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.

One can usually find many sources of information about drugs: FDA website, drug company websites and technical reports, VIN, journals, trade magazines, and so on. The important skill required of veterinarians is to assess that information to determine its usefulness in your daily practice. Below are some principles of evaluating drug information, with the goal of improving treatment and the practice of medicine.

The science of how drugs work on the body (or the microorganism or parasite) is pharmacodymanics (its counterpart being pharmacokinetics, how the body works on the drug). In this section, the basic concepts of drug concentration and drug action are followed by a review of the mechanisms of action of the major drug groups used in food animal practice including NSAIDs, glucocorticoids, reproductive drugs, antimicrobials, and parasiticides.

Dealing with a sick cria and an anxious client can be quite daunting at times. This task becomes less daunting when one understands the main problems and how to manage them. Neonatal crias are typically admitted to the UT College of veterinary medicine due to prematurity/weakness/inability to stand, suspected or real failure of passive transfer (FPT), and septicemia.

Mycobacterium avium subspecies paratuberculosis (MAP), the causative agent of Johne's Disease (JD), is prevalent worldwide. The NAHMS Dairy 1996 study, estimated 21.6% of the dairy herds in the US were infected with MAP, resulting in annual economic losses for the dairy industry of $200-250 million.

Maybe this doesn't really fit "common" but it is always interesting to hear about cases. The main thing about rabies in cattle (and other species) is that signs are quite variable and inconsistent. Certain signs should be "red flags" for bovine rabies. Oftentimes cattle with rabies will have some history of hindlimb ataxia, weakness, or paralysis (this in itself is typical of many bovine diseases but for cattle exhibiting these signs, rabies should be considered).

Bovine viral diarrhea virus (BVDV) is one of the most important infectious agents of cattle. The annual economic loss caused by BVDV is difficult to quantify but certainly is significant. The insidious nature of BVDV combined with the biology of the virus and complex disease pathogenesis has made control and prevention of this virus challenging.

More than 60 years ago an enteric disease of cattle was described in North America that was characterized by outbreaks of diarrhea and erosive lesions of the digestive tract.17 The disease was called bovine viral diarrhea virus or BVD. The virus causing BVD was named bovine viral diarrhea virus (BVDV).

Traditionally, we have assumed that if a bacterial pathogen is "susceptible" to an antimicrobial, we just use the dose on the bottle or in a formulary, and the infection will be eliminated. The increasing incidence of "resistant" pathogens, i.e., pathogens requiring high concentrations of antimicrobials such that they become untreatable, has focused attention on identifying ways to reduce the selection for resistant organisms.
