Join us on December 13 at 7 p.m. (EST) as we discuss harnessing the power of POCUS for your practice. Point of care ultrasound (POCUS) techniques represent a fast straightforward means to monitor and diagnose equine patients. Inexpensive pocket ultrasound devices are increasingly being used as ‘an extension of the stethoscope’ to answer focused clinical questions. During this webcast, Dr. Claire Underwood will cover some of the devices available along with techniques for equine abdominal...

While he briefly touches on some details about the bacterium and its interaction with the calf's immune response, his presentation focuses on the different diseases caused by M. bovis. He discusses their clinical and pathologic appearance, as well as various approaches to individual-animal...

In lieu of contracted native beef cattle feeder supply and unwillingness of packers to harvest native Holstein steers, beef x dairy cross steers and heifers represent an important class of cattle on feed. As beef x dairy cattle make up an increasing proportion of cattle on feed research into performance, carcass attributes and expected health outcomes represent important areas of discovery. This presentation will aim to summarize the current cattle feeding landscape in North America, the...

Although thoracic auscultation (AUSC) in calves is quick and easy to perform, the definition of lung sounds is highly variable and leads to poor to moderate accuracy in diagnosing bronchopneumonia (BP). The aim of the study was to evaluate the diagnostic accuracy of an AUSC scoring system based on a standard lung sound nomenclature at different cut-off values, accounting for the absence of a gold standard test for BP diagnosis. The authors considered the following pathological lung sounds:...

IntroductionPoultry is a flourishing industry all over the world including in China. To improve economic efficiency, intensive farming is increasingly popular in the poultry industry. This farming model exposes the chickens to constant stressors, such as high humidity and temperature, noise and continuous illumination, which seriously decreased weight loss, increased feed conversion rate and induced peripheral fat deposition. Chronic stress can increase the secretion of glucocorticoid (GC), a...

The aim of this retrospective study was to describe the clinical, laboratory, and ultrasonographic findings; treatment; and outcome of cattle with mesenteric torsion (MT). Medical records were retrospectively reviewed. Results were compared for cattle that survived versus did not survive to hospital discharge. Overall, 61 cattle with MT between November 1, 1986, and December 31, 2019 were enrolled. All cattle had abnormal demeanor. The most common clinical signs were tachycardia (80.3%...

Reproductive performance is an important factor in the profitability of milk production. The first three months of pregnancy are a critical period for dairy cows. This period can be divided into four segments. In the initial week following insemination, high-yielding dairy cows face a 20 to 50% risk of experiencing pregnancy loss. During the second period, spanning from days 7 to 28, the risk of experiencing pregnancy loss is approximately 30%. Moving into the third period, which encompasses...
