Recent Experimental And Clinical Findings In The Skeleton Associated With Loss Of Estrogen Hormone Or Estrogen Receptor Activity, Eric P. Smith, Bonny Specker, Kenneth S Korach Feb 2010

Recent Experimental And Clinical Findings In The Skeleton Associated With Loss Of Estrogen Hormone Or Estrogen Receptor Activity, Eric P. Smith, Bonny Specker, Kenneth S Korach

Ethel Austin Martin Program Publications

Studies on rodent models and rare human disorders of estrogen production or response have revealed an increased complexity of the actions of estrogen on bone. ERalpha disruption in human males results in delayed epiphyseal maturation, tall stature, trabecular thinning, marked cortical thinning, genu valgum and significantly reduced cortical vBMD, but trabecular number is preserved and there is normal to increased periosteal expansion. Aromatase deficiency results overall in a similar phenotype, although less is known about skeletal architecture. Importantly, estrogen replacement in these individuals, even if provided late in the third decade, may normalize aBMD. Less certain is whether there is …

Effect Of Maternal Nutrition On Fetal Adipocyte Development, T.D. Jennings, K.R. Underwood, A.E. Wertz-Lutz, A.D. Weaver

South Dakota Beef Report, 2010

The objective of this experiment was to determine the effects of maternal nutrition on the expression of genes in fetal tissues. Genes of interest were selected because each has been demonstrated previously to influence body composition. Twenty‐two Angus‐cross bred heifers (BW = 1161 ± 19 lbs) randomly were assigned to three dietary treatments. Maternal dietary treatments were formulated and intake was controlled to provide 150% (HIGH), 100% (INT), and 80% (LOW) of maintenance energy requirements for growing pregnant Angus heifers (NRC, 2000). Heifers were on dietary treatment from d 85 to d 180 of gestation, at which point fetuses were …

The Presence Of Growth Hormone Secretagogue Receptor (Ghrelin Receptor) In Metabolic Tissues Of Beef Cattle With Differences In Composition Of Gain, J.S. Jennings, J.A. Clapper, A.D. Weaver, A.E. Wertz-Lutz

South Dakota Beef Report, 2010

Beef steers (n = 72) of similar age, weight (651 ± 3.1 lb), and genetic (Angus crossbred) background were used to determine the effects of growing diet composition (high‐forage vs. high‐concentrate) on the abundance of growth hormone secretagogue receptor (GHS‐R or ghrelin receptor) in metabolically important tissues of beef cattle. At trial initiation (d 0), 8 steers were harvested for initial carcass composition. The remaining 64 steers were allotted, by weight, to pen and treatment was assigned randomly. Treatments were 1) a high‐forage diet fed during the growing period (116 d) followed by a high‐concentrate diet during the finishing period …


Digestion And Metabolism Of Diets Containing Increasing Levels Of Corn Germ, R.H. Pritchard, G.B. Kleinhans Jan 2010

Digestion And Metabolism Of Diets Containing Increasing Levels Of Corn Germ, R.H. Pritchard, G.B. Kleinhans

South Dakota Beef Report, 2010

A novel germ fraction is being generated by the BFrac™4 process. The 20% fat, dry, flowable material is a potential source of concentrated energy to include in Northern Plains feedlot diets. A metabolism study with wethers was conducted to evaluate how ruminants would respond to this additional fat intake in finishing diets. Total collections of urine and feces were conducted on 23 wethers fed pelleted, high‐corn content, iso‐nitrogenous diets that included 0, 10, 20, or 30% germ. Each 6‐d collection period followed 21 d adaptation periods. Increasing BFrac™ germ content caused (P < 0.01) an increase in DMI and a linear (P < 0.001) decrease in DM digestibility, probably due to the effect of DMI. There was a quadratic (P < 0.01) increase in EE digestibility, plateauing at 10% germ. Dietary DE, kcal/g declined linearly (P < 0.01) but DE intake (kcal/d) increased linearly (P < 0.05) because of higher DMI. There was no (P > 0.15) dietary effect on N digestibility, but there …

Respiratory Disease In Young Dairy Calves., A. D. Garcia, R. Daly Jan 2010

Respiratory Disease In Young Dairy Calves., A. D. Garcia, R. Daly

Dairy Science Publication Database

Respiratory disease is the second leading cause of death losses (scours is the first) in un-weaned heifer calves. Respiratory problems have increased by 34 percent in the last twenty years resulting in nearly 21 percent of all newborn calf losses (NAHMS. 2007). Heifers that survive continue to perform poorly as adult cows. In order to prevent this costly problem it is important to address both determinant and predisposing causes.

