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...

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%...

Minerals play vital roles in physiologic processes. Calcium, phosphorus and magnesium are common minerals. Secretion, absorption and homeostasis of these minerals are affected by associations between the active vitamin D and parathyroid hormone (PTH). The aim of this study was to assess concentrations of vitamin D, PTH and minerals, such as calcium, phosphorus and magnesium in horse sera, as well as associations of these values with lameness in horses. In the references, the reasons for...

Rebound gastric hyperacidity (RGH) secondary to hypergastrinemia has been suggested to contribute to the rapid recurrence of equine squamous gastric disease (ESGD) in horses after discontinuation of omeprazole. The objective of this study was to evaluate changes in serum gastrin and chromogranin A (CgA) concentrations in response to medium-term (57-day) omeprazole treatment and after omeprazole discontinuation. Horses received 2.28 g of oral omeprazole PO q24h for 57 days within a 61-day...

Blackleg is a common cause of death in cattle, mostly caused by the bacterium Clostridium chauvoei. Cardiac lesions were traditionally considered uncommon in cases of blackleg in cattle until a 2018 study reported otherwise. In this study, researchers aimed to determine the prevalence of cardiac disease among cattle that died of blackleg in Tennessee. The outcome of this study could reinforce the importance of assessing cardiac lesions in suspected cases of blackleg in cattle. The University...
