A Preliminary Study Of The Siphonapterous Ectoparasites Found On The Mammals Of The Families Cricetidae And Muridae In Utah County, Vernon J. Tipton

Theses and Dissertations

The purpose of this study was to determine the species of fleas infesting the mammals of the families Cricetidae and Muridae in Utah County. This was accomplished by establishing twelve collecting stations throughout the county from which 198 mammals were collected. From these hosts, 392 fleas were collected representing three families, nineteen genera , and twenty-four species. Four species are new to the State of Utah and twenty-two species are recorded from Utah County for the first time.

The Diet And Daily Forage Consumption Of An Experimental Herd Of Sheep On Utah's Winter Range, Lee A. Sharp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The forage produced on Utah’s winter range is generally deficient in some nutrients that are required for the phase of sheep production that takes place on these ranges. This forage need only supply little more than maintenance ration, but because of low forage production on these areas and generally low quality forage, these requirements often are not met.

The Introduced Fishes, Game Birds, And Game And Fur-Bearing Mammals Of Utah, Boris Hewitt Popov

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For a number of years wildlife workers have realized the importance of the past histories of introduced species. Emphasis in recent years has been directed toward introductions because of the tremendous hunting and fishing pressures. Yearly increases in numbers of hunters and fishermen have been noted in Utah for the past forty years. It is hoped that this compilation of the histories of the introduced game and fish species of Utah will be of value to sportsmen and wildlife managers alike in planning future introductions.

The material included in this paper was obtained from United States Government reports, Utah Territorial …

An Additional Trematode From Tortugas, Florida, And A New Name For Opisthoporus Manter, 1947, Preoccupied, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

Professor José M. Ruiz of Sao Paulo, Brazil, has kindly called my attention to the fact that the generic name Opisthoporus Manter, 1947 had been used several times previously, a condition which I had indeed checked but thoughtlessly forgot. For Opisthoporus Manter, 1947 (nec Opisthoporus Benson, 1851; Opisthoporus Minot, 1877; Opisthoporus Fukui, 1929), the name Postporus is proposed. The two species become Postporus epinepheli (Manter, 1947) and Postporus mycteropercae (Manter, 1947).

The combination Pleurogonus candidulus (Linton, 1910) (misspelled "candibulus" in my paper) had been made in 1946 by Ruiz (1946: 295) where, however, it was first printed " …

Systems Of Producing Fat Yearlings For South Dakota, William Clark Mccone

Electronic Theses and Dissertations

About twelve billion pounds of dressed beef and veal were produced in the United States in 1947 through the conversion of grassland crops into meat by cattle and these cattle lead all classes of American livestock in the consumption of grass and grassland crops. Grass usually represents the principal and cheapest feed for beef cattle. They utilize about one third of the permanent pastures and three fourths of the range areas. Pastures may be regarded as a costly source of feed only on highly productive farm lands, but their use in rotation with cultivated crops on such land is certain …

The Apparent Digestibility By Sheep Of Prairie Hay Harvested At Three Stages Of Maturity, Robert Manseau Jordan

Electronic Theses and Dissertations

Grass is the greatest asset of the Northern Great Plains. Grass does and must serve as the basic feed for the flocks and herds of this area. Without grass, much of the Northern Great Plains would be waste land with little or no value. In the states of North and South Dakota, Nebraska, Colorado, Wyoming, and Montana, about 67 per cent of the total land is in pasture and hay. Seventy five to 95 per cent of the total feed needed by cattle and sheep in the Northern Plains states is furnished by pasture and roughage. With an ever-increasing demand …

The Lemming Vole, Synaptomys Borealis, In Northern Minnesota, Ralph M. Wetzel, Harvey L. Gunderson

University of Nebraska State Museum: Mammalogy Papers

Lemming voles of the subgenus Mictomys have never been recorded from north-central United States, although they might be expected to occur there judging from records of the species Synaptomys (Mictomys) borealis from southern Manitoba. Recently, examination of specimens in the collection of the Minnesota Museum of Natural History reveals that Synaptomys borealis does occur in north-central United States for we have found the following specimens referable to that species: one immature female (No. 951, MMNH) from Williams, Lake of the Woods County, Minnesota, collected by Gustav Swanson, August 5, 1932; one adult male (No. 2552, MMNH) from Warroad, Roseau County, …

The Effect Of Age Of Gilt On Size Of Litter, Clifford Inman Iverson

Electronic Theses and Dissertations

Size of litter is an important consideration in determining the profits from a swine production enterprise. Basic information concerning factors affecting litter size is, therefore, pertinent to the swine production industry. This study was conducted to ascertain the effect of age of gilt on the size of their first litters.

