This website is a sister-site to Dairy Herd Management meaning there will be many articles that have crossover between the two sites. The important difference, however, is that Bovine Veterinarian Magazine targets topics towards cattle in general as opposed to specifically dairy cattle. There are many articles discussing antibiotic resistance that can be very helpful for those looking for better understanding of drugs in cattle.
This organization works to provide veterinarians the latest information regarding the treatment and care of dairy cattle. They have many newsletters and protocols that can be accessed to aid in the understanding of many dairy cattle topics, including proper use of antimicrobials for treatment.
