Causative Factors And Some Consequences Of Dystocia In Two-Year-Old Heifers, Delyn Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Causative factors and some consequences of dystocia were examined in 3923 parturitions among Hereford and Angus x Hereford crossbred two-year-old heifers. Fifty percent of the parturitions required some assistance. Minor assistance was required in 34.5% of the parturitions and major assistance involving use of a calf puller, in 15.1%. Caesarean section and foetotomy were rendered in 0.3% and .05% of the cases, respectively. Abnormal presentation at birth, which included leg back, head back, backwards, hiplock and breech, was observed in only 2.9% of the births and therefore is a minor contributor to dystocia. The major causes of dystocia were not …

The Effect Of Wilt-Pruf, Antitranspirant On Reducing Water Loss Of Apple Trees, Hassan A. Nammah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The influence of different concentrations of a film-forming antitranspirant (Wilt-Pruf) on the transpiration rate of young apple trees (M106) was studied. One-year-old Mailing 106 trees were potted in 10.2 em (4 inch) metal pots. The plants were placed in a controlled environmental chamber during the study period. Sufficient reductions in water loss resulted with all concentrations of Wilt-Pruf with a 63 percent reduction at the highest concentration. Phytotoxicity was not observed though the higher concentrations imparted a sticky film to plants and they appeared to be lighter green at the end of the test. The effect of Wilt-Pruf on four-year …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to determine whether a functional relationship exists between human tissue and environmental levels of chromium and/or zinc and in individuals with maturity onset diabetes.

Three counties of Utah were selected as sites:

1. Wayne County, where a State Health Department screening had shown a 12.7 percent incidence of diabetes, and, where there is very little industry, and an assumed low level of environmental chromium and zinc

2. Utah County, where the diabetic screening had shown an 0.75 percent incidence of diabetes and where there is nearby large industry and an assumed higher level of zinc and …

Sodium And Potassium Nutrition Studies Of Halogeton Glomeratus (M. Bieb) C.A. Mey, Ali A. Alhelal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Halogeton glomeratus (M. Bieb) C.A. Mey when grown in nutrient solution, caused the solution pH to decrease very rapidly as plants increased in size, especially during the fifth week of growth. This might be attributed to hydrogen ion exchange for cations. Also, the cation uptake, especially K and Na, may exceed that of the major anions. The control of pH is effective in increasing shoot weights markedly.

In general there was no difference between plants grown at the same NaCl concentration at low and high relative humidity. An increase in plant size, shoot weights, leaf length and diameter was detected …

An Electron Microscopic Examination Of Spermiogenesis In The Recessive Sex-Linked Male-Sterile Mutant, Ms(1)10s Of Drosophila Melanogaster, Lizabeth A. Perkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Electron microscopy of the testes of mutant ms(1)10S of Drosophila melanogaster is characterized by three major defects in the tail region of the developing spermatid. One is the apparent lack of paracrystalline body formation. The second is the loss of the primary derivative as development proceeds, and the third is the breakup and incorporation of the plasma membrane and periaxonemal sheath into membranous whorls. The mutant shows different patterns of axonemal breakup depending on the stage of differentiation in which degeneration begins. Degeneration continues until only cellular debris, scattered axonemal profiles and membranous whorls are all that are seen …

Impact Of Water And Soils Having High Source-Sink Potentials On Water And Salinity Management Under Irrigation In The Upper Colorado River Basin, Lyman S. Willardson, R. J. Hanks, J. J. Jurinak

Reports

Water management in irrigation projects is one potential method for reducing downstream salinity in the Colorado River. An important contribution can be made to developing more effective irrigation water management practices for water conservation and salinity control through identification and better understanding of the soil and water interactions that result in soils behaving as salt sources or as salt sinks. The interactions identified in this study were examined to determine the effects of various management alternatives on the quality and quantity of salt in subsurface return flow from irrigation projects. A soil solution chemistry model was developed to describe the …

An Evaluation Of Heart Rate As A Measure Of Daily Metabolism In Pigeons (Columba Livia), Robert K. Flynn

