Poultry products may be a source of foodborne human salmonellosis. The use alternatives to antimicrobials that are not harmful humans reduce the presence Salmonella spp. in poultry production. Among used, organic acids stand out. In present study, three different acid (OA) blends were evaluated for control Heidelberg (SH) commercial broilers. Day-old chicks (n = 114) randomly assigned four treatments, with replicates 12 birds each. Birds treatments A and B received SCFA (0.2mL/L) + MCFA (0.2mL/L), respectively, drinking water, while treatment C feed (2g/Kg feed). from D did receive OAs (control group). At 8 days age, each bird was orally inoculated SH at 108 CFU/mL, cloacal swabs enumeration cecal content performed 24-, 48-, 72-hours post-inoculation (hpi). results show reduction both shedding counts fed all pi times relative birds. Fecal significantly lower OA-treated groups compared group. As cecum, significant differences detected between 24 72 hpi, hpi. this study indicate feeding broilers contribute incidence production chain, allowing better flock health management, provided an efficient biosecurity program is employed.
