Worm Parasites Of The Brown Rat (Mus Norvegicus) In The Philippine Islands, With Special Reference To Those Forms That May Be Transmitted To Human Beings, Marcos A. Tubangui Dec 1931

Worm Parasites Of The Brown Rat (Mus Norvegicus) In The Philippine Islands, With Special Reference To Those Forms That May Be Transmitted To Human Beings, Marcos A. Tubangui

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

Besides the role that they play as carriers and reservoirs of bubonic plague and other bacterial as well as spirochretal infections, rats often harbor parasitic worms, some of which are also a menace to human health. In view of this and because of the fact that the helminthic fauna of rats has never been studied extensively in the Philippine Islands, it seemed desirable to undertake a systematic examination of these animals for the purpose of finding out if they are infested with parasites that are transmissible to man.

The examination of nine hundred fifty rats (Mus norvegicus) …


Circular No. 96 - Crickets And Grasshoppers In Utah, W. W. Henderson Nov 1931

Circular No. 96 - Crickets And Grasshoppers In Utah, W. W. Henderson

UAES Circulars

In the written history of Utah, especially that which is reflected in diaries and journals of the pioneer settlers and that found in the oldest publications, there is ample evidence that one of the most serious handicaps to progress in this "far-western" territory was the cricket and its near kinsman, the grasshopper. Three basic resources on which the first permanent settlers counted were: (1) Good soil suitable for raising crops to sustain life; (2) suitable climate to make possible the maturing of wheat, corn, and vegetables; and (3) sufficient water of good quality not only for home uses but for …

The Influence Of Number Of Daily Milkings On The Production Of Dairy Cows, R. F. Morgan, H. P. Davis Sep 1931

The Influence Of Number Of Daily Milkings On The Production Of Dairy Cows, R. F. Morgan, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

High-producing Holstein, Jersey, Ayrshire, and Guernsey cows of various ages milked three times daily produced from 39.69 to 52.26 per cent more fat and from 44.98 to 65.18 per cent more milk than cows milked twice daily. When high-producing cows of all breeds milked four times daily were compared with cows milked twice daily, the fat production for the several age classes varied from 110.19 to 127.53 per cent and the milk production from 149.08 to 160.31 per cent greater for those milked four times. Milking high-producing cows four times as compared with three times daily showed an increased fat …


Studies Of Rickets In Swine, William J. Loeffel, Ray R. Thalman, F. C. Olson, F. A. Olson Aug 1931

Studies Of Rickets In Swine, William J. Loeffel, Ray R. Thalman, F. C. Olson, F. A. Olson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

During the years 1925 to 1929 inclusive, the Nebraska Agricultural Experiment Station carried on a series of four experiments to study the importance of the antirachitic factors in the nutrition of swine. Vitamin D as obtained from cod-liver oil and the radiant-energy factor of sunlight were the sources of the antirachitic factors that received primary consideration. Emphasis was placed upon the study of the symptoms and lesions produced in pigs fed a rickets-producing ration.


How Far Is The Argument Of Homology Acceptable To Reason, Wilmur Daniel Ackerman Jul 1931

How Far Is The Argument Of Homology Acceptable To Reason, Wilmur Daniel Ackerman

Bachelors’ Theses

Evolution is a subject that involves a great deal more than the average person really thinks about. To approach subject like this, one must try to obtain as many of the different factors that taken into consideration as is possible.

The Common Intestinal Roundworm Of Swine, H. M. Martin Jul 1931

The Common Intestinal Roundworm Of Swine, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Circulars

The large intestinal roundworm of pigs is a very common parasite, and is probably present in every hog raising district of Nebraska. Until the last few years the true nature of this parasite was unknown. Little did we realize the actual harm done by this worm; but through the scientific investigations of Stewart, Ransom, and others we now know that this parasite causes heavier losses to the breeder and feeder of swine than any other now common in Nebraska.


The Alkaloids, Felix F. Barre Jul 1931

The Alkaloids, Felix F. Barre

Electronic Theses and Dissertations

This thesis, presented for the degree of Bachelor of Science, provides a systematic chemical study of the alkaloids, a class of complex nitrogenous plant substances possessing basic properties. Barre opens by defining the alkaloids and surveying the various systems used to classify them, whether by natural versus artificial origin, chemical nucleus (pyridine, quinoline, or isoquinoline), volatility, or botanical family of origin, and outlines their general physical and chemical properties, including solubility, optical activity, and characteristic reactions with precipitating and color-test reagents.

