91探花

Eight projects that will benefit dogs, cats, and horses recently received a total of $240,000 in funding through the Sir James Dunn Animal Welfare Centre (SJDAWC) at the Atlantic Veterinary College, 91探花. More than 100 projects have been funded by the Centre since it was established in 1994.

"We are very grateful to the Friends of the Christofor Foundation for their ongoing support of the Sir James Dunn Animal Welfare Centre," says Dr. Alice Crook, the Centre's Coordinator. "This year the Centre has funded five new research projects and renewed funding for three service projects. We are particularly excited about the new Chinook Project, through which AVC clinicians and students will provide veterinary services to a small community on Baffin Island."

This year's projects, which were determined to be eligible for funding through the Sir James Dunn Animal Welfare Centre's 2006 funding competition, will be carried out by faculty and students at the Atlantic Veterinary College at 91探花.

Originally established as the Animal Welfare Unit in 1994, the Sir James Dunn Animal Welfare Centre funds projects that benefit companion animals, horses, and wildlife. Since 1994, approximately 85 faculty, 12 graduate students, and hundreds of veterinary students from the Atlantic Veterinary College have been involved in animal welfare projects funded by the Centre.

Funded by the four Atlantic provinces, the Atlantic Veterinary College at 91探花 is committed to excellence and innovation in education, research and veterinary service. Over the past 20 years, the College has graduated approximately 1,000 doctors of veterinary medicine, has become known around the world for its research capabilities, and is the Atlantic region's only full service veterinary referral hospital.

Information is provided below on each of the eight projects funded through this year's competition:

Evaluation of platelet function in ill dogs (Dr. Shelley Burton)

Platelets are small blood cells that are important in the formation of blood clots. Dogs with various illnesses, including liver, kidney, heart or inflammatory disease, or cancer, can have changes in platelet function that can lead to serious complications or death. Existing tests of platelet function are crude in nature and somewhat uncomfortable for patients. Tests may require shipment to specialized laboratories, which is expensive and time-consuming.

The situation has improved recently in human medicine with the development of a simple machine, the Platelet Function Analyzer (PFA)-100, that assesses the function of platelets through a measurement called closure time. In a pilot project funded through the SJDAWC last year, Dr. Burton established normal AVC reference values for healthy dogs using the PFA-100. The current project will use the analyzer to assess results in ill dogs with possible increased or decreased platelet function. This knowledge will assist in diagnosis and treatment of these ill canine patients, and, once the results are published, of future patients at AVC and elsewhere.

Survival profile of Standardbred horses on PEI (Dr. Susan Dohoo)

There have been few studies looking at longevity of horses. The profile of the life span of Canadian Standardbreds, including reasons for career termination, is not known. This is a very specialized breed, and few of the horses that are unsuitable for racing or breeding move into a second career as a performance or recreational horse.

PEI has a very strong Standardbred industry, with many stables involved in breeding and racing. This study will provide a profile of a sub population of horses involved in all sectors of the industry, over a one-year period. For each horse enrolled in the study, baseline data will be collected, including age, sex, breeding and racing history, present health status and management factors. Each month, the farm owner/manager will be visited, and data collected on any changes in health status, management factors, or racing performance of the individual horses, as well as changes to the herd, including reasons for culling. The data will be analyzed to describe the life span of Standardbreds on PEI, and to identify major risk factors for early end of career. This will provide guidance for future studies to modify these risk factors, with the ultimate goal of improving the quality of life and longevity of Standardbred horses in Canada.

Health management services for the PEI Equine Retirement Society, Inc. (Dr. Wendy Duckett)

The PEI Equine Retirement Society Inc. (PEIERS) is a non-profit organization dedicated to the rehabilitation of horses destined to be destroyed or shipped for the meat industry, and to finding new homes for them as pets or pleasure horses. Since its founding in O'Leary in 1996 by Mr. Dale Cameron, the Society has taken in 27 horses, of which 14 have been placed in new homes, six have been euthanized due to intractable health problems, and seven are currently at the facility. Through the support of the Sir James Dunn Animal Welfare Centre, AVC has provided preventive medical care to the horses at the Society from the beginning.

Funding for this project has been continued for two more years. The program includes a physical exam on all horses that come to the PEIERS, a parasite monitoring and control program for the facility, dental work, routine vaccinations, and minor surgical and medical procedures as needed. The program includes vaccination against Eastern, Western, and West Nile Virus Encephalitis, and screening of all horses arriving at the facility for equine infectious anemia. AVC senior veterinary students, interns, and residents all participate in the care of these horses. This project provides significant benefits to the horses through basic preventive medicine in preparation for adoption, and by minimizing respiratory disease and parasite burden at the facility.

