Animal Sciences Undergraduate Major (BS, HBS)
This program is available at the following location:
- Corvallis
Options available:
The Animal Sciences major provides up-to-date information on methods of rearing livestock and poultry, that produce meat, milk, eggs, wool, and other animal products. In addition, it addresses the care of animals that enhance human well-being through companionship, recreation, and human aid such as horses and companion animals. Essential to this is knowledge generated from the fields of animal behavior/bioethics, genetics, nutrition, and physiology. The program explores modern areas of animal biotechnology and data processing and how they apply to present day livestock and poultry production.
Increasing demands for livestock and poultry products by a rapidly expanding human population mean potential employment for well-trained individuals in such areas as farm, ranch, feedlot operation; meat, poultry, egg and milk processing, meat grading with the USDA; Federal Cooperative Extension Service, county and 4-H work; sales or technical employment with commercial feed, seed, and chemical companies and pharmaceutical houses; agricultural loan officer; government agency positions at local, state and federal levels; the Peace Corps; animal welfare auditing; as well as in journalism, mass media, and public policy. The expanding support structure for companion animals has created a growing job market for graduates in areas such as animal behavior consultant; veterinary technician (animal nurse); and business management. In addition, students become prepared to go on to advanced studies in animal sciences, veterinary medicine, and education.
Major Code: 125
Upon successful completion of the program, students will meet the following learning outcomes:
- Communicate discipline-specific scientific information in written and spoken formats using citation.
- Identify anatomy and physiology of organ systems and describe hormonal function in the male and female reproductive tracts of mammals and poultry.
- Classify and compare anatomy, physiology and nutritional status of commonly-raised domesticated animal species.
- Identify interactions of genotype and environment which produce phenotypes adapted to human uses.
- Apply the methods used to evaluate animal health and well-being.
The Animal Sciences major and options have no double-counting restrictions.
