Pigs were allocated to 2 diets, NP (17, 15, and 15%
CP for the starter, grower, and finisher phases, respectively)
or LP (20% CP reduced relative to NP for each
phase), each of which contained a basal or a supplemented
AA profile. This resulted in 4 dietary treatments:
Low protein - basal amino acid diet, low protein- supplemented
amino acid diet, normal protein - basal amino
acid die, and normal protein - supplemented amino
acid diet. Each diet was fed to the pigs in both sanitary
regimes resulting in 8 treatment groups.
