Comparison Of The Influence Of 17-Hydrocortisone And 2-Methyl 9a-Fluorohydrocortisone Acetate On The Involution Of The Thymus Gland In Mice, Gerald K. Wallace

Biology

Previous studies have shown that the adrenal cortical hormones play an important part in lymphatic tissues physiology. Several authors have demonstrated alterations in blood leukocytes and decreased thymus weight following administration of extracts or purified preparations of adrenal cortical hormones. For this reason the thymus gland weight and lymphocyte response have been used as a method of determining activity of several of the corticoids.

Studies In Transmission In Ovine Vibriosis, William H. Rose

Biology

Vibrio fetus, Smith and Taylor, is the principle etiological agent of ovine infectious abortion in the United States. During the 1952 lambing season, the lamb abortions were estimated at 50,000 in Colorado, 30,000 to 40,000 in Idaho, and from 10,000 to 15,000 each in Utah and Wyoming. A conservative estimate of premature lamb losses due to V. fetus infections in the western states for this year was 100,000. In infected flocks the incidence of mortality in aborting ewes may be as high as 10 percent. Since 1952 the incidence of vibrosis among sheep has remained high.

The Effect Of Copper And Iron Salts On The Expression Of Eye Abnormalities And Melanotic Tumors In Different Stocks Of Drosophila Melanogaster, J. Howard Turner

Biology

Phenotypes in Drosophila can be altered by subjecting the developing larvae to environments containing an exess of heavy metal salts (34, 36). Such alterations, which resemble the effects of mutant genes but are not inherited, have been called phenocopies. The mechanism through which the phenocopy is produced may suggest a process through which a mutant gene influences a phenotype. In cases where such parallels are drawn, it is assumed that a mutant gene and an environmental agent have a similar effect on a particular step in an established metabolic pathway. It would seem less likely but not impossible for the …

The Biology Of The Utah Chub, Gila Atraria (Girard), Of Scofield Reservoir, Utah, Harold F. Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Utah chub is one of the most important non-game fish in Utah. It has a wide range, and occurs in every drainage in Utah. The Utah chub is not important economically as food fish nor is it of much value commercially. The sportsmen think of this species as trash and do not consider catching or consuming them. However, the Utah chub may be caught on hook and line more readily than many game species. The Utah chub in Scofield Reservoir have been caught by trolling, bait fishing and fly casting and furnish considerable sport when caught with a light …

Lethal Concentrations And Detoxification Time Of Toxaphene For Goldfish, Gambusia And Rainbow Trout, Gar W. Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the past few years the Utah Fish and Game Department, as well as the fish and game departments of other states, has been spending fisheries money for fish eradication on both lakes and streams. The Utah Fish and Game Department recently suggested to the University that research be initiated on the subject of toxaphene as a fish poison. Consequently, a better insight into conditions that exist for a given water type could be developed.

A Method For Determining Proteinase Activity, Bhupendra V. Randeria

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Enzymes play a very important role during the ripening process of the cheese. Enzymes are important in producing the body, texture, and flavor of the cheese. The breakdown of carbohydrates, fats, and proteins by added enzymes into different end products during the ripening of the cheese aids the process and may reduce time. The characteristic flavors of different varieties of cheeses are influenced by enzyme action. Some enzyme like proteinases can be used to improve the body, texture, and the flavor of the cheddar cheese. Addition of these enzymes during cheddar cheese making may shorten the ripening period. In order …

A Study Of Delayed Gas Formation In Cheddar Cheese, Mark E. Oldham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During recent years, the dairy industry has been aware of a defect in Cheddar cheese known as "late gas". This causes the mechanical openings to enlarge and become shiny. In Cottage cheese the defect exhibits itself in a general lowering of the grade and quality of the finished product.

Workers in the industry have related this defect to the starter culture, although contamination of milk, equipment and cultures may also be a source. They conclude that with a source of good quality milk and proper manufacturing procedures and efficient sanitation methods, the defect may persist.

