Effect of tylosin exposure or exclusion on liver abscess prevalence, fecal pathogen populations, and the microflora of finished beef products from feedlot cattle, The
There is great pressure to reduce use of, and find alternatives to, antibiotics in animal production. More than 70% of feedlot cattle in 1000+ head lots are currently exposed to tylosin phosphate, a macrolide antibiotic used for the reduction and prevention of liver abscesses. As such, its potential removal from cattle feeding strategies could have a marked impact on both the economics of the beef industry and food safety. Additionally, little is known about the effect of tylosin exposure or exclusion on the microbiome of finished beef products. In light of these facts, a blinded, randomized, ...
