The Utilization Of Food Elements By Growing Chicks. Xi. A Comparison Of Ground Wheat And Ground Rye In Rations For Growing Chicks, C. W. Ackerson, W. E. Ham, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. The effect of replacing the shorts and bran of a standard ration by ground wheat or ground rye was studied with two lots of newly hatched chicks. 2. Comparisons were made on the basis of equal intakes of dry matter and nitrogen by all chicks. 3. The wheat-fed lot made a significantly greater gain than the rye-fed lot. 4. Several cases of curled-toe paralysis occurred in the two lots, and a tendency to cannibalism appeared in the rye-fed lot.

The Effects Of Various Concentrations Of Vitamin B1 On The Growth Of Amoeba Proteus, Walter J. Bo

Bulletin No. 323 - Migration: A Problem Of Youth In Utah, Joseph A. Geddes

UAES Bulletins

Migration has always been a problem of major importance in Utah. During early days migration to the Mormon area was known as the "gathering". The concept was unusual because it included not only the searching out of those believed to be the "honest in heart" from many nations through an extensive missionary system, but also because it possessed an "idealogy" of planned building of what was expected to be superior communities (Zions) to engage the efforts and strivings of such people when brought together. It is in the development of this idealogy--this method of building a superior culture with the …

A Survey Of The Native Rabbits Of Utah With Reference To Their Classification, Distribution, Life Histories And Ecology, Reuel G. Janson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rabbits and hares, both popularly referred to as rabbits, occupy a very prominent position in the wildlife of Utah. Over much of the state, they form the most conspicuous faunal group, and between the lowest portion of the state to above timberline on the highest mountains there are very few areas entirely devoid or their presence. There is great variation, however, in their abundance, both between localities and times. In some areas, rabbit populations often attain amazingly high numbers to the delight of sportsmen and the dismay of farmers.

A Study Of The Renal Vascular Supply In The Domestic Cat, Elizabeth Rosen

Bachelors’ Theses

Studies on the normal and abnormal vascularization of the renal vessels in the domestic cat (felis domestica) indicate the frequency of anomalies that occur, but in most of the studies it is the inferior vena cava that is most often recorded. Among the occasional references to several renal veins or arteries we have Huntington and McClure, Elmer Butler, Gaylord Bates, William Darrach, and C.H. Fortune. Yet no study seems to have been made of individuals of any particular class. A superficial observation seems to indicate a large number of cats used in the laboratory had multiple renal veins. Hence a …

A Study Of The Tolerance Of Drosophila Melanogaster For Certain Chemicals Used In An Attempt To Produce Mutations, Marian L. Collins

Bachelors’ Theses

The problem of inducing mutations holds a fascination for the scientist because no one has as yet adequately explained the cause of mutations in nature. In attempts to solve this riddle, X-rays have been used most extensively to induce mutations, but because of the recent discoveries regarding the powerful effect of chemicals and fungi produced chemical compounds upon tropical disease-carrying insects, this field of experimentation is being reinvestigated in the hope of clarifying still undefined phases of the subject.

The purpose of this experiment was to determine the capacity of different types of chemicals to produce mutations, the mutation rate …

Thrips Species Infesting Tomatoes And Other Host Plants Of These Insects In Northern Utah, Darrell R. Maddock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study has been to determine which species of thrips infest tomato plants and fruits in northern Utah, and to find out which other plants occurring in this area also serve as hosts for tomato-infesting thrips.

