The Physiological Effects Of Feeding Systox Residues To Cows And Calves, Le Grande C. Ellis

Biology

Since World War II there has been an increase in the number of new insecticides on the market. One group, the organic phosphate insecticides which were developed during the war by Schrader (2, 20), is effective in controlling plant-feeding insects (19). Soon after these new insecticides were introduced, reports indicated that residues remained on forage crops after harvest which could be directly harmful to animals consuming them, or indirectly to man. It has been shown by Biddulph et al. (5) and Sheppard et al. (31) that DDT residues appear in the milk of cows eating DDT treated alfalfa. …

Fluctuations In Size And Concentration Of Tritrichomonas Foetus In Preputial Samples, George A. Jeffs

Biology

It has been established that Tritrichomonas foetus is an important organism in causing abortion and infertility in cattle. The disease produced by this flagellate results in an annual loss of over one million dollars in the United States alone. The importance of the disease warrants further investigation of this organism. The investigation was undertaken in order to obtain information concerning fluctuations in size of Tritrichomonas foetus, concentration of the organism in preputial samples, and the pH of the preputial fluid in which the parasite occurs; and to observe any possible relationship between these.

The Development Of A Practical Method For The Histological Preparation Of Adult Mammalian Bone, John F. Noble

Biology

Histological demonstration of bone has long presented a special and most difficult problem in histopathological laboratories. Many and varied techniques are described in the literature, but most of them concern only special phases of the total process. Also, many techniques which are applicable to the processing of small and yound animal bones are not suitable to routine processing of larger or adult mammalian bones.

The Airplane In Unit Sampling Of Mule Deer Populations In Harding County, South Dakota, Karl B. Kuhlmann

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The prairie deer region of South Dakota extends west from the Missouri River to the Black Hills. The region borders the states of Nebraska, Wyoming, Montana, and North Dakota, and is approximately 40,000 square miles in extent. Biologists believe that present deer numbers on these prairies are similar to those of pre-homestead days. The present large numbers of deer in certain counties have given many prairie ranchers and farmers cause for concern. The region's first deer season (bucks only) in 1952 resulted from earlier increases in mule and whitetail herds. After a closed season in 1953, a hunter's choice of …

Marketing Sheep And Lambs In Utah, 1954-55, Lloyd I. Holmes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The sheep industry of Utah began about the middle of the nineteenth century when the Mormon pioneers came to Utah. The first sheep in Utah were of Merino breeding, kept primarily for wool production. These breeds were decendants of the early Merino sheep from Spain and were probably introduced into this country by Spanish explorers. Sheep are produced to provide food and fiber in Utah. Utah's climate, topography, and natural vegetation are conducive to sheep production. Sheep do well in semi-arid climates and can economically harvest the natural vegetation on land not suited to crop production. Utah has large acreages …

Seasonal Distribution Of Mosquitoes In A Mile-Square Area West Of Logan, Utah, Takeshi Miura

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mosquitoes are one of the most important groups of insects, because of their blood-sucking habit and their ability to transmit a number of serious diseases, such as malaria, yellow fever, dengue, encephalitis, and filiariasis.

The most important mosquito-borne disease in Utah is probably equine encephalomyelitis, which is a serious disease in man, horses, and mules. According to Spendlove and others (1953), this disease occurs every year in Utah:

Cases among horses usually are scattered, but severe horse epidemics in past years have destroyed hundreds of animals. Since this disease in humans is difficult to distinguish from other similar diseases, such …

The Effect Of Sucrose Feeding On Phosphorus Content, Protein Content, And Color Of Turkey Livers And Muscles, Mary Tai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

All carbohydrates metabolized in the body must first be phosphorylated, As a result of Lundgaard's (1930 ) and Lohmann's (1934) discoveries, the focal interest of muscle biochemistry has passed from the carbohydrate molecules to the phosphorus compounds, For glucose, the first reaction is the formation of a phosphate ester, glucose-6- phosphate, D. M. Needham (1938) found that ATP acts as a phosphorus donor, Glucose-6-phosphate may be transformed into glucose-1-phosphate or into fructose-6-phosphate. In liver, it may be hydrolized back to free glucose and inorganic phosphorus, Bate-Smith (1948) indicated that the free phosphate must be present before any breakdown of glycogen …

Root Yields, Sucrose, And Glutamic Acid Content Of Sugar Beets As Influenced By Soil Moisture, Nitrogen Fertilization, Variety, And Harvest Date, Donald G. Woolley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The United States produces about 1.8 million tons of sugar annually. Approximately 75 per cent of this production is derived from sugar beets. The importance of the sugar beet crop in national and world economy is justification for research effort as a means to more economical production.

It is desirable that sugar beet processing be carried out in the most efficient manner. More effective utilization of the sugar beet and its by-products will add stability to the sugar beet industry.

