Studies On Eating Quality Of Meat: I. Palatability And Tenderness Of Lamb: Ii. Tenderness Of Turkey, Georgia C. Lauritzen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Protein was the first substance recognized as a vital part of living tissue. About 18 percent of the human body is in the form of protein, and certain protein constituents can be obtained only from dietary sources. Since meat is the chief source of protein in the normal diet, this study was aimed primarily at factors influencing quality of meat. The problem included two particular meats, lamb and turkey.

The per capita consumption of lamb in the United States is lower than that for any other meat. In 1944 in the United States 6.7 pounds of lamb were eaten per …

Thermal Degradation Of Pigments And Relative Biochemical Changes In Cherries And Apricots, K. B. Dalal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The extent and nature of biochemical changes that take place in canned fruits during storage temperatures above freezing have been reviewed and discussed by Pederson, et al. (1947). These changes include loss in nutritive value, e.g. ascorbic acid, thiamine (Brenner, et al., 1948) and deterioration of color (Tressler, et al., 1955). Bauernfeind (1953) reported that canned peaches, apricots, and sweet cherries, after a few months of storage at 70°F, frequently undergo changes such as destruction of anthocyanin and carotenoid pigments with the subsequent formation of brown colored compounds. Darkening of fruit-color eventually results in their unacceptability at …

Lactation Efficiency Of Holstein Cows As Related To Rate And Efficiency Of Growth, Charles H. Mickelsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship of quantity and quality of feed to milk production has been studied for many years. Feeding standards have been developed to systematize feeding of dairy cows according to their requirements. Recently, interest in efficiency of cows in converting feed nutrients into milk has increased.

Nitrogen Effect On Cation Exchange Capacity Of Plant Roots, Kamilia Shoukry Mohamed Shoukry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationships that exist between soil and plant are very complicated and have aroused man's curiosity for centuries. Many studies have been done in order to understand and clarify this relation. Among these is the hypothesis that plant roots exhibit cation exchange capacity (CEC) and that this is in some way responsible for differential cation uptake . The CEC of the roots was defined by Helmy (l958a) as the total cations which can be exchanged or replaced from the root surface under a given set of conditions and is usually expressed as milli-equivalents per 100 grams (me/100 g) of dry …

The Effects Of Cooking Temperature And Stage Of Doneness On Some Factors In Broiled Beef, Carmencita Salvosa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Broiling is cooking tender cuts of meat by radiant heat from hot coals, a gas flame, or an electric element. Steaks and chops for broiling are from 1 to 2 inches thick.

Broiling as a method of cooking mat is not new, but the directions for the process are the result of individual trial and error testing and are often in conflict. Current interest in indoor and outdoor broiling, particularly in Western United States, emphasizes the need for better information. There is no measuring device for surface heat during broiling and thus little research on the relationship of surface temperature, …

A Nutritional Survey Of Sweet Cherry Orchards In Utah, M. Dale Christensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The sweet cherry crop has always been the number one fruit crop in Utah until the last three or four years when it shifted to second place due to severe spring frosts. However, the outlook for its continued success is still very good. Even though there are drawbacks such as virus infestations, spring frosts, nutritional disorders, cracking, doubling, and bird injury, new plantings are being made each year in each of the important fruit producing counties. Utah is also important in the national production of sweet cherries and is presently sixth in the nation.

A nutritional survey of sweet cheries …

Factors Influencing Elk Distribution On Willow Creek Summer Range, Utah, Duane Eldro Jeffery

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is aimed at gaining a better understanding of the factors responsible for the distribution of elk on summer range, and an analysis of characteristics of preferred habitat. Such knowledge should prove of value in elk management, both in better managing elk herds themselves, and in coordinating their needs with those of other land uses.

The Respiratory Chain Involved In Oxidative Phosphorylation On Higher Plants In Relation To Carbon Dioxide-Bicarbonate Inhibition, Wan-Jean Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Increased concentrations of CO₂ with the accompanying high bicarbonate level in the culture medium have been reported to have a depressing effect in certain plant species on growth (34), respiration (23, 33), oxidative phosphorylation (9), mineral nutrient absorption (17), certain enzymatic reactions (4, 22, 27), accumulation of organic and amino acids (11), and protein synthesis (16). Since accumulation of organic acids occurs in lime-induced chlorotic tissue together with a depression in the respiration of plant tissue, an effect on the energy transfer mechanism of such plants is suspected. Inhibition of electron transfer from the substrate level could result in …

