aChallenged orally with 107 CFU/chick. Trial 1 day 1, Trial 2 day 7.
bIn Trial 1, 0.05% of an organic acids blend (30% of formic acid and 18% of propionic acid) offered in drinking water from 1 to 7 days and from 15 to 21 days of age, associated with a treatment with 3 kg/ton of a product with minimum 92% of fumaric and benzoic acids in feed, from 1 to 21 days of age. In Trial 2, a product constituted with coated 89% of calcium butyrate at 2 kg/ton in feed from 1 to 21 days was evaluated.
