Standardized total tract digestibility of phosphorus by pigs

Dr. Hans H. Stein explains the different ways of calculating phosphorus digestibility and discusses the advantages of using standardized total tract digestibility values. Dr. Stein also presents findings on the use of microbial phytase in swine diets to increase phosphorus digestibility, eliminate the need for supplementation with dicalcium phosphate, and decrease excess phosphorus excretion.
