Replacement heifer development is a critically important area for veterinarians to offer production medicine advice to their beef-producing clients. In order for replacement heifers to calve at approximately 24 months of age and to reach puberty the equivalent of three heat cycles before the start of the mature cow breeding season, heifers must become puberal by 11 to 13 months of age.

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.

These proceedings present data related to the question of how long to wait after administering a single injection antimicrobial before applying success/failure criteria. More accurately, we will evaluate success/failure and mortality data based on administering a uniform regimen and then waiting different periods before applying success/failure criteria, and the animal subsequently being eligible for further therapy.

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.

Pathogens differ in their virulence, contagiousness, and their modes of transmission. These differences exist not only between pathogens, but for virulence and contagiousness, can also differ between strains of the same species of pathogen.

Although we have known the importance of internal parasites in cattle for many years, we still face an endless battle to control these organisms. Parasites are the ultimate "survivor". Parasites realize that their survival is dependent on not killing their host. As a result, they have adapted as their hosts (cattle) are exposed to different management practices (including parasiticide products and pasture management practices).

Many veterinarians express frustration when trying to provide their clients with the best advice on which diagnostic tests to recommend for purchased cattle or the resident herd. The goal is to screen apparently healthy cattle to identify carriers of infectious disease that could cause reproductive losses and other health problems in the herd.

Productivity for beef cattle herds has been shown to be increased when a high percentage of heifers become pregnant early in the first breeding season. A producer's heifer selection and development program should result in most heifers in the replacement pool reaching puberty at least 42 days prior to the start of breeding because the conception success to first service is lower on the puberal estrus compared to the third estrus.
