BIOAVAILABILITY OF CALCIUM CITRATE MALATE ADDED TO MICROBIAL PHYTASE-TREATED, HYDROTHERMALLY COOKED SOYMILK

Effects of microbial phytase on bioavailability of calcium added to co rn/soy diets were investigated in chickens, No effect (P > 0.17) of ph ytase was found for weight gain, feed intake, tibia/body weight, ash%, and ash Ca% when calcium citrate malate (CCM) was added to corn/soybe an meal and corn/hydrothermally cooked (HTC) soymilk diets, Using calc ium carbonate in corn/HTC soymilk diets, means for weight gain, feed i ntake, tibia/body weight, and ash% were less (P < 0.05) without phytas e, We hypothesize that CCM is less amenable to the formation of calciu m phytate complexes than are other calcium salts and, therefore, shoul d be more effective for fortification of soymilk products.
