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 …

Antipredatory Defense Of Neonatal Pronghorn (Antilocapra Americana) By Yearling Male Pronghorn In Southwestern South Dakota, Christopher N. Jacques, Jonathan A. Jenks

Natural Resource Management Faculty Publications

Antipredatory defense of pronghorn (Antilocapra americana) neonates (≤1 month old) by adult females (>18 months old) is well documented throughout the geographic range of this species. However, reports of male pronghorn defending neonates against predators are limited to a single study in northwestern Wyoming where occurrences were documented of adult males assisting female pronghorn in defending neonates against coyotes (Canis latrans). To our knowledge, defense of neonatal pronghorn by yearling males (12–18 months old) has not been reported previously for this species. We report occurrences of antipredatory defense of neonatal pronghorn by yearling males in southwestern South Dakota

The Influence Of Didymosphenia Geminate On Fisheries Resources In Rapid Creek, South Dakota – An Eight Year History, D.A. James, S.R. Chipps

Natural Resource Management Faculty Publications

The aquatic nuisance diatom Didymosphenia geminata was established in Rapid Creek in the Black Hills of South Dakota in 2002. Shortly thereafter, large declines (>50%) of the naturalized brown trout Salmo trutta population were observed. We evaluated the influence of water resources and D. geminata on (1) declines in brown trout biomass, (2) changes in food resources, and (3) diet of brown trout in Black Hills streams. Drought conditions were largely responsible for trout declines in Black Hills streams. However, comparison of brown trout sizestructure between the pre-D. geminata and post-D. geminata periods revealed that juvenile brown …

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 …

Nesting Ecology Of Greater Sage-Grouse Centrocercus Urophasianus At The Eastern Edge Of Their Historic Distribution, Katie M. Herman-Brunson, Kent C. Jensen, Nicholas W. Kaczor, Christopher C. Swanson, Mark A. Rumble, Robert W. Klaver

Natural Resource Management Faculty Publications

Greater sage-grouse Centrocercus urophasianus populations in North Dakota declined approximately 67% between 1965 and 2003, and the species is listed as a Priority Level 1 Species of Special Concern by the North Dakota Game and Fish Department. The habitat and ecology of the species at the eastern edge of its historical range is largely unknown. We investigated nest site selection by greater sage-grouse and nest survival in North Dakota during 2005 - 2006. Sage-grouse selected nest sites in sagebrush Artemisia spp. with more total vegetative cover, greater sagebrush density, and greater 1-m visual obstruction from the nest than at random …

Moldy Corn For Beef Cattle, Cody Wright, Ben Holland, Russ Daly, Larry Osborne

SDSU Extension Extra Archives

Certain weather conditions and/or physical injury to the plant may result in the development of mold in various parts of the plant. Accumula¬tion of mold and production of mycotoxins may present a risk for livestock producers. However, after examination and analysis, moldy feeds may be able to be used in beef cattle diets—with little or no risk to the health of the animal.

Molt Migration By Giant Canada Geese In Eastern South Dakota, Charles D. Dieter, Bobby J. Anderson

Natural Resource Management Faculty Publications

We captured giant Canada geese (Branta canadensis maxima) in 7 counties in eastern South Dakota during the summer molting period, 2000–2003. We attached very high frequency (VHF) transmitters to 150 adult female geese with brood patches, and leg bands to 3,839 geese. We documented molt migrations using VHF telemetry and indirect band recovery at locations north of South Dakota. Telemetry of radio-collared female geese during the breeding season indicated that 56% of nonbreeders, 81% of unsuccessful breeders, and 19% of successful female breeders embarked on a molt migration. Five of 34 geese that underwent molt migrations moved to …

Post-Yield Relaxation Behavior Of Bovine Cancellous Bone, Travis A. Burgers, Roderic S. Lakes, Sylvana Garcia-Rodriguez, Geoffrey R. Piller, Heidi-Lynn Ploeg

Mechanical Engineering Faculty Publications

Relaxation studies were conducted on specimens of bovine cancellous bone at post-yield strains. Stress and strain were measured for 1000 s and the relaxation modulus was determined. Fifteen cylindrical, cancellous bone specimens were removed from one bovine femur in the anterior–posterior direction. The relaxation modulus was found to be a function of strain. Therefore cancellous bone is non-linearly viscoelastic/viscoplastic in the plastic region. A power law regression was fit to the relaxation modulus data. The multiplicative constant was found to be statistically related through a power law relationship to both strain (p < 0.0005) and apparent density (p < 0.0005) while the power coefficient was found to be related through a power law relationship, E(t, ε)= A(ε)t-n(ε), to strain (p < 0.0005), but not apparent density.

