ROLES OF ESTRADIOL AND GONADOTROPIN-RELEASING-HORMONE IN CONTROLLING NEGATIVE AND POSITIVE FEEDBACK ASSOCIATED WITH THE LUTEINIZING-HORMONE SURGE IN OVARIECTOMIZED PIGS

BIOLOGY OF REPRODUCTION, 45(3), 478–485.

By: J. Britt n , K. Esbenshade n & A. Ziecik

MeSH headings : Animals; Estradiol / blood; Estradiol / pharmacology; Feedback; Female; Gonadotropin-Releasing Hormone / analogs & derivatives; Gonadotropin-Releasing Hormone / immunology; Gonadotropin-Releasing Hormone / pharmacology; Gonadotropin-Releasing Hormone / physiology; Immunization, Passive; Kinetics; Luteinizing Hormone / metabolism; Ovariectomy; Swine / physiology
TL;DR: It is concluded that 1) estrogen acts at the hypothalamus to inhibit release of GnRH for 54 h and then causes a synchronous release of gnRH, and 2) estrogen act at the pituitary to block its response to Gn RH for 6-12 h and enhances the accumulation of releasable LH, and 3) magnitude of the LH surge is dependent on the amount of Gn RH stimulation.

METABOLIC RESPONSES TO PROTEIN SUPPLEMENTATION AND SLAFRAMINE IN GOATS AND SHEEP FED ROUGHAGE

SMALL RUMINANT RESEARCH, 6(1-2), 73–84.

By: H. Gaskins  n, W. Croom n, J. Fernandez n, J. Vaneys n, W. Hagler n & W. Johnson  n

TL;DR: Blood samples were obtained at hourly intervals for analyses of glucose (GLU), nonesterified fatty acids (NEFA), urea nitrogen (PUN), insulin (INS), glucagon (GLN), thyroxine (T4), and triiodothyronine uptake (T3U), and plasma concentrations of GLU, NEFA and PUN did not differ between species.

EFFECTS OF PRETREATMENT WITH ADRENOCORTICOTROPIN ON ENDOCRINE AND BEHAVIORAL-RESPONSES OF BULLS TO SEXUAL-ACTIVITY

THERIOGENOLOGY, 36(4), 607–618.

By: K. Borg n, K. Esbenshade n & B. Johnson n

author keywords: BULLS; ACTH; HORMONES; SEXUAL BEHAVIOR
TL;DR: Exogenous ACTH administration suppressed reproductive behaviors of bulls and altered secretion of cortisol, growth hormone and testosterone, providing evidence that specific mating behaviors of the bull can be influenced by circulating steroids. (via Semantic Scholar)

PASSIVE-IMMUNIZATION OF THE PIG AGAINST GONADOTROPIN-RELEASING-HORMONE DURING THE FOLLICULAR PHASE OF THE ESTROUS-CYCLE

THERIOGENOLOGY, 35(5), 869–881.

By: K. Esbenshade*

author keywords: PIG; GNRH; IMMUNIZATION; ESTROUS CYCLE
TL;DR: The results indicate that passive immunization of pigs against GnRH before initiation of or during the early part of the follicular phase of the estrous cycle retards follicular development, whereas administration of GnRH antibodies during the latter stages of follicularDevelopment does not have an affect.
