Evaluation of vaginal electrical resistance as an indicator of follicular maturity and suitability for timed artificial insemination in beef cows subjected to a synchronization of ovulation protocol
Autor: J.F. Zuluaga, J. A. Cartmill, D. A. Cooper, Gary L. Williams, J. P. Saldarriaga
Publikováno v: Animal Reproduction Science. 109:17-26
Objectives were to test the hypothesis that vaginal electrical resistance (VER) could be used to identify cows without a large (10mm) follicle at timed-AI (TAI) following a synchronization of ovulation protocol and thus serve as a prospective decisio

Hormonal patterns in normal and hyperleptinemic mares in response to three common feeding-housing regimens1
Autor: Donald L. Thompson, C. A. Waller, J. A. Cartmill, W. A. Storer
Publikováno v: Journal of Animal Science. 85:2873-2881
We previously reported that a rise in plasma leptin concentrations followed the rise in insulin and glucose in meal-fed horses, whereas horses maintained on pasture had little fluctuations in hormonal patterns. We have also described a hyperleptinemi

Ovarian, hormonal, and reproductive events associated with synchronization of ovulation and timed appointment breeding of Bos indicus-influenced cattle using intravaginal progesterone, gonadotropin-releasing hormone, and prostaglandin F2α1

The objectives of this study were to 1) compare cumulative pregnancy rates in a traditional management (TM) scheme with those using a synchronization of ovulation protocol (CO-Synch + CIDR) for timed AI (TAI) in Bos indicus-influenced cattle; 2) eval

Effect of dexamethasone, feeding time, and insulin infusion on leptin concentrations in stallions1
Autor: J. C. Crowley, W. A. Storer, N. K. Huff, Donald L. Thompson, C. A. Waller, J. A. Cartmill
Publikováno v: Journal of Animal Science. 83:1875-1881
Three experiments tested the hypotheses that daily cortisol rhythm, feeding time, and/or insulin infusion affect(s) leptin secretion in stallions. Ten mature stallions received ad libitum hay and water and were fed a grain concentrate once daily at 0

Endocrine responses in mares and geldings with high body condition scores grouped by high vs. low resting leptin concentrations1
Autor: Donald L. Thompson, N. K. Huff, L.R. Gentry, W. A. Storer, J. A. Cartmill
Publikováno v: Journal of Animal Science. 81:2311-2321
Previous observations from this laboratory indicated that horses with high BCS could have resting plasma leptin concentrations ranging from low (1 to 5 ng/mL) to very high (10 to 50 ng/mL). To study the possible interactions of leptin secretion with

Thyrotropin releasing hormone interactions with growth hormone secretion in horses1
Autor: H. E. Pruett, L.R. Gentry, J. A. Cartmill, Donald L. Thompson, C.C. Williams
Publikováno v: Journal of Animal Science. 81:2343-2351
Light horse mares, stallions, and geldings were used to 1) extend our observations on the thyrotropin releasing hormone (TRH) inhibition of GH secretion in response to physiologic stimuli and 2) test the hypothesis that stimulation of endogenous TRH

Effects of deslorelin acetate implants in horses: Single implants in stallions and steroid-treated geldings and multiple implants in mares1
Autor: C. A. Johnson, J. A. Cartmill, Donald L. Thompson
Publikováno v: Journal of Animal Science. 81:1300-1307
Three experiments were performed to test the following hypotheses: 1) stallions and/or progesterone-estradiol-treated geldings could serve as models for the effects of a single implant of the GnRH analog, deslorelin acetate, on LH and FSH secretion b

Effects of dexamethasone, glucose infusion, adrenocorticotropin, and propylthiouracil on plasma leptin concentrations in horses

Publikováno v: Domestic Animal Endocrinology. 24:1-14
In experiment 1, nine light horse geldings (three 3 x 3 Latin squares) received dexamethasone (DEX; 125 microg/kg BW, i.m.), glucose (0.2 g/kg BW, i.v.), or nothing (control) once per day for 4 days. DEX increased (P0.001) glucose, insulin, and lepti
