This study was conducted to investigate the bioavailability of calcium derived from starfish as a new calcium source. Four-week old Sprague-Dawley female rats were divided 6 groups. The rats were received experimental diets containing two kinds of Ca sources, CaCO₃ or starfish, and three levels of Ca, low (0.1%), medium (0.5%) and high (1.0%), respectively, for 6 weeks. The parameters which related to Ca bioavailability were measured : Serum Ca concentration, Alkaline phosphatase(ALP) and GOT activities ; tissue Ca contents, bone dimension and Ca, P, Mg contents ; Ca retention and apparent absorption.
