Feral Swine Impacts On Agriculture And The Environment, Nathan W. Seward, Kurt C. Vercauteren, Gary W. Witmer, Richard M. Engeman

Sheep and Goat Research Journal

More than 30 species of exotic freeranging mammals have become established in the United States since European colonization (De Vos et al., 1956; McKnight, 1964; Roots, 1976). These species often become serious economic pests and can have grave consequences on their host environments (Cottam, 1956; De Vos et al., 1956; Mayer and Brisbin, 1991). True wild pigs (Suidae) are not native to the United States. Only the collared peccary (Tayassu tajacu; Tayassuidae) that inhabits the southwestern and south-central parts of the United States is native (Mayer and Brandt, 1982; Mayer and Wetzel, 1986). Feral swine (Sus scrofa …

Leptospirosis In The Azores: The Rodent Connection, Gary W. Witmer, Hernani Martins, Lidia Flor

USDA Wildlife Services: Staff Publications

The Azores are Portuguese islands in the North Atlantic Ocean. The culture is very agrarian with a large cattle industry. Unfortunately, there is a chronic leptospirosis problem within the people, livestock, companion animals, and wildlife of the Azores. Introduced rodents play a significant role as maintenance hosts of this disease. We review the situation and make recommendations for reducing the occurrence and hazard of leptospirosis in the Azores. Areas addressed include the need for a better understanding of the epidemiology of the disease and the role of rodents, development of an effective rodent control program, improvements in farm practices and …

Relative Factor Costs Of Wildlife Rabies Impacts In The U.S., Ray T. Sterner, Ben Sun

USDA Wildlife Services: Staff Publications

A comprehensive cost model of wildlife rabies is presented. A total of 11 factors were viewed to comprise the diverse agricultural, insurance, medical, and veterinary expenses associated with rabies (i.e., pet vaccinations, livestock vaccinations, pet replacements, livestock replacements, pre-exposure prophylaxis for humans, post-exposure prophylaxis for humans, adverse medical reactions, animal control activities, public health charges, quarantine costs, and human death settlements). These factor costs form the basis of potential savings to be gained from rabies control activities. Irrespective of incidence, per unit costs and ranges were found to be greatest for livestock replacement, post-exposure prophylaxis, adverse medical reactions, and human …

Keynote Address: Breathing Lessons, J. Russell Mason

USDA Wildlife Services: Staff Publications

Current issues in wildlife damage management and the protection of human health and safety arise from the successful application of traditional methods by state and federal managers. The paradox is that these same methods are increasingly controversial. Within this constraint, management strategies may be difficult to implement. In California, for example, protecting state-threatened foxes could mean killing federally protected golden eagles. In Utah, restoring Gunnison sage grouse may require the sustained lethal suppression of predator populations unless or until habitat can be restored. The obvious fact is that these are unpopular choices, and special interest groups frequently oppose selective intervention, …

Cervid Disease Research At The National Wildlife Research Center, Kurt C. Vercauteren, Mike Lavelle, Dale L. Nolte, Scott E. Hygnstrom, Jason Gilsdorf

USDA Wildlife Services: Staff Publications

The realized and perceived threats of cervid diseases have immense implications for federal and state wildlife management agencies, captive cervid ranchers, hunters, and businesses and economies that rely on recreation associated with deer and elk. Therefore, the spread of diseases, primarily chronic wasting disease and bovine tuberculosis, in wild and captive cervids is of great concern. Research is paramount to closing information gaps associated with all aspects of cervid diseases. The Wildlife Disease Research Program of the USDA APHIS WS National Wildlife Research Center is engaged in considerable research on cervid diseases. Efforts focus on disease epidemiology, cervid ecology, and …

Ec04-219 2004 Nebraska Swine Report, Duane Reese

University of Nebraska-Lincoln Extension: Historical Materials

The 2004 Nebraska Swine Report was prepared by the staff in Animal Science and cooperating Departments for use in Extension, Teaching and Research programs. This publications deals with research on swine reproduction, breeding, health, nutrition, economics, and housing.

Nf04-597 Biosecurity And The Poultry Flock, Dan Mcguire, Sheila Scheideler

University of Nebraska-Lincoln Extension: Historical Materials

What is Biosecurity? Biosecurity is a modern term created out of a need to protect, in our case poultry, from an intentional or unintentional threat from a biological agent. In our everyday management, biosecurity is an endless endeavor to keep viral disease agents and/or the spread of such disease agents at bay. We have learned from our own personal welfare that by keeping our environment clean, i.e., "cleanliness is next to godliness" and by reducing contact with infected people or animals, i.e., "being a good neighbor," we can reduce our chance of catching or spreading disease. This NebGuide discusses what …

Nf04-616 Managing Foliar Diseases Of Winter Wheat With Fungicides Treatment Criteria, Profitability And Products, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

The leaf rust, stripe rust, powdery mildew, tan spot, Septoria leaf blotch and occasionally stem rust comprise the primary foliar disease of wheat in the central Great Plains. In southeast and south central Nebraska, leaf and stripe rusts, powdery mildew and Septoria leaf blotch are the most common and important foliar diseases. Tan spot predominates in the dryland wheat-fallow-wheat or ecofallow cropping systems found in the west central, southwest and Panhandle areas of Nebraska.

This NebFact discusses the treatment criteria, profitability of treatment, and the treatment products and timing of managing foliar diseases of winter wheat with fungicides.

University of Nebraska-Lincoln Extension: Historical Materials

Fungi can cause seed to rot. This publication describes treatments.

Nf04-598 Rabies In Nebraska, Annette K. Bredthauer, David R. Smith

University of Nebraska-Lincoln Extension: Historical Materials

Rabies is a deadly virus infection that can attack the central nervous system of most warm blooded animals, including humans. Rabies is a very old disease. The first recorded description of the disease dates from the 23rd century BC in Babylon. It was rampant in Europe in the 19th century and was carried to the Americas by animals on the early ships.

This NebFact describes rabies in animals and explains how people can protect themselves, as well as their pets or livestock from rabies exposure.

Cardicola Forsteri (Digenea: Sanguinicolidae) From The Heart Of A Northern Bluefin Tuna, Thunnus Thynnus (Scombridae), In The Northwest Atlantic Ocean, Stephen A. Bullard, Robert J. Goldstein, Robert H. Goodwin Iii, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

We report a specimen of Cardicola forsteri Cribb, Daintith, and Munday, 2000 (Digenea: Sanguinicolidae) from the lumen of the heart of a northern bluefin tuna, Thunnus thynnus (Linnaeus, 1758) (Scombridae), that was 218 cm in total length (TL) and caught in the northwest Atlantic Ocean 12 km south of Cape Lookout, North Carolina. The hearts of 12 similarly sized northern bluefin tuna (127–262 cm TL) from George’s Bank, northwest Atlantic Ocean, were not infected. This is the first report of C. forsteri from a wild host and of a sanguinicolid from any scombrid in the northwest Atlantic Ocean. Bluefin tuna …
