The Intestinal Platyhelminths Of Southwestern And Central West Virginia Amphibia And Relationships Between The Degree Of Infestation And Habitat Of Amphibians And Sex Of Host, Stanley B. Mills

Theses, Dissertations and Capstones

In April and May, 1977, 397 (14 species) amphibians were collected from southwestern and central West Virginia and examined for parasites. Five species of trematodes and two species of cestodes were found from 93 hosts. The total of 397 amphibians was subdivided, for convenience, into six categories of amphibians; aquatic male and female, terrestro-aquatic male and female, and terrestrial male and female. Nine of 24 (37.5%). female aquatic amphibians was the highest incidence found, while terrestro-aquatic females contained the highest mean number (6.0) worms per incidence, and parasite loads of host. Hosts, each platyhelminth specimen are given.

G77-339 Price Spreads For Beef And Pork, Allen C. Wellman

University of Nebraska-Lincoln Extension: Historical Materials

The price spreads for beef and pork are determined by calculating the differences between prices at three marketing levels: farm (live animals), wholesale (carcass or wholesale cuts), and retail (average of retail cuts). Three price spreads, farm-wholesale, wholesale-retail, and farm-retail can be estimated from these prices. Farm-to-retail price spreads for beef and pork represent the total marketnig charges for processing and distribution from farm gate through retail counter and are discussed in this NebGuide.

G77-350 Mineral Nutrition Of Range Beef Cattle, Marvin W. Heeney

University of Nebraska-Lincoln Extension: Historical Materials

Minerals play a very important role in the well-being of the range beef herd. Minerals are essential for practically all of the metabolic functions of the beef animals. Minerals are classified as 1) major and 2) minor or trace. The major minerals include calcium, phosphorus, magnesium, sodium, potassium, chlorine and sulfur. The trace minerals include copper, cobalt, iodine, iron, manganese and zinc.

Each mineral is discussed here in terms of its function, deficiency symptoms and availability in the range beef cattle diet.

G77-355 A Guide For The Control Of Flies In Nebraska Feedlots And Dairies (Revised March 1990), John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Flies, especially stable and house flies, can create serious and costly problems for feedlot and dairy operations. This publication describes several methods for control.

Several species of flies may be in confined livestock facilities during summer. The stable and house fly are the most serious pests. Blow flies also may be present if molasses is in the diet. Horn flies--small blood-feeding flies--may be present in early spring. These flies overwinter as pupae in or near manure pats in range or pasture. If cattle are not present in the grassland when horn flies emerge, they will migrate to confinement cattle. Normally, …

G77-363 Vitamin Requirements Of Beef Cattle, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

Vitamins are organic substances that are required in very small quantities for various metabolic functions. Twenty-five to 30 have been identified, but cattle can synthesize all that are needed of these vitamins in the rumen except for two or three. Even though the supplemental amounts needed of these two or three vitamins (A and possibly D and E) are quite small, a deficiency can have a drastic effect on the animal. The NebGuide discusses these effects.

Movement Of Soil Nitrate Through A Pembroke Soil As Affected By Tillage Method And Time Of Nitrogen Application, Noel T. Johnston

Masters Theses & Specialist Projects

Of all the plant nutrients, nitrogen has been subjected to the most extensive study. The amount of inorganic nitrogen in the soil is small while the quantity needed annually by crops is comparatively large. Of the macronutrients usually applied in commercial fertilizers, nitrogen seems to have the quickest and most pronounced effect on plant growth.

In applying the nitrogen fertilizer for crop use, one must be concerned with placement, form, and availability, and with keeping the fertilizer where it is placed throughout the critical part of the growing season. The nitrogen supply molded by non-leguminous plants is of extreme importance …

Annual Dipping Is A Costly Business, F C. Wilkinson

Journal of the Department of Agriculture, Western Australia, Series 4

When sheep dipping was compulsory, lice infestations and their control could have been costing the sheep industry in Westrn Australi as much as $8 million a year.

On March 1, 1977 compulsory annual sheep dipping ended.

This raises the question of whether an owner should dip sheep.

