Bovine respiratory disease complex includes bacterial components, which cause the classic clinical signs of lethargy, depression, and fever, with variable nasal discharge, cough, or other signs. This bacterial component of BRD (most commonly Mannheimia haemolytica, Pasteurella multocida, Histophilus somni, and Mycoplasma bovis) may be treated with antimicrobial drugs designed to kill or inhibit the growth of the pathogenic bacteria.

The majority of food animal veterinarians do their best to make the most appropriate decisions for their clients' livestock. But there are times when we simply don't know what the best decision is. Likewise, there are times when a "new" procedure or "new" product is suggested by the client or one of our colleagues that we are unaware of or have not tried. Problem solving requires the use of multiple sources to educate oneself about the particular problem.

The issue of disease transmission between species is nothing new. Veterinarians have always been aware of the potential risk of wildlife being a source of disease transmission to livestock. A classic example is transmission of Leptospirosis species from wildlife to cattle via urine contamination of the environment.

The development and effectiveness of the standard milking time hygiene practices and dry cow therapy were established in the 1960's. Because of the effectiveness of these practices, mastitis has evolved on many farms to primarily environmental rather than contagious pathogens. The purpose of this article is to perform a literature review (especially trying to find studies published after the year 2000) as to the effectiveness of the various mastitis control practices in today's progressive dairy farm.

Many dairy producers use Rumensin? (Elanco Animal Health) in dairy heifers as an aid to controlling coccidiosis and for improved feed efficiency. Rumensin? also is approved for use in lactating cows as a tool for improving milk production efficiency. Monensin, the active compound in Rumensin?, has a very wide safety margin for humans and cattle. But, it can be toxic if not fed according to the FDA-approved label. In other species, such as horses, monensin can be extremely toxic.
