Large Animal Ultrasound Fellowship

Notice to potential candidates:  We would like to inform interested veterinarians that we will not be offering the fellowship program for the 2019-2020 academic year, as we are retaining our current fellow for a second year.  We plan to open recruitment for the 2020-2021 fellowship position in the Fall of 2019.  Please check back at that time for important application information and deadlines.  Deadlines will be similar to those listed in previous years and visitation will be limited to the recruitment period.  The opening of our recruitment period will be announced on our facebook page.  (

The goals of the Large Animal Ultrasound Fellowship are to produce veterinarians with advanced technical and interpretative skills in this important clinical discipline. The species emphasis is equine, but fellows will gain exposure to other large animal species such as cows, goats, sheep and pigs. This position is an 80% clinical appointment with 20% time for off clinic pursuits (see below). Annual salary is $31,407 with medical benefits included. Housing is not provided. The fellowship is generally one year in length, and runs from August 1-July 31.

This webpage is designed to provide potential applicants with detailed information regarding the program, including overall service information and what to expect from the fellowship. Graduates of the program have gone on to secure faculty positions in large animal ultrasound, residencies in radiology and equine surgery and established regional ultrasound consulting services.

About the UC Davis Large Animal Ultrasound Service

The Large Animal Ultrasound Service provides diagnostic imaging services five days per week. The majority of the service caseload is supported by the hospital’s Equine Surgery and Lameness Service, therefore, a large percentage of ultrasound examinations are musculoskeletal in nature. However, a wide variety of ultrasound exams are performed. The candidate selected will receive training in the sonographic evaluation of all areas, including the abdomen, thorax, cardiac, and ophthalmologic exams. The equine caseload consists of a variety of performance horses, including dressage, hunter/jumpers, race, endurance horses, western performance horses (cutting, reining, roping, barrel racing), pleasure horses and specialty breeds such as Peruvian Pasos. A working knowledge of performance horses is beneficial. There is little to no emergency duty. Emergency colic ultrasound evaluations are performed by the surgery resident on call. The Equine Medicine Service and Livestock Medicine and Surgery Service perform medical emergency ultrasound evaluations.

Our Equipment

The Large Animal Ultrasound Service has a full range of equipment available for all aspects of equine, livestock and small ruminant ultrasound. Our state-of-the-art ultrasound machines are carefully selected for their superior imaging abilities. We are fortunate to have two excellent ultrasound console systems that allow us to evaluate two patients simultaneously. Both machines excel at musculoskeletal and abdominal imaging. We also have a grab-n-go portable system that facilitates quick responses to stall-side emergencies, intra-operative and other procedures. Transducers available include 6-18 MHz and 5-10 MHz linear transducers for musculoskeletal use, 4-8 MHz microconvex transducers for neonatal and small ruminant abdominal/thoracic imaging, 2-5 MHz curvilinear transducers for adult equine abdominal and thoracic imaging and a 2-5 MHz phased array transducer for cardiac imaging.