G77-331 Sampling Feeds For Analyses, Bruce Anderson, Terry L. Mader, Rick Grant

University of Nebraska-Lincoln Extension: Historical Materials

Sampling is the key to accurate feed analyses and properly balancing livestock rations. Here's how to do it.

Accurate feed analyses are needed to balance livestock rations, correctly price hay, formulate least cost supplements, and efficiently allocate homegrown feeds to the proper class of livestock. Sampling is the most important factor affecting accuracy of feed analyses.

The feed value of most forages varies. Therefore, test forages routinely to determine their best and most economical use. With adequate forage testing, you can develop an accurate forage inventory which allows you to efficiently allocate higher quality forage to high-producing livestock and poorer …

G77-326 Clostridial Diseases Of Cattle (Revised September 1981), W.B. Wren, Duane N. Rice

University of Nebraska-Lincoln Extension: Historical Materials

The Clostridial diseases are a group of frequently fatal infections caused by bacteria belonging to the group called Clostridia. These organisms have the ability to form protective shell-like forms called spores when exposed to adverse conditions. This allows them to remain potentially infective in soils for long periods of time, presenting a significant danger to the livestock population. Many of the organisms in this group are also normally present in the intestines of man and animals.

This NebGuide discusses the different clostridial diseases found in cattle.

G77-336 Coccidiosis Of Cattle, Donald L. Ferguson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide contains information on the identification, treatment, and prevention of coccidiosis in cattle.

Coccidiosis continues to be one of the major disease problems for cattle producers. It is caused by microscopic, one-celled parasites, chiefly of the genus Eimeria. Twenty-one species of Eimeria have been reported in cattle. Only two, Eimeria bovis and Eimeria zuernii, are regularly associated with clinical infections in the field.

G77-342 Sowbugs And Pillbugs, Arthur F. Hagen

University of Nebraska-Lincoln Extension: Historical Materials

This publication covers the identification, life history, and control of sowbugs and pillbugs.

Homeowners working around shrubs, in the garden, or along the foundation of the house, frequently find little grayish colored bugs. They often describe them as looking like "little armadillos." What they are finding are sowbugs or pillbugs or both. These creatures are not insects, but belong to the same class of animals as crabs and shrimp.

Vegetation And Environmental Features Of Forest And Range Ecosystems, George A. Garrison, Ardell J. Bjugstad, Don A. Duncan, Mont E. Lewis, Dixie R. Smith

Aspen Bibliography

This is one of the reports developed as part of the Forest-Range Environmental Study (FRES) of the Forest Service, U.S. Department of Agriculture. This report presents descriptive sketches of 34 soil-vegetation units, called ecosystems. These cover all the land area of the 48 contiguous States.

A New Approach To Grain Insect Control, G D. Rimes, M. T. Sexton

Journal of the Department of Agriculture, Western Australia, Series 4

Western Australian farmers now have a legal responsibility to control stored grain insects on their farms.

Ten species of insects, usually referred to collectively as 'weevils', have been 'declared' under the Agriculture and Related Resources Act.

In Western Australia, grain storage insects are not found in standing cereal crops. Thus, it should be possible to set up a clean delivery "pipeline" from the paddock to the C.B.H. bin.

G77-380 Growing Conifers From Seed, Constance A. Harrington

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses how to grow conifers from seed, including technical terms, collecting and storing seed, and planting and care of the trees.

Growing your own conifer trees from seed is fun and gives you the satisfaction of doing it yourself. The pioneers had to be self-reliant. Many of the old trees in Nebraska were started from seeds the pioneers brought with them or ordered from nurseries in the east or Europe. We are fortunate in having nurseries available to supply a wide variety of planting stock. However, many people are still interested in growing their own seedlings. You may …

G77-327 Acute Bovine Pulmonary Emphysema, James H. Bailey

University of Nebraska-Lincoln Extension: Historical Materials

The disease, Acute Bovine Pulmonary Emphysema, has been recognized for many years and under many different names including "Pulmonary Adenomatosis," "Panters," "Lungers," "Bovine Asthma," "Fog Fever," and "Atypical Interstitial Pneumonia." It is characterized by sudden onset of acute respiratory distress with the affected animals producing an audible grunting noise when they exhale.

