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.

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).

In most cases, we administer drugs at a different site than we want to drug to act. Understanding how drugs get to their site of action and how long they stay there is essential to making therapeutic decisions about which drug, what route, how much, how often, and for how long.

The design of antimicrobial regimens is addressed in the next section in these proceedings ("Antimicrobial Therapy: Regimen Design"), but the concepts within regimen design related to determining the concentration of drug required to inhibit growth of bacterial pathogens deserve a more thorough discussion. Antimicrobial susceptibility testing must not be viewed as a black box into which a veterinarian places a clinical sample of an infected site and receives a "yes" or "no" from the diagnostic laboratory.

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.
