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

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 …

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. …

This 3-year study evaluated the effect ofglycerin supplementation on ewe reproductive efficiency,blood glucose and insulin concentrations. Mature Polypayand Rambouillet ewes (n = 225) were orally dosed withglycerin following estrus synchronization at rates of 0, 50,100, 200 or 300 g/hd. In year 3 an additional 16 ewes weresupplemented (SUP) with 0.57 kg of range cake for 21 daysprior to breeding. Blood samples were collected (n = 25ewes) for 10 hours post drenching. Blood was analyzed forinsulin and glucose concentrations. Ewes were exposed torams for 35 days. Pregnancy was determined byultrasonography evaluation. Number of lambs born per eweexposed was not different (P …
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
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 …

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 …

Preference Of White-Tailed Deer For Corn Hybrids And Agricultural Husbandry Practices During The Growing Season, Joshua A. Delger, Kevin L. Monteith, Lowell E. Schmitz, Jonathan A. Jenks
Preference Of White-Tailed Deer For Corn Hybrids And Agricultural Husbandry Practices During The Growing Season, Joshua A. Delger, Kevin L. Monteith, Lowell E. Schmitz, Jonathan A. Jenks
Natural Resource Management Faculty Publications
Damage to field corn (Zea mays) by white-tailed deer (Odocoileus virginianus) can be substantial, resulting in millions of dollars lost annually. Numerous methods exist to minimize deer depredation, but all have met with varying degrees of success. Currently, little information is available on preference of white-tailed deer for corn hybrids during the growing season and how that preference might affect depredation patterns. We used adult female white-tailed deer in captivity to study the effect of herbicide treatments on deer-use (treatment versus no treatment) of corn in 2005 and to document preference among specific corn hybrids in …

A Review Of Flavobacterium Psychrophilum Biology, Clinical Signs, And Bacterial Cold Water Disease Prevention And Treatment, Michael E. Barnes, Michael L. Brown
A Review Of Flavobacterium Psychrophilum Biology, Clinical Signs, And Bacterial Cold Water Disease Prevention And Treatment, Michael E. Barnes, Michael L. Brown
Natural Resource Management Faculty Publications
Flavobacterium psychrophilum is a ubiquitous bacterium in the aquatic environment, particularly in freshwater [1]. As the etiological agent of bacterial coldwater disease, it is a serious fish pathogen causing substantial economic losses and rearing difficulties to both commercial and conservation aquaculture [2]. This review paper describes the epidemiology, clinical signs, prevention, and treatment of the fish diseases attributed to this pathogen, which are similar despite the different geographic labels. In addition, the basic biology of F. psychrophilum and the techniques required for successful bacterial culture, isolation, and identification are discussed.
An Assessment Of The Lethal Thermal Maxima For Mountain Sucker, Luke D. Schultz, Katie N. Bertrand
An Assessment Of The Lethal Thermal Maxima For Mountain Sucker, Luke D. Schultz, Katie N. Bertrand
Natural Resource Management Faculty Publications
Temperature is a critical factor in the distribution of stream fishes. From laboratory studies of thermal tolerance, fish ecologists can assess whether species distributions are constrained by tolerable thermal habitat availability. The objective of this study was to use lethal thermal maxima (LTM) methodology to assess the upper thermal tolerance for mountain sucker Catostomus platyrhynchus, a species of greatest conservation need in the state of South Dakota. Adult fish were captured from wild populations in the Black Hills of South Dakota and acclimated to 20, 22.5, and 25 °C. Four endpoints (3 sublethal, 1 lethal) were recorded, with death …

The Equitarian Initiative: International Humanitarian Aid Using Horses, Angela Gebhart
The Journal of Undergraduate Research
This harrowing comment from a Mexican laborer echoes the worldwide importance of working horses, mules, and donkeys. For many in the United States, a horse is a source of recreation, a sport vehicle of sorts, a decoration, or a pet. For most other parts of the world, a working equid (horse, donkey, or mule) is a family’s sole vehicle, a day laborer, and the only constant source of income available. Many of these communities lack a steady food source for the animals, much less a competent veterinarian; thus, the world’s veterinarians treat only about 10% of the world’s total equid …