Best Management Practices For Corn Production In South Dakota: Soil Fertility, David E. Clay, Kurtis D. Reitsma

SDSU Extension Circulars

Corn requires sufficient amounts of at least 14 nutrients for optimal production (fig. 7.1). Soil fertility strategies should consider soil residual plant nutrients, cost of fertilizer relative to the value of corn, and management techniques that increase efficiency.

Best Management Practices For Corn Production In South Dakota: Tillage, Crop Rotations, And Cover Crops, Dwayne L. Beck, David E. Clay, Kurtis D. Reitsma

SDSU Extension Circulars

Historically, tillage and cultivation were used to manage residue, diseases, insects, weeds, and soil compaction. Tillage equipment that has been used includes molderboard plows, discs, cultivators, rippers, and chisel plows. Conservation practices and innovations in production tools (i.e., planters, herbicides, and genetically modified crops) provide farmers with the opportunity to minimize losses.

Dairy Profitability 101: Milk Quality And Feed Efficiency, Alvaro Garcia

SDSU Extension Extra Archives

In very simple terms, dairy profitability can be defined as the difference between milk prices and the cost of production, multiplied by the pounds of milk produced. Thus, milk prices, the cost of production, and the pounds of milk produced are the three critical components for dairy profitability. Therefore, it is very important for producers to have a firm grasp on the three components (price, cost, and volume) of this equation and attempt to modify them in their favor. When milk prices are high and input costs low, producers should use all possible means to improve production and increase gross …

Best Management Practices For Corn Production In South Dakota: Corn Growth And Development, Kurtis D. Reitsma, Sharon Clay, Robert G. Hall

SDSU Extension Circulars

Corn growth is influenced by cultural practices and available natural resources. The rate of growth and development changes during the season (fig. 1.1). In South Dakota, water and nitrogen (N) are important resources that limit yield. Other factors that reduce yield include disease, insects, weeds, and deficiency of other plant nutrients. For example, disease and insect infestations can reduce water and nutrient uptake or severely damage the plant to the point of yield loss. Weeds compete with the crop for water, nutrients, and light. Stress from temperature and water extremes affects nutrient availability, often increasing pest population and occurrence and …

SDSU Extension Circulars

Corn diseases can be separated into 1) seed and seedling diseases, 2) root-infecting nematodes, 3) leaf diseases, 4) rusts, 5) stalk rots, and 6) ear and grain molds. Yield losses can result from diseases directly reducing yields or from harvestability, spoilage, or marketing and/or use issues associated with mycotoxin contamination. See Table 9.1 for corn disease management information. Attention to optimal seed quality, hybrid selection, seed treatments, weed and insect control, crop rotation, soil fertility, irrigation, and prompt harvest can reduce disease impacts. This chapter discusses aspects of recognizing and managing South Dakota corn diseases.

Judging South Dakota Rangelands For Livestock And Wildlife Values, James R. Johnson, L. Michael Sterling

SDSU Extension Circulars

Judging South Dakota Rangelands for Livestock and Wildlife Values is a major advance in the approach to contest judging of South Dakota rangelands. For 25 years beginning in the mid-1970s, range judges identified plants and determined range site, range condition, and management practices for a given set of goals (Johnson et al., EC 731, 1979). In the mid-1990s, the need for a more contemporary judging contest was clear. Oklahoma led the way by changing the National Range Judging Contest in 1994. A year later, South Dakota followed. Several years of field tests and multiple revisions resulted in the current manual.
