1993 journal article

Response of porcine granulosa cells isolated from primary and secondary follicles to FSH, 8-bromo-cAMP and epidermal growth factor in vitro

Reproduction, 99(2), 577–584.

By: D. Morbeck n, W. Flowers n  & J. Britt  n

MeSH headings : 8-Bromo Cyclic Adenosine Monophosphate / pharmacology; Animals; Cell Division / drug effects; Epidermal Growth Factor / pharmacology; Female; Follicle Stimulating Hormone / pharmacology; Granulosa Cells / cytology; Granulosa Cells / drug effects; Granulosa Cells / metabolism; Ovarian Follicle / physiology; Progesterone / biosynthesis; Stimulation, Chemical; Swine
topics (OpenAlex): Reproductive Biology and Fertility; Animal Genetics and Reproduction; Tissue Engineering and Regenerative Medicine
TL;DR: A cell culture system was developed to study the function of porcine granulosa cells from primary and secondary follicles and found that treatment with FBS, EGF, and FSH increased DNA ingranulosa cell cultures from secondary but not from primary follicles. (via Semantic Scholar)

1992 journal article

Kinetics of Follicle Growth in the Prepubertal Gilt

Biology of Reproduction, 47(3), 485–491.

By: D. Morbeck n, K. Esbenshade n, W. Flowers n  & J. Britt  n

MeSH headings : Animals; Colchicine / pharmacology; Female; Granulosa Cells / cytology; Kinetics; Mitosis; Oocytes / cytology; Ovarian Follicle / cytology; Ovarian Follicle / drug effects; Ovarian Follicle / physiology; Sexual Maturation; Swine / physiology; Theca Cells / cytology
topics (OpenAlex): Reproductive Biology and Fertility; Reproductive Physiology in Livestock
TL;DR: Eight classes of follicles were established such that the number of granulosa cells per cross section doubled in each class and oocyte diameter increased through the first four classes and reached a maximum diameter of approximately 110 microns. (via Semantic Scholar)

1991 article

Duration of Estrous Cycles Subsequent to Two Injections of Prostaglandin F2α Given at a 14-Day Interval in Nonlactating Holstein Cows

Morbeck, D. E., Tyler, H. D., & Britt, J. H. (1991, July 1). Journal of Dairy Science.

By: D. Morbeck n, H. Tyler n & J. Britt  n

author keywords: REPRODUCTION; ESTROUS CYCLE; PROSTAGLANDIN
MeSH headings : Animals; Cattle / physiology; Dinoprost / administration & dosage; Dinoprost / pharmacology; Drug Administration Schedule; Estrus / drug effects; Estrus Synchronization / drug effects; Female; Progesterone / blood
topics (OpenAlex): Reproductive Physiology in Livestock; Genetic and phenotypic traits in livestock; Ruminant Nutrition and Digestive Physiology
TL;DR: This experiment demonstrates that two injections of prostaglandin F2 alpha increase the incidence of estrous cycles greater than 25 d, and stage of the estrous cycle at time of the first injection of prostglandinF2 alpha may contribute to this effect. (via Semantic Scholar)

1991 article

Relationships Among Milk Yield, Metabolism, and Reproductive Performance of Primiparous Holstein Cows Treated with Somatotropin

Morbeck, D. E., Britt, J. H., & McDaniel, B. T. (1991, July 1). Journal of Dairy Science.

By: D. Morbeck n, J. Britt  n & B. McDaniel n

author keywords: PRIMIPAROUS DAIRY CATTLE; SOMATOTROPIN; REPRODUCTION
MeSH headings : Animals; Cattle / metabolism; Cattle / physiology; Estrus / drug effects; Female; Fertilization / drug effects; Growth Hormone / pharmacology; Lactation / drug effects; Least-Squares Analysis; Nutritional Status; Ovulation / drug effects; Postpartum Period / drug effects; Recombinant Proteins / pharmacology; Regression Analysis
topics (OpenAlex): Reproductive Physiology in Livestock; Ruminant Nutrition and Digestive Physiology
TL;DR: Thirty-two primiparous Holsteins were assigned to receive 0, 5.15, 10.3, or 16.5 mg/d recombinant bST and the rate of detection of estrus decreased with dose of bST, resulting in a longer interval to first insemination, and the relationship between metabolism, milk production, and reproduction over all doses of b ST was determined.
