Professor | Animal Science

Specialization: Animal Scientist: Reproductive Physiology/Embryology

Overview

As a reproductive physiologist, reproductive failure of cattle after a single insemination (35 to 40% in beef and 50 to 70+% in dairy is problematic on a global scale. Although basis for failure is multi-factorial, my laboratory has focused on identifying mechanisms through which elevated body temperature in estrus active females affects pregnancy outcomes in both a positive and negative manner. Success in doing is important to maintain a global supply of nutrient dense meat and dairy products.

This is a core course for animal science majors and an elective for biochemistry, cellular and molecular biology majors. Course materials may also be of interest to students majoring in other majors in agriculture, biological and life sciences. (Same as BCMB 320.)

Contact Hour Distribution: 2 hours and 1 lab.
(RE) Prerequisite(s) : Grade of C– or better in ANSC 220, BCMB 230, or BCMB 440; or consent of instructor.
Recommended Background: Introductory animal or human physiology course.
Registration Restriction(s): Minimum student level – junior.

Semesters Offered: Fall
ANSC 420 - Advanced Reproductive Techniques
3 credit hour(s)

Collection, evaluation, and preservation of ova, spermatozoa and embryos; application of methods of natural breeding and techniques of artificial insemination and embryo transfer; herd sire and dam evaluation; pregnancy determination; gestation and parturition; infertility; recent advances in theriogenology. Students completing the course with a grade of C or higher may qualify for certification in artificial insemination.

Contact Hour Distribution: 1 hour and 2 labs.
(RE) Prerequisite(s) : ANSC 320 with a grade of C or higher.
Registration Restriction(s): Minimum student level – senior.
