OG (P < 0.01)
