University of Nebraska-Lincoln Extension: Historical Materials

This Neb-Guide gives guidelines for developing a feedlot beef quality assurance program.

The displacement of people from agriculture into other areas of employment has broken the relationship between most consumers and producers. The consumer's lack of knowledge about agricultural production coupled with concern for misuse of technological advances in agriculture has created great concern for the safety of their food supply. Consumers are worried that their food will be contaminated by antibiotics, hormones, and agricultural chemicals. Recently, bacterial contamination of beef has been added to their fears. These concerns, combined with diet and health concerns for eating red meat and …

This NebGuide describes human health risks and symptoms associated with prominent diseases of Nebraska's wildlife. Listed are precautions for minimizing exposure and preventing infection.

Zoonoses (zoe-uh'-no-sez') are diseases that can be transmitted from animals to humans. Wild animals and domestic animals share some disease-causing organisms and either group can transmit diseases to people. Transmission can occur directly through contact with tissues or body fluids of animals. Indirect transmission can occur through insects, ticks and mites that feed on infected animals.

Ec95-1560 Use Of Cultural Practices In Crop Insect Pest Management, Robert J. Wright

University of Nebraska-Lincoln Extension: Historical Materials

This Extension Circular reviews what is known about the effects of rotations, tillage practices, and planting and harvest dates on crop insect management, focusing on major crops in Nebraska.

Before the development of synthetic organic insecticides (pre-DDT era), rotations, tillage practices, planting and harvest dates, and other nonchemical cultural controls were commonly recommended for insect management. Research focused on crop rotation and other cultural practices for insect management. With the development of DDT and later insecticides however, research on nonchemical controls decreased markedly.

With the emergence of the concept of sustainable agriculture in the 1980s, there has been increased emphasis …

Ec95-141 Nebraska's Manure Resource, D. H. Sander, J.E. Power, B. Eghball

University of Nebraska-Lincoln Extension: Historical Materials

Manure is a valuable resource that is sometimes perceived as a liability. For centuries, manure has provided needed nutrients which increased and stabilized food production. With the advent of inorganic chemical fertilizers, the value of manure as a nutrient source decreased because hauling and spreading costs were higher than the cost of chemical feritlizers. In addition, the water content of manure is high and even when the water is removed, its nutrient content is low compared to chemical fertilizers. Therefore, manure has often been viewed in American agriculture as a "waste" to be disposed of rather than a resource to …

G1253 Basic Principles Of Mastitis Control, Jeffrey F. Keown, Paul J. Kononoff

University of Nebraska-Lincoln Extension: Historical Materials

Mastitis is a frustrating, costly, and complex infection. A good, workable, effective preventive control program is presented in this NebGuide.

Mastitis is an inflammation of the mammary gland usually caused by bacterial infection of udder tissues. Except for rare injuries, infectious bacteria or other pathogens, e.g. yeast, fungi, etc., enter the udder through the teat end. Mastitis in both clinical (obvious abnormality, visible to naked eye) and subclinical stages (unseen signs of abnormality, invisible to naked eye) is a frustrating, costly and complex disease that reduces the quality and quantity of milk.

Mastitis results from a complex interrelationship between the …

G95-1262 Feeding The Beef Cow Herd--Part Ii Managing The Feeding Program, Richard J. Rasby, Ivan G. Rush, Don C. Adams

University of Nebraska-Lincoln Extension: Historical Materials

Feed costs are the cow/calf producer's greatest expense in producing a weaned calf. To remain competitive, cow/calf operators must use economical feeding programs. It is important to match the available feed resources with the nutrient requirements of the first-calf-heifer and cow. Both over- and underfeeding the cow herd can lead to high production costs.

Nutrient requirements for heifers calving as 2-year-olds and cows calving as 3-year-olds and older are shown in Table I. Beef cows are seldom fed complete rations where ingredients are weighed daily. Generally, most of a cow's ration is forages such as: 1) summer and winter range, …

An energy efficient ventilation system requires good design and good equipment. Selecting efficient ventilation fans and keeping them in good working condition will keep operating costs down.

G95-1242 Ventilation Fans: Performance, Gerald R. Bodman, David P. Shelton

University of Nebraska-Lincoln Extension: Historical Materials

This publication describes how to use fan performance and system resistance data to achieve the desired effect and efficiency of a ventilation system.

Many people perceive ventilation simply as a fan. However, effective ventilation of a livestock building or the aeration of stored grain requires a complete ventilation system.

A simple ventilation system may consist of fans to move the air, inlets or outlets for air distribution, and manual controls. More complex systems may include ducts, perforated floors, automatic controls, and other components. Regardless, all components must be carefully designed, selected, installed, managed, and maintained to achieve satisfactory results.

G95-1243 Ventilation Fans: Types And Sizes, Gerald R. Bodman, David P. Shelton

University of Nebraska-Lincoln Extension: Historical Materials

This publication describes the most common types of ventilation fans and compares their physical and performance characteristics.

Two general types of ventilation fans are commonly used for agricultural applications. Each type has many different blade diameters, materials, blade shapes, speeds, and motor horsepowers available. The desired airflow rate and the resistance to airflow through the ventilation system, or static pressure capabilities, are the two primary considerations when selecting a ventilation fan. Other considerations include maintenance requirements, noise levels, and energy efficiency.

