title: Growth rate, muscle protein composition, intestinal absorption of D-galactose and L-leucine and nitrogen balance in rats fed the raw legume Chamaecytisus proliferus L.
abstract: Growth rate, nitrogen balance, skeletal muscle nitrogen fractions and in vivo intestinal absorption of D-galactose (2 mM) and L-leucine (20 mM) have been measured in male growing rats (90-100 g initial body weight) fed 12% protein diets containing either casein (control) or the raw leafy legume Chamaecytisus proliferus L. (Western Canary Islands). As compared to control casein-fed rats, those fed the raw legume diet exhibited a significant reduction (P less than 0.01) in the rate of growth, nitrogen balance parameters, sarcoplasmic nitrogenous fraction of skeletal musculature and in vivo intestinal absorption of galactose and leucine; however, the non-protein nitrogenous fraction has been found significantly higher (P less than 0.01) than that of control animals, whereas the myofibrillar nitrogenous fraction remained unchanged. The possible nature of these findings is discussed.
