Applicants are expected to have completed the equivalent of a B.S. (or M.S.) degree in Animal Science, Range Science, or a closely related area prior to application.  In selecting applicants, the Animal & Range Sciences Graduate Committee will consider 1) the prospective student’s statement of purpose that includes the name of the faculty with whom you have been in contact, 2) undergraduate and graduate transcripts (GPA expectation >3.0/4.0), 3) three letters of recommendation, including one from the potential advisor, and 4) GRE scores (GRE expectation > 300 combined). GRE scores are valid for a period of 5 years for all students seeking admission to the Department’s M.S. program.  Students applying for the Ph.D. program are required to transmit current GRE scores unless transcripts indicate an earned research thesis-based M.S. degree in animal and range sciences or a related field in order to be considered for admission to the Department.  However, current GRE scores may be required by certain faculty advisors prior to admission to a graduate program.


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.
Prospective students are strongly advised to contact potential advisors in advance of applying.

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.
  • Animal and Range Sciences Ph.D. students must complete the following:
    • One credit of ARNR 507 Research Methods
    • Two credits of ARNR 594 Seminar
    • A three credit graduate (400-500 level) course in experimental design and six credits of graduate statistical methods courses within the M.S. and Ph.D. program
  • D. students in the Ecology and Environmental Sciences within the Animal and Range Sciences department must complete the following:
    • One credit of ARNR 507 Research Methods
      • One credit of ARNR 594 Animal and Range Sciences Seminar
