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...

Little is known about thyroid diseases in ruminants, probably due to the lack of diagnosis techniques developed in this species. However, thyroid ultrasound (TU) is widely used in human and in companion animal's medicine. It is a cheap and non-invasive examination, which allows for the identification of thyroid structures or diffuse diseases.
The aim of this study was to evaluate the accuracy of TU in five calves and five cows through inter- and intra-observer repeatability.
The size of the...

Administration of supplemental oxygen may be necessary for horses experiencing significant hypoxemia (PaO2 <80 mm Hg) associated with respiratory disease. Providing effective oxygen supplementation to the standing adult horse can be challenging, with described methods for delivery including oxygen mask, intratracheal catheterization, and nasal cannula.
This study evaluated the effects of various flow rates and fractions of oxygen on arterial blood gas parameters and on the fraction of...

In the present review, the authors, based on the multiple functions performed by the liver, analyze the multiple biochemical and hematological changes as an expression of altered liver function in the horse.
The liver performs important metabolic functions related to the synthesis, degradation, and excretion of various substances. Modification of these functions can be evaluated and diagnosed by determining serum concentrations of several serum analytes, including enzymes and other endogenous...

Pheochromocytomas have been previously reported in horses, but successful antemortem diagnosis and surgical removal without recurrence of clinical signs has not been described. The aim of this study was to report the clinical presentation, diagnostic evaluation, surgical technique, anesthetic management, and post-operative care of a mare diagnosed with pheochromocytoma.
This clinical case report describes an 18-year-old Quarter Horse mare presented for recurrent episodes of colic, profuse...
