Students are expected to have completed the equivalent of a B.S. degree (for application for the M.S. degree) or M.S. degree (for application for the Ph.D. degree) in Animal Science, Range Science, or a closely related area.  In selecting applicants, the Animal & Range Sciences Graduate Committee will consider the prospective student’s statement of purpose, undergraduate and graduate achievement (university transcripts), GRE scores, and letters of recommendation (3 required).  Generally, a minimum GPA of 3.0/4.0, and GRE scores of 150 verbal and 146 quantitative (450 verbal and 550 quantitative in previous GRE scoring system) are required for full admission.  GRE scores cannot be over 5 years old at time of application.


NOTE: There must be a faculty member available to advise a student with funding and
a project before a new graduate student will be accepted.

  • Students in the Animal Science or Biological Science Emphasis areas must meet the Proficiency Requirements below.

Proficiency Requirements

By the time a student completes a M.S. in Animal & Range Sciences, they must have successfully completed undergraduate or graduate coursework in the content areas given below depending on their degree emphasis.  Examples of MSU courses that fulfill these requirements are given.  Students who have successfully completed an equivalent course may apply that course toward the proficiency requirements, subject to the approval of the student’s Graduate Committee.  

A. Proficiency Requirements for Animal Science Emphasis (must complete 3 of the 4 areas)

  • Breeding/Genetics  (ANSC 322 – Principles of Animal Breeding & Genetics, or BIOB 375 – General Genetics)
  • Physiology/Reproduction  (ANSC 321 – Physiology of Animal Reproduction)
  • Nutrition  (ANSC 320 – Animal Nutrition)
  • Production/Management  (ANSC 434R – Beef Cattle Management)

B. Proficiency Requirements for Biological Science Emphasis (must complete 15 credits from the areas listed, at least 9 credits upper division)

  1. Biology  (BIOB 256, 258, 260 – Introductory Biology)
  2. Ecology  (BIOE 370 – General Ecology, BIOE 405 – Behavioral & Evolutionary Ecology)
  3. Chemistry  (CHMY 141, 143 – College Chemistry I & II, CHMY 211 – Elements of Organic Chemistry, CHMY 311 – Fundamental Analytical Chemistry, CHMY 321, 323 – Organic Chemistry I & II)
  4. Biochemistry  (BCH 380 – Biochemistry)
  5. Entomology  (BIOO 262IN – Intro to Entomology)
  6. Food Science/Meat Science  (Introductory Food Science or upper division food science or food safety course)

Minimum Requirements for Ph.D. in Animal & Range Sciences

The Ph.D. program is based upon an area of specialization in research and intensive coursework that would normally require three years of full-time work beyond the M.S. degree.  In addition to departmental requirements candidates must fulfill the requirements of The Graduate School.  The general departmental requirements include:

  • In addition to requirements set forth by The Graduate School, Ph.D. students must complete the following:
    • 3 credits of ARNR 507 (within the Ph.D. period).
    • A graduate (400– or 500–level) course in experimental design and 2 graduate statistical methods courses must be completed within the Master’ s and Ph.D. program.
  • The major professor and the student’s graduate committee will determine additional specific course requirements for completion of the Ph.D. degree.
  • Students must choose either the Animal Science emphasis or the Range Science emphasis.
