Two experiments were conducted to evaluate the efficacy of feeding an E.coli derived phytase to pigs fed phosphorus deficient,cornsoybean meal diets.In Exp. 1,120 crossbred piglets (9.53 ± 0.84 kg)were allocated to one of five treatments which consisted of four low phosphorus diets (0.61% Ca, 0.46% total P and 0.24% non-phytate P)supplemented with 0, 500, 1,000, or 20,000 FTU/kg E. coli phytase as well as a positive control formulated to be adequate in all nutrients (0.77% Ca, 0.62% total P and 0.42% non-phytate P).
