Productivity Of Two Utah Deer Herds As Related To Nutrition, Clarence Leon Pack

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of mule deer occupying deer management units 53 and 54 in south central Utah was conducted from August, 1971 to May, 1974 to determine food habits, caloric requirements, dietary nutritional levels, and productivity. Transects, fecal analyses, weight data, classification counts, and forage analyses were used to accomplish these objectives.

Food habits of deer on the two units were similar, except for higher use of scrub oak on unit 53 and higher use of snowberry on unit 54.

Deer on unit 54 were significantly larger than those on unit 53. Thus, their caloric requirements also were significantly higher.

G76-321 Use Of Energy Values In Ration Formulation, Paul Q. Guyer

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide contains information on the use of high energy values in ration formulation.

Ruminants digest feedstuffs primarily by fermentation in the rumen. This allows ruminant animals to use both roughages and grains as sources of carbohydrates for energy. Part of the carbohydrates pass through the rumen and are digested in the abomasum and small intestine. Most carbohydrates in feeds are converted to either acetic, propionic or butyric acid by rumen bacteria and protozoa. These short chain fatty acids are then absorbed through the rumen wall into the blood stream and eventually are used for energy in body tissue.

The Influence Of A Nutrition Education Program On Preschool Children, Nida Diane Houston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study on the influence of nutrition education experiences was conducted in the Child Development Preschool Laboratory at Southern Utah State College in Cedar City, Utah, with thirty-two preschool children. Sixteen of the children were exposed to nutrition experiences through food activities and stories.

It was found that the sixteen children who were involved in the fifteen nutrition experiences significantly increased their knowledge of nutrition concepts and further modified their own personal food choices. The control group, which was not exposed to nutrition activities, made no significant change in knowledge of nutrition concepts and no modification of personal food choices. …

Heg75-12 Nebraska Master Mix, Harriet Kohn

University of Nebraska-Lincoln Extension: Historical Materials

The Nebraska Master Mix can be used to make many dishes easily. The homemade mix offers the advantage, over bought mixes, of choosing your own combination of ingredients. For example, you may want to try the whole wheat version with margarine for a deliciously different mix. Simple meals and leftovers can be sparked up by adding a homemade hotbread or other food made from the Nebraska Master Mix.

The Nebraska Master Mix is lower in fat than some but gives very good results. Sugar has been reduced in some of the recipes, but other ingredients have been used to enhance …

Food, Nutrition, And Health, Problems And Prospects, D. K. Salunkhe

Faculty Honor Lectures

Food, nutrition, and health - and their complex interrelationships - are necessities of life. Basically, nutrition depends on food; health depends on nutrition. Everyone needs to have enough good quality food to sustain himself. Satisfying that need on a world basis must be of concern to each of us.

Although accurate data are lacking, it is estimated that more than two-thirds of today's world population is afflicted by hunger and/ or malnutrition. Almost 300 million children are suffering physical and, probably, mental damage because of insufficient food. This evidence points to one of two conclusions: we have either too many …

Nutrition Of Sheep Grazing Foothill Big Game Range In Spring, Kurt J. Kotter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sheep with esophageal fistulas were used to determine the daily intake, nutritive content and digestibility of forage at three periods and two stocking intensities during the spring of 1972 on a typical foothill range in northern Utah.

Heavy grazing under a season-long regime did not influence the concentrations of dietary chemical components when compared to moderate grazing; however, it did depress the digestibility of cellulose and organic matter. There was a significant decline in the dietary chemical components due to forage maturation. Digestibility of organic matter and cellulose were significantly higher in the early spring as compared to late spring. …

G74-117 Alfalfa In Swine Diets (Revised November 1988), Duane Reese, D. Murray Danielson

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska ranks first in dehydrated alfalfa meal and seventh in alfalfa hay production in the United States, with production in all counties of the state. With this availability of alfalfa, its use in swine diets should be considered.

The performance and economic considerations of alfalfa in swine diets are detailed here, and information on mixing diets is provided.

G74-149 Bloat Prevention And Treatment (Revised July 1996), Dale Grotelueschen, Richard J. Rasby, Don Hudson, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Bloat is a form of indigestion marked by an excessive accumulation of gas in the rumen. Immediately after cattle consume a meal, the digestive process creates gases in the rumen. Most of the gases are eliminated by eructation (belching). Any interruption of this normal gas elimination results in gas accumulation or bloat.

This NebGuide discusses the types of bloat which may occur in cattle and methods to prevent and treat bloat.

G74-125 Oats In Swine Diets (Revised December 1981), Ernest R. Peo, Donald B. Hudman, Mike Brumm

University of Nebraska-Lincoln Extension: Historical Materials

Oats are not considered a standard feed grain in swine diets in Nebraska because of the small acreage planted. However, oats can be used by all ages of swine with some limitations. The feeding value of oats is 80 percent that of corn. With proper formulation, limiting the amount of oats in diets will cause no reduction in swine performance. The nutritive content of a feed grain is the primary factor in determining its use. This NebGuide discusses the processing of oats for swine diets, gestation diets, lactating diets, starter diets, and growing-finishing diet.

