SPECIAL STORY FEED & ADDITIVE MAGAZINE September 2022 45 ination. After slaughter, the poultry food product and equipment can be cleaned using various antimicrobials through either air or water chilling. Air chilling consists of hanging the carcasses individually and allow rapid air movement to reduce the temperature of the product. This process reduces the risk of cross contamination since each carcass is chilled individually. Water chilling consists of submerging the carcasses in a chilled water current with an antimicrobial for a set amount of time. The preventative measures in water chilling include: chlorine (less common now with current legislation) and organic acids. The methodology of chilling used is dependent on the regulatory agency and consumer preference. A COMPREHENSIVE SOLUTION Because of the potential for contamination all along the production process, achieving “zero Salmonella” requires a comprehensive strategy: • No matter the quality of the raw materials, it is strongly recommended to use a feed hygiene strategy that can reduce Salmonella contamination, like an organic acid. By applying Biotronic to the feed, contaminant load going to poultry facilities can be reduced. • Within the poultry gut, providing ‘competitive exclusion’ throughout the gut to deprive Salmonella of places to colonize as well as improving dietary nutrient utilization to also deprive Salmonella of the food source are key to prevent colonization, proliferation, and translocation to other organs. The combination of PoultryStar, a synbiotic (prebiotic and probiotic) containing probiotic bacteria isolated from throughout the poultry’s intestinal tract, along with Symphiome, a precision glycan improving nutrient utilization through microbial protein metabolism. Since PoultryStar contains gut bacteria from poultry, it can be given as early as the hatchery and throughout grow-out to ensure continuous protection. Symphiome removes the excess protein in the hindgut of the bird which acts as a food source for pathogens, like Salmonella, and can be added to all phases of the poultry diet. • Intestinal integrity and microbial balance can both be altered with improper vitamin supplementation and the presence of mycotoxins. Providing proper vitamin levels through OVN and controlling mycotoxins through MycoFix reduces inflammation in the gut as well as microbial dysbiosis, reducing the incidence of pathogen colonization.
