This study was carried out to investigate the effect of egg shell calcium salt types and egg shell membrane on calcium metabolism in rats. Sprague-Dawley male rats, 4 weeks of age, were fed on free-calcium diets for 2 weeks after adjustment period. Rats weighing approximately 247±2.3 g were divided into 6 groups and were fed on the experimental diets containing 0.2% calcium for 4 weeks. Experimental groups were as follows; [ES(M+)] (egg shell powder diet with egg shell membrane), [ES(M-)] (egg shell powder diet without egg shell membrane), [AC(M+)] (egg shell calcium acetate diet with egg shell membrane), [AC(M-)] (egg shell calcium acetate diet without egg shell membrane), [GC(M+)] (egg shell calcium glucuronate diet with egg shell membrane) and [GC(M-)] (egg shell calcium glucuronate diet without egg shell membrane).
