Cross-Section Observational Study to Assess Antimicrobial Resistance Prevalence among Bovine Respiratory Disease Bacterial Isolates from Commercial US Feedlots.

Antimicrobial resistance (AMR) is a global public health threat that jeopardizes efficacy of antibiotics in veterinary and human medicine. Antibiotics are commonly administered to target the bacterial component of bovine respiratory disease (BRD). The objectives of this study were to obtain a better understanding of antibiotic resistance in BRD-associated bacteria (, and ), investigate the clinical significance of AMR by monitoring clinical outcomes, and determine if regional differences exist in AMR trends.

Feedlot Processing and Arrival Cattle Management.

Acclimating newly arrived cattle in a feedlot setting can increase cattle confidence, reduce stress, improve immune function, and increase cattle well-being. Understanding cattle instincts and using low-stress handling techniques teaches cattle to trust their caregivers and work efficiently for them throughout the feeding period. These techniques should be applied with newly arrived cattle when they are unloaded, moved from the holding pen to the home pen, and handled inside the home pen.