G74-166 Creep Feeding Beef Calves, Richard J. Rasby, Ivan G. Rush, James A. Gosey

University of Nebraska-Lincoln Extension: Historical Materials

Effects of creep feeding calves are covered here. Gross income of the cow/calf enterprise is partially dependent on weaning weight of the calves. Three possible non-genetic ways of increasing calf weaning weight are to increase milk production of the dam, increase forage consumption of the calf, or provide supplemental feed to the calf to increase nutrient intake. Management practices exist to increase standing forage quality, but management of that grass for the calf only is difficult. Likewise, increasing milk production of the dam requires greater feed inputs and possibly supplemental feed. Creep feeding studies consistently have shown an increase in …

G74-170 Nitrates In Livestock Feeding, Richard J. Rasby, Rick Stock, Bruce Anderson, Norman R. Schneider

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes symptoms, causes, prevention and treatment of nitrate poisoning in livestock.

Nitrate poisoning in cattle occurred long before the use of nitrogen fertilizers. In the late 1800s there were reports of cornstalk poisoning in Nebraska, and nitrate poisoning from oat hay in North and South Dakota and from weeds in the high-organic matter soils in Florida and Wisconsin.

Nitrate concentrations in feeds for livestock depends more on plant species and environmental conditions prior to harvest than on the amount of available nitrogen in the soil.

Nutritional Components Of The Standing Plankton Crop In Mississippi Sound, Mohammed Saeed Mulkana, Walter Abbott

Gulf and Caribbean Research

A study on seasonal changes in the nutritional components of standing plankton biomass was made from 20 April 1965 to 6 September 1966. Plankton were separated into net plankton and nannoplankton fractions. Nannoplankton3 standing biomass exceeded by 72 times that of net plankton.

Although protein and carbohydrate levels were higher in net plankton on a unit weight basis, total nutrients available from nannoplankton were substantially higher. Some seasonal trends were apparent as changes in the standing biomass in net plankton. Nannoplankton exhibited no seasonal trends. Lipid and caloric values of net plankton showed seasonal trends similar to those shown by …

Uptake And Distribution Of Mineral Elements By Burley 21 Tobacco As Influenced By Nitrogen Nutrition And Suckering Practice, J. L. Sims, W. O. Atkinson

Agronomy Notes

Knowledge of nutrient content of tobacco and of removal of nutrients from soil is essential to developing sound fertilization practices for tobacco. Quantities of nutrient elements taken·up by tobacco vary widely. This is because of variations in variety, soil fertility level, fertilizer application, soil moisture, plant population, and other environmental and cultural factors . We conducted the present study to determine the effects of applied N and suckering practice on the content of mineral elements in certain plant parts of burley tobacco.

Yield And Value Of Burley 21 Tobacco As Influenced By Nitrogen Nutrition, Suckering Practice, And Harvest Date, J. L. Sims, W. O. Atkinson

Nutritive Values Of Russian Wildrye, Crested Wheatgrass, And Intermediate Wheatgrass Grazed By Cattle On Utah Foothill Ranges, George W. Mitchell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparative index to digestible nutrients was established for Russian wildrye, crested wheatgrass, and intermediate wheatgrass seeded on foothill areas of Utah. The nutritive values of these grasses were compared by the lignin ratio method, the chlorophyllan ratio method, and the in vivo rumen bag process.

Average digestion coefficients computed by the lignin ratio method for dry matter, ether extract, cellulose, and gross energy were highest for intermediate wheatgrass. Protein was more digestible for Russian wildrye. Digestible energy was adequate in all species to meet requirements for late lactation.

Results from the chlorophyllan ratio method were excessively high and were …

Range Nutrition In An Arid Region, Lorin E. Harris

Faculty Honor Lectures

On the mountains, in the valleys, on the foothills and on the deserts of the Intermountain West grow millions of tons of vegetation. The chemical energy stored bv these plants is a potential source of useful energy for man. Some of the plant material has been used for fuel, other has been used as a source of lumber, chemicals, and paper, but the major part of this vast reservO'ir is useful to man because it is utilized by livestock. This native vegetation is grazed by livestock and they convert the plant energy to' high quality, desirable food energy for man.

The Relationship Of Citrus By-Products To The Cattle Industry In Florida, Roland Lloyd Dewing

Graduate Student Research Papers

For many years Florida has led the United States in citrus production and since 1946 has been the source of great quantities of citrus wastes as a result of the production of frozen citrus concentrates. Conversion of these wastes into feed for the rapidly growing cattle industry has provided an effective and profitable way to dispose of these wastes. Since Florida does not produce large amounts of grain or other feed concentrates, the development of citrus feeds has been fortunate both for the citrus and cattle industries in the state. The situation is so fortunate that authoritative sources have maintained …

The Effect Of Range Condition Upon The Production, Nutritive Intake And Digestibility Of Desert Range Forage In Southwestern Utah, J. Kent Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The 65 million acres of winter range in the Intermountain region furnish forage for about five million sheep and four million cattle each winter for approximately six months. These arid ranges are well suited for winter grazing, and are of paramount importance to the livestock industry. Many of these ranges were fully stocked by 1900 and as livestock continued to increase, many winter ranges were seriously over-grazed (Hutchings and Stewart, 1953). Today many of these ranges remain in a deteriorated condition. Forage production has decreased and desirable plants have been replaced by less desirable species.

Little is known about the …

The Care Of The Breeding Sow, P C. Beck

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

PIG-RAISING is a specialised field of animal production, which, to be profitable must incorporate both a scientific and a practical approach.

These two factors must be complementary, for without a sound practical approach, the value of the scientific principles involved, e.g., in breeding and compounding rations would accordingly be reduced.
