Relative Activity Of Sulfaquinoxaline, Regasul, And Parabis In The Control And Prevention Of Coccidiosis In Young Chicks, Eldon R. Child

Biology

Coccidiosis is one of the most common and most serious infectious diseases of poultry. It is a widely studied disease and a vast amount of information has been accumulated, but its vicious attacks on poultry flocks have not been eliminated. Cecal coccidiosis, caused by the parasite Eimeria tenella, is of extreme importance in young chicks. It is considered responsible for the loss of about ten per cent of all chicks hatched in the United States (1); the economic loss in poultry from all species of coccidia is estimated to amount to about 10 million dollars annually (2). In areas …

Hive And Field Mortality Of Honey Bees In Northern Utah Due To Effects Of Certain Ecological And Chemical Factors, Shih Chun Ma

Biology

The honey bee is the most important pollinating insect in Utah, because various important crops such as fruits, legumes, and vegetable seed crops depend chiefly on it for pollination. In the past, honey bees have suffered repeated severe death losses through contact with arsenic and other agricultural chemicals. Recently the newer insecticides, such as DDT, chlordane, parathion, benzene hexachloride, lindane, toxaphone, and several kinds of miticides have further complicated the problem of bee survival. In addition, natural enemies such as predators and parasites and some unfavorable environmental conditions, including unfavorable temperature and humidity, wind, storm, and other changeable weather conditions, …

Actinomycetes Of Virgin Utah Soils With Special Reference To Antagonisms, Paul H. Krumperman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of actinomycetes in the soils was generally overlooked until about 1913. The investigators Hiltner and Stormer and Beijerinck began systemtaic study of their occurrence and role in soil fertility. The work done by these men and others since 1913 has proved actinomycetes to occur abundantly in most soils of the world. This work done by these men and others since 1913 has proved actinomycetes to occur abundantly in most soils of the world. This work has also proved the function of these organisms to be that of decomposing highly resistant materials such as humus and complex polysaccharide compounds. …

Some Factors Which May Influence Survival Of Game Farm-Reared Pheasants After Release Into The Wild, Taylor F. Cottle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was undertaken in an attempt to determine some of the factors which may influence the survival of Utah game farm-reared pheasants following their release into the wild. The survival of these birds is below the desired level after they are released, as is indicated by the low percentage taken by the sportsmen during the hunting season. In recent years the return from released game farm-reared pheasants is about 7 to 8 percent.¹ Consequently, if survival rate of these birds could be increased, more birds would be available to supplement the wild stock. Also, an increase in the …

A Study Of The Courses That The Physical Education Major Professional Graduates, From 1939 To 1947, Inclusive, Used To Fill Their Group Requirements At The Utah State Agricultural College, Ted Heath

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Prior to the year 1913, there had been some schools at the Utah State Agricultural College that had had biological science, exact science, language and arts, and social science groups for the graduates to fill requirements in before they could graduate from these particular schools.

However, it was not until the year 1913 that all of the schools, with the exception of the engineering school, were required to make the students meet these basic group requirements.

Leafhoppers (Cicadellidae) Associated With The Stone Fruit Orchards Of Northern Utah, Mervin W. Nielson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Virus diseases of stone fruit orchards have existed in Utah for more than a quarter of a century and are seriously diminishing the peach and cherry fruit production. Western X of peach, rusty mottle of cherry, wilt and decline of cherry, and little cherry constitute the most economically important stone fruit virus diseases in Utah. Many orchards, particularly in Davis County, have 50 to 83 percent of the trees infected with one or more of the yellow-red viroses. Surveys have shown that the diseases are spreading from 3 to 5 percent each year. It is believed that certain insects are …

Harvest Of Wild And Stocked Fish From The Logan River Drainage, Louis S. Pechacek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Logan River, one of Utah's better trout streams, has carried more than its share of the increased fishing pressure of the past few years. Careful management of the drainage by the U.S. Forest Service has kept the Logan River free of serious water fluctuations and relatively unpolluted by silt and wastes. The only noticeable fluctuations in the stream is the annual runoff cycle which usually reaches its peak in May. This alone has contributed greatly to the ability of the river to withstand the increased fishing pressure which it has done quite well. The increase in fishing pressure can …

A Survey Of Plant Parasitic And Associated Species Of Nematodes In The Carrot Producing Area Of Cedar Valley, Iron County, Utah, Paul R. Fitzgerald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant parasitic nematodes have long been known to cause extensive crop losses through reduced yields, shortened productive life, or lowered value of produce. The rood knot nematode, Heterodera marioni, is cosmopolitan. It destroys crops and causes economic losses equal to those of any other plant parasitic species. in 1948 this nematode caused an estimated loss to the carrot raising industry in Iron County, Utah of approximately $15,000. No estimates for the years prior to 1948 are available; however, reports of the county agent (14) for Iron County show that carrot production in the Cedar Valley is decreasing, and is …

Levels Of Lygus Infestation And Stages Of Plant Development As Related To Alfalfa-Seed Production, B. Austin Haws

Biology

Alfalfa-seed production was one of Utah's most important and lucrative forage crops 24 years ago. Statistical reports compiled by Professor C. J. Sorenson, Research Professor of Etomology at Utah State Agricultural College (30), show that in 1925 the 69,000 acres of alfalfa seed raised in Utah yielded an average of 6.37 bushels of seed per acre. Utah's alfalfa-seed yield in 1925 was 42 percent of the total alfalfa seed grown in the United States. This bumper crop brought an income of approximately $4,433,022 to Utah seed producers that year.

A Cultural And Transmission Study Of Staphylococci In Turkeys, Royal Anderson Bagley

Biology

The turkey industry is one of the largest agricultural pursuits of the state of Utah. Synovitis is one of the most costly diseases in this industry. Surveys in limited areas in 1944 showed 39% of the flocks were afflicted, with mortality varying from 5% to 20%. In 1947 and 1948 there was widespread occurence of the disease throughout the state; the disease usually occurred between the 9th to the 12th week of age and persisted until marketing. Synovitis has caused considerable economic loss to the grower.

Alfalfa As A Source Of Carotene In The Diet Of Chicks, James Joseph O'Toole

Biology

The value of carotene as a precursor of vitamin A in the animal body was shown conclusively by the work of Moore (20). Rats which had been depleted of vitamin A and fed carotene following the depletion period, showed vitamin A absorption maxima in liver tissue when assayed spectrophotometrically. Depleted rats fed on the carotene-free diet showed no vitamin A absorption spectra. Capper, McKibben and Prentice (6) showed that chickens were also able to convert carotene into vitamin A.

The Biology Of Nabis Alternatus Parshley (Hemiptera, Heteroptera) And Its Predacious Relationship To Some Alfalfa Pests In Cache County, Utah, Earl John Taylor

Biology

Nabis alternatus Parshley is a hemipterous insect belonging to the family Nabidae. It is commonly found in alfalfa fields, among small grains, native grasses, and on rangeland throughout Utah. A need for life cycle studies has existed for species of this family. This becomes evident as one reads the fragmentary reports of their habits as insect predators.