Ec95-137 Producing And Marketing Proso Millet In The High Plains, D. D. Baltensperger, Drew J. Lyon, R. Anderson, Tom Holman, C. Stymieste, J. Shanahan, Lenis Alton Nelson, Karen L. Deboer, Gary L. Hein, J. Krall

University of Nebraska-Lincoln Extension: Historical Materials

Proso millet, Panicum miliaceum (L.), is a warm season grass capable of producing seed 60 to 90 days after planting. It has been called millet, hog millet, and yellow hog. It has been grown in many countries of the world including China, the former Soviet Union, Afghanistan, Romania, Turkey, and India.

Historically, proso production in the High Plains has been quite variable, depending on the survival of the winter wheat crop, government programs, and market price.

Proso can be used in several ways. Proso millet grain is used as bird and livestock feed in the United States and for livestock …

G95-1135 Estimating Percent Residue Cover Using The Calculation Method, David P. Shelton, John A. Smith, Paul J. Jasa, Roger Kanable

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to use the calculation method to estimate the percent of the soil surface that will be covered with crop residue after using residue-disturbing implements and operations. Leaving crop residue on the soil surface is the easiest and most cost-effective method of reducing soil erosion. Research in Nebraska and other midwestern states found that leaving as little as 20 percent of the soil surface covered with crop residue can reduce soil erosion caused by rainfall and flowing water by one-half compared to residue-free conditions. Greater amounts of residue cover will further reduce erosion.

G95-1132 Estimating Percent Residue Cover, David P. Shelton, Paul J. Jasa, John A. Smith, Roger Kanable

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide briefly describes the direct observation, line-transect, photo comparison, and calculation methods that are used to estimate the percentage of the soil surface covered with crop residue. Leaving crop residue on the soil surface is the easiest and most cost-effective way to reduce soil erosion caused by water and wind. Residue reduces water erosion by lessening the impact of the raindrops, thus reducing the amount of soil that is detached. It also slows flowing water, reducing the amount of soil that can be transported. Residue helps reduce wind erosion by reducing wind velocity near the soil surface and by …

Effectiveness Of Vegetative Filter Strips In Controlling Losses Of Surface-Applied Poultry Litter Constituents, Indrajeet Chaubey, Dwayne R. Edwards, Tommy C. Daniel, Philip A. Moore Jr., D. Jeff Nichols

Biosystems and Agricultural Engineering Faculty Publications

Vegetative filter strips (VFS) have been shown to have high potential for reducing nonpoint source pollution from cultivated agricultural source areas, but information from uncultivated source areas amended with poultry litter is limited. Simulated rainfall was used in analyzing effects of VFS length (0, 3.1, 6.1, 9.2, 15.2, and 21.4 m) on quality of runoff from fescue (Festuca arundinacea Schreb.) plots (1.5 x 24.4 m) amended with poultry litter (5 Mg/ha). The VFS reduced mass transport of ammonia-nitrogen (NH₃-N), total Kjeldahl nitrogen (TKN), ortho-phosphorus (PO₄-P), total phosphorus (TP), chemical oxygen demand (COD), and total suspended …

Freezing And Thawing Of Agricultural Soils: Implications For Soil, Water, And Air Quality, Brenton S. Sharratt, Keith E. Saxton, Jerry K. Radke

Journal of the Minnesota Academy of Science

Most agricultural lands in the USA are subject to subfreezing temperatures. Soil freezing and thawing affects both biotic and abiotic interactions and processes which vary with weather, soil type, land management, and topography. Soil fauna generally undergo physiological changes or rely on locomotion as a means of adapting to frozen soils. Managing faunal populations using soil management may be achievable with a better understanding of winter ecological processes. Many of the thermal, hydraulic, mechanical, and physical properties of soils are altered by freezing and thawing. Soil erosion may be accentuated by soil freezing and thawing as a result of changes …

Frost Tillage For Soil Management In The Northeastern Usa, Harold M. Van Es, Robert R. Schindelbeck

Journal of the Minnesota Academy of Science

Tillage during the winter is typically considered impossible, despite its desirability in some cases. Soil freezing results in net upward movement of water to the freezing zone which facilitates primary tillage or incorporation of amendments. these can be performed during a time window when the frost layer is sufficiently thin to be ripped and the underlying soil is tillable. We evaluated the feasibility of frost tillage and performed an agronomic comparison with spring-tilled soil. Soil conditions conductive to frost tillage occurred during three time windows in the 1991/1992 and two in the 1992/1993 winter at Ithaca, NY. Frost tillage resulted …

Brown· Midrib Sorghum Silage For Midlactation Dairy Cows, R. J. Grant, S. G. Haddad, K. J. Moore, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

Brown midrib sorghum silage was compared with alfalfa, corn, and normal sorghum silages for its effect on performance, ruminal metabolism, and digestive kinetics of Holstein dairy cows in midlactation. Twelve cows averaging 90 ± 5 DIM were assigned to one of four diets in replicated 4 X 4 Latin squares with 4-wk periods. Additionally, 3 ruminally fistulated cows (95 ± 20 DIM) were assigned to the same diets in a 3x 4 Youden square for measurement of ruminal characteristics. Diets were fed as isonitrogenous TMR that contained 65% silage (OM basis). The DMl was greater for the corn and brown …
