Abstract:

The present experiment examined the influence of three commercial organic acids, as an alternative to in-feed antibiotic, neoxyval, on broiler’s performance during pre- and post-challenge with Salmonella enterica subsp. typhimurium. Ten cages of birds received one of the following treatments: T1 = Control group, unmedicated, no bacterial challenge (+CONT); T2 = Negative control, unmedicated, challenged (-CONT); T3 = Medicated with antibiotic (neoxyval), challenged (NEOX); T4 = Supplemented with Gallimix, challenged (GALI); T5 = Supplemented with FormaXOL, challenged (FORMA); and T6 = Supplemented with Fysal, challenged (FYS). Chicks in treatments T2 to T6 were challenged with (3 × 10⁹ cfu/ml) of Salmonella enterica subsp. typhimurium on day 16. The results revealed that unchallenged bird (CONT) consumed more feed as compared to other treatments (P < 0.001). Furthermore, birds which had received NEOX, GALI, FORMA or FYS converted, feed more efficiently as compared to those which had received the negative control. This was an indication that organic acids used in this trial were able to restore the performance equally to the antibiotic (NEOX). The three organic acids were efficacious at reducing the Salmonella in ileum; however, FORMA and FYS eliminated the Salmonella totally from the ileum. Villus height but not the width was influenced by treatment (P < 0.01). In summary, the organic acids, which were used in this trial, reduced the Salmonella count and improved the morphology of the ileum as a result the cumulative FCR improved. The tested organic acids had a positive influence on the performance of broiler chickens, and could serve as a substitute to antibiotics.
