The Phase 1 diet was fed at 1.8 kg/pig and the Phase 2 diet was fed at 5.5 kg/pig.
SBM = soybean meal.
Dietary treatments of medium SBM for Phase 1 and 2 were created on the farm by blending a portion of low- and high-SBM diets of the respective phase using an automated feeding system.
FTU = phytase units.
DDGS = distiller's dried grains with solubles.
