Content presented by Claire Underwood, Assistant Professor in Clinical Large Animal Diagnostic Imaging
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 POCUS. She will also discuss case examples of their use in monitoring and diagnosis.

In this webcast hosted by Dr. Alycia Chrenek, Dr. Jeff Caswell will provide an overview of Mycoplasma bovis pneumonia, arthritis, and otitis in beef and dairy calves, and individual-animal diagnosis. 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...

Bovine Coronavirus (BCoV) presents three distinct and contagious syndromes. Cattle can contract BCoV orally or by inhaling contaminated aerosols. The first form, neonatal diarrhea, affects calves during their first weeks of life. It can persist for 3 to 6 days and can be fatal. Then there's winter diarrhea, the second syndrome, which brings on watery diarrhea in adult cattle, sometimes mixed with blood. This can lead to depression, dehydration, and a temporary decrease in milk production...

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...

The prevalence, anatomical distribution, or nature of cutaneous, hair and oral mucosal abnormalities (CHMAs) in cattle is uncertain. For this reason, the authors have determined how often dairy cattle admitted to a veterinary teaching hospital (VTH) had CHMAs (except for foot and ear canal) on physical examination and if there was an age-related difference. In this descriptive, observational, prospective study, CHMAs of dairy cattle admitted to the VTH of the Université de Montréal were...

Additional efficacious immunomodulatory treatment is needed for the management of immune-mediated disease in horses. Mycophenolate mofetil (MMF) is an immunosuppressive drug that warrants assessment as a viable therapeutic agent for horses. The objective of this study was to evaluate the pharmacokinetics (PK) of multiple-day oral dosing of MMF in healthy horses and to determine the tolerability of this dosing regimen. Six healthy Standardbred mares received MMF 10 mg/kg PO q12h for 7 days in...

Horses with severe equine asthma had higher concentrations of MMP-9 in the BALF. This study determined Tregs and inflammatory cytokines in BALF and peripheral blood (PB) of adult horses with mild and severe asthma and different BALF cytological inflammation profiles. Horses of diverse breeds with asthma (age range: 2-20 years, n = 24) were divided into groups according to the number of points obtained in a standardized clinical scoring system (mild-moderate equine asthma - MEA, severe equine...
