Carbohydrate metabolism of growing pigs fed low-protein diets. Glucose (A), pyruvate (B), insulin(C) and glycogenic amino acid (D). Values are means of 6 observations per treatment. *Significant differences between treatments (P ≤ 0.05), **Significant differences between treatments (P ≤ 0.01). Values are least squares means ± SD; n = 6. Abbreviations: W LP, waxy corn starch low-protein diet; C + W LP, corn starch + waxy corn starch low-protein diet; C LP, corn starch low-protein diet; P + W LP, pea starch + waxy corn starch low-protein diet; P LP, pea starch low-protein diet
