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 their technical and interpersonal skills. We offer 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: Dairy Enterprise Management; Biotechnology/Pre-veterinary; and Dual Emphasis. 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 enterprise management.

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, genetics, 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 veterinary college or other graduate or professional schools, 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 is the most popular option and is recommended for students who plan to concentrate in more than one academic area as they prepare for future careers. Common minors and double majors that students may earn while completing their Dairy Science degree requirements include Agricultural Economics, Animal and Poultry Sciences, Biology, Crop and Soil Environmental Sciences, Spanish, Communications, Professional Writing, etc.

Opportunities to Excel

    Nearly all Dairy Science students complete a second major or minor in Animal and Poultry Science, Agricultural Economics, Horticulture, Spanish, Business Communications, Food Science and Technology, or any of many other departments. Students are also encouraged to actively participate in extracurricular clubs, judging teams and the dairy management team. Ninety five percent of students complete at least on internship prior to graduation and nearly half complete undergraduate research, an independent study, or serve as a teaching assistant.

    Active participation in research projects in lactation, genetics, nutrition, nutrient management, 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

    The graduation requirements in effect at the time of graduation apply. When choosing the degree requirements information, always choose the year of your expected date of graduation. Requirements for graduation are referred to via university publications as “Checksheets”. The number of credit hours required for degree completion varies among curricula. Students must satisfactorily complete all requirements and university obligations for degree completion.

    The university reserves the right to modify requirements in a degree program. However, the university will not alter degree requirements less than two years from the expected graduation year unless there is a transition plan for students already in the degree program.

    Please visit the University Registrar website at http://www.registrar.vt.edu/graduation/checksheets/index.html for degree requirements.

Requirements for Minor in Dairy Science

    Requirements include DASC 2474 (2 cr.), DASC 3474 (3 cr.), DASC 4374 (3 cr.), and twelve additional credits in DASC elective.

Satisfactory Progress

    University policy requires that students who are making satisfactory progress toward a degree meet minimum criteria toward the General Education (Curriculum for Liberal Education) (see "Academics") and toward the degree in Economics.

    Satisfactory progress requirements toward the B.S. in Dairy Science can be found on the major checksheet by visiting the University Registrar website at http://www.registrar.vt.edu/graduation/checksheets/index.html.
