Managing Wild Pigs: A Technical Guide, Ben C. West, Andrea L. Cooper, James B. Armstrong

Human–Wildlife Interactions Monographs

Wild pigs are and will continue to be a challenging problem for wildlife managers, landowners, farmers, conservationists, and others. Despite ongoing control programs, wild pigs have increased both their range and population size. Because of this growth, wildlife managers will increasingly be involved in dealing with problems caused by wild pigs traditionally, as well as emerging problems such as landscaping damage in suburban areas. Successful management strategies will depend upon persistent, adaptive, and integrated management programs that incorporate sound biological and ecological information. An integrated management approach, in addition to addressing the biological and ecological aspects of wild pigs, will …

Livestock And Vegetation Responses To Stocking Rate And Grazing System, Justin D. Derner

Range Beef Cow Symposium

Vegetation and livestock responses from a 25 year (1982-2006) grazing system and stocking rate study in the northern mixed-grass prairie at the USDA-Agricultural Research Service, High Plains Grasslands Research Station near Cheyenne, Wyoming are presented here. This study was longest known grazing system X stocking rate study in North America and was one of the few studies to use the same stocking rates for grazing system comparisons. Results from this study have been used to further development of, and validate, rangeland models for tactical (within-year) and strategic (across years) decision support tools for producers.

Where Do They Go When They Die?, Meridith L. Bartley

Mahurin Honors College Capstone Experience/Thesis Projects

Food webs and matrices are vital to understanding feeding relationships and ecology. Adjacency matrices can be employed to present the direct relationships between predators and prey; these binary matrices utilize 0’s to denote no direct link and 1’s to denote a direct link. We analyzed a variety of published food webs ranging from pine forests in the United States to tussock grasslands in New Zealand. The food webs varied in number of distinguishable taxa present, functional diversity, climates and habitats. Consequently, we expect that our results are not specific to a given system. The published food webs lack flows from …

Demographics, Activity, And Habitat Selection Of The Eastern Box Turtle (Terrapene C. Carolina) In West Virginia, Justin Adam Weiss

Theses, Dissertations and Capstones

Little is known about the eastern box turtle, Terrapene c. carolina, in West Virginia. The purpose of this study was to compare demographic data between two populations of box turtles, to determine which environmental parameter(s) influence activity patterns, and to describe the optimal habitat of the box turtles at two study sites (Lake and State Park) at Beech Fork Wildlife Management Area. I observed male-skewed sex ratios and low numbers of juveniles in both populations. Male turtles were larger than females in carapace length, but females were larger in carapace height. Turtles at the Lake site exhibited greater body mass …

Birding In The United States: A Demographic And Economic Analysis Addendum To The 2006 National Survey Of Fishing, Hunting, And Wildlife-Associated Recreation

United States Fish and Wildlife Service: Publications

The following report provides up-todate information so birders and policy
makers can make informed decisions regarding the management of birds and
their habitats. This report identifies who birders are, where they live, how
avid they are, and what kinds of birds they watch. In addition to demographic
information, this report also provides an economic measure of birding. It
estimates how much birders spend on their hobby and the economic impact of these expenditures.

By understanding who birders are, they can be more easily reached and informed about pressures facing birds and bird habitats. Conversely, by knowing who is likely not …

Feeding The World, Challenges And Opportunities For The U.S. Beef Industry, Clint Peck

Range Beef Cow Symposium

Nobody ever said the beef business was going to be easy. But, who knew even 10 years ago how complicated it would be to raise a calf and get it sent off to market. Few could have predicted there would be raging debates over animal welfare and animal rights or “food vs. fuel.” Not long ago the most intense pressure facing cattle ranchers came while slugging it out for market share with chicken. For 20 years we lost so much market share to a burgeoning and highly-integrated poultry industry that we began shifting the nucleus of the U.S. beef industry …

Bull Management And Nutrition, Julie Walker, George Perry, Russ Daly, Ken Olson

Range Beef Cow Symposium

Proper management and nutrition of bulls is essential to ensure cow/calf producers maximize reproductive efficiency and genetic improvement of the calf crop. In addition, the herd bull influences overall herd fertility more than any other single animal, and loss of fertility by a bull can cause substantial loss to a potential calf crop. Each cow produces one calf per year; however, bulls should contribute to the calf crop by 25 to 60 times via siring 25 to 60 calves. Additionally, bulls influence their daughters’ production in the cow herd. Therefore, bull selection can be the most powerful method of genetic …

