Use of organic acids to reduce Salmonella Typhimurium excretion in swine

The use of antimicrobials as growth promoters and disease prevention is being constantly reduced in several animal production systems, including the swine industry. Therefore, this study aimed to evaluate effectiveness using acidifiers control Salmonella Typhimurium 65-day-old pigs by detecting pathogen organs at euthanasia. For this, 24 piglets were divided into two experimental groups consisting 12 each. An untreated group (G1) a treatment (G2) received liquid organic acidifier drinking water for 10 days (D-5 D5). Five after start (D0), all challenged with 106 CFU assessed (D12). Every three (D3, D6, D9, D12), animals from each euthanized then submitted necropsy. Samples intestines (ileum, cecum, mesenteric lymph nodes, ileocolic nodes), liver, spleen, lungs collected isolate Salmonella. results show that, numerically, isolation G2 was lower than G1 that number positive cecum samples (66.7%; 8/12) statistically different models (16.7%; 2/12), reduction 28.6% total treated compared control. it observed product could reduce colonization Typhimurium.
