University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the importance of submitting proper specimens to the veterinary diagnostic laboratory as an aid in diagnosing infectious diseases, feed imbalance, or animal poisoning.

To comprehend the reasons for failures in disease diagnosis at veterinary diagnostic laboratories, it is important to understand what disease is, what causes disease, how the animal resists disease (becomes immune), and what happens to the animal if disease develops and the animal does not become immune.

According to Stedmans Dictionary, disease is an interruption, cessation or disorder of body functions, systems or organs. Some diseases may be obvious to the untrained eye, …


G89-929 Consequences Teach Responsibility, Herbert G. Lingren Jan 1989

G89-929 Consequences Teach Responsibility, Herbert G. Lingren

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to discipline children by letting them experience the consequences of their behavior, and by using "time-outs" and "reverse time-outs."

There are many ways to discipline children. Parents can choose ways that suit them as individuals and that fit their beliefs and values. Letting children suffer the consequences for their behavior is just one of many discipline methods.

Letting children suffer the consequences is a "hassle-free" way to discipline them. Children learn from experiences, just like adults. We call it "learning the hard way." The child learns that every act has a consequence. And, they learn to …

G89-905 Weed Control On Crp Acres (Revised July 1997), Robert N. Klein, Gail A. Wicks, John E. Watkins, Jerry D. Volesky

University of Nebraska-Lincoln Extension: Historical Materials

Establishing perennial grasses on former cropland presents a challenge. Weed control can be accomplished with herbicides, tillage, burning, mowing, and crop competition. The key to weed control is timeliness. Weeds should be controlled on CRP acres to reduce the risk of seeding failure and eliminate possible reseeding costs. Soil moisture must be available for seed germination, seedling emergence, and establishment to be successful in getting stands of grasses and/or legumes. Weeds can quickly and thoroughly consume soil water throughout the upper soil profile and must be controlled to allow grass and legume seedlings to germinate and emerge. In addition, rapid-growing, …

Ec89-119 Hail Damage Assessment And Replant Decisions, Charles A. Shapiro, Timothy A. Powell Jan 1989

Ec89-119 Hail Damage Assessment And Replant Decisions, Charles A. Shapiro, Timothy A. Powell

University of Nebraska-Lincoln Extension: Historical Materials

Hail is one of the many hazards that can damage a growing crop. Early in the growing season a producer has the option to replant a field seriously damaged by hail. The question is, how do you decide if it is worthwhile to replant, and what information do you need to make an informed decision? Factors to consider when deciding to replant are the expected yield reduction due to hail, the cost of replanting, and the yield potential of the replanted crop. Other information needed to make a rational decision is included in this publication, and several examples are given.


G89-953 Soybean Chlorosis Management, Edwin J. Penas, Richard A. Wiese Jan 1989

G89-953 Soybean Chlorosis Management, Edwin J. Penas, Richard A. Wiese

University of Nebraska-Lincoln Extension: Historical Materials

Four management ideas that make it possible to grow soybeans on alkaline soils are covered here.

Chlorosis (yellowing) in soybeans can be a problem wherever soybeans are grown on alkaline soils in Nebraska. Serious chlorosis is likely to occur when the pH of these alkaline soils is 7.5 or higher. Soybean chlorosis problems occur in the Platte and Elkhorn River Valleys and, to a lesser extent, in the Republican and Loup River Valleys, and on high lime soils in central and western Nebraska. Not all high pH soils cause chlorosis of soybeans even though they are alkaline.

Soil tests of …

G89-947 Buying Meat By The Serving, Dennis E. Burson Jan 1989

G89-947 Buying Meat By The Serving, Dennis E. Burson

University of Nebraska-Lincoln Extension: Historical Materials

Buying meat by the serving rather than by the pound can save you money. Determining cost per serving is covered here.

Smart shoppers use cost per serving rather than price per pound in making meat selection decisions. Price per pound can be misleading because all cuts will not yield the same number of servings per pound.

Although some boneless cuts may cost more on a per pound basis, they may be more economical due to less waste. The amount of bone and waste fat determines the number of servings of cooked meat a cut will yield. Cost of the edible …


G89-923 Windbreak Maintenance And Renovation, Jon Wilson, Mike Kuhns Jan 1989

G89-923 Windbreak Maintenance And Renovation, Jon Wilson, Mike Kuhns

University of Nebraska-Lincoln Extension: Historical Materials

What are you doing to maintain your windbreak? Is renovation necessary? This NebGuide can help you decide.

Windbreaks are integral parts of many Nebraska farming and ranching operations. They protect man, animals, crops and buildings from cold winter winds, hot summer winds, and deep snows. Windbreaks prevent wind erosion and provide wildlife habitat.

