  1. The broilers were fed a diet either or not supplemented with a butyrate containing feed additive in a concentration of 3 g/kg of sodium butyrate radical. Each dietary treatment consisted of 1 pen of 20 broilers. Measurements of SCFA concentrations were done at the age of 21 days after 4 days of Salmonella infection.
  2. Significant differences for SCFA concentrations or percentages among dietary treatments are indicated with different letters per row (a, b, c, d, e).
