Use Of Dietary-Fat To Reduce Dust, Aerial Ammonia And Bacterial Colony-Forming Particle Concentrations In Swine Confinement Buildings

ABSTRACT AN experiment was conducted to determine the effect of dietary fat on pigs and air quality of swine confinement buildings. Addition of tallow to the diet improved pig performance, and reduced aerial and settled dust concentrations. Aerial ammonia concentrations and the numbers of BCFP were lower (60 and 75%, respectively) in the building in which the diet containing 7.5% tallow was fed.
