Undergraduate Program


Animal Science

The undergraduate program in animal science is designed to prepare students for a variety of careers by providing a strong basic science foundation paired with practical animal experience gained through the multiple farm facilities near campus.  Graduates may be employed in research, extension, agribusiness, finance, marketing, public relations, event or association management, farm ownership, and more.  Graduates often attend veterinary or graduate school as well.

All animal science students must complete a set of required core courses that include anatomy and physiology, nutrition, genetics, and management. These courses are taught using beef cattle, companion animals, dairy cattle, horses, poultry, and swine.  Additional courses are then added to allow students to personalize their program of study.  Scientific principles of biology and animal science are key components of the program although the animal science major also provides enough flexibility for students to choose a path that meets their needs and interest areas.  Students choose from one of the following concentrations as they plan their degree program: animal industry, companion and exotic animal biology, dairy industry, or animal biology/preveterinary.

The animal industry concentration is designed to prepare students for careers in managing animal operations. Marketing, sales, and production of animals and animal products offer numerous employment opportunities. The companion and exotic animal biology concentration prepares students for careers in the areas of small animal nutrition, pet food sales, and captive and small animal management. Students may also use their elective credits to complete the preveterinary requirements and apply to MSU’s College of Veterinary Medicine. The dairy industry concentration is designed to prepare students for careers in the dairy industry. Potential career opportunities include operating and managing dairy operations and working for dairy allied businesses in the areas of nutrition, reproduction, health, finance, and marketing. The animal biology/preveterinary concentration is designed for students who are interested in an advanced degree in animal science or a career in veterinary medicine. The requirements for admission to MSU’s College of Veterinary Medicine are included in the requirements for this concentration. Using electives, students may be able to complete requirements for other veterinary schools. Each veterinary school requires different courses for admission. It is the student’s responsibility to assess requirements and transferability of courses to the desired veterinary school.

Students who are enrolled in the Bachelor of Science degree program with a major in animal science may elect a Minor in Plant, Animal and Microbial Biotechnology.  For additional information, refer to the Minor in Plant, Animal and Microbial Biotechnology statement.

Requirements for the Bachelor of Science Degree in Animal Science

  1. The University requirements for bachelor's degrees as described in the Undergraduate Education section of this catalog; 120 credits, including general elective credits, are required for the Bachelor of Science degree in Animal Science.

    The University's Tier II writing requirement for the Animal Science major is met by completing one of the following courses:  Animal Science 301, 313, 314, 409, or 435. Those courses are referenced in item 3. a. below.

    Students who are enrolled in the Animal Science major leading to the Bachelor of Science degree in the Department of Animal Science may complete an alternative track to Integrative Studies in Biological and Physical Sciences that consists of the following courses:  Biological Science 161 and 171, Chemistry 141, and Chemistry 143 or 251. The completion of Biological Science 171 satisfies the laboratory requirement.
