A comparison of florfenicol and tulathromycine for the treatment of undifferentiated fever in feedlot calves.

The purpose of this study was to compare the relative cost-effectiveness of florfenicol with that of tulathromycin for treatment of undifferentiated fever (UF) in feedlot calves at ultra-high risk of developing UF that receive metaphylactic tulathromycin on arrival at the feedlot. Calves that received therapeutic florfenicol had lower overall mortality (P=.045) and bovine respiratory disease mortality (P=.

Influence of exercise on thermographically determined surface temperatures of thoracic and pelvic limbs in horses.

Objective: To determine the amount of time required for surface temperatures of thoracic and pelvic limbs in horses to return to pre-exercise temperatures after high-speed treadmill exercise, as detected via infrared thermographic imaging.

Design: Prospective study.

Animals: 6 Thoroughbreds.

Transportation of cattle.

Until recent years, relatively little attention has been given to beef cattle transportation management and research in the United States As oulined in this article, it is clear that there are significant physiologic changes occurring in cattle as a result of transport and handling. These physiologic changes encompass, among others, effects on immune system function, disease incidence, and carcass quality. Significant advancements have been made during the past decade in the use of appropriate cattle-handling techniques, facility design,and research promoting our understanding and the attenuation of transport stress.

The effect of perineural anesthesia on infrared thermographic images of the forelimb digits of normal horses.

Infrared thermography is an imaging modality gaining popularity as a diagnostic aid in the evaluation of equine lameness. Anecdotal reports of skin hyperthermia induced by local anesthesia, detected by thermography, have been made; however, no controlled studies have been reported. The purpose of this study was to examine the effects of perineural anesthesia on infrared thermographic images of the forelimb digits in normal horses.
