* BL; bilirubin. All rabbit groups received standard basal diet without (group I) or with 10 mL lettuce juice supplement (groups II–IV). Lettuce juice (10 mL) was prepared from lettuce cultivated without (group II), nitrate fertilization (group III), or WPH (group IV) equivalent to 2.5, 11.16, and 3.86 mg/kg bw/day, respectively. ALT: alanine amino transaminase; AST: aspartate amino transaminase, ALP: alkaline phosphatase.
