Campylobacter carriage in the cloaca of chickens after a long period of use of malic acid. Two week old partridge chickens (A) and AA broilers (B) were provided with the malic acid-supplemented drinking water for 3 weeks and cloacal swab samples were collected at the designated time to determine the Campylobacter carriage. Twenty chickens were assayed in each group, the data are presented as the mean ± SD, and asterisks indicate significant differences (p < 0.05 *).