Explanation Of Statistics Used In This Report

Nebraska Swine Reports

Pigs treated alike vary in performance due to their different genetic makeup and to environmental effect we cannot completely control. When a group of pigs is randomly allotted to treatments it is nearly impossible to get an "equal" group of pigs on each treatment. The natural variability among pigs and the number of pigs per treatment determine the expected variation among treatment groups due to random sampling. At the end of an experiment, the experimenter must decide whether observed treatment differences are due to "real" effects of the treatments or to random differences due to the sample of pigs assigned …

Nutrition During Gilt Development And Genetic Line Affect Reproductive Rate Through Parity 1, Rodger Johnson, Philip S. Miller, Roman Moreno, Matthew W. Anderson, Jeffrey M. Perkins, Kelsey Rhynalds, Trevor J. Glidden, Donald Mcclure, Thomas Mcgargill

Nebraska Swine Reports

Effects of allowing gilts ad libitum access to feed until breeding age or developing them with 25% energy restriction from 123 days of age to breeding on reproductive success through parity 1 were studied with a total of 639 gilts of two lines that differ in lean growth and reproduction. Gilts of the two lines had common sires, an industry maternal line, but dams were from different populations. One line of gilts, LW x LR, represented standard industry Large White x Landrace cross females. The other gilts, L45X, were daughters of Nebraska selection Line 45 that has been selected 27 …

In Vivo And In Vitro Expression Of Porcine Zinc Transporter (Znt) 1 Mrna, Huyen Tran, Phillip S. Miller, Thomas E. Burkey

Nebraska Swine Reports

Preliminary experiments were carried out to evaluate in vivo expression of zinc transporter (ZnT) 1 mRNA in a panel of tissues obtained from weaned pigs and to evaluate in vitro changes in Z n T l mRNA in a porcine jejunal epithelial cell line (IPEC-J2) treated with low (40 yM) or high (80 yM) concentrations of zinc sulphate (ZnSO,) or, in a separate experiment, with low (50 yg/ml) or high (1 00 yg/mL) concentrations of antibiotics (as gentamicin; GENT). Lipopolysaccharide (LPS; 10 ng/mL) was included as a negative control in both experiments. Zinc transporter 1 mRNA was detected in all …

Effect Of Dam Parity On Litter Performance And Passive Immunity, Erin E. Carney, Huyen Tran, Justin W. Bundy, Roman Moreno, Matthew Anderson, Jeffrey Perkins, Philip S. Miller, Thomas E. Burkey

Nebraska Swine Reports

Preliminary experiments (reported in the 2008 Nebraska Swine Report) suggest that progeny health status may be affected by dam parity. However, the preliminary experiments only included a small population of sows and their progeny. Therefore, the objective of the current experiment was to evaluate litter performance and the production and passive transfer of immunoglobulins (Ig) in dams (P1 vs. P4) and their progeny. Litter birth weight tended (P < 0.10) to be greater for P4 progeny compared to P1 progeny. No effects of dam parity were observed on circulating Ig in dams during gestation or at parturition. However, concentrations of IgA tended (P < 0.09) to be greater for P4 sows compared to P1 gilts in samples of colostrum and milk and serum IgG concentrations were greater (P < 0.02) for P4 progeny compared to P1 progeny across all preweaning samples. These results suggest that litter performance and health status may be affected by dam parity.

Selection For Immune Responses To Porcine Circovirus (Pcv2) To Decrease Incidence Of Porcine Circovirus Associated Disease (Pcvad), Jared S. Bates, Roman Moreno, Alan R. Doster, Rodger Johnson

Nebraska Swine Reports

Genetic and environmental effects on incidence of Porcine Circovirus Associated Disease (PCVAD) and immune responses to Porcine Circovirus 2 (PCV2), and their relationships with body weights were studied in 3,440 pigs of the Nebraska litter size selection lines. Pigs were weighed at birth, weaning, 65, and 180 days of age and scored for symptoms of PCVAD every 10 days from 70 to 180 days of age. Necropsies were performed to confirm accuracy of scoring. PCV2 viremia, and anti bodies to PCV2, Porcine Reproductive and Respiratory Syndrome Virus, Myco plasma hyopneumoniae and Actino bacillus pleuropneumoniae were measured in serum from blood …

Nebraska’S 8 Great Natural Wonders, Paul A, Johnsgard

Paul Johnsgard Collection

FOR MANY PEOPLE, Nebraska is part of a large, indefinite segment of the central United States dismissively known as “flyover country,” which is best observed through a jet’s window from at least 30,000 feet and while sipping a cool drink. I like to think of such persons as “flyover people,” who have probably never known, at close range, the wonders of our state’s natural landscapes. In the traditions of those romantic souls who would like to visit the seven natural wonders of the world, I humbly offer my own suggestions for visiting Nebraska’s inherent wonders. They are not ranked in …
