Bulletin No. 377 - Performance Testing Studies With Beef Cattle, James A. Bennett, Doyle J. Matthews

UAES Bulletins

The goal in beef cattle breeding is the production of animals that make rapid and efficient gains and have desirable conformation. Performance testing has recently been advanced as a means of identifying individuals possessing superior productive qualities and as a means of evaluating sires for transmitting these qualities to their offspring. This report gives the results of performance tests conducted with Hereford and Shorthorn calves fed over a constant time period as well as the results of a supplemental study undertaken to gain information that might add refinement to the evaluation of gains in beef cattle.

A Study Of Spermatogenesis In The Charales, Robert Korn

Bachelors’ Theses

Investigations on the nature of the antherozoid, or male gamete, in the Archegoniates has been of great cytological interest to numerous workers. An apparent consistency of certain characteristics in the antherozoids of the Bryophytes and the Pteridophytes has, also, undoubtably been of value in determining phylogenic relationships.

A Study Of The Families Of Utah Hemiptera, Gerald L. Nielsen

Theses and Dissertations

This study determines the number of families of Hemiptera found in the state and has a key for their classification. The characteristics and general distributions of each family are given, along with specific examples of the most common and economically important bugs. Important references are given for each family of work done to date. It was found that there have been twenty-eight families of Hemiptera collected in Utah, some of which are well represented in numbers of genera, species, and individuals, while others are represented by a single species and collected in only one or two places in the state.

An Ecological And Distributional Study Of Small Mammals Of Cedar Valley, Utah County, Utah, Loraine Woodbury

Theses and Dissertations

This paper deals with the ecology and distribution of small mammals in the following plant communities of Cedar Valley, Utah: juniper, greasewood, grass-rabbitbrush, and shadscale. Study periods were in August 1950 and 1951, October 1951, and April 1952 with each community studied 1,440 trap-nights. A combination of the Calhoun ''B" and transect method was employed; plant species and densities were taken and soil samples were checked for moisture content, total soluble salts and mechanical analysis. In the communities studied Dipodomys ordii utahensis (Merriam) is found in greatest abundance on sandy soil and Perognathus parvus olivaceus (Merriam) is found in greater …

Meet Music, Marvel Labrie

SDSU Extension Circulars

"Confidentially, this long-haired stuff is not for me. I don't really know a thing about music, and I can't carry a tune in a bushel basket." With this pessimistic statement, many of us close the door to a whole new world of enjoyment. It does seem confusing when we hear people conversing in longhandled terms about symphonies, sonatas, oratorios, writing styles, and the like. Immediately, we become frightened by their apparent knowledge of music. Don't be misled by that big talk, which may even be done just to impress you. Knowledge of those terms doesn't mean that they enjoy music …

The Use Of Lactic Acid In The Manufacture Of Cheddar Cheese From Milk Containing An Antibiotic, Elmer George Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The manufacture of cheddar cheese is greatly dependent on bacterial growth for acid production. The quality of cheese depends upon the type and extent of microbial activity.

An important function of the lactic fermenting bacteria is the production of acid resulting from cellular metabolism. If little or no acid is production of acid resulting from cellular metabolism. If little or no acid is produced the resulting cheese will have an inferior body, flavor, and texture and may even cause the cheese to be used as grinders.

The Biology And Seasonal Distribution Of Eucalliphora Lilaea (Walker) In Cache County, Utah, Robert P. Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The association of: flies with man has been recorded through many centuries. In nearly all of these records the association is one of discord rather than harmony. In the Book of Exodus, 8:24, in the King James version of the Old Testament, we can read, "...and there came grievous swarms of flies into the house of Pharaoh, and into his servants' houses; and in all the land of Egypt the land was corrupted by reason of the swarms of flies." Centuries later the "grievous swarms of flies" 'were associated with a particular disease by Mercurialis. In 1577 he expressed the …

Survey And Evaluation Of Big Game Exclosures In Utah, Stanford Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An "exclosure" is defined by Daubenmore (1940) as an experimental area which is protected from the activities of a particular class of animals by a barrier such as a fence or screen thereby controlling a single factor of environment, namely, the animal influence.