The thesis details standard laboratory methods for the extraction and separation of alkaloids from plant material, including a step-by-step …


Circular No. 94 - Control And Eradication Of Bang's Abortion Disease, D. E. Madsen, W. H. Hendricks Jun 1931

Circular No. 94 - Control And Eradication Of Bang's Abortion Disease, D. E. Madsen, W. H. Hendricks

UAES Circulars

The seriousness of Bang's abortion disease in Utah has made it necessary to promote more definite plans toward its control and eradication. The economic losses encountered are brought about not only through the loss of the calves but by the lessened milk production and lessened sale value of the animals themselves. Breeding efficiency is lower and such cows are more subject to udder infections. Many states now require that cattle shipped into them be negative to the abortion test; indications are that more states will adopt similar regulations. The passage of such regulation by some states would seriously interfere with …


Bulletin No. 229 - Production Study Of 160 Dairy Herds: Wellsville, Utah, 1929, George Q. Bateman Jun 1931

Bulletin No. 229 - Production Study Of 160 Dairy Herds: Wellsville, Utah, 1929, George Q. Bateman

UAES Bulletins

The condensed milk plant located at Wellsville, Utah, could use more milk to an advantage. The dairymen of the section were anxious to supply this demand. The dairymen and manufacturers cooperatively planned a survey to determine by what means this demand could be brought about: Should the dairymen increase the size of their herds? If not, what could be done to increase dairy production?

Bulletin No. 230 - San Juan County Experimental Farm: Progress Report, 1925-30, Inclusive, James H. Eagar, A. F. Bracken

UAES Bulletins

San Juan County, located in the southeast corner of the state, has a dry-farm area of approximately 600,000 acres extending from Monticello 26 miles south to Blanding and 6 miles north to Peter's Hill and stretching from the Blue Mountains east 30 miles to the Colorado line. One-fourth to one-third of this area is covered with timber consisting mainly of pinion pine, oak brush, and juniper commonly called cedar. Both the juniper and pinion are of value as fuel and building material, and the juniper has an additional value for fence posts. While small areas have been cleared of timber …


Bulletin No. 227 - Soft-Curd Milk, R. L. Hill Jun 1931

Bulletin No. 227 - Soft-Curd Milk, R. L. Hill

UAES Bulletins

Data on the early studies on the curd character of milk are found in Utah Agricultural Experiment Station Bulletin 207 and, therefore, are not included here. The key to research in this field came to light with the development of the "Hill Test," the results of which were first published in 1923. This test furnished a means of quantitatively measuring the difference in curd character of various milks.

The term "soft-curd" milk originated with R. L. Hill to describe milk which on coagulation with pepsin or rennin forms a curd that is soft and clabbery in consistency, differing widely from …


Microsporogenesis In Lilium Formosum, Marcella Alice Zeman Jun 1931

Microsporogenesis In Lilium Formosum, Marcella Alice Zeman

Bachelors’ Theses

Anthers of Lilium formosum were collected ranging from the very young to the mature. Anthers used for the writing of this paper were gathered around Easter time or early April. The anthers were removed from the bud and the ends were cut off. Each anther was cut into three or four parts at right angles to their respective lengths. After the washing, infiltration, and imbedding was completed, sections were cut from eight to ten micra in thickness. Before staining the sections were placed in a solution of hydrogen peroxide to bleach for three hours. Flemming 's triple stain, a combination …

Utilization Of Proteins By The Growing Chick, F. E. Mussehl, C. W. Ackerson May 1931

Utilization Of Proteins By The Growing Chick, F. E. Mussehl, C. W. Ackerson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. There is a marked difference in the nutritive value of the various protein-contributing concentrates when used to supplement a corn-wheat basal ration which has been made complete for known vitamin and mineral essentials. 2. There is a great difference in the biological value even of animal protein concentrates. 3. Soybean meal produced a better growth rate than any of the other plant concentrates used. Cottonseed meal proved to have a greater growth-promoting value than did linseed oil meal. 4. The supplementing values of protein concentrates, one to another, is not quite as evident as one would expect if the …

Influence Of Clipping On The Yield Of Forage In Certain Pastures At North Logan, Utah, Newel Washburn May 1931

Influence Of Clipping On The Yield Of Forage In Certain Pastures At North Logan, Utah, Newel Washburn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

"Pasture is the natural food of all domesticated herbivore, especially the ruminant, and the only single feed upon which it can be maintained in health indefinitely."

