Evaluation Of Carbon Fluxes And Trends (2000e2008) In The Greater Platte River Basin: A Sustainability Study For Potential Biofuel Feedstock Development, Yingxin Gu, Bruce K. Wylie, Li Zhang, Tagir G. Gilmanov

Natural Resource Management Faculty Publications

This study evaluates the carbon fluxes and trends and examines the environmental sustainability (e.g., carbon budget, source or sink) of the potential biofuel feedstock sites identified in the Greater Platte River Basin (GPRB). A 9-year (2000e2008) time series of net ecosystem production (NEP), a measure of net carbon absorption or emission by ecosystems, was used to assess the historical trends and budgets of carbon flux for grasslands in the GPRB. The spatially averaged annual NEP (ANEP) for grassland areas that are possibly suitable for biofuel expansion (productive grasslands) was 71e169 g C m2 year1 during 2000e2008, indicating a carbon sink …

Priority Effects Among Young-Of-The-Year Fish: Reduced Growth Of Bluegill Sunfish (Lepomis Macrochirus) Caused By Yellow Perch (Perca Flavescens)?, Mark A. Kaemingk, Jeffrey C. Jolley, David W. Willis, Steven R. Chipps

Natural Resource Management Faculty Publications

1. When available, Daphnia spp. are often preferred by age-0 yellow perch and bluegill sunfish because of energetic profitability. We hypothesised that predation by age-0 yellow perch could lead to a midsummer decline (MSD) of Daphnia spp. and that priority effects may favour yellow perch because they hatch before bluegill, allowing them to capitalise on Daphnia spp. prior to bluegill emergence. 2. Data were collected from 2004 to 2010 in Pelican Lake, Nebraska, U.S.A. The lake experienced a prolonged MSD in all but 1 year (2005), generally occurring within the first 2 weeks of June except in 2008 and 2010 …

Initial Observations On The Inclusion Of High Protein Distillers Dried Grain Into Rainbow Trout Diets, Michael E. Barnes, Michael L. Brown, Kurt A. Rosentrater

Natural Resource Management Faculty Publications

An initial investigation into the inclusion of high protein distillers dried grain with solubles (HPDDG) in juvenile rainbow trout Oncorhynchus mykiss diets was conducted during a 36-day feeding trial. Four experimental diets containing either 10% or 20% HPDDG with supplemental amino acids, and either with or without phytase, were compared to a fish-meal-based, non-HPDDG, diet. There was no significant difference among any of the diets in total weight gain, percent weight gain, feed conversion ratio, or percent mortality. There was also no significant difference in length, weight, condition factor, hepatosomatic index, viscerosomatic index, or any fish health parameter in fishes …

An Initial Investigation Replacing Fish Meal With A Commercial Fermented Soybean Meal Product In The Diets Of Juvenile Rainbow Trout, Michael E. Barnes, Michael L. Brown, Kurt A. Rosen, Jason R. Sewell

Natural Resource Management Faculty Publications

The inclusion of PepSoyGen (PSG), a commercially-available fermented soybean meal product, was evaluated with juvenile rainbow trout, Oncorhynchus mykiss in an initial 70-day feeding trial, with a supplemental trial involving a subset of the experimental diets continuing for an additional 40 d. Six diets containing 0%, 10%, 20%, 30%, 40%, or 50% PSG, with the PSG directly replacing fish meal, were used in the first trial. There were no significant differences in weight gain or feed conversion ratio between the fish meal-based control diet and diets containing up to 30% PSG. However, weight gain was significantly reduced and feed conversion …

Juvenile Rainbow Trout Responses To Diets Containing Distillers Dried Grain With Solubles, Phytase, And Amino Acid Supplements, Michael E. Barnes, Michael L. Brown, Kurt A. Rosentrater

Natural Resource Management Faculty Publications

Distillers dried grain with solubles (DDGS) was evaluated in juvenile Shasta-strain rainbow trout Oncorhynchus mykiss diets during a 36-day feeding trial. Two experimental diets containing either 10% or 20% DDGS with supplemented amino acids (lysine, methionine, isoleucine, and histidine) and phytase were compared to a fish meal-only control diet. Tanks of trout receiving diets containing either concentration of DDGS weighed significantly less at the end of the trial and had significantly poorer feed conversion ratios than tanks of fish being fed the fish mealonly control. There was no significant difference in individual fish length, weight, condition factor, or any fish …

