Omitting the vitamin and trace mineral premixes and(or) adding 2/3 less supplemental
inorganic phosphorus source (from .55%
down to .40% total P) to diets during late
finishing (191 to 265 lb) had no effect on
growth 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.