For the past 170 years, since Achard found that sugar could be used for human consumption and that pulp might …

An Economic Analysis Of Merchandising Fluid Milk In Utah, E. Boyd Wennergren

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The basic problem confronting the dairy industry today is one of utilizing its total fluid milk production. During recent years the industry has witnessed a general decrease in per capita consumption of dairy products while per capita production has remained fairly constant and in amounts approximating the average for the past 16 years (Table 2 ). As a result the dairy industry has produced a surplus of fluid milk and manufactured dairy products. The Federal Government, under its price support program, has been the ultimate recipient of these surpluses and now possesses huge warehouse stocks. The cost to the Federal …

The numerous influences which are so greatly changing rural life in America are having their effect upon the farm shopwork which farmers perform. New farm machines and tools are being introduced and used, causing the farmer to learn new operations and to acquire new skills in the maintenance, repair and use of this equipment. The farm shop is becoming an essential part of every farm. In order to carry on the farming business more economically, and thereby meet competition which is necessary in present day farming, the farmer must know how to properly use his farm mechanics needs to the …

Non-Return Conception Rate Of Artificially Inseminated Cows As Affected By Dilution Rate, Grade, Bull Source, And Age Of Semen Shipped By A Utah Artificial Breeding Association, William Lloyd Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Artificial insemination of dairy cattle has become a major part of the dairy industry during the past 15 years. There has been a steady increase in the number of cows serviced each year since the first artificial breeding association was organized in the United States in 1938. In 1952 there were 4,238,245 cows bred artificially. In 1953 there were 4,845,222 and in 1955, artificially bred cows numbered 5,250,000.

A History Of The Rambouillet Breed Of Sheep In Utah, Edwin M. G. Seely

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The domestic sheep in the flocks in the state of Utah all trace their origins back to Europe. Between the sixteenth century and the present, sheep have made at least six different journeys from the old world to America and have fused their blood in the formation of the sheep industry of Utah. Each of these movements has a dramatic and interesting story to be told, but the trek of the Rambouillet is perhaps the most fascinating of all. The journey began in Spain, when by sea and by land the hardy fine-wool Spanish Merino made its way into France …

The Political Process, Milton R. Merrill

Faculty Honor Lectures

The a priori basis on which this discussion rests is that individual human freedom is desirable. The defense of this thesis is not extensive nor profound-it is rather elementary and personal. There is a further assumption, for which limited historical argument is made, that freedom, the sine qua non of political life, is best achieved and cherished in the atmosphere of parliamentary democracy. There is recognition that such freedom is limited and controlled, but there is full acceptance that in degree it does and should exist.

The argument then proceeds to the analysis of the essential element in a democratic …

Some Effects Of Inorganic Fluoride On Plants, Animals, And Man, Delbert A. Greenwood

Faculty Honor Lectures

~~~ in the compounds of fluorine may be traced to one or more of the following factors: ( 1) the consumption of a drinking water containing one part per million of fluorine as a soluble flouride during the period of calcification and eruption of the teeth causes a reduction in the incidence of tooth decay; however, an intake of drinking water containing more than two parts per million of fluorine causes dental fluorosis of varying degrees in man and certain animals; (2) a continuous intake of excessive amounts of fluorine as mineral supplement, in contaminated forage, or the grazing of …

Bulletin No. 382 - Grass-Legume Mixtures For Irrigated Pastures For Dairy Cows, George Q. Bateman, Wesley Keller

UAES Bulletins

Pastures have been important in the agricultural economy of the Intermountain Region. But as long as nearby valley bottom or other land not well suited for cultivation was available, the pressure for better irrigated pastures remained secondary to that for improved cash crops.
Only in recent years have dairymen generally realized that a productive herd, coupled with proper management, could make a good pasture a highly profitable crop. Bateman and Packer pointed out in 1945 this concept of pastures. Bateman et al. using newer mixtures strikingly verified the concept in 1949 and 1954. The growing awareness of the value …

Bulletin No. 383 - Cooperative Nutritional Status Studies In The Western Region: I. Nutrient Intake, Ethelwyn B. Wilcox, Helen L. Gillum, Margaret M. Hard

UAES Bulletins

In 1947, a concerted study of the nutritional status of selected population groups was initiated in the western region of the United States. Previous dietary surveys had indicated that substantial portions of the country's population were consuming lower than recommended levels of essential nutrients. Deficiency diseases that may have nutritional background, such as dental caries, anemia, and rickets, existed. Investigators reported subclinical signs of malnutrition in several areas. Few studies had been made in the West, although reports of high incidence of dental caries and suspected undernutrition had come from several western states. The regional committee thought it evident that …

Bulletin No. 384 - Virus And Viruslike Diseases Of Stone Fruits In Utah: A Handbook For Their Identification And Control, B. L. Richards, L. C. Cochran

UAES Bulletins

Intensive research over the last 20 years has shown that many of the previously unexplained and seemingly mysterious disorders of stone fruit trees in Utah are infectious diseases caused by viruses. Others were shown to be the result of noninfectious genetic abnormalities or of adverse chemical and physical factors in the environment of the plant. The purpose of this handbook is to help orchardists and others recognize these diseases and disorders and understand better their etiology or cause. The handbook will also bring together basic information which will aid in their control.
