Portland Community College | Portland, Oregon

In this course the student will begin to develop the skills necessary to function safely as a veterinary technician around the various types of livestock species.

This is designed for first 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.

The required text for this course is Modern Livestock and Poultry Production by Gillespie.

This course is designed to be a lecture and laboratory course. It is a four-credit-hour course that meets for three-lecture hours per week and three-lab hours per week.

Topics covered will be classification of livestock, digestive systems and basic nutrition, beef cattle, llamas and alpacas, sheep, swine, dairy cattle, goats, horses, rabbits, poultry, genetics and reproduction, and animal rights.

• Grades will be based on the student ’s understanding of the course content as demonstrated by periodic lecture examinations, laboratory exercises, a comprehensive final exam, and by attendance. Also in order to receive a passing grade, the student must have attended a minimum of 80 percent of each of the lecture and laboratory classes.

• Upon successful completion of the course, the short term outcome will be that the student will have satisfactorily accomplished the goals and objectives of this course content guide and confirmed as provided in the assessment above. The desired long-term outcome is for the student to gain sufficient skills and knowledge of animal science to successfully pass the National Veterinary Technician Board Examination and effectively utilize the knowledge gained in their Cooperative Education Experience and as a practicing veterinary technician upon graduation. The course content guides are developed by college-wide subject area faculty and approved by the administration.

  Laboratory tasks with an asterisk indicate tasks the student must be able to perform since they are considered to be “essential tasks,” and tasks marked with two asterisks indicate tasks considered to be “recommended tasks” by the Accreditation Policies and Procedures of the Committee on Veterinary Technician Education and Activities of the American Veterinary Medical Association. Tasks with no asterisks are considered neither “essential” nor “recommended”, but are taught based on instructor, SACC, and/or advisory committee recommendations. This course content guide specifies which tasks students are required to perform (as indicated in the task description) and the tasks on which they have been educated and have observed but individual performance is not required.
