      The purpose of this study was to evaluate the effects of a dietary added formaldehyde-propionic acid blend on feed enterobacteria counts and on growing pig performance and fecal formaldehyde excretion. Forty pigs (34.2±1.8kg BW) were used in a randomized complete block design experiment with four treatments, five replications per treatment and two animals per experimental unit (pen). The treatments were: 0.0, 1.0, 2.0, and 3.0g of blend kg-1 of feed. No effects (P>0.05) of dietary added blend levels were observed on average daily gain, average daily feed intake and feed:gain ratio during 1 to 14 and 1 to 28 days of experiment. Increasing dietary levels of blend reduced quadratically (P0.05) of blend on fecal formaldehyde excretion on the 28th day of the experimental period. Therefore, the addition of dietary formaldehyde-propionic acid blend up to 3.0g kg-1 of feed reduces the Enterobacteriaceae counts until the 14th day after feed mixing, without any effects on growing pig performance and fecal formaldehyde excretion