Relationship Of Circulating Ghrelin And Leptin Concentrations In Beef Cattle Exhibitingdifferences In Composition Of Gain, J.S. Jennings, R.H. Pritchard, K.W. Bruns, D.H. Keisler, A.E. Wertz-Lutz

South Dakota Beef Report, 2010

Beef steers (n = 72) of similar age, weight (651 ± 3.1 lb), and genetic background (Angus crossbred) were used to determine the effects of growing period diet on the relationship of plasma ghrelin and leptin concentrations with growth performance and carcass composition. At trial initiation (d 0), 8 steers were harvested for initial carcass composition. The remaining 64 steers were allotted, by weight, to pen and treatment was assigned randomly. Treatments were 1) a high‐forage diet fed during the growing period (0‐116 d) followed by a high‐concentrate diet during the finishing period (117‐209 d; GRW‐FNSH) or 2) a high‐concentrate …

Enfermedad Respiratoria En Los Terneros Lecheros, Como Prevenirla, A. D. Garcia, A. R. Daly Jan 2010

Enfermedad Respiratoria En Los Terneros Lecheros, Como Prevenirla, A. D. Garcia, A. R. Daly

Dairy Science Publication Database

La enfermedad respiratoria es la segunda causa de muerte (diarrea es la primera) en las terneras lecheras no destetadas. Los problemas respiratorios han aumentado en un 34 por ciento en los últimos 20 años, causando cerca de 21 por ciento de la mortandad de los terneros (NAHMS 2007). Las terneras que sobreviven continúan con un desempeño pobre al convertirse en vacas adultas. Para prevenir este problema, es importante tener en cuenta tanto causas predisponentes como determinantes.


Dealing With Mycotoxin-Contaminated Feeds At Feeding Time, Alvaro Garcia, Bob Thaler Jan 2010

Dealing With Mycotoxin-Contaminated Feeds At Feeding Time, Alvaro Garcia, Bob Thaler

SDSU Extension Extra Archives

Under ideal conditions, livestock should be fed grains and byproducts that are “clean” (i.e., free of fungi and/or mycotoxins). Although feeding clean grains and byproducts is ideal, there are times when clean grains are not available locally and farm finances do not allow for substitution of home-harvested grain with purchased grain. When grains or feeds test positive for mycotoxins, there are several approaches that can be taken to reduce the toxic effects to livestock.

Metabolizability Of Dried Distillers Grains Plus Solubles In Finishing Cattle Diets, R.H. Pritchard, J.W. Mccarthick, J. Knock, D.L. Boggs, C.J. Mueller Jan 2010

Metabolizability Of Dried Distillers Grains Plus Solubles In Finishing Cattle Diets, R.H. Pritchard, J.W. Mccarthick, J. Knock, D.L. Boggs, C.J. Mueller

South Dakota Beef Report, 2010

The feeding value of dried distillers grains plus solubles (DDGS) is a combination of its contributions to protein nutrition as well as caloric intake of cattle. When DDGS is included in diets at levels where dietary CP has been met, the feeding value would primarily be a function of caloric density. A replicated 4 x 4 metabolism study was conducted to measure the caloric value of DDGS at high inclusion levels. Diets were formulated to contain 0, 12, 24, or 36% DDGS. These finishing diets were fed to yearling steers during a 21 d adaptation prior to total fecal and …

Effects Of Molybdenum Supplementation On Performance Of Forage‐Fed Steersreceiving High‐Sulfur Water, K.L. Kessler, K.C. Olson, C.L. Wright, K.J. Austin, P.S. Johnson, K.M. Cammack

