1Results are presented as mean and SEM. Labeled means in a row without a common superscript letter differ, P < 0.05. AKP, alkaline phosphatase; CON, piglets fed a basal diet; Diquat, piglets fed the basal diet and challenged by diquat; DCGA, piglets fed the basal diet containing CGA (1,000 mg/kg) and challenged by diquat.