Pastures rank next to the alfalfa hay crop in total production of forage far livestock in Utah. For approximately five months each year pastures turnish the cheapest supply of feed available for dairy production. Their improvement and utilization to the best advantage as a source of valuable feed in Utah has been overshadowed by the abundance of alfalfa hay with its rich supply of minerals and high quality protein. There is a potentiality of …


Circular No. 93 - Better Sugar-Beet Culture For Utah, George Stewart, D. W. Pittman Apr 1931

Circular No. 93 - Better Sugar-Beet Culture For Utah, George Stewart, D. W. Pittman

UAES Circulars

Utah was one of the first states to begin sugar-beet growing. The industry grew rapidly, favored by the climate, by the naturally productive soils, by the freedom from pests, and by the system of intensive irrigation agriculture. California and Utah were among the leading beet-producing states at the time of the World War, and under the stimulus of high prices they remained so until the great depression of 1920. After that, the frequent occurrence of curly-top and the rapid spread of nematode, together with the low price resulting from increased cane sugar production in the tropics and from other causes …


Bulletin No. 225 - Progress Report: Carbon County Experimental Farm, 1927-30, Inclusive, I. D. Zobell, George Stewart Apr 1931

Bulletin No. 225 - Progress Report: Carbon County Experimental Farm, 1927-30, Inclusive, I. D. Zobell, George Stewart

UAES Bulletins

The agricultural problems of the Carbon County Experimental Farm and of the locality which it serves are distinctly different from those of most of the farming localities of Utah. The low and uncertain winter rainfall, the comparative "rawness" of the soils, together with their almost infinite stickiness when wet, and the presence of considerable alkali throughout their body makes them peculiarly sensitive to time and manner of treatment and causes them to absorb water slowly and to erode readily.

The Vitamin A Content Of The Milk Of Holstein, Ayrshire, Jersey, And Guernsey Cows, H. P. Davis, I. L. Hathaway Feb 1931

The Vitamin A Content Of The Milk Of Holstein, Ayrshire, Jersey, And Guernsey Cows, H. P. Davis, I. L. Hathaway

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A comparative study of the vitamin A content of milk produced by Holstein, Ayrshire, Jersey, and Guernsey cows was made by comparing the growth produced by 560 rats receiving milk from these breeds as their only source of vitamin A. The results showed some slight irregular differences in the gains produced by the milk from the different breeds. When these differences were considered in view of the individual variation of the experimental animals, they appeared negligible. This conclusion was substantiated by a statistical examination of the data. From the results of this study in which the experiments were duplicated, it …

The Musk-Oxen Of Nebraska, Erwin Hinckley Barbour Jan 1931

The Musk-Oxen Of Nebraska, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

The remains of no less than eight fossil musk-oxen are already known in Nebraska, of which one is preserved in the Museum at Hastings, Nebraska, and seven in the State Museum at Lincoln. This is a large number to be recorded in anyone state. As late as 1891 authors wrote that but two examples of musk-oxen were known in the United States, one from Kentucky, and one from Arkansas, if, indeed, they be valid species. Now that pioneer days are well behind this commonwealth, and that there is a growing sentiment for exploration and proper display of the State's resources, …


A New Crinoid Slab, A Bit Of Mississipian Sea Bottom, Erwin Hinckley Barbour Jan 1931

A New Crinoid Slab, A Bit Of Mississipian Sea Bottom, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

Crinoids are popularly known as stone-lilies, featherstars, and sea-lilies. The word lily is a misnomer, and many, misled by the name and by the lily-like form, associate crinoids with the plant kingdom. The name, feather-star, seems explicit for it refers to the feathery arms surrounding the cup or calyx, and expresses relationship to the starfishes and their kind. The cup is attached to a stem, and the stem is anchored to the ocean floor by so-called roots, which are really hold-fasts, or anchors. These features may be seen in the diagram at the end.
