Liver retinol concentration (A), content (B), and serum retinol concentration (C) in male gerbils fed maize with different VA and milling treatments (study 1). Liver samples were saponified during the analysis; therefore, retinol represents (retinol + retinyl esters) present in the liver. All groups included 10 gerbils for final measurements except the midline whole (n = 4) and refined (n = 3) groups. All values are means ± SDs. Treatment data were analyzed with the use of 2-factor ANOVA. Groups without common letters were significantly different: a > b > c. P < 0.05 was considered significant. Midline statistical difference between refined and whole groups was determined with the use of a 2-sided t test. VA, vitamin A.
