Incidência de Salmonella spp. em cama de aviário tratada com BAC TRAT® 2A

Abstract

This work evaluated the effect of the biological modulator BAC TRAT® 2A added to poultry litter in reducing the incidence of Salmonella. The study obtained samples from two aviaries in the western region of Paraná, and the experiments were carried out from January to October 2023. Three litter samples were collected from each aviary, the first being in the batch interval and before applying the product biological: the second collection 10 to 15 days after the application of the BAC TRAT® 2A product and after housing the birds and, the third collection 40 to 45 days after the application of the BAC TRAT® 2A product and after housing the birds. The Miniaturized Most Probable Number methodology was used to quantify Salmonella colonies. Samples were enriched with peptone water and Rappaport broth, then streaked in petri dishes with Salmonella- Shigella Agar (SS). The results demonstrated 91,36% and 92,45% reduction in NMP ml-1 of the analyzed poultry houses.
