Introduction Obtaining satisfactory production rates as well as welfare of pigs depends on adequate energy and nutrient supply, and among these nutrients phosphorus has deserved special attention. Phosphorus is a critical element for body protein accretion because of its involvement in the energy metabolism, synthesis of nucleic acids, and structure of cell membranes. Muscle tissue contains...

The level of 0.464% of Pd would, in principle, be above the requirements of the pigs in the studied phase. An important aspect considered, was the maintenance of the ratio calcium: Pd of the rations
