The Feeding Value Of Certain Duck Food Plants Of The Bear River Migratory Bird Refuge As Determined By Chemical Analysis, Dale Clair Christensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of bird feeding problems has become a prominent factor in wild life management. This is true especially with respect to the evaluation of recently established migratory bird refuges. In 1929 the Federal Government assumed control of a large area of land located on the Bear River Bay of Great Salt Lake for the purpose of providing a sanctuary for water fowl. Dykes were built and the areas inside these dykes flooded with fresh water from Bear River. During subsequent years aquatic and marsh plants* developed abundantly and apparently have provided satisfactory feeding and nesting grounds for migratory birds. …

Bulletin No. 277 - A Study Of Utah's Winter Range: Composition Of Forage Plants And Use Of Supplements, A. C. Esplin, J. E. Greaves, L. A. Stoddart

UAES Bulletins

Range forage provides the foundation for the maintenance ration available for most sheep wintered in Utah. The nature and amount of supplemental concentrate or roughage needed with this forage to provide an adequate and efficient ration for sheep naturally depends on the nature and amount of range forage available. Present uncertainty as to the relative merits of the various available supplements originates largely through a lack of definite knowledge as to the composition and feeding value of the various range plants that go to make up the range-forage supply on the particular range in question.

The Relation Between Health Ratings Of Seventh And Eighth Grade School Children And Their Family Social And Economic Backgrounds, Brigham City, Utah, 1935-36, Ralph Jenson Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Especially during the last century the health of school children has been a problem of deep concern. Many physical examinations have been given by numerous organizations with the intention of discovering organic disorders that might be detrimental to a child's normal social life. As a result of such study, humanity has generally come to recognize the social and economic costs of ill-health and has embarked on remedial and preventive campaigns to improve the well-being of children. Foundations have been endowed. Free clinics have been established to serve those families whose incomes prohibit them from securing medical services otherwise; county, city …

The Microflora Of Milk Drawn Aseptically From The U.S.A.C. Dairy Herd, Lewis W. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Early studies on the bacterial content of milk were made mainly to satisfy the interest of people who wished to determine the various materials that contained bacteris. Soon the value of bacterial counts, as an indication of the general conditions of production, of handling, and of the keeping qualities of milk, became evident and bacterial counts were used to obtain information concerning these problems. Numbers of bacteria in milk have been used also in the studies of the desirable and undesirable changes in milk.

In the last few years our citizenry has been made more conscious of the presence and …

The Plankton Of The Bear River Migratory Waterfowl Refuge, Utah Seasonal Distribution Of Organisms, George Piranian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the summer of 1932, an investigation of some biological, physical, and chemical conditions at the Bear River Migratory Waterfowl Refuge, Utah, was begun at the Utah State Agricultural College to determine some of the factors governing the biological productivity of brackish-water marshes. Unfortunately, lack of funds made it impossible to continue work beyond the first season.

In 1936, the Wild Life Experiment Station at the Utah State Agricultural College appropriated a fund for a cooperative project between the Station and the Department of Botany at the same institution. This project, planned to be continued by various graduate fellows over …

The Life History Of The Dewberry Fruit Worm Cacoecia Rosaceana (Harr.) In Utah, Merlin W. Allen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study has been to determine the identity and the life history of certain larvae attacking dewberry fruits and foliage in a few sections of Utah. The dewberry fruit worm as it was called until it was definitely identified the oblique-banded leaf-roller, was first observed by farmers at Granite and Butlerville in 1932. Since 1934 it has been found affecting dewberries in other parts of northern Utah.

This investigation was begun in the spring of 1935 and continued until the fall of 1936, being made possible through the Utah Agricultural Experiment Station, Department of Entomology, and with …

Bulletin No. 275 - Types Of Farming In Utah, Marion Clawson, Walter U. Fuhriman, George T. Blanch, W. Preston Thomas

UAES Bulletins

A large portion of the agriculture of Utah, outside of the desert range areas, is characteristically heterogeneous rather than homogeneous in character. Marked differences in size of farm, in crops grown, in livestock kept, in yields, and in farm organization occur within short distances. This diversity is due in large measure to differences in soil, elevation, topography, and other physical features and to climatic characteristics such as amount, kind, and distribution of precipitation and length of growing season. The physical and climatic features are the chief determinants of the amount of water potentially available for the irrigation of the crop …

Bulletin No. 274 - Influence Of Rotation And Manure On The Nitrogen, Phosphorus, And Carbon Of The Soil, J. E. Greaves, C. T. Hirst

UAES Bulletins

All agricultural plants require carbon, hydrogen, oxygen, nitrogen, calcium, potassium, magnesium, sulfur, phosphorus, iron, and probably traces of other elements for their normal growth and fruition. The growth of farm crops is dependent upon an available supply of these elements, and the extent of growth is governed by the one present and available in least quantity in proportion to the plant's needs. Of the essential elements, all plants secure two (carbon and oxygen) from the air, one (hydrogen) from the water, and the others from the soil. Most soils contain sufficient plant nutrients for normal plant production, with the exception …

The Vitamin D And Provitamin D Content Of Some Varieties Of Utah Wheat, Harold M. Nielsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cereal grains were known to be notably deficient in the anti-rachitic principle even before the discovery of vitamin D. Clinicians had associated a type of rickets of infancy, characterized by an over-weight, flabby, bowlegged condition, with a diet consisting mainly of cereals. Mellanby (1) in 1921 concluded that this type of rickets is induced by overfeeding with carbohydrates. He also showed in the same report, however, that oatmeal, although it contains less carbohydrates than the other grains tested, possesses a special tendency toward rachitogenesis.

A Preliminary Survey Of Some Of The More Important Insects Of The Cache National Forest, Theodore O. Thatcher

Biology

Studies of forest insects in America have been, in the past, principally undertaken only in cases of serious outbreaks, and little or no attention has been paid to determinations of the presence of potential pests. Especially is this true of the western United States where forest conservation has received practically no consideration other than fire control and attacks upon serious pest outbreaks, However, of late years it has taken a more important position in public planning with the Civilian Conservation Corps being utilized in reforestation and insect control programs throughout the nation. Little effort has been made to study the …
