G77-386 Wheat In Poultry Rations, T.W. Sullivan, E.W. Gleaves

University of Nebraska-Lincoln Extension: Historical Materials

This publication examines the advantages and disadvantages of wheat as a component of poultry feed.

Wheat is usually considered a source of human food rather than an ingredient for poultry and livestock feeds. This is especially true in the United States, where corn, milo and other feed grains are abundantly produced. In recent years one of every two bushels of wheat produced in the United States has been exported. If world production and supplies of wheat are high, a surplus develops and wheat prices are lowered. When this situation occurs wheat becomes an attractive alternative to corn or milo in …

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.

Some Effects Of Mechanical Deboning On The Composition And The Bioavailability Of Protein And Iron In Turkey Frame Meat, Lowell C. Allred

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Meat was obtained from a single daily lot of turkey frames by mechanically deboning with a Beehive AU 4171 deboner and by hand deboning. The meat was analyzed for protein, fat, moisture, ash, iron, calcium, and 19 amino acids. Mechanically deboned turkey had 68 percent more ash, 74 percent more iron, and nine times more calcium than the hand deboned turkey meat. Other constituents were about equal in the two products. Protein bioavailability tests, including protein efficiency ratio, biological value, net protein utilization, and nitrogen efficiency for growth, did not reveal significant differences between mechanically deboned and hand deboned turkey. …

Reevaluation Of Common Wheats From The Usda World Wheat Collection For Protein And Lysine Content, K. P. Vogel, V. A. Johnson, P. J. Mattern

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The protein and lysine content of wheat can be altered by breeding only if genetic variability exists for these traits. Lysine is a nutritionally limiting amino acid in wheat protein. Protein and lysine analyses of the common wheats of the USDA World Wheat Collection indicated that variability does exist for these traits. Some of the variability for protein and lysine among wheats of the World Collection may not be genetic in origin, because all the 12,000 wheats analyzed were not grown in the same environment. The purpose of this study was to reevaluate selected lines from the World Wheat Collection …

Milk Protein Analysis By Automated Ultraviolet Spectroscopy, R. Ford Wilkinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An automated continuous flow analysis for milk protein utilizing ultraviolet spectroscopy resulted in a correlation coefficient of 0.972 and a standard estimate of error of 0.082 percent protein when 30 samples were compared with the acid orange 12 dye binding method. Milk was solubilized in 95-105 volumes of acetic acid using the Technicon Auto Analyzer II and measured for absorbance at 274 nanometers. No deviation from the standard method due to mastitis and varying milk fat concentration was observed. A theoretical model indicated a possible standard estimate of error 0.059 percent protein due to inter- and intra-breed variation in milk …

Tb33: Utilization Of Amino Acids From Proteins: Manual Of Procedures, Hermon Dehaas, Ellen H. Morse

Technical Bulletins

To meet the protein needs of the newly developing countries and the increasing world population, plant proteins and protein mixtures will be required in larger and larger amounts. The proteins studied in this investigation included an animal and a vegetable protein that are important agricultural products of the United States. While general information about the nutritive quality of these proteins is available, this regional study was designed to contribute to an understanding of the reasons for the quality differences and to provide a basis for formulating protein mixtures of high quality using various protein sources.

Protein And The Pill- A Pivotal Partnership, B. Delworth Gardner

Faculty Honor Lectures

Two fearsome possibilities preoccupy thoughtful men everywhere in the world. These worries are unique to our own age and time. Lord Russell puts it succinctly, "The world is faced, at the present day, with two antithetical dangers: (a) the human race may put an end to itself by a too lavish use of H bombs; and (b) the human population of our planet may increase to the point where only a starved and miserable existence is possible, except for a minority of powedul people."

Each of these dangers has its own characteristics, its own special perils, and its own possibilities …

An Examination Of A Putative System For The In Vitro Synthesis Of Drosophila Tryptophan Pyrrolase, John P. Phillips

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A system, reported by Morrison (1964), for the in vitro synthesis of Drosophila tryptophan pyrrolase has been critically studied. This putative system is based on the addition of a Drosophila "RNA" extract to a Drosophila cell-free protein synthesizing system; the synthesized enzyme is then allowed to catalyze a specific reaction, the product of which is measured by direct adsorption.

