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.

G03-1513 Understanding Fungal (Mold) Toxins (Mycotoxins), Michael P. Carlson, Steveb M. Ensley

University of Nebraska-Lincoln Extension: Historical Materials

Mycotoxins are chemicals produced by fungi (molds) under certain conditions. They are not essential for fungal growth or reproduction, and are toxic to animals or humans.

This NebGuide briefly discusses mycotoxins commonly encountered in grains and feeds used in Nebraska and the mycotoxicoses they cause. Mycotoxin sources and clinical signs, lesions, diagnostic aids and treatment for each mycotoxicosis are listed.

G03-1515 Sampling And Analyzing Feed For Fungal (Mold) Toxins (Mycotoxins), Michael P. Carlson, Steven M. Ensley

University of Nebraska-Lincoln Extension: Historical Materials

Mycotoxins are chemicals produced by fungi (molds) under certain conditions. They are not essential for fungal growth or reproduction, and are toxic to animals or humans. They are naturally present in feed and cannot always be avoided.

The purposes of this NebGuide are to provide information about sampling feeds to detect the presence of mycotoxins in them and about how feeds may be analyzed for mycotoxins.

G03-1514 Use Of Feed Contaminated With Fungal (Mold) Toxins (Mycotoxins), Michael P. Carlson, Steve M. Ensley

University of Nebraska-Lincoln Extension: Historical Materials

Mycotoxins are chemicals produced by fungi (molds) under certain conditions. They are not essential for fungal growth or reproduction, and they are toxic to animals or humans. They are naturally occurring chemicals found in grains, food and feed consumed by humans and animals and cannot be completely avoided. Accordingly, we try to control the amount of such chemicals ingested by humans and animals.

The purpose of this NebGuide is to provide guidelines on use of mycotoxin-contaminated feeds.

Nf03-571 Aspergillus Flavus And Aflatoxins In Corn, Jim Stack, Michael Carlson

University of Nebraska-Lincoln Extension: Historical Materials

The severe weather conditions of the 2002 growing season resulted in an increase in the incidence and severity of aflatoxin contamination of both food grade and feed grade corn in Nebraska.

The mycotoxin called aflatoxin is produced by the grain mold Aspergillus flavus. Not all isolates of A. flavus produced aflatoxin and isolates that are capable of producing aflatoxin do not always synthesize the toxin. Many factors including environmental conditions and host suscepbitility, determine the incidence and severity of grain mold and subsequent mycotoxin contamination.

This NebFact discusses the cause and occurrence of aflatoxin in corn; the effects it has …

Nf03-570 Fumonisins In Corn, Jim Stack, Michael Carlson

University of Nebraska-Lincoln Extension: Historical Materials

During the past two years, millers have rejected some Nebraska food grade corn because it was contaminated with the mycotoxin fumonisin. Most of the contaminated samples and the highest levels of contamination were detected in corn from counties in the eastern half of Nebraska.

Fumonisins are mycotoxins produced by the grain molds Fusarium verticillioides and Fusarium proliferatum. These fungi are commonly found in corn throughout the United States.

This NebFact discusses the cause and occurrence of fumonisin in corn; the effects it has on plants, animals and humans; and management options to minimize fumonisin contamination.

G03-1485 Guidelines For The Prudent Use Of Antibiotics In Food Animals, Katherine Irwin, David R. Smith, Grasso M. Ebako, Steve Ensley, Dicky D. Griffin, Arden Wohlers

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains why antibiotics must be used with care and how to prudently use antibiotics to treat food animals.

Antibiotics are used to improve animal health and productivity. You, the animal caregiver, make important decisions about how antibiotics are finally used in food producing animals. Antibiotics should be used prudently to ensure they are effective, do not leave residues in food, and will continue to benefit man and animals in the future. Are you prepared to make the best decisions about using antibiotics in animals?

G02-1464 West Nile Virus - Getting Prepared, Grasso M. Ebako, Sheila Scheideler, Wayne Kramer, Ron J. Johnson, David R. Smith, Del Wilmot, David J. Steffen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides background information and answers to commonly asked questions about this disease. West Nile Virus is spread by mosquitoes and affects birds (mostly Corvidae such as crows, blue jays and magpies), horses, and people. As West Nile Virus appears in neighboring states, the threat of diagnosing a case in Nebraska becomes more likely.

Mp92-64 The Stable Fly: A Pest Of Humans And Domestic Animals, Gustave D. Thomas, Steven R. Skoda

University of Nebraska-Lincoln Extension: Historical Materials

Many species of flies are pests. Many people, if you were to ask them about flies, would be at least vaguely aware of the potential to flies to transmit disease organisms. But yet, for the most part, a fly is a fly is a fly. Sayings like "It must be about to rain, the house flies are biting" are still common and show a general need for more, readily accessible information, particularly about some of the pest flies.

Stable flies, obligate blood-feeders, are very important pests to the cattle industry and, at times, are pests to other groups (they're most …

G92-1106 Controlling Rats, Scott E. Hygnstrom, Dallas R. Virchow

University of Nebraska-Lincoln Extension: Historical Materials

Ways to recognize rat problems and control rats are covered here.

The Norway rat (Rattus norvegicus) (also known as the common brown rat) is a destructive pest. Found in and around towns and farms throughout Nebraska, these rodents eat and contaminate large amounts of feed, damage structures by their gnawing and burrowing, and spread diseases that affect livestock and humans.