Soil Phosphorus Availability And Buffering Capacity In Eastern South Dakota Assessed Using Quantity-Intensity Relationships And Diffusive Gradients In Thin Films, Rose Eitemiller

Electronic Theses and Dissertations

Phosphorus (P) availability is influenced by soil properties and depth, creating challenges for nutrient management across agricultural landscapes. This study evaluated two complementary approaches for quantifying P availability and adsorption dynamics in eastern South Dakota soils: Diffusive Gradients in Thin Films (DGT) and P quantity–intensity (Q–I) relationships. The objectives were to (1) quantify bioavailable P using DGT, (2) compare DGT measurements with established soil test P (STP), (3) evaluate Q–I parameters describing P adsorption characteristics, and (4) assess spatial variability in P availability across eastern South Dakota soils. DGT-measured P increased with STP levels and was strongly correlated with Bray-1, …

Organ-Distribution Of The Metabolite 2-Aminothiazoline-4-Carboxylic Acid In A Rat Model Following Cyanide Exposure, Ilona Petrikovics, David E. Thompson, Gary A. Rockwood, Brian A. Logue

Chemistry and Biochemistry Faculty Publications

The reaction of cyanide (CN⁻) with cystine to produce 2-aminothiazoline-4-carboxylic acid (ATCA) is one of the independent detoxification pathways of cyanide in biological systems. In this report, in vivo production of ATCA and its distributions in plasma and organs were studied after a subcutaneous sublethal dose of 4 mg/kg body weight potassium cyanide (KCN) administration to rats. At this sublethal dose of KCN, ATCA concentration was not significantly increased in the plasma samples, however, it was found significantly increased in liver samples. These results suggested that ATCA might not be a good diagnostic biomarker in plasma for sublethal …

Canada Goose Crop Damage Abatement In South Dakota, Troy M. Radtke, Charles D. Dieter

Natural Resource Management Faculty Publications

Canada geese (Branta canadensis) can cause considerable damage to crops during summer when geese are flightless. We evaluated the effectiveness of a program designed to alleviate crop damage on soybeans by Canada geese in South Dakota, USA. The applications of electric fences, feeding stations, and propane cannons reduced the area of crop damage by 90% in 2006 and 80% in 2007, but the timing was important. Fields where abatement practices were applied early in the growing season had less damage than fields where they were applied later. Abatement practices that were properly applied as soon as damage started …

Application Of A Split Luciferase Complementation Assay For Thedetection Of Viral Protein-Protein Interactions, Qiji Deng, Dan Wang, Xiaoxiao Xiang, Philip R. Hardwidge, Radhey S. Kaushik, Thorsten Wolff, Suvobrata Chakravarty, Feng Li

Chemistry and Biochemistry Faculty Publications

Intraviral protein-protein interactions are critical for virus survival in the host. Discovery of such interactions is important to understand molecular mechanisms of viral replication and pathogenesis. The development of a cell-based assay that can be employed to examine systematically viral protein interactions is described. The method, known as the Split Luciferase Complementation Assay (SLCA), is based on the principle that N- and C-terminal domains of luciferase alone do not emit luminescence; however, if fused to interacting proteins the two nonfunctional halves can be brought into close enough proximity through a specific protein-protein interaction to restore the functions of the enzyme …

Natural Resource Management Faculty Publications

Increases in global aquaculture production, compounded with limited availabilities of fish meal for fish feed, has created the need for alternative protein sources. Twinscrew extrusion studies were performed to investigate the production of nutritionally balanced feeds for juvenile yellow perch (Perca flavescens). Five isocaloric (~3.06 kcal/g) ingredient blends, adjusted to a target protein content of 36.7% db, were formulated with 0%, 10%, 20%, 30%, and 40% distillers dried grains with solubles (DDGS) at an initial moisture content of 5–7%db, with appropriate amounts of fish meal, fish oil, whole wheat flour, corn gluten meal, and vitamin and mineral premixes. …

Effects Of Dietary Distillers Dried Grains With Solubles And Soybean Meal On Extruded Pellet Characteristics And Growth Responses Of Juvenile Yellow Perch, Travis W. Schaeffer, Michael L. Brown, Kurt A. Rosentrater

