Effect of Tannin and Amenia on Dietary Iron Absorption and Some Physiological Features in Male Rate

This study was conducted to investigate the effect of Tannin and anemia on dietary iron absorption and som physiological features in weanling albino male rats, Forty eight rate were used as a biological model for this study. These rats were randomly divided into two major groups (Anemic and Healthy). First group get anemic by induce bleeding from Retro-ocular vein. Each major group contains 24 rats were divided into 4 group, each subdivided group fed one type of diet (4 types of diets were used: Standard Diet, Basic Diet with Tannin, High Density Diet and Low Density Diet). Those diets fed to rats for 10 days, then estimation of dietary iron absorption and nutritional status were performed for anemic and healthy rats by estimating Hemoglobin concentration, Body weight changes, Diet and dietary iron intake weights, And eliminated feces and fecal iron weights, Analysis of variance showed that anemic rats absorb iron more than healthy one, Tannin decrease iron absorption in both anemic and healthy rats. Finally, high density diet is more efficient than other diets in improving nutrition status in anemic rats.