Infrared Spectroscopy As Applied To The Study Of Biochemical Changes Induced By Tobacco Mosaic Virus In Leaf Cells, Banavara Krishnappa Chandrasekhar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The biochemical reactions occurring during the early stages in the infection cycle of a plant virus are still unknown. Many studies involving bacteriophage and animal viruses that have been made in recent years have provided evidence of the nature of virus infection, but these have not been of much value in understanding the nature of plant viruses. Infrared spectroscopy applied to the study of viral infection processes by Chochran and his co-workers (1960, 1962) have given some clues about the nature of biochemical changes taking place in the leaf tissues as a result of infection with cucumber mosaic virus and …

Bear Lake And Its Future, William F. Sigler

Faculty Honor Lectures

Even in such a wide-ranging and eternally changing field as biology, a few statements about certain aspects can be made with a minimum likelihood of their being refuted. In this class are the following: No two lakes are identical. Any given lake is simultaneously many things to many people. A lake is never static. The influence of a lake reaches far beyond its shores.

Bear Lake, Utah-Idaho, can be used to good advantage to exemplify the truth of these statements. It defies meaningful comparison with other lakes unless a mass of detailed statistics is employed. To the fisherman and water …

Selected Insecticides In The Control Of Invertebrates Possibly Associated With Avian Botulism, J. Larry Haddock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Avian botulism or ''western duck sickness" has long been a major problem on duck marshes in the western part of the United States. This has been demonstrated to result from the ingestion of products of metabolism of bacterial cells of Clostridium botulinum type C. These products when ingested by waterfowl act as neurotoxins (Coburn, 1942). Studies have shown that many animal tissues are readily utilized as culture media by Cl. botulinum type C (Bell et al., 1955).

Since 1955 investigations have indicated a close relation between the occurrence of avian botulism and invertebrate population levels. It is thought that when …

The Effects Of Radium On Certain Goldfish Blood Constituents And Organs, D. Wayne Linn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Background radioactivity from radium has long existed in ground and surface waters of the United States, but in the last 15 years radium has become a consequential unnatural contaminant of waters (Coulomb, 1955; Rone, 1952; Schlundt, 1910; Scott and Barker, 1956; Scott, 1961; and Tsivoglou et al., 1958). The onset of the atomic age initiated the increased processing of uranium ore for its uranium content. Radium is a daughter product and a by-product of uranium ore and its purification (Glasstone, 1958; and Tsivoglou et al., 1958). The uranium refinery wastes are released into streams in which all forms of aquatic …

Food Availability And Selective Utilization By Juvenile Mallards (Anas Platyrhynchos Platyrhynchos L.) On The Bear River Migratory Bird Refuge, Utah, Nicholas J. Chura

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This investigation was devoted to a study of food availability and the selective utilization by juvenile mallards (Anas platyrhynchos platyrhynchos L.) from hatching through the flight stage. Such information furnishes basic knowledge which may be used for determining the effects of chemical poisons on these organisms, how breeding ground habitats could be manipulated for their most efficient use by duckling species, what nutrients occur in natural duckling foods, and the digestibility of these items. The Bear River Migratory Bird Refuge, Utah, was used as the study area during the waterfowl breeding seasons of 1959, 1960, and 1961. Mallard ducklings …

Biochemical Studies On The Effect Of Fluoride On Higher Plants, Shang-Fa Yang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluoride occurs naturally in plants, but its presence has attracted attention primarily in certain industrial areas where concentrations are elevated above normal by accumulation from the atmosphere. Certain plant species have been observed to be injured as a result of accumulation of excessive fluoride from the atmosphere. The general symptoms of fluoride injury are necrotic lesions and burning which appear first in the leaf tips and margins.

The Effect Of Feeding Fluoride On Some Enzymes Of Bovine Tissues, Prasertsri Sitachitt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fluorides are usually found in nature as constituents of soils, water, and the tissues of animals. Fluorite or fluorspar (CaF₂), cryolite (Na₃AlF₆), apatite (3 Ca₃ (PO₄)₂ CaF₂) and sedimentary phosphate rocks are among the principle minerals containing fluorides found in nature. Traces of fluorides also occur in domestic water supplies in nature and also by induction in vegetation and animal feeds. From 0.5 ppm to 1.5 ppm of fluorides in drinking water is the range found to be beneficial in reducing the incidence of tooth decay in man. …

Influence Of Age On Milk Production Of Holstein Cows In Utah, Marvin R. Green

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Production of dairy cows is influenced by many factors, among which are: genetics, nutrition, management, disease and age. Most of these factors can be modified to maintain a high level of production. Age, however, is beyond the influence of mankind; therefore, it is important to understand the effect of age on milk and butter-fat production.