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains what financial counseling is, who needs it and why, when it is needed, where to find a qualified financial counselor, and more.

What Is Financial Counseling?

Financial counselors help people learn to manage their own financial resources. As a process, financial counseling involves at least two people--the person who counsels, and the person or persons being counseled.

Financial counseling usually extends over a period of time, since most true change does not take place immediately. Ultimately all decisions are left to the person being counseled.

Financial planning involves setting financial goals and objectives, developing an action plan, …


G89-902 Intensive Gardening Techniques, Betty Besal Jan 1989

G89-902 Intensive Gardening Techniques, Betty Besal

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes techniques which will allow the gardener to grow more vegetables where space may be limited.

For some people, a small-sized garden is preferable to a larger one. Smaller gardens require less labor and expense than larger gardens. Decreasing garden size provides more yard space for other activities. The gardener can concentrate soil improvement efforts in a smaller area, and, with careful management, small gardens can produce sufficient vegetables for fresh eating during the growing season, and perhaps extra produce for preserving.


G89-954 A Guide For Managing Poultry Insects (Revised April 1996), John B. Campbell Jan 1989

G89-954 A Guide For Managing Poultry Insects (Revised April 1996), John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Major insect pests of Nebraska's poultry population are identified and treatment recommendations are given.

For many years poultry production in Nebraska has consisted primarily of large operations of layer hens. In recent years, however, broiler production has increased in southeast Nebraska. There are also some large turkey production units. Extreme competitiveness in the poultry industry has resulted in narrow cost-profit margins. Poultry operations cannot allow ectoparasitic and nuisance insects to interfere with production, nor can they afford high pest control expenses. For production to be profitable, poultry production must be managed to reduce the incidence of insect pests.

Poultry are …

G89-932 Minimum Center Pivot Design Capacities In Nebraska, William L. Kranz, Derrel L. Martin, Greg Lackas

University of Nebraska-Lincoln Extension: Historical Materials

Factors to consider in choosing an appropriate center pivot design are covered here. Irrigators investing in a center pivot irrigation system need to consider this important question: How much supplemental water is required by the crop? Irrigation system capacity needed to meet crop requirements is defined in units of gallons per minute (GPM) or gallons per minute per acre (GPM/AC). If the system capacity is too low, crop stress occurs during some portion of the growing season. If the capacity is too high, surface runoff may result, or capital investment for the pumping plant and center pivot may be greater …

G89-900 Phytophthora Root Rot Of Alfalfa, John E. Watkins, Fred A. Gray, Bruce Anderson Jan 1989

G89-900 Phytophthora Root Rot Of Alfalfa, John E. Watkins, Fred A. Gray, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Disease cycle, symptoms and management practices for phytophthora root rot are discussed in this NebGuide.

Phytophthora root rot (PRR) is a major cause of seedling death in newly established alfalfa, and causes a progressive decline of established stands in Nebraska. This disease is caused by the fungus Phytophthora megasperma f. sp. medicaginis and occurs in most of the alfalfa producing areas in North America.

The Phytophthora that infects alfalfa is different from the Phytophthora that causes root rot in soybeans. Growers sometimes think the two diseases are the same for the respective crops, but they are two different diseases with …


G89-931 Alfalfa Anthracnose, John E. Watkins, Bruce Anderson Jan 1989

G89-931 Alfalfa Anthracnose, John E. Watkins, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Symptoms, disease cycle and control of alfalfa anthracnose are discussed here.

Forage crops are grown on and harvested from more acres in Nebraska than any other crop. Of the almost 49 million acres of agricultural land in Nebraska, approximately 24 million acres are in hay. Alfalfa production has stabilized at about two million acres.

High feed and forage production costs and periodic droughts have generated increased concern by farmers and ranchers over forage losses from diseases, insects and environmental stresses. Estimates suggest about one-fourth of the U.S. alfalfa hay crop and one-tenth of the seed crop are lost annually to …


G89-989 How To Interpret The New Animal Model For Dairy Sire Evaluation, Jeffrey F. Keown Jan 1989

G89-989 How To Interpret The New Animal Model For Dairy Sire Evaluation, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

In question and answer format this NebGuide addresses changes in genetic evaluations of both dairy cows and sores.

Why is the United States Department of Agriculture (USDA) changing the dairy sire and cow evaluation system?

The answer is simple. The Animal Model for genetic evaluations is more accurate than the old Modified Contemporary Comparison Method (M.C.C.). Previously the major limiting factors to implementing the Animal Model were computing costs and memory requirements. With the advent of new Super Computers, the computations are feasible on a national scale.

What is the Animal Model?

The Animal Model simultaneously evaluates cows and sires …