South Dakota Beef Report, 2010

There has been on‐going research in the area of the consumption of high‐sulfur (S) water by steers grazing rangeland as well as forage‐fed steers in a feedlot setting. During the summer of 2009, a trial was conducted on the effects of high‐S water in finishing steers supplemented with molybdenum (Mo). The main purpose of the research was to gather data that may aid in the formulation of a supplement to counteract the negative effects of high‐S water consumed by ruminant livestock species in areas where sulfur concentration in water sources is a risk to animal health and performance. The specific …

Effect Of Standing Estrus Prior To An Injection Of Gnrh On Steriodogenic Enzyme Expression In Luteal Tissue, Kaycee Gebhart Jan 2010

Effect Of Standing Estrus Prior To An Injection Of Gnrh On Steriodogenic Enzyme Expression In Luteal Tissue, Kaycee Gebhart

The Journal of Undergraduate Research

Cows detected in estrus around the time of fixed-time AI had increased pregnancy success and progesterone concentrations. Additionally, GnRH following onset of estrus influenced LH pulse frequency and CL formation/function. Therefore our objective was to determine steriodogenic enzyme expression within luteal tissue of cows that were or were not detected in standing estrus prior to an injection of GnRH. Cows were synchronized with the CO-Synch protocol (day -9 100 mg GnRH; day -2 25 mg PGF2α; day 0 100 mg GnRH). Estrus was detected with the HeatWatch system. Location and size of the ovulatory follicle was determined on day 0 …


Working Mothers: Cognitive And Behavioral Effects On Children, Amanda Dejong Jan 2010

Working Mothers: Cognitive And Behavioral Effects On Children, Amanda Dejong

The Journal of Undergraduate Research

Children face several cognitive and behavioral effects that are the result of maternal employment during their early developmental years. In this study, a questionnaire was distributed to thirty-two participants (twenty-eight female, four male) ranging in age from twenty-six to fifty-nine years. All participants had at least one child. Participants provided information about themselves, their spouse (when applicable), and their children, as well as their and their spouse’s work. Several cognitive and behavioral differences were noted between children of working and nonworking mothers. Differences were found in school performance, participation in extracurricular activities, and abnormal behavioral issues.

Agronomy, Horticulture and Plant Science Faculty Publications

Background: Genomic data release for the grapevine has increased exponentially in the last five years. The Vitis vinifera genome has been sequenced and Vitis EST, transcriptomic, proteomic, and metabolomic tools and data sets continue to be developed. The next critical challenge is to provide biological meaning to this tremendous amount of data by annotating genes and integrating them within their biological context. We have developed and validated a system of Grapevine Molecular Networks (VitisNet).

Methodology/Principal Findings: The sequences from the Vitis vinifera (cv. Pinot Noir PN40024) genome sequencing project and ESTs from the Vitis genus have been paired and the …


Dietary Response Of Sympatric Deer To Fire Using Stable Isotope Analysis Of Liver Tissue, W.D. Walter, T. J. Zimmerman, D. M. Leslie Jr., J. A. Jenks Dec 2009

Dietary Response Of Sympatric Deer To Fire Using Stable Isotope Analysis Of Liver Tissue, W.D. Walter, T. J. Zimmerman, D. M. Leslie Jr., J. A. Jenks

Natural Resource Management Faculty Publications

Carbon (δ13C) and nitrogen (δ15N) isotopes in biological samples from large herbivores identify photosynthetic pathways (C3 vs. C4 ) of plants they consumed and can elucidate potential nutritional characteristics of dietary selection. Because large herbivores consume a diversity of forage types, δ13C and δ15N in their tissue can index ingested and assimilated diets through time. We assessed δ13C and δ15N in metabolically active liver tissue of sympatric mule deer (Odocoileus hemionus) and white-tailed deer (O. virginianus) to identify dietary disparity resulting from use of burned and unburned areas in a largely forested landscape. Interspecific variation in dietary disparity of deer …
