The experiment described evaluated the effect of a commercial in-feed preparation (Bio-Add™) involving a mixture of formic acid and propionic acid on the incidence of experimental fowl typhoid in groups of 41 and 42 1-wk-old Rhode Island Red chickens. The chickens were infected through contact with 12 identical chickens that had been inoculated orally with 10 8 cfu of Salmonella gallinarum strain 9. The incidence of mortality and morbidity due to fowl typhoid was 31/41 (76%) in birds given untreated feed and 14/42 (33%) in birds given feed treated with Bio-Add™.