Because of the importance of tomato-infesting thrips to the canning industry, it was decided that more complete knowledge of the species of thrips which are found on tomatoes should be obtained. Because most thrips generally have been difficult to control, it was believed that a general knowledge of the plants on which these thrips occur would enable tomato growers to eliminate …

The External Male Genitalia Of Some Rhynchophora, Arthur F. Bruhn

Theses and Dissertations

Today there is an increasing recognition among taxonomists of the importance of consideration of the complete morphology of insects in classifying them and in arrangming them in their logical phylogenetic sequence. Regarding the Rhynohophora, with which this paper is concerned, some progress toward a more complete understanding has been made. In 1912 Sharp and Muir made a study of the male genital tube of the coleoptera in general and observed that the various specializations they noted in the forms of Rhynohophora examined would doubtless be of future significance. Tanner in 1927 made a similar important study of the female genitalia …

Mirid-Bug Injury As A Factor In Declining Alfalfa-Seed Yields, Charles J. Sorenson

Faculty Honor Lectures

During the forty or more millions of years that insects have inhabited the earth they have developed remarkable adaptations and great powers of reproduction that have enabled them to spread over most of the world and occupy all of its habitable environments. In cultivating the land and in growing crops, man has disturbed the balance in nature which formerly prevailed. By doing this he has unwittingly assisted many insect species to multiply in unprecedented numbers by providing them with more delectable food in abundance and by transporting them from place to place and from continent to continent in his migrations …

The Utilization Of Food Elements By Growing Chicks. X. A Comparison Of Open-Pollinated And Hybrid Corn In A Ration For Growing Chicks, C. W. Ackerson, W. E. Ham, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. The effect of replacing the open-pollinated corn with hybrid corn in an otherwise complete ration was studied in a growth and body analysis experiment with two lots of newly hatched chicks. 2. The pelleted rations were consumed in identical amounts by all chicks of both lots. 3. There were significant differences in the growth rate of the chicks at the end of a six-weeks feeding trial in favor of the lot fed open-pollinated corn.

Length Of Life Of Roots Of Ten Species Of Perennial Range And Pasture Grasses, J. E. Weaver, Ellen Zink

Department of Agronomy and Horticulture: Faculty Publications

It is well known that death of the tops of practically all prairie grasses occurs each fall in temperate grasslands where the soil is regularly frozen. Year after year new shoots replace the old ones in this vegetation of long- lived perennials. But as to what portion of the root system is retained and over what period of time, we are almost without information. This maintains despite the fact that much work has been done to increase our knowledge of the root systems of prairie grasses. Since the early studies of Weaver (6, 7) on their depth and lateral extent, …

Annual Increase Of Underground Materials In Three Range Grasses, J. E. Weaver, Ellen Zink

Department of Agronomy and Horticulture: Faculty Publications

Any thoughtful student who has seen the mellow, granular, fiber-filled soil of virgin midwestern prairie and the same soil that has been cropped with maize or wheat for only a decade has cause for deep concern. For the cropped soil has lost its mellowness, the granular structure of discrete crumbs has largely disappeared as has also the binding root fiber. The soil when dry is often like dust, dust that pours between the fingers and is dispersed by the wind before it reaches the ground. Throughout the Midwest soil drifting has greatly increased, and erosion by water has become accelerated …

Morphology Of A New Species Of Bat Cestode, Hymenolepis Roudabushi, And A Note On Hymenolepis Christensoni Macy, Ralph W. Macy, Robert L. Rausch

Examination of material of a species of Hymenolepis collected by Rausch from several species of bats taken near Marysville, Ohio, revealed that it was new. A series of specimens of the same species was collected in 1942 at Ames, Iowa, by Dr. Robert Roudabush. The new species, Hymenolepis roudabushi, is described.

Bulletin No. 322 - Irrigation Companies In Utah: Their Activities And Needs, Orson W. Israelsen, J. Howard Maughan, George P. South

UAES Bulletins

Utah has approximately 700 irrigation companies having more than 8,750 miles of unlined earth canals, 410 pumping plants, 1,973 diversion dams and nearly 400 storage dams which provide a storage capacity for more than 3,400,000 acre-feet of water. More than 42 million dollars is invested in irrigation works, with at least 1.5 million dollars spent annually for maintenance.

Irrigation companies have the major responsibility for safe maintenance and efficient operation of Utah's dams, canals, spillways, waste-ways, flumes, inverted siphons, head gates and lateral gates--the structures with which irrigation water is stored, diverted, and conveyed to 1.3 million acres of productive …
