Omitting vitamin and trace mineral premixes, and(or) reducing inorganic phosphorus during late finishing did not affect growth performance, carcass traits, or muscle quality

Omitting the vitamin and trace mineralpremixes and(or) adding 2/3 less supplementalinorganic phosphorus source (from .55% down to .40% total P) to diets during late finishing (191 to 265 lb) had no effect ongrowth performance, carcass characteristics, or muscle quality in high-lean pigs. Thus, this concept can be used to decrease the cost of feeding terminal-cross pigs to heavy weights, while decreasing excretion of minerals from intensive swine operations.
