Effects of Microbial Phytase on Digestibility of Calcium in Calcium Supplements Fed to Growing Pigs
Both measures of calcium digestibility were higher for mono- and dicalcium phosphate than for calcium carbonate or products derived from seaweed or sugar beet, according to research at the Hans H. Stein Monogastric Nutrition Laboratory at the University of Illinois. The inclusion of microbial phytase increased the digestibility of calcium only in calcium carbonate.