The cause, occurrence, clinical findings, treatment, prevention and control are covered in this NebGuide.

G77-360 Balancing Corn Silage Dairy Rations, Foster G. Owen

University of Nebraska-Lincoln Extension: Historical Materials

The grain required to balance a ration high in corn silage is much different from the grain needed when feeding high amounts of alfalfa hay. The most common problem is failure to properly balance for protein and calcium. This NebGuide discusses the points to take into account in balancing rations high in corn silage.

University of Nebraska-Lincoln Extension: Historical Materials

Swine producers are often confused by the complexity of the mycoplasmal infections; this fact sheet is an attempt to clarify the information that is currently available about these swine diseases.

Swine producers are often confused by the complexity of the mycoplasmal infections. This fact sheet is an attempt to clarify the information that is currently available about these swine diseases. There are three recognized Mycoplasma spp. of bacteria that cause disease in pigs--Mycoplasma hyopneumoniae, Mycoplasma hyorhinis and Mycoplasma hyosynoviae.

G77-372 Water Requirements For Beef Cattle, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

Water requirements of cattle are influenced by a number of physiological and environmental conditions. These include such things as the rate and composition of gain, pregnancy, lactation, physical activity, type of ration, salt and dry matter intake, and environmental temperature.

The minimum requirement of cattle for water is a reflection of that needed for body growth, for fetal growth or lactation, and of that lost by excretion in the urine, feces, or sweat or by evaporation from the lungs or skin. Anything influencing these needs or losses will influence the minimum requirement.

G77-374 Seasonal Prices For Meat Animals, Allen C. Wellman

University of Nebraska-Lincoln Extension: Historical Materials

Seasonal variations in livestock prices seem to follow a similar pattern from year to year. For some classes of livestock, these seasonal swings in prices have been quite consistent for a number of years; while others have changed considerably over time.

Seasonal price fluctuations result mostly from seasonal supply changes or variations in marketings. For any given year a cyclical change in price may override the season pattern. Seasonal price changes during the 1972-76 period also were influenced by a price freeze, as well as changes in supply and demand.

Seasonal price changes are important factors to consider in planning …

Ryegrass Disease Could Spread, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

The disease annual ryegrass toxicity kills sheep and cattle grazing pastures which contain infected annual ryegrass. In Western Australia the first confirmed outbreak was in 1968 in the Gnowangerup area.

The disease has noe spread over a range of 450 kilometres and with a total area of perhaps 100 000 hectares. because annual ryegrass is the major sown pasture grass in W.A. the disease could spread throughout the South-West.

There are some precautions that can be taken.

Phosphorus Fertilisers For W.A. Farming, Michael D A Bolland

Journal of the Department of Agriculture, Western Australia, Series 4

Phosphorus is one of the major nutrients essential to plants. Eithout the use of phosphorus fertilisers, few soils in Western Australian sagricultural areas would be agriculturaly productive.

Superphosphate has been the major source of phosphorus fertiliser used in W. A..

Now there is a possibility that the alternatives to superphosphate may be cheaper

Economics Of Farm Water Supplies, P P. Eckersley

Journal of the Department of Agriculture, Western Australia, Series 4

The economics of farm water supplies can be studied in two ways. One is to compare the costs of alternative ways of supplying a specified quantity of water to a farm. Another is to calcu;ate how mucha farmer can afford or will pay for a water supply.

I propose to look at these questions from the point of vieew of an eastern wheatbelt farmer, assuming that he must pay the full costs of any water supply provided for his property.

Capital Investment Requirements For A 500, 1,000 And 10,000 Head Cattle Feedlot, Robert Allen, Myron Eighmy, David Jibben

Economics Research Reports (1969 - 2017)

The purpose of this study is to figure the fixed costs of constructing and equipping a 500, 1,000 or 10,000 cattle feedlot given certain assumptions and restrictions, and to analyze those costs in terms of economic efficiency. The fixed costs are divided into six areas of analysis: the equipment of the feedlot, the pole buildings, the concrete flooring for the pole buildings, the feedlot building materials, the feedlot storage equipment and the waste disposal.
