Teaching Experience


Current teaching responsibilities are associated with Physiology of Domestic Animals (AS254), Advanced Dairy Production (AnSc 315) and Gonadal Function (AnSc 434). I teach the reproductive biology and endocrinology portion of AS254 (approximately 30% of the 5 hr. course) which is taught every fall semester. AnSc 315 is taught every fall semester and is designed for junior, senior and beginning graduate students. The course is team-taught (my lectures cover 1/3 of the course), is writing intensive”, and I am co-coordinator. AnSc 434 is designed for advanced M.S. students and Ph.D. students and covers ovarian and testicular function.

I have been involved in the development of three new courses. Advanced Reproductive Physiology of Domestic Animals (originally AnSc 434) and Gonadal Function (currently AnSc 434) were developed to meet the needs of graduate students in our reproductive biology program. The third course, Experimental Surgery (AnSc 400) was developed to meet the need of training graduate students, postdoctoral fellows and technical staff to do experimental surgery necessary to accomplish their research objectives.

Extension Experience


Extension duties were conducted from 1971 to 1988. A reproductive herd health management program was developed, UMC guide sheets were written, and training sessions for Area Dairy Specialists were provided. In addition, there was participation in local, regional and state dairy meetings on reproductive management as well as individual consultation with dairymen. Three of my former graduate students now are regional specialists in Missouri extension.

Research Activities


The focus of this program is elucidation of mechanisms controlling ovarian function in domestic farm species. Occurrence of a fertile estrus and establishment of pregnancy early in the postpartum period are essential events for successful livestock enterprises. These events are dependent upon preovulatory follicular development, ovulation and a functional corpus luteum capable of secreting adequate amounts of progesterone to allow establishment of pregnancy. Following parturition, ovarian follicular growth and normal luteal function are often delayed which result in extended calving intervals. In beef and dairy cows, cellular and endocrine mechanisms associated with follicular growth and formations of a normal corpus luteum are unclear. Thus, mechanisms associated with both normal and abnormal follicular growth and luteal function have been and are being investigated.

One current area of focus is elucidation of endocrine, cellular and molecular factors associated with initiation of ovarian follicular growth, recruitment of follicules for continued growth, and selection of one of the cohort of follicles for dominance over the other follicles and ultimately, ovulation. Efforts are currently focused upon changes in gene expression associated with different stages of growth, development and atresia. This has been accomplished by development of cRNA probes. The molecular probes are used in situ hybridization and quantitated by image analysis to measure differences in mRNA expression for the gonadotropin receptors and steroidogenic enzymes associated with different stages of development. Two key findings were that recruitment was associated with mRNA expression of cytochrome P450 side-chain cleavage and aromatase enzymes in granulosal cells and that selection was associated with mRNA expression of the LH receptor and 3b-hydroxysteroid dehydrogenase enzyme in granulosal cells.

A second area of focus has been that of mechanisms associated with development of anovulatory ovarian follicular cysts. We have been able to demonstrate that most cysts are not static structures that persist for prolonged periods of time, but in fact more often regress and are replaced by new follicular structures that either ovulate or develop into new cysts. In those studies, intervals between follicular waves in cows with cysts were longer and more variable than cows with normal estrous cycles, mean and pulsatile LH concentrations were increased, but the preovulatory LH surge was absent. Inhibition of LH pulsatile activity with progesterone resulted in initiation of new follicular growth and ovulation in cows with ovarian follicular cysts. Intrafollicular mechanisms associated with dominant ovarian follicular cysts include increased content of estradiol-17b in follicular fluid and increased concentrations of LHr and 3b-hydroxysteroid dehydrogenase mRNA concentrations in granulosa cells of cysts.

The third area of research was associated with subnormal luteal function in beef cattle. It was shown that the short luteal phases that follow the first ovulation postpartum are not due to a defective follicle, but to a premature release of prostaglandin-F2a from the uterus.
