Kahn, Meredith K (2014-11-25)Eighteen Quarter Horses were utilized in a randomized complete design for a 28 d experiment to evaluate age-related effects on inflammation and cartilage turnover after induction of a single inflammatory insult using ...
-
Krawczel, Peter Downs (Texas A&M University, 2007-04-25)Recommendations for the transportation of lambs from a European Commission, which required rest stops of 6 or 24 h, every 8 h, were evaluated for efficacy of reducing stress indicators using Rambouillet x Suffolk lambs ...

Godfrey, Robert Wayne (Texas A&M University. Libraries, 1987)This study was designed to determine the effects of relocation and season on growth and reproductive parameters of Brahman and Hereford bulls. Hereford bulls from Montana (n = 15) and Nebraska (n = 15) and Brahman bulls ...
-
Iacono, Christa Marie (Texas A&M University, 2007-04-25)The aim of this study was to determine the effects of density and provision of water on behavior, stress, and weight loss in slaughter horses during transport. A 16.2-m long, single deck, semi-trailer was divided into three ...
-
Morgan, Shane (2011-08-08)Experiment I studied the effect of dietary gossypol (G) on antler and body growth traits of red deer stags, whereas Experiment II studied the effect of exogenous melatonin on female red deer reproductive traits. Specifically ...

Nolan, Colleen Jo (Texas A&M University. Libraries, 1987)The influences of age and dietary energy intake on the hypothalamic-hypophyseal-testicular axis of developing Brahman bulls are not well understood. Two experiments were conducted to examine these relationships. In the ...

Stahringer, Rodolfo C. (Texas A&M University. Libraries, 1992)Studies were performed to evaluate postpartum (PP) hormonal profiles in beef cattle. One study examined the effect of aspirin (A) feeding on PP endocrine profiles and reproductive function. The second study evaluated the ...
-
Betts, James Gordon (Texas A&M University. Libraries, 1987)Brahman-cross cows (day 11 or 12 of the estrous cycle) were used to study the effects of prostaglandin-induced luteolysis on the corpus luteum (CL). Four cows (0 h controls) were injected (sc) with saline while 16 cows ...

Laughlin, Andy M. (2011-08-08)Understanding the genes that regulate spermatogenesis and steroidogenesis in the testis is critical for enhancement of stallion fertility. Stallion testicular samples were used to identify candidate genes by cDNA microarrays ...
-
Hansen, Thomas Ross (Texas A&M University. Libraries, 1986)Differentiation of granulosa cells (GC) into luteal cells and mechanisms subserving attainment of puberty are two areas of interest in reproductive endocrinology of the bovine. The first study described herein compared GC ...
-
Carter, Mark (2012-10-19)Transport, a common cause of stress in livestock, has been documented to increase cortisol, and epinephrine in goats. However, little is known about the timing of changes in the immune system in these stressed animals. The ...

Caldwell, Lisa (2010-07-14)Insulin-like growth factor-I (IGF-I) is a growth hormone that acts as a key modulator of the growth axis. Serum and plasma concentrations of IGF-I have been linked to economically important traits in beef cattle. In order ...
-
Shafer, Gentrie (2012-10-19)Residual feed intake (RFI) is one method to identify feed efficient animals; however, this method is costly and time consuming therefore, identifying an indirect measure of RFI is important. Evaluating the glucoregulatory ...
-
Whaley, Patricia Diane (Texas A&M University. Libraries, 1990)Two signal transduction systems, adenylate cyclase (AC) and phosphoinositides (PI), have been implicated in the release of luteinizing hormone-releasing hormone (LHRH). A potential linkage between the systems may involve ...
-
Wu, Tao-Yiao Johnny (Texas A&M University. Libraries, 1991)Two studies were conducted to further understand the involvement of the endogenous opioid peptides (EOPs) in suckling-induced inhibition of LH release. Experiment A in the first study was designed to evaluate the effect ...
-
Laurenz, Jamie Colin (Texas A&M University. Libraries, 1992)The L6 myogenic cell line was utilized in a series of experiments designed to investigate the possible regulatory role of the phosphoinositide signal transduction system in the proliferation of myoblasts in vitro. The ...
-
Grimes, Jeffrey Scott (Texas A&M University, 2006-10-30)Animal research has elucidated the neurobiological substrates and environmental determinants of pain modulation. Despite these advances, relatively little is known about how psychological processes activate pain modulatory ...
-
Tanner, John William (Texas A&M University. Libraries, 1988)A series of experiments was conducted to investigate the regulation of GH synthesis/secretion in cultured bovine adenohypophyseal cells. The effects of: 1) bovine growth hormone-releasing factor (bGRF; 100 nM); 2) ...
