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, …

G95-1244 Ventilation Fans: Efficiency And Maintenance, David P. Shelton, Gerald R. Bodman

University of Nebraska-Lincoln Extension: Historical Materials

This publication describes efficiency and design factors to consider when selecting a ventilation fan. Basic maintenance procedures needed for efficient operation are also discussed.

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.

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 …

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 …

Ec95-745 Managing Livestock Odors: Principles, Assessment And Planning, Richard K. Koelsch

University of Nebraska-Lincoln Extension: Historical Materials

Odors associated with livestock manure represent a growing challenge for livestock producers. Livestock production trends such as more animals per farm and expanded reliance upon manure storage have added to the odor muisance. Implementing other environmentally friendly practices such as manure nutrient management and maintenance of surface crop residues for soil conservation also have resulted in additional odor challenges.

Odors originating from livestock wastes are a common source of irritation between producers and neighbors. Confrontations may lead to more stringent local zoning regulations, greater scrutiny of other farm environmental issues, and litigation.

This publication summarizes the underlying causes of livestock …

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.

G95-1236 Developing Beef Quality Assurance, Dicky D. Griffin, Louis Perino, Don Hudson

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 …
