Calcium balance at different levels of digestible calcium and digestible phosphorus in weanling pigs

Recent studies conducted in our laboratory have determined values for standardized total tract digestibility (STTD) of calcium in feed ingredients fed to pigs. However, there is a lack of information about the requirement for STTD calcium in diets for pigs. Therefore, an experiment was conducted to measure calcium balance at different levels of STTD calcium in diets fed to 11 to 25 kg pigs.