Several different types of exclosures are employed by the land management agencies in Utah. Small portable "paddocks" a few feet square are extensively used to gauge seasonal grazing pressure by livestock. Permanently fenced areas, ranging up to many acres in size, serve to demonstrate the effects of livestock use on the range. Another modification is the "big …

Evaluation Of Stream Bottom Fauna Sampling Techniques As Used In The Logan River, Donald C. Hales

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the square-foot bottom sampler was described by Surber (1937) it has been the principle instrument used for quantitative studies of the bottom fauna in riffle areas of streams. However, little has been written concerning the actual number of square-foot samples necessary to describe stream bottom fauna in terms of the number or volume of organisms.

A Study Of Aquatic Insects Of Logan River, Utah, Daood Salman Mutlag

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Factors In The Development And Restoration Of Waterfowl Habitat At Ogden Bay Refuge Weber County, Utah, Noland F. Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Millions of acres of marshland have been destroyed by the industrial and agricultural development of this continent. Drainage, water diversion, land leveling, and some other factors which destroyed waterfowl habitat were in most instances essential steps in man's progress; but water pollution, unwise drainage, and other soil and water abuses were tragic and unessential steps in our history of land exploitation that have destroyed vast acreages of habitat. The future of waterfowl on this continent hinges upon the success of restoration or new marsh development to replace this destroyed habitat.

Effects On Urinary Metabolites Of Rats Fed Various Edible Fats, Cleve R. Winkel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For many years, substitutes for butterfat have been the subject of much controversy. Their acceptance as being nutritionally equal to butterfat has often been question. The importance of this problem lies primarily in its economic and nutritional significance.

A recent study of public attitudes toward dairy products conducted by Alfred Politz Research, Inc. for the American Dairy Association, shows that 48.4 per cent of the population believed that butter is a more nutritions food than oleomargarine. Only 6 per cent thought that oleomargarine is more nutritious while 27.2 per cent believed they are about the same. The remainder, 18.4 per …

Lactation Curves Of Holstein Cows As Influenced By Age, Gestation, And Season Of Freshening, George Edward Patterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lactation curves of dairy cows have been studied by dairy scientists for many years. The effects of various hereditary end non-hereditary influences on the lactation curve have been observed. Factors have been developed to standardize production to a common basis, correcting for differences in age, length of lactation, milking per day, gestation and environment.

Phenotypic Variations Of Kochia Scoparia, Kenneth Malcolm Benson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Kochia scoparia (L.) Schrad. has had limited use as a forage crop during the past fifteen years in parts of the western United States, Canada, and Argentina. Erickson and Moxon (1947) reported kochia* to be a good emergency feed for sheep and cattle during dry years in South Dakota. Salguero (1946) said that this species could be utilized in Argentina as silage or pasturage if harvested before flowering. Bell, et al. (1952) in Saskatoon, Canada studied this species in a comparison with other introduced plants and reported that it seemed to have desirable nutrient characteristics for livestock roughage. Plummer …

Determination Of Digestibility Of Lignin By Mule Deer, Robert B. Turner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The conflicting problems involving the herds of mule deer (Odocoileus hemionus) are of major interest throughout Utah. Individuals who are affected the most are sportsmen, ranchers, fruitgrowers, sanitation engineers, home owners, federal administrators, and big game managers. Mainly, the problems arise as a result of insufficient forage, especially on the winter range. Here, factors such as increased deer numbers, decreased range productivity, severe winters, and expanded agricultural activity make more acute the problem of a naturally critical season.

Restoration of forage by artificial measures may be necessary as a management solution for certain areas. Range rehabilitation, rather than …

A Study Of The Winter Foraging Habits Of Mule Deer In Enclosures In Northern Utah With A Test Of The Half-And-Half Sampling Technique, Donald R. Flook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mule deer provide recreational bunting to a large number of sportsmen in Utah, and also have a high aesthetic value.

Prior to settlement, deer are believed to have wintered in the valleys and lower foothill areas. However, in northern Utah agricultural development bas removed many valleys and lower foothill areas from the available winter range. The winter deer range in this area has therefore been restricted to a relatively small area of foothill country, and low elevation mountain slopes and benches.
