Oral Magnesium and Boron Found to Reduce Headshaking in Horses

April 23, 2019
Giving magnesium and boron can benefit headshaking horses, the findings of research suggest. Trigeminal‐mediated headshaking, which used to be called idiopathic headshaking, is caused by a low threshold of firing of the trigeminal nerve in the face. In most cases, the condition is worse during spring and summer, and geldings are over-represented. Various treatments have been tried, including face masks with ultraviolet light protection, nose nets, nutritional supplements, antihistamines, corticosteroids, neuromodulation, and even surgery on the nerve. Results have been variable.

Cow’s Near Fatal Ingestion Prompts Surgery

March 01, 2019
Tag 1839, a 2-year-old Jersey dairy cow, was brought to the UC Davis veterinary hospital for suspected pneumonia. She had been treated appropriately by her primary veterinarian, but without significant improvement, so she was referred to the Livestock Medicine and Surgery Service for further diagnostics and treatment. A blood test showed evidence of severe chronic inflammation, and an ultrasound showed that she had fluid, inflammation, and an abscess in her chest cavity. Radiographs of her chest showed that she had a foreign body—a piece of wire—extending from the first compartment of her stomach toward her heart.

UC Davis Vet School Diagnostic Lab Performs Critical Disease Testing for Equine Herpesvirus

October 10, 2018
Equine herpesvirus-1 (EHV-1) is relatively widespread in horses; approximately 60 percent of healthy horses harbor the virus. While the more common form of EHV-1 can cause respiratory illness as well as abortion, it is rarely fatal. However, a neurological strain of this virus, also known as equine herpes myeloencephalopathy (EHM), can kill 30 to 50 percent of affected horses. That's why it is critical for the California Animal Health & Food Safety Laboratory to be able to use PCR testing to differentiate between strains.