Health management services for Handibear Hills Equine Sanctuary, Inc. (Dr. Wendy Duckett)

Similar to the project outlined above, this project provides preventive medical care to the horses at the Handibear Hills Equine Sanctuary, Inc. For 20 years, this facility in South Granville, PEI has provided a refuge for horses needing a home. Through programs such as the Trailblazers Club, young people and adults spend time at Handibear Hills learning to ride, groom, and generally care for the horses.

Funding for this project is continued for two more years. The program provides regular dental care and vaccinations for the 21 horses currently at the sanctuary, as well as parasite monitoring and control. The program includes vaccination against Eastern, Western, and West Nile Virus Encephalitis. AVC senior veterinary students, interns and residents all participate in the care of these horses.

The Chinook Project - Providing veterinary care to Kimmirut, Nunavut (Dr. Lisa Miller)

This project will provide basic veterinary care to an isolated community on the south shore of Baffin Island. The community has a population of 450, many of whom maintain a traditional lifestyle involving hunting, fishing, and several strong sled dog teams. There is an estimated dog population of 115. No veterinary care is currently available.

A volunteer team of one co-ordinator, two clinicians, one senior veterinary student, and up to four additional vet students, will travel to Kimmirut for one week in August. Team members will provide veterinary care for sled dogs and homebound dogs in the form of vaccinations, examination and treatment for parasites, spaying and neutering, and some medical and surgical treatments (such as tumour removal). The AVC volunteers will also provide an educational program for interested community members. Adults will be given basic information about emergency care, vaccinations, and parasite prevention; and supplies will be left with them to improve the well-being of their animals. Children will receive information about animal welfare and caring for the dogs.

Chinook team members will also participate in a cultural exchange, to allow them to broaden their understanding of Canadian diversity. Participants will also keep journals during their stay, which will be compiled into a record of the experience. This inaugural project provides funding for two summers; it is anticipated that the programme may travel to other Northern Canadian communities in the future.

Development of an objective scoring system for changes to the equine pituitary gland in aged horses (pilot project) (Dr. Lisa Miller)

Equine Cushing's disease, or PPID, occurs in about 30% of horses over 20 years of age. The disease results from overproduction of hormones by the pituitary gland, with resulting impairment of immune and metabolic function. This causes an array of clinical syndromes, including laminitis (frequently resulting in euthanasia), pneumonia, muscle wasting, and diabetes. There is effective treatment available for PPID, but there are difficulties with diagnosis, due in part to inconsistencies among veterinary pathologists in interpreting histopathological changes in the pituitary gland.

This pilot project will involve three pathologists who will evaluate, individually, histopathological changes in the pituitary glands of aged horses which were euthanized for unrelated reasons. Information about the horse's age, clinical history and hormone levels will be collected before death. The pathologists will develop and verify objective criteria for grading the changes, which will eventually allow veterinarians to more accurately diagnose, and subsequently treat, PPID.

Medical and surgical care of homeless animals (Dr. Caroline Runyon)

Since first receiving funding in 1994, more than 2,750 dogs and cats have received care through this program. Funding has been granted to this project for a further two years to continue to address the problems of pet overpopulation and homeless animals in the region. Injured or ill animals brought in to the AVC Veterinary Teaching Hospital by the PEI Humane Society or Good Samaritans receive physical examinations, x-rays, and/or other diagnostic procedures, emergency medical care, and continued medical or surgical care (including neutering as required) in consultation with the shelter. Some lost animals are claimed by their owners, while most, once healthy, are placed in homes through standard shelter adoption. Some animals are placed in "special needs" adoptive homes because they require specific care during recovery. Animals with severe illness or extensive injuries are humanely euthanized.

Assessment of a new diagnostic test for inflammatory airway disease in the horse

(Dr. Maureen Wichtel)

Inflammatory airway disease (IAD) causes cough and reduced performance in horses of all ages. It affects a large proportion of stabled horses and, if left untreated, may lead to chronic lung damage, commonly known as "heaves." Equine pulmonary function testing (PFT) can lead to earlier diagnosis of airway inflammation; however such testing is not available in Maritime practices or at the AVC because of equipment costs and lack of portability.

This project will look at a new, non-invasive, portable PFT system (Open Plethand#153;) which shows promise as a practical screening test for IAD. Dr. Wichtel will compare lung function, using the Open Plethand#153; system, with lung inflammation, as assessed by bronchoalveolar lavage (BAL) cytology and other traditional diagnostic techniques. If the non-invasive, portable and affordable PFT system correlates well with the results of BAL, then it will likely become the method of choice for the diagnosis of IAD in horses. Earlier diagnosis will prevent the progression of IAD to heaves, one of the most debilitating respiratory diseases in the horse.
