The effect of vitamin C on iron (FeS04 x 7 H2O) absorption in chickens was assessed. The degree of iron and vitamin C absorption was determined by the perfused intestinal loop in vivo method. Vitamin C decreased iron absorption in the jejunum from 3.43 mg per 1 cm2 within 60 min. to 1.10 mg and in the caecum from 4.94 to 3.08, respectively. A significant increase of vitamin C absorption from 2.6 mg per 1 cm2 within 60 min. was found in the jejunum, and in the caecum from 4.1 mg to 13.35 mg. Some interaction between iron absorption and the presence of vitamin C in chickens was observed.