Natural Resource Management Faculty Publications

A 126-d feeding trial was performed to investigate graded combinations of distillers dried grains with solubles (DDGS) and soybean meal (SBM) in diets formulated for yellow perch Perca flavescens. Six experimental diets contained DDGS and SBM at 0 and 31.5% (dry matter basis), respectively (0/31.5 diet), 10 and 26% (10/26), 20 and 20.5% (20/20.5), 30 and 15% (30/15), 40 and 9.5% (40/9.5), and 50 and 4% (50/4) to obtain similar levels of crude protein (mean ± SE = 30.1 ± 0.2%), crude lipid (16.7 ± 0.7%), and digestible energy (13.5 ± 0.2 kJ/g). Fourteen fish (initial individual weight = 19.1 …

Estrus Detection In Mares, Brianna Sandager, Rebecca Bott

SDSU Extension Extra Archives

In a successful horse-breeding program, it is im¬portant to understand the reproductive cycles and be¬haviors of a mare. The reproductive cycle of a mare is called the estrous cycle and lasts an average of 21 days from one ovulation to the next. Estrus is a period of time within the estrous cycle when the mare is recep¬tive to being bred and typically lasts from 5 to 8 days. The efficiency of your breeding program can be af¬fected by your ability or inability to detect estrus in a mare. When a mare is in estrus, it is often referred to as …

Distillers Co-Products For Beef Cows And Heifers, Cody Wright, Sara Winterholler, Megan Peterson

SDSU Extension Extra Archives

In recent years, the expansion of corn-based ethanol production has resulted in an abundance and variety of co-product feedstuffs. As research with distillers co-products has evolved, findings have indicated that the value of the protein and energy content of these feeds is suitable for use in beef cattle diets. In an era of volatile feed costs, these feeds can alleviate some of the burden of high grain prices. The biggest concerns in feeding these products to beef cattle are the potential for high sulfur and phosphorus concentrations, variation in nutrient composition as it changes relative to source and season, and …

Vaccination Of Horses, Rebecca Bott

SDSU Extension Extra Archives

A comprehensive health plan for horses includes vaccinations. Vaccinating a horse prepares its immune system to recognize and diminish the effects of a spe¬cific disease. Vaccines are not 100% effective in disease prevention or management, yet vaccinations can be very beneficial in guarding a horse against illness if the horse is in good general health. Management of overall health in conjunction with a vaccination program is the most effective way to ensure the health of your horse. While vaccinating your horses will help protect them in the event of local disease outbreak, vaccinations alone are not an effective health plan; …

Seed Abundance For Waterfowl In Wetlands Managed By The Illinois Department Of Natural Resources, Joshua D. Stafford, Aaron P. Yetter, Christopher S. Hine, Randolph S. Smith, Michelle M. Horath

Natural Resource Management Faculty Publications

Managed wetlands on public lands in Illinois, United States, provide foraging habitats for migrating and wintering waterfowl. However, few studies have estimated abundances of waterfowl foods in mid-migration regions of North America, yet such information is needed to inform management and conservation decision-making. During 2005– 2007, we used a multistage sampling design to estimate moist-soil plant seed production (kg/ha, dry mass) and energetic carrying capacity at sites managed by the Illinois Department of Natural Resources and modeled variation in seed biomass. Average seed biomass among all sites ranged from 1,030.0 6 64.1 (SE) kg/ha in 2005 to 501.5 6 124.1 …

The Maternal Effect: Carrying The Consequences Of Nutrition Across Generations, Kevin Monteith, Joshua Delger, Lowell Schmitz, Kyle Monteith, Jonathan A. Jenks

Natural Resource Management Faculty Publications

Let’s indulge ourselves in a deer-management fantasy for a moment. I’m sure it won’t be your first time! Imagine you are blessed to own and manage your own block of deer country for several years (for many fortunate readers, this is reality, not fantasy). Although the ground you purchase holds plenty of deer, the overgrown forests and grassy meadows might not be providing the nutrition necessary for these deer to achieve their genetic potential. In addition, the 6-foot high browse line resulting from extreme overabundance of deer is a likely indication of why only scrawny looking bucks are typically harvested …

Feeding The Dry Cow, Fernando Diaz Royon, Alvaro Garcia, Kenneth Kalscheur

SDSU Extension Extra Archives

Under ideal conditions, dairy cows produce milk during 305 days of the year and are dry the remaining 60 (table 1). In reality, feeding for high production should begin during the dry period or towards the end of the previous lactation. With dry periods shorter than 40 days, there’s not enough time to regenerate the mammary tissue; this may result in production losses of 20–40% during the next lactation. Dry periods longer than 70 days do not promote an increase in production and may result in calving difficulties that are costly to the producer.
