The Effects of Supplementing Weanling Pig Diets with Organic and Inorganic Acids on Growth Performance and Microbial Shedding

Abstract

One hundred and eighty pigs were weaned at an average of 18.2 days of age and were assigned to one of five dietary treatments. Pigs were allotted based on genetics, sex and initial body weight. Treatments were as follows: A) Basal diet, no antibiotics (negative control); B) Diet A plus Carbadox at 45.4g/ton (50 ppm; positive control); C) .4% Organic acid blend, added to diet A by substituting for corn; D) .2% Inorganic acid based blend, added to Diet A by substituting for corn; E) Combination of .4% organic and .2% inorganic acid based blends, added to Diet A by substituting for corn.