Quality Evaluation Of Certain Fruit Jellies And Syrups Prepared With Sucrose, Sorbitol, And Synthetic Sweeteners, Sandra Louise Day

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Body weight is fast becoming the major health problem in the United States. Recent estimates of the number of weight conscious people in the United States are now up to 75 million. One year ago the estimate of overweight individuals was 60 million Americans who were overweight or should be concerned about watching their weight. There are also two million known diabetics who must control their disease and body weight by a restricted caloric intake.

An Evaluation Of Antibiotics Upon Selected Dairy Organisms, Roy Brog

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was designed to answer a three-fold purpose. Primarily, it has endeavored to measure the inhibitory effect of three antibiotics (potassium pencillin, dihydrostreptomycin, and oxytetracycline) on lactic acid producing organisms. The lactic acid-producing organisms include Streptococcus lactis, Streptococcus thermophilis, and Lactobacillus bulgaricus.

The determination of an effective dose of a given antibiotic which will inhibit 50 percent of the lactic acid-producing organism (E.D.₅₀) will be established. A 50 percent cut in acid development will certainly lead to an inferior product.

The secondary purpose has related to the detection of inhibitory substances (antibiotics) in milk. What is …

A Study Of The Use Of The Hydrogen Peroxide-Catalase Treatment Of Milk In The Manufacture Of A Reduced Fat, Cheddar-Like Cheese, Lamar John Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nutritionists, the medical profession, and the public in general have become increasingly interested in low fat food products. Cheddar cheese, as it is now made, has a high caloric value and therefore may be discriminated against in some diets. The production of a reduced fat cheddar-like cheese would be of importance to the cheese industry by providing a reduced fat, high protein product.

The chemical nature of the casein furnishes the foundation for the body and texture in cheese. The body and texture of typical cheddar cheese is influenced principally by its fat and moisture content.

A Genetic Investigation Of A Yellow Plant Color Characteristic In Winter Wheat, John Oscar Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective in wheat hybridization primarily is to obtain new varieties which are of a greater agronomic value than existing varieties. Frequently, however, crosses which obviously will not produce superior commercial types are made and studied in order to obtain genetic information which may be useful to the breeder. This latter phase of breeding, i.e., the accumulation of genetic information, provides the basis for this study.

Experiments On The Origin And Nature Of A Zinc Deficiency Of Field Beans On A Portneuf Soil As Determined By The Application Of Zinc 65, Edgar Dale De Remer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In a few instances an agricultural problem lend itself well to research into some of the more basic aspects of a problem as well as to research to determine the exact nature of the problem ad to prescribe a cure. Such a problem was found by the author to exist on a soil of the Twin Falls, Idaho area. Besides making an attempt to ascertain the exact nature of the problem, an experiment was set up in an attempt to understand more about the mechanism responsible for the problem.

Effect Of Sweeteners On The Acceptability Of Selected Processed Fruits, Richard Lee Mclaughlin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Effect Of Chelates On Phosphorus Availability And Mobility, Salah Ahmed Tahoun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil-phosphorus relations and plant-phosphorus relations have attracted the interest of many investigators since Liebig introduced his famous theory about the importance of the mineral matters to the plant in 1840. It was soon realized that phosphorus nutrition was a problem not easily solved for two reasons. 1. The added phosphorus fertilizers, soon after soil application are converted by some reactions in the soil to complex compounds far less soluble, consequently less available to the plant. Conclusions about this process led to controversial debates until it was discovered that a general statement covering all soils was impossible since the reactions involved …

The Effect Of Range Condition Upon The Production, Nutritive Intake And Digestibility Of Desert Range Forage In Southwestern Utah, J. Kent Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The 65 million acres of winter range in the Intermountain region furnish forage for about five million sheep and four million cattle each winter for approximately six months. These arid ranges are well suited for winter grazing, and are of paramount importance to the livestock industry. Many of these ranges were fully stocked by 1900 and as livestock continued to increase, many winter ranges were seriously over-grazed (Hutchings and Stewart, 1953). Today many of these ranges remain in a deteriorated condition. Forage production has decreased and desirable plants have been replaced by less desirable species.

Little is known about the …