A Survey Of The Adult Trematodes From Fishes Of The Pacific Marine Station Area, William Franklin Johnson

University of the Pacific Theses and Dissertations

An effort is here made to assemble all of our knowledge of all adult trematodes which have been found in the fishes of the Pacific Marine Station Area. This includes publications, unpublished material such as graduate theses, and specimens herein described for the first time. It is hoped that this endeavor will facilitate further investigation in trematodology and that this paper will be an aid in identification of trematodes subsequently discovered.

Studies On Larval Trematodes From Tomales Bay, California, Leroy H. Fisk

University of the Pacific Theses and Dissertations

Very little is known of the development, life history, economic importance, of biological relationships of larval trematodes, especially in their molluscan and arthropod hosts on the Pacfic Coast. The comparatively few contributions to our knowledge have been from scattered and fragmentary observations. The purpose of this study was to expand our knowledge and to lay a foundation for further work on trematode life cycles in marine organisms. The area selected for special investigation was Nick's Cove, Tomales Bay, California.

Trypsin Inhibitor. Vii. Comparative Nutritive Value Of Raw And Heated Soybean Meal For Poults, C. W. Ackerson, Raymond Borchers, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

I. The trypsin inhibitor contained in one-half of a lot of soybean meal was destroyed by autoclaving at 15 pounds for 20 minutes. 2. This portion of the meal when fed at a level of 24 per cent to newly hatched poults gave a significantly greater gain in five weeks than did an equal amount of meal in which the inhibitor had not been destroyed. 3. The difference in growth is attributed to the destruction of the trypsin inhibitor.

The Influence Of Length Of Storage Of Bovine Semen On Conception Rate Under Field Conditions, A. B. Schultze, H. P. Davis, C. T. Blunn, M. M. Oloufa

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the purpose of this study to determine whether under conditions of routine handling in artificial breeding associations there is a decline in semen fertility from day to day and also to determine the magnitude of this decline. Tabulation of such data will not only be of value in determining the effect of frequent semen collection on the over-all artificial breeding results but will also serve as a basis of comparison in investigational work directed toward increasing the efficiency of artificial breeding.

Processing, Grading And Sale Of Utah Turkeys, 1947-48, Paul R. Grimshaw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Turkey production in Utah is one of the most important farm enterprises of the state. In 1945, 11.5 percent of the total farm cash income of the state was from the turkey enterprise. In 1946, 9.4 percent came from this source. Turkey production made up 8.9 percent of the total cash income from farm enterprises in 1944; 5.8 percent in 1945; 4.9 percent in 1940; 1.7 percent in 1935; and 1.3 percent in 1930. The objectives of this study were: (1) to ascertain charges for processing and hauling turkeys from the farm to the processing plants; (2) to determine the …

The Effect Of Ddt Residue On The Composition And Digestibility Of Alfalfa Hay, Than Myint

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

DDT (2,2 bis (p-chlorophenyl) 1,1,1-trichloroethane) was first synthesized in 1874 by Seidler in Switzerland, however, its effectiveness as an insecticide was not known until about 1942. The active principle was first known as G.H.B. (Gesarol-Neccid Base): but in 1943 DDT was suggested as an abbreviation for Dichlore Diphenyl Trichloroethane (Kaaegie, 1946). In fact DDT, as a powerful insecticide is one of the developments made during World War II. The importance of DDT in the control of the common insect enemies of mankind, such as mosquitoes, flies, moths, and many agricultural insect pests is realized more day by day. Many studies …

Life Histories Of North American Nuthatches, Wrens, Thrashers And Their Allies: Order Passeriformes, Arthur Cleveland Bent

Papers in Ornithology

An attempt has been made to give as full a life history as possible of the best-known subspecies of each species and to avoid duplication by writing briefly of the others and giving only the characters of the subspecies, its range, and any -habits peculiar to it. In many cases certain habits, probably common to the species as a whole, have been recorded for only one subspecies. Such habits are mentioned under the subspecies on which the observations were made. The distribution gives the range of the species as a whole, with only rough outlines of the ranges of the …

Breeding Efficiency In Dairy Cattle From Artificial Insemination At Various Intervals Before And After Ovulation, George W. Trimberger

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The length of estrus and the time of ovulation were determined for 46 heifers and 86 cows of the Ayrshire, Guernsey, Jersey, and Holstein breeds by testing for end of estrus and ovulation at 2-hour intervals. Services were given by artificial insemination at various intervals before and after ovulation to determine the influence of this factor on the rate of conception. No significant breed or seasonal differences were found for length of estrus and ovulation time after end of estrus among the four dairy breeds represented in the experiment.
