Carotene Content Of Native Nebraska Grasses, I. L. Hathaway, H. P. Davis, F. D. Keim

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The carotene content of twenty-four grasses native to Nebraska were determined at approximately monthly intervals from June to November. While the carotene concentration of most of the grasses was moderately high during the growing season, it declined to a rather low point by late November. With the exception of Switchgrass, Hairy Grama, Little Bluestem and Prairie Dropseed, all of the grasses contained enough carotene to supply the needs of range cattle until late November. However, only eighteen of the grasses still contained enough carotene by the latter part of September to furnish the carotene required by dairy cows. Even as …

The Effects Of Oxygen, Carbon Dioxide, And Pressure On Growth In Chilomonas Paramecium And Tetrahymena Geleii Furgason, D.M. Pace, R.L. Ireland

Papers in Microbiology

The effects of oxygen, carbon dioxide, and pressure on animal organisms have been widely studied, but most of the investigations in this field concern chiefly the effects of extreme, especially high, atmospheric pressures on blood changes, respiration, length of life, etc., in Vertebrates.

Very few detailed observations have been made on the relation between oxygen tension or carbon dioxide tension and growth in Protozoa. The few investigations that have been carried out are concerned primarily with the effect of these gases on respiration although some observations have been made on the relation of aerobic and anaerobic conditions and growth in …

A Survey Of Fruit Production And Consumption In South Dakota, 1944, Agricultural Experiment Station, South Dakota State College

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

The importance of an adequate supply of fruit in the diet has been stressed in recent years. Nutrition and production specialists have long believed that both the production and consumption of fruit have be too low in South Dakota. Climatic and transportation problem in South Dakota, often make it difficult for some families, particularly in the western part of the state, to grow or purchase adequate supplies of fruit throughout the year. The lack of information on the quantities of fruit produced and consumed in South Dakota prompted the State Nutrition Committee to make a state wide study during 1944. …

Range Land Of America And Some Research On Its Management, Laurence A. Stoddart

Faculty Honor Lectures

Although grazing of livestock has been a practice and a profession of man almost from his beginning only recently has range management reached anything approaching a pre~ cise science. Although ' trials and errors over the years brought to light much practical methodology for assuring high production from grazing land, still it remained for the plant physiologist and ecologist to find the whys and wherefores, and to advance new methods and new thoughts which promise to increase productivity still further and at the same time maintain the great range resource.

Charcoal Rot Of Corn And Sorghum, J. E. Livingston

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In Nebraska, the charcoal rot caused considerable damage to the 1940 grain sorghum crop in the south central counties, and the following year it caused serious lodging and reduction of yield in both corn and sorghum in all sections of the state. Field observations indicated that some varieties of sorghum were damaged less than others; thus it appeared desirable to test thoroughly all varieties to determine whether any were sufficiently resistant to be recommended for field planting or to be used in a breeding program. It seemed desirable to study the influence of soil environment on infection and the development …

Studies On The Riboflavin Content Of Cheese, I. L. Hathaway, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The riboflavin concentrations of twenty-seven kinds of cheeses and cheese spreads were determined by feeding these products to rats whose body stores of riboflavin had been depleted by being fed a riboflavin-deficient diet. Fifteen experiments were made in which 1,223 rats were used. The results obtained varied from 13.5 to 1.2 micrograms of riboflavin per gram of cheese (or spread). The samples of Goat, Velveeta, Mel-0-Pure, and Liederkranz had the highest concentrations of riboflavin while the samples of Cream and Pimento Cream had the lowest concentrations.

Bulletin No. 317 - Range Lands Of Utah County And Their Utilization, L. A. Stoddart

UAES Bulletins

Utah County, comprising about 1,394,760 acres, lies in the north central part of Utah immediately west of the precipitous Wasatch Mountains. These mountains, which occupy about the eastern half of the county, vary in elevation from 4,700 feet at the bench lands to 9,000 and 10,000 feet. Extreme elevations of 12,000 feet are found on the highest peaks. The western half of the county, although broken by small mountain ranges, is much more level, lower in elevation, and more arid. Whereas the mountainous eastern parts of the county are marked by higher precipitation and, consequently by relatively dense vegetation, mostly …

Bulletin No. 316 - Marketing Fruits And Vegetables In Utah, W. Preston Thomas, George T. Blanch

