 ¹+Diet: regular AIN-93G pelleted rodent diet adequate in vitamin A; −Diet: deficient AIN-93G pelleted rodent diet without vitamin A or vitamin D. One kg of the AIN-93 diet contains 4000 IU of all-trans retinyl palmitate. Skim milk was fortified with 147 IU/100 mL of retinyl palmitate.
²Each value is the mean ± SD. 𝑁 = 4 in the A/N group. 𝑁 = 5 in the other groups. Means in a row without common superscript letters are significantly different (𝑃<0.05).
