Combined Veterinary Residency in Animal Welfare and Master of Science (MS) in Animal Welfare and Behavior

Download the PDF...

The residency in Animal Welfare is a three-year program aimed at developing a knowledge base in animal welfare in a broad variety of species under varied conditions. The training is designed specifically to fulfill the requirements for Board qualification set forth by the American College of Animal Welfare (ACAW), which may be reviewed at the ACAW website.

The Animal Welfare residency program at the University of Pennsylvania will provide the resident with welfare experience and coursework in a broad variety of species. In the first year of the training program, the resident will participate in the Certificate in Animal Welfare and Behavior, a foundational learning experience designed to generate a broad base of knowledge in animal welfare and human-animal interactions across a range of species.

In the second year of the program, the resident will be expected to participate in the Master’s coursework in a specific track designed to meet the requirements for credentialing for the ACAW. At the satisfactory fulfillment of the coursework and a capstone project, the resident will receive a Master’s degree in Animal Welfare and Behavior.

The resident will be expected to execute a field-based research project assessing risk factors for lameness in finishing pigs. This project will meet the requirements set forth for the Master’s degree capstone project and is anticipated to generate data for publications that will meet the requirements designated by ACAW. Risk factors for lameness in growing swine are poorly understood. Studies have documented marked variation in levels of lameness, and a tentative association between Mycoplasma hyosynoviae and lameness has been suggested. There is need to explore other risk factors, including those that are related to the sow farm, the grow-finish farm, antimicrobial use, nutritional factors, and the presence of M. hyosynoviae on the farm.

Residents in Animal Welfare at Penn Vet will have access to a variety of centers in which to gain experience, including the Penn Vet Working Dog Center, Penn Vet Behavior Service, Marshak Dairy, New Bolton Center Swine Teaching and Research Center, and the Semi-feral pony herd. Ongoing off-campus experiences will be set up for each resident based on interests.

Guidance in grantsmanship, leadership development, and educator training will also be provided. All residents will be reviewed annually by their residency mentor, with continuation based upon satisfactory progress.

The Department of Clinical Studies - New Bolton Center, University of Pennsylvania School of Veterinary Medicine is offering a 2-year residency in large animal theriogenology. This clinical training program is in the Section of Reproduction and Behavior. Currently, the Section consists of twelve members (faculty and professional staff), and the resident has the opportunity to train under the direction of seven Diplomates of the American College of Theriogenologists (ACT) and one Honorary Member of the ACT who is also a Board-Certified Applied Animal Behaviorist.

This program emphasizes a balance of patient reproductive health care, clinical teaching, and research. The caseload is predominantly equine; however, the residency also involves clinical work with cattle, small ruminants, camelids, and swine. Along with an active in-patient and out-patient clinic, the Center houses a reference andrology laboratory, equine assisted reproduction laboratory, and endometrial biopsy service. Our caseload provides an excellent opportunity to become proficient in breeding soundness evaluation of male and female animals; semen collection and analysis; alternative techniques for semen collection; transported semen; semen freezing; pregnancy diagnosis; reproductive ultrasonography; and assisted reproductive technologies such as oocyte recovery and embryo recovery and transfer in a variety of large animal species. Our group is also active in stallion and mare behavior evaluation and therapy. In addition to their clinical and teaching responsibilities, the resident will be expected to participate in and perform transvaginal oocyte aspiration procedures with our on-site Equine Assisted Reproduction Laboratory and will have the opportunity to work with the laboratory, which performs intracytoplasmic sperm injection, in vitro embryo culture, embryo biopsy and other advanced procedures. The resident will work closely with the high-risk pregnancy program in New Bolton Center’s Hospital for Large Animals and will be an integral member of the team that provides management and care for the reproductive component of medical and surgical cases at the hospital. The position requires after-hours and emergency on-call duty under the guidance of a boarded specialist.

Along with responsibilities for instruction of students on clinical service rotations, the resident contributes to the professional teaching program through lectures and laboratories pertaining to horses, cattle, small ruminants, camelids and swine. To gain research experience, with faculty guidance, the resident is encouraged to participate in a research project of their choice. Support is provided to publish a peer-reviewed article to meet the requirements for certification as a Diplomate of the ACT.

This program fulfills the supervised training requirements for candidacy in the ACT. This is a two-year program with a starting date of July 1, 2022. The starting annual salary is $35,568 and includes a generous benefits package. Qualifying applicants must have a VMD/DVM or equivalent degree, with a demonstrated interest in Theriogenology. A one-year internship or at least one year of general practice or equivalent experience is a prerequisite. The application should include a letter of intent indicating the reasons for seeking admission to this program and professional career goals, current resume, transcript of university performance, and three letters of reference.