UAES Bulletins

During the period from 1920 to 1941 the fruit industry in Utah and other areas or the west went through a period of adjustment. Previous to and during World War I, growers received high prices for fruit which resulted in increased production. However, following the sudden drop in prices of 1920, fruit growers had a hard time to market the large tonnage produced. Returns were low. During this period keen competition for the sale of fruits developed between individual growers and various producing areas. Although the problems of adjustment were severe in most fruit areas of the west, the marketing …

The Effect Of Adrenaline Injection On Glycogenolysis And Glycogenesis In Rat Livers, Virginia Mary Zingsheim

Bachelors’ Theses

Present day knowledge concerning the liver is derived from many sources and the accumulation of many methods of investigation. Sugar, which is needed by the body for energy, is stored in the liver as glycogen. Claude Bernard (26), an eminent physiologist, was the first to suspect that carbohydrates were stored in the liver. Faulty glycogen synthesis and hydrolysis results in one of our most widespread diseases, diabetes. Thus, many biochemists and physiologists have tried to find the mechanism of the process, and the primary and secondary facts which affect glycogenesis and glycogenolysis. Although the chemical secretions and hormones of such …

Making Permanent Mounts Of Fern Gametophytes, Gail Seeraphine Barczak

Bachelors’ Theses

One of the botanists first to grow fern gametophytes from spores whicch were sown on moist clay was Farlow (1874), a student of the famous botanist, DeBary, professor of Botany at the University of Strassburg in Germany. Farlow sowed the spores of Ptteris cretica var. albo-lineata on moist clay placed into small flower pots. Watering was accomplished from the top. There was no sterilization of the culture medium. The gametophytes of this fern were also grown under the same conditions by DeBary (1878). Steil (1919a) grew the prothalli of Ptteris sulcata and Ptteris cretica var. albo-lineata in the same manner …

Controlling The Ph Of Cultures Of Penicillium Notatum Through Its Carbon And Nitrogen Nutrition, Albert E. Dimond, George L. Peltier

Department of Plant Pathology: Faculty Publications

A survey of published material reveals relatively little information concerning the nutritional physiology of Penicillium notatum Westl. on synthetic media. Metabolism studies of P. notatum on various media have appeared to be incidental to the more pressing problem of producing penicillin quickly and in quantity. Fleming (1929) originally used a nutrient broth non-synthetic in nature. The Oxford group (Abraham et al., 1941) then adopted a modification of the so-called Czapek-Dox synthetic medium which supplies nitrogen as sodium nitrate and glucose as carbohydrate. Hobby, Meyer, and Chaffee (1942) suggested that brown sugar be substituted for glucose in this nutrient, with …

Poultry Progress: What Are Good Chickens?, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

The desire for improvement is one of the highest of human virtues. Folks everywhere want good chickens. The poultry business is a competitive enterprise, and it is imperative that we have the best stock possible for the particular job to be done. But what are good chickens? Is there confusion about the term? Perhaps we can clarify the picture by asking one or two questions.

Bulletin No. 314 - Gains Made By Cattle On Summer Range In Northern Utah, L. A. Stoddart

UAES Bulletins

The Utah Agricultural Experiment Station, in 1934, began experimental studies on the grazing of beef steers on mountainous summer range lands. Although the direct purpose of this work was to find whether supplementing phosphorus in the diet of grazing steers would increase their gains, many incidental observations proved of great interest. Among the most significant were the distribution and extent of weight gains through the summer grazing season and the effects of various factors such as weather upon the gains, causing them to vary greatly from year to year.

Nutritional Status Of Some Utah Population Groups, Almeda Perry Brown

Faculty Honor Lectures

The science of nutrition is the science of life. Though man is still ignorant of the true nature of that elusive force we call life, he has learned by means of the discovered laws of nutrition how to preserve and prolong life as well as how to add to the satisfactions of living.

The emergence of the sicence of nutrition from the maze of superstition which for centuries clouded man's thinking is a fascinating story. A story, however, that arouses a feeling of regret that for so long a time man was willing to attribute to supernatural forces all phenomena …

The Use Of Dried Whey And Blood Meal In The Raising Of Calves On Limited Amounts Of Milk, I. L. Hathaway, G. W. Trimberger, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The use of substitutes for milk in the raising of calves is always of interest to the progressive dairyman, since there are a number of circumstances in which it is advantageous to reduce the milk feeding period. Producers of market milk often desire to raise their calves on as little milk as possible in order to have more milk available for market. When the demand for milk is good, dairymen who usually market cream only may prefer to sell milk and raise their calves on starters or other milk substitutes. Dairy farmers may wish to use the skim milk generally …