Biology

A positive, linear relationship of heart rate to metabolic rate, as measured by oxygen consumption, was demonstrated in each of seven pigeons (Columba livia). The linear regression equations which describe this relationship were pooled to yield two equations from each of two trials, six weeks apart. A significant shift in the slopes of these lines occurred within the 6-week period between trials. V02 - air temperature data extrapolated to a body temperature of 40.7°C at zero metabolism and thermal conductance of -0.23. The individual regression equations were used in conjunction with average 24-hour heart rate to predict the existence metabolism …

Host Plants Of The Sugarbeet Root Maggot Tetanops Myopaeformis (Von Röder), Glenn G. Mahrt

Biology

The sugarbeet root maggot is supposedly native to North America, yet it was previously known to develop only on Beta vulgaris, a plant introduced from Europe. Various authors reported finding eggs or infested plants of lamb's quarter (Chenopodium album), redroot (Amaranthus retroflexus), prostrate pigweed (Amaranthus blitoides), black nightshade (Solanum nigrum), and curly dock (Rumex crispus). Field, greenhouse, and laboratory studies were conducted to determine the native or alternate hosts of the sugarbeet root maggot and their relative suitability as hosts. In the field, suspected hosts and related plants were surveyed and subjected to sugarbeet root maggot flies under artificial and …

Quantitation Of Formaldehyde Resulting From Oxidative Deterioration Of Unsaturated Fatty Acids, Stanley J. Andrews

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Derivatives of 3-methyl-1-2-benzothiazolinone hydrazone were formed from the oxidation products of three oxidized unsaturated fatty acids. Aeration with oxygen and heat (65C) was used as a means of accelerating deterioration of lipid samples. Formaldehyde was recovered from oxidized pure standards of oleic, linoleic and linolenic acid methyl esters, and identified using gas chromatography. Formaldehyde was also recovered from oxidized lipid extracts of mechanic ally deboned turkey meat and turkey cluster fat. Gas chromatography was used to measure concentrations of unsaturated fatty acids during the oxidation of extracted lipids. Linoleic and linolenic fatty acids significantly decreased (p < .005) in oxidized lipid extracts from turkey cluster fat stored frozen for six months.

Magnesium Deficiency And Excitability In The Rat: An Examination Of Selected Biochemical And Physiological Events Relating Magnesium Status To Behavior, Douglas Robinson Buck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of Mg status on the behavior of rats, as determined by nonspecific excitability level and audiogenic seizure susceptibility, was investigated. Also, selected biochemical and neurological mechanisms mediating the chain of events from dietary magnesium deficit to the hyperexcitability symptoms were examined. Weanling rats fed a low magnesium (10 ppm) diet for 14 days had reduced serum, cerebrospinal fluid and brain magnesium concentrations, and increased brain (Na⁺ K⁺) -ATPase activity. They exhibited increased NEL and became highly susceptible to audiogenic seizures. Through dietary manipulation and intraperitoneal and cerebral intraventricular injections, it was possible selectively to alter …

Potential For Cattle Grazing On Sheep Range In Southwest Utah, Jose Salvador Gutierrez-Garza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study was conducted on pastures grazed by sheep in late winter at the Desert Experimental Range in southwest Utah. Estimates of plant cover and herbage production were obtained in 1977 and used to examine long-term trends in the vegetation.

The nutritional value of the six most important species of the area was assessed by chemical analysis. In addition, a management strategy was developed for obtaining some utilization of the range during the spring and summer months without affecting the traditional winter use by sheep.

Long-term records (since 1937) in cover suggest a modest increase in grasses and a decrease …

Reduced Recruitment In Utah Mule Deer Relative To Winter Condition, Phillip J. Zwank

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reduced recruitment rates in Utah mule deer (Odocoilus hemionus) showed that significant losses in production were accruing during pregnancy, the neonatal period or during the first few months after birth. The primary objectives of the study were to determine the time, extent and possible causes of these losses.

Corpora luteal and fetal rates were estimated by examining the reproductive tracts of 125 carcasses collected on selected herd units in Utah and by observing the reproductive tracts of 136 female deer captured in Spanish Fork Canyon. A laparotomy was performed on each captured female to allow visual examination of the reproductive …
