Addendum to Course Description
This course is designed to introduce the student to the wide range of infectious and non-infectious diseases and disorders of large animal species. The student will develop knowledge of the scientific name; the common name(s); the species affected; the age, sex, and breed predisposition; the etiology/pathogenesis; the clinical signs; the diagnostic tests and the basis for the diagnosis; the treatment; and the prevention for each disease presented. Large animal diagnostic and treatment procedures will be covered in the laboratory portion of the course.
It is designed for second year veterinary technology students and is a graduation requirement for the Associates Degree in Applied Sciences in Veterinary Technology. Credits in this course are not transferable to a four year school towards a baccalaureate degree.
There is no specific text required for this course, although The Merck Veterinary Manual is recommended as a reference book.
Intended Outcomes for the course
Upon successful completion of the course, the student should be able to:
- Recognize the important clinical diseases affecting sheep, goats, cattle, camelids, horses and swine- including disease etiology, pathogenesis, clinical signs, treatment, and prevention.
- Recognize the common zoonotic diseases of the species listed above.
- Understand and assist with commonly used diagnostic and treatment procedures used in large animal veterinary practice.
- Recognize and assist with the elements of a thorough physical examination of camelids and horses.
- Correctly and safely position horses for radiographs using portable radiographic equipment to evaluate the equine distal limb.
- Understand and assist with the techniques used for hoof and dental care in camelids and horses.
- Recognize the anesthetic drugs commonly used for sedation and anesthesia in the horse and special clinical considerations of anesthesia of the horse.
Course Activities and Design
This is a three credit-hour course that meets for two lecture-hours per week, and three lab-hours per week. This course is presented as a series of lectures and laboratories; diseases and disease processes will be covered in order based on species and organ systems. In areas where one disease occurs in multiple species, the comparative aspects shall be presented to the student. The laboratory will concentrate on commonly used diagnostic and treatment procedures used in large animal veterinary practice.
Outcome Assessment Strategies
Grading will be based upon student understanding of the course content as demonstrated by periodic examinations, homework assignments, quizzes, a comprehensive final exam, performance of laboratory tasks, and attendance. To be eligible for a passing grade, the student must have attended a minimum of 80 percent of each of the lecture and lab classes.
Course Content (Themes, Concepts, Issues and Skills)
Content labeled with an asterisk indicates content required by our accreditor. Content that is also italisized indicates tasks that the student must be able to perform since they are listed as “essential tasks” by the Accreditation Policies and Procedures of the American Veterinary Medical Association's Committee on Veterinary Technician Education and Activities.
