Ph. D. Min Requirements
The Ph.D. program is based upon an area of specialization in research and intensive course work that would normally require three years of full-time work beyond the MS degree. Candidates must fulfill the requirements of the College of Graduate Studies.
- A minimum of 50 semester credits of course work beyond the BS degree.
- A minimum of 18 credits of ARNR 690.
- The 50 credits of course work must include:
- 3 credits of ARNR 507.
- A graduate (400- or 500-level) course in experimental design and 2 graduate statistical methods courses.
- A minimum of 30 credits must be taken through the regular registration process, on the campus of MSU after admission to the Ph.D. program
- Students must attend a seminar each semester in residence.
- The major professor and the student’ s graduate committee will determine additional specific course requirements for completion of the Ph.D. degree.
- Students must be registered for a minimum of 3 credits during a term that an examination is taken. Registration through Extended Studies does not fulfill this requirement.
- A maximum of 6 credits of Individual Problems (570) courses may be included.
- A maximum of 9 credits on a pass/fail basis (excluding 690) may be included. Individual Problems (570) courses may not be taken as pass/fail.
- Correspondence courses will not be accepted.
- Age of courses at time of graduation may not exceed 10 years. The maximum time between the comprehensive examination and granting the degree is 5 years.
- Students must choose either the Animal Science option or the Range Science option.
- By the completion of the Ph.D. students will have completed the following or equivalent
(courses completed for the MS degree may be applied):
- Animal Science Option. Students must complete 3 of the following Animal Science courses, 1 of the graduate
Range Science courses, plus 2 additional semesters of graduate (400- or 500-level)
ARNR 520 – Nutrient Metabolism of Domestic Animals
ARNR 521 – Advanced Ruminant Nutrition
ARNR 523 – Advanced Physiology of Reproduction
ARNR 524 – Advanced Animal Breeding
ARNR 525 – Muscle and Growth Biology
- Range Science Option. Students must complete 3 of the following Range Science courses, 1 of the graduate
Animal Science courses, plus 2 additional semesters of graduate (400- or 500-level)
ARNR 541 – Range Ecophysiology
ARNR 543 – Riparian Processes and Function
ARNR 544 – Advanced Grazing Management and Ecology
ARNR 553 – Grazing Behavior of Livestock and Wildlife
- Animal Science Option. Students must complete 3 of the following Animal Science courses, 1 of the graduate Range Science courses, plus 2 additional semesters of graduate (400- or 500-level) Biological Sciences:
Students are expected to have completed the equivalent of a Master of Science degree
in Animal Science, Range Science or a closely related area. In selecting applicants,
the Animal and 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). Applicants judged to have deficiencies
in preparation could be admitted provisionally and required to enroll in additional
courses to make up the deficiencies. Generally, a minimum GPA of 3.0/4.0 and minimum
GRE scores of 450 verbal and 1000 combined verbal and quantitative are required for
International students whose native language is not English must submit scores from the Test of English as a Foreign Language (TOEFL) before admission and/or award of an assistantship. These scores must meet the minimum standards required by the College of Graduate Studies at Montana State University.
