222 Corn-expressed Phytase Modulates Serum Amino Acids and Proteomics Profiles in Nursery Pigs Fed with Low-protein, -calcium, and -phosphorous Diets

Abstract Feeding pigs with very low-protein (VLP) and low-phosphorous (P) diets may be useful for decreasing the nutrients excretion to the environment; however, this practice negatively impacts the animals’ growth performance. A beneficial effect of corn-expressed phytase (CEP) on growth performanc...
