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.

Feeding Waste Milk to Calves: Reducing Antimicrobial Resistance

June 07, 2018

An undesired consequence of the use of antimicrobial drugs in cattle is the presence of drug residues and/or metabolites in feces and urine, or in the milk of lactating animals. In lactating dairy cattle, this translates into production losses due to withholding of nonsaleable waste milk containing drug residues.
