College of Agriculture and Life Sciences

Dairy Science

Overview

• The purpose of the dairy science program is to offer students the opportunity to prepare themselves for a wide variety of careers by developing both their technical and interpersonal skills. Key factors in achieving this purpose are a challenging yet flexible curriculum that can be individualized to meet the educational needs and interests of each student, counseling to assist each student in designing individual programs, and extracurricular activities to enhance development of interpersonal skills.
• Students may select from three curricula: production business management; science/biotechnology/pre-veterinary; and dual major. All options provide students with the opportunity to acquire a broad education in the sciences, social sciences, economics, mathematics, and communications while learning the basic principles of dairy science.

Dairy Enterprise Management Option

• This is the most flexible curriculum, with at least 30 credits of electives. Suited to students with an interest in various fields of dairy production (herd manager, farm manager), allied agri-business industries (feed, artificial insemination, equipment), agricultural communications, public relations, extension, breed fieldperson, and a variety of other positions. Graduates in this option have also gone on to careers in college instruction, elementary school instruction, bank investment management, feed sales, and milk marketing, to name a few.

Biotechnology/Pre-Vet Option

• This option is recommended for students who plan to continue into graduate or professional school or who plan a career in quality control, laboratory work, or research and product development. It provides an excellent base in chemistry, mathematics, physics, biology and biochemistry for advanced study in many areas.

Dual Emphasis Option

• This option is recommended for students who plan to concentrate in more than one academic area as they prepare for future careers. A few of the popular minors and double majors that students may earn while completing their Dairy Science degree requirements include: Agricultural Economics, Animal and Poultry Sciences, Biology, Computer Sciences, and Crop and Soil Environmental Sciences.

Opportunities to Excel

• Dairy science students may elect to dual major or minor in animal science, agricultural economics, or any of many other departments. Students are also encouraged to actively participate in extracurricular clubs and judging teams.
• Active participation in research projects in lactation, genetics, nutrition, reproduction, and management provide qualified students valuable research experience with departmental scientists as well as part-time employment opportunities. These opportunities are available to students in all options and enhance their preparation for advanced study and provide a better understanding of the research process.
• The dairy science honors program offers outstanding students the opportunity to enrich and broaden their academic programs. Honors students work closely with individual faculty members in choosing honors classes, colloquia, independent study, and research projects. Graduation "in honors" requires successful completion of university honors requirements, a comprehensive oral examination, and an honors thesis.
• Graduate programs of study leading to the M.S. and Ph.D. also are offered (see Graduate Catalog).

Course Requirements

• All curricula for the various options contain a core of courses to assist students in developing knowledge and ability in natural sciences (biology and chemistry), computational skills (math and computer science), writing and communication (English, communications, and seminars), as well as animal physiology and production, nutrition and genetics, farm finance, food science and dairy sciences. A list of courses specified for each option may be obtained upon request from the department. In the following listing, semester hour credits are shown at the right.
