The site of absorption of calcium from the intestinal tract of growing pigs

Caroline González-Vega is a Ph.D. candidate in the Stein Monogastric Nutrition Lab. She describes an experiment to determine the effect of the level of calcium and the level of phytate in the digestibility of calcium in inorganic (calcium carbonate) and organic (Vistacal) calcium sources, and the site in the gastrointestinal tract where calcium is absorbed for the two sources.