Whichever source the defect stems …

The Use Of Protease Enzymes In The Manufacture Of Cheddar Cheese, Osamu Fujiwara

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Motor Truck Transportation Of Cattle In Utah, Loren H. Grover

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The beef cattle industry in Utah is of major importance in the economy of the state. In terms of cash receipts it is the largest single agricultural enterprise. In 1957 cash receipts from the sale of cattle and calves amounted to $38,405,000. This figure represents approximately 70 percent of cash receipts from the sale of all meat animals. It comprises 33 percent of cash receipts from the sale of livestock and livestock products and 24 percent of total cash receipts from farm marketings (2).

The production of beef animals will continue to assume a position of importance in Utah's agriculture, …

Feeding Protein, Phosphorus And Energy Supplements To Beef Cows On Utah Desert Ranges, Robert Hyrum Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many of the beef cattle in the Great Basin area are maintained part or all of the year on rangelands. Most of those going on to desert ranges for only part of the year go on during the late fall, winter, and early spring. It is estimated that 50-60 percent of the 600,000 beef cattle grazing on range lands in Utah graze on the one-fourth million acres of desert or semi-desert sometime during the year.

Artificial Pothole And Level Ditch Development As A Means Of Increasing Waterfowl Production, Charles H. Lacy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The glaciated prairie pothole country of the Midwest forms a vital segment of the most important waterfowl breeding habitat in North America. Here are hatched three-quarters of all the ducks raised in the United States. During a recent seven-year period the three-state area of Minnesota and the Dakotas produced an average of 4 to 5 million ducks annually (Janzon, 1947). This wetland region which once comprised 115,000 square miles in five states had shrunk to about 56,000 square miles by 1956 (Lynch, 1956). To maintain the present rate of waterfowl production in the face of continued destruction of habitat through …

Continuous Low Level Treatment Of Calves With Sulfabromomethazine As A Means Of Controlling Coccidiosis, Glen W. Clark

Biology

Coccidiosis is a protozoan disease. It is produced by small, one-celled organisms of the genus Eimeria. Eleven species have been reported in cattle in this country (11). At least two species, E. bovis and E. zurnii are known to be pathogenic to cattle (21).

The Typing Of Staphylococcal Isolates From Turkey Epizootics, William R. Thornley

Biology

Utah has been confronted with the problem of turkey synovitis becoming epizootic in certain areas of the state. This is a crippling disease of turkeys causing considerable loss among birds soon after they are placed on the range. Because much of the expense of brooding and rearing has already been encountered by the growers, the loss is often severe.

The Relative Influence Of The Reaction In Immune Calves On The Sexual And Asexual Stages Of Eimeria Bovis, Richard A. Heckmann

Biology

Coccidiosis has been listed as the third most important parasitic disease in cattle (13). Foster in 1949 estimated that this disease is responsible for an annual loss of ten million dollars in the cattle industry and he believed that the economic loss is at least as great as that caused by coccidiosis in poultry (17). Bovine coccidiosis kills many calves before they are six months old. Only rarely are cattle found free of coccidia (26). According to Gibbons and Baker (18) the mortality has been estimated as high as 29.3 percent in several outbreaks of bovine coccidiosis.

Immunology Of Coccidiosis Caused By Eimeria Bovis In Calves, Clyde Merle Senger

Biology

Coccidiosis is a disease which can occur in most vertebrates and certain invertebrates as a result of infection by organism classified in the Order Coccidia of the Class Sporozoa, Phylum Protozoa. Host animals become infected by ingesting the exogenous resistant stage, the oocyst (Figures 1 and 2). These oocysts may be ingested with contaminated food and water or from the bodies of other animals. In the intestine of the new host, the oocysts rupture and release a specific number of sporosoites depending upon ths genus of coccidia involved. The liberated sporesoites penetrate epithelial or other cells of the intestine and …

Some Effects Of Aldrin, Chlordane, Dieldrin And Heptachlor On The European Earwig, E. Fred Legner

Biology

During the past 15 years the European earwig (Forficula auricularia L.) has assumed the number one position as a general pest to home owners in Utah. It has spread to nearly every corner of the state where environmental conditions are suitable for its growth, and agricultural agents in certain Utah counties have received more complaints concerning earwigs than any other insect pest. This recent interest in earwigs has resulted in many suggestions and recommendations as to the most effective means of control.
