Effect of raw legume diets on intestinal absorption of D-galactose by chick

The effect of four raw legume diets on the intestinal absorption of D-galactose and oxygen consumption were studied in chick. Field beans (Vicia faba), soybeans (Glycine soja), bitter vetch (Vicia ervilia), and navy beans (Phaseolus vulgaris), were used. The intestinal absorption was determined by both in vivo and in vitro techniques. In vivo, only navy beans and soybeans inhibit intestinal transport of D-galactose, while in vitro all the diets do. Oxygen consumption by intestinal rings increases in chicks fed on bitter vetch diet.
