Effects of potential Tylosin substitutes on Salmonella prevalence and the microbiome of subiliac lymph nodes of beef feedlot cattle
Tylosin, a macrolide antibiotic, is fed to feedlot cattle for liver abscess prevention. Tylosin alternatives are currently being investigated as pressures to reduce the amount of antibiotics used in livestock increase. Understanding effects of various feeding strategies on the safety of beef products is a priority as alternatives are investigated. This study investigated the effect of Tylosin, and two Tylosin alternatives on the prevalence of Salmonella in subiliac lymph nodes (SLN) and the microbiome of SLN from feedlot cattle. Salmonella harborage in the lymph node is a challenge for the beef ...
