2001 journal article

Alteration of activation, growth, and atresia of bovine preantral follicles by long-term treatment of cows with estradiol and recombinant bovine somatotropin

BIOLOGY OF REPRODUCTION, 65(2), 581–586.

By: R. Cushman n, J. DeSouza n, V. Hedgpeth n & J. Britt n

author keywords: apoptosis; estradiol; follicle; growth hormone; ovary
MeSH headings : Animals; Apoptosis; Cattle / physiology; Drug Implants; Estradiol / administration & dosage; Estradiol / pharmacology; Female; Follicular Atresia / drug effects; Human Growth Hormone / administration & dosage; Human Growth Hormone / pharmacology; Immunohistochemistry; Ovarian Follicle / chemistry; Ovarian Follicle / drug effects; Ovarian Follicle / physiology; Proliferating Cell Nuclear Antigen / analysis
TL;DR: E2 induced activation of follicles, bST enhanced survival, and the combination lowered atresia, as well as the combination of bST + E2 decreased apoptosis as shown by decreased fluorescence intensity. (via Semantic Scholar)

2001 journal article

Effect of long-term treatment with recombinant bovine somatotropin and estradiol on hormone concentrations and ovulatory response of superovulated cattle

THERIOGENOLOGY, 55(7), 1533–1547.

By: R. Cushman n, J. DeSouza n, V. Hedgpeth n & J. Britt n

author keywords: cattle; follicle; superovulation; growth hormone; estradiol
MeSH headings : Animals; Body Weight; Cattle / physiology; Drug Implants; Estradiol / administration & dosage; Estradiol / blood; Female; Follicle Stimulating Hormone / pharmacology; Follicular Fluid / chemistry; Growth Hormone / administration & dosage; Growth Hormone / blood; Hormones / blood; Insulin-Like Growth Factor I / analysis; Ovulation / drug effects; Recombinant Proteins / administration & dosage; Superovulation

2000 journal article

Evaluation of numbers of microscopic and macroscopic follicles in cattle selected for twinning

Journal of Animal Science, 78(6), 1564–1567.

By: R. Cushman n, V. Hedgpeth n, S. Echternkamp* & J. Britt n

MeSH headings : Animals; Breeding; Cattle / anatomy & histology; Cattle / genetics; Cattle / physiology; Female; Ovarian Follicle / anatomy & histology; Ovary / anatomy & histology; Pregnancy; Pregnancy, Multiple / physiology; Surface Properties; Twins
TL;DR: It is concluded that ovaries of Control and Twinner cows do not differ in the number of primordial follicles or in thenumber of follicles activated into the growing pool; however,Twinner cows are able to maintain more growing follicles at the secondary and subsequent stages of development.

1999 journal article

Superovulatory response of one ovary is related to the micro- and macroscopic population of follicles in the contralateral ovary of the cow

BIOLOGY OF REPRODUCTION, 60(2), 349–354.

By: R. Cushman n, J. DeSouza n, V. Hedgpeth n & J. Britt n

MeSH headings : Animals; Cattle / physiology; Corpus Luteum / physiology; Female; Follicle Stimulating Hormone / pharmacology; Ovarian Follicle / anatomy & histology; Ovarian Follicle / drug effects; Ovariectomy; Superovulation
TL;DR: It is concluded that superovulatory response in cattle is related positively to the pools of primordial and growing follicles in the bovine ovary. (via Semantic Scholar)

1999 journal article

Technical note: Use of slow-release estradiol and prostaglandin F-2 alpha to induce pseudopregnancy and control estrus in gilts

Journal of Animal Science, 77(11), 2883–2885.

By: R. Cushman n, P. Davis n, U. Boonyaprakob n, V. Hedgpeth n, P. Burns & J. Britt n

MeSH headings : Animals; Delayed-Action Preparations; Dinoprost / administration & dosage; Dinoprost / pharmacology; Estradiol / administration & dosage; Estradiol / pharmacology; Estrus / drug effects; Female; Pseudopregnancy / chemically induced; Swine
TL;DR: It is concluded that a single injection of SRE2 can induce pseudopregnancy and that the CL can be regressed with PGF2alpha, providing a simple method for controlling estrus in gilts. (via Semantic Scholar)
