EVALUATION OF ALTERNATIVE MINERAL AND BIOMINERAL BEDDING AMENDMENTS FOR THE CONTROL OF SALMONELLA spp. IN POULTRY LITTER

Abstract

Modern poultry farming is a strategic sector in agribusiness, supported by genetic, technological, and management advances. Poultry litter, composed of materials such as wood shavings and agricultural by-products, contributes to animal welfare, feed efficiency, and biosecurity by controlling moisture, providing thermal insulation, and reducing contact with feces. Salmonella spp. represents a significant health risk, transmitted both vertically and horizontally, with survival influenced by environmental factors, litter composition, and management practices. This study evaluated the efficacy of litter conditioners in mineral and biomineral formulations in reducing Salmonella. Samples were inoculated with 10⁶ CFU/kg and treated with 25, 50, and 125 g of product, analyzed on days 1, 15, 30, and 45 according to ISO 6579. Initially, Salmonella was detected in all samples but was not recovered by day 45, including the positive control, indicating a possible natural decline of the bacterium, environmental influence, and methodological limitations. The results demonstrate that the application of litter conditioners, combined with proper litter management, plays an important role in maintaining biosecurity, controlling pathogens, and preserving optimal conditions for the welfare and performance of poultry, highlighting the relevance of integrated litter management for sustainable poultry production.