The results of this study present a three-fold argument against the interpretation of synthesis of tryptophan pyrrolase in the Morrison in vitro system: (1) RNA from a null-allele, v^36f, stimulated the same tryptophan pyrrolase "activity" in the in vitro …

A Study Of Amino Acid, Protein, Organic Acid And Carbohydrate Changes Occurring During Germination Of Peach Seeds, Lee Chao

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Conditions required for seed germination are different among species. Some seed of tropical and subtropical plants may germinate before the maturation of their fleshy fruit, e.g. papaya species, while seed from most deciduous trees have a period of after-ripening before germination. The after-ripening period, also referred to as rest or dormancy has also been observed in some vegetable crops and ornamental flowers.

Eggs are produced from the feed we give our hens. The number of eggs taht are produced depends upon the amount and quality of the ration. For a hen to lay profitabily she must have a full feed of a properly balanced ration.

This campaign circular discusses what is needed to get the best egg production from your hens.

Cc56-139 Poultry Profit Pointers: Marketing Eggs, Elvin C. Schulte

University of Nebraska-Lincoln Extension: Historical Materials

The egg represents the marketable, finished produce from the laying flock. Poultry raisers should be familiar with eggs and do everything possible to maintain egg quality. Eggs are a valuable human food because they are rich in protein, vitamins and minerals. Like other important protein foods, eggs should be properly handled to protect their quality.

This campaign circular discusses what to look for in the size eggs and how to handle them before taking them market.

The Influence Of Time And Rate Of Application Of Urea Spray On The Yield And Protein Content Of Winter Wheat, Vern L. Marble

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Winter wheat, with an annual average acreage of about 300,000 acres, forms an integral part of the farm economy of Utah.

For many years intermountain agronomists and farmers alike have known dry-land wheat production to be limited by low summer rainfall. In the past 15 years, however, it has become apparent through intelligent research that in many cases lack of nitrogen has been the limiting factor. When this occurs, winter wheat production can be increased by correcting this nitrogen deficiency

Nitrogen Content And Protein Yield Of Alfalfa As Influenced By Variety, William H. Bennett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twenty-four alfalfa varieties, representing four varietal groups, were compared for nitrogen content and protein yield. A highly significant difference between varieties was noted for nitrogen content, and a significant difference for protein yield. Saskatchewan 666 had the highest content in the first cutting, but Ledak 22009 had the highest content in the third. Group differences were not significant. Crop differences were highly significant for nitrogen content, yield of forage, and of protein. In the case of every variety, the third cutting was richer in nitrogen than the second and the seemed was richer than the first. Protein yield, however, was …

The effect of replacing the ten parts of alfalfa meal in a ration with artificially dried Sudan-grass meal on an equivalent protein basis was studied in a growth and body-analysis experiment with two lots of day-old chicks. 2. The chicks of both lots consumed equal amounts of dry matter during the feeding trial. 3. There were no significant differences in the growth rate or composition of the chicks at the end of a six weeks' feeding trial.

The Utilization Of Food Elements By Growing Chicks. Vi. The Influence Of The Protein Level Of The Ration On The Growth Of Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

1. Two rations containing 16 and 22 per cent of protein respectively were fed to newly hatched chicks in two series of feeding trials. In one series the lower protein level was secured by diluting the higher with 30 parts of starch so that the amount but not the quality of the protein was changed. In the other series the amount and quality of the protein both varied since the two rations were mixed by using different proportions of the base and concentrate to yield the 16 and 22 per cent levels in the finished rations. 2. Comparisons were made …

A Manual For Hog Raisers, W. J. Loeffel

Nebraska Agricultural Experiment Station: Historical Circulars

Hogs are one of Nebraska's principal sources of agricultural income. The popularity of the pig is doubtless due largely to his efficiency as a meat producer. He uses less feed to make a given gain than either the steer or the sheep. On being slaughtered, the pig dresses out a higher percentage of meat than either of the other two meat animals. Since pork is generally fatter than beef or lamb, it has a higher energy value. Pork lends itself to curing processes and, as cured meat and lard, occupies an important place in the world's commerce. Processing aids in …
