The Vitamin A Content Of Skimmilk, Standardized Milk, And Cream From Different Breeds Of Cows, I. L. Hathaway, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A study was made of the vitamin A content of skimmilk, of milk standardized by the addition of separated milk, and of cream. Rats whose body stores of vitamin A had been depleted by being fed a vitamin A deficient ration were fed either skimmilk, standardized milk, or cream as a source of vitamin A. Approximately 750 rats were used in nine experiments. From the results of these experiments the following conclusions were drawn: (1) that the vitamin A content of milk is associated largely with the butterfat and that separated milk containing a small quantity of fat contains only …

An Analysis Of The Habitat Distribution Of The Vertebrate Fauna Of A Stream- Bank Association In Western Kansas, Olive Falls

Master's Theses or Doctor of Nursing Practice

This present paper is chiefly concerned with the distribution of animals. The environmental and faunal conditions of Western Kansas have not been studied, and they are rapidly changing, due to human occupancy of the region. Therefore, a major object of this report is to put on record information in regard to the present vertebrate animal life in Western Kansas. Profound changes in the native conditions have already been recognized; for example, many animals have become extinct, and others are gradually vanishing. It is in the hope of contributing something of the facts of the status of the species in this …

A Study Of The Tolerance Of Certain Species Of Fishes For Low Dissolved Oxygen & Increased Carbon Dioxide Concentrations, Charles Allen

Masters Theses & Specialist Projects

Extensive investigations have been made of the oxygen end carbon dioxide content of water in which fishes live. A review of the literature, however, shows that these studies have not been made under controlled laboratory conditions dealing with the species studied in this investigation. It was the purpose of this study to determine the lowest concentration of dissolved oxygen that will support certain species of fishes and, also, the lethal effects resulting from increased carbon dioxide tension as determined under carefully controlled laboratory conditions.

A Morphological Study Of Daphniidae, Stanley E. Zawodny

Bachelors’ Theses

Th importance of fresh-water organisms is usually underestimated, especially by the very people who live near bodies of fresh-water and who thus can observe such organisms throughout the year. It is really easier to study minute life forms than it is to study larger organisms, for the former can be examined under all kinds of conditions as experiments are performed upon them. The purpose of this thesis is to give a short survey of the chief type among the fresh-water, Crustaceans, with special reference to morphology.

Bird Studies Of The Bear River Marshes, Ernest W. Parkinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The establishment of the Bear River Bay Bird Refuge has created for the state of Utah an immense and valuable biological field, a veritable paradise for naturalist and sportsman alike. The naturalist wants a place to study wild life and the sportsman desires game. With the proper control of open seasons on wild fowl the hunting instinct and incentive for the sport should be satisfied for the sportsman. To the naturalist this region will open up bountiful treasures of knowledge that is to be gained only by intense and prolonged scientific study.

Within this new field, and the limited time …

An Economic Study Of The Food Habits Of The Ring-Necked Pheasant In South Dakota, H.C. Severin, South Dakota Department Of Game And Fish

Natural Resource Management Faculty Publications

The economic status in South Dakota of the ring-necked pheasant (Phasinus colchicus torquatus Gmelin X Phasianus colchicus colchicus L.) has turned out to be a controversial matter of no small importance with the citizenry of the State. This bird was introduced into South Dakota mainly thru the efforts and funds of the State Department of Game and Fish, and thru this department the pheasant was protected form slaughter by hunters, and permitted to multiply. When it was believed that the pheasants hasd established themselves in a county and multiplied sufficiently to warrant an open season , such an open season …

The Pituitary, Thyroid, And Adrenal Glands Of The Opossum, Max F. Drozewski

Bachelors’ Theses

In recent years a great deal has been written on the endocrine glands. However most of the articles deal with the physiological function of the various ductless glands only. Very little of this literature deals with the anatomical structure of the organs themselves. In this thesis we shall discuss the anatomical structure of the endocrine glands namely, the Pituitary(hypophysis), Thyroid and the Adrenal of a marsupial. The work has been done on the opossum of the virginia species, Didelphis virginiana. Only two specimens were available for dissection.

The Endocrine Glands And Their Secretions, Eldred M. Moehrke

Bachelors’ Theses

In the following work the endocrine system was considered in general with special emphasis on the thyroid and para-thyroid glands. In some manner,which we do not well understand,the thyroid and the para-thyroid glands affect the other ductless glands and it is this relationship that is stressed.

General Morphology And Physiology Of The Urogenital System Of The Opossum, Robert Schuster

Bachelors’ Theses

From the very first, I wish the state that the title, "General Morphology and Physiology of the Urogenital System of the Opossum," is not entirely descriptive of the text which is to follow. However it is as nearly descriptive as I could hope to make it.

It seems that during the history of biological research the workers have done comparatively little work on the Opossum. This neglect was probably due to its inaccessibility, since it is found only in Australia and in the semitropic regions of North America. In the nineteenth century the eminent authority on anatomy, Sir Richard Owen, …

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 …

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 …

Swine Sanitation, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

From the very beginning of Nebraska's agricultural development its farmers have recognized that the production of swine must of necessity accompany the growing of corn. The latter, one of the state's most important staples, cannot be marketed in a more economical manner than after having been transformed into pork, bacon, and lard. As a result the state has for many years maintained a rather dense swine population mainly divided into large herds kept on relatively small areas of land. This density of population, as well as certain practices in management and selective breeding, has brought about conditions favorable for the …

The Abortion Problem In Farm Live Stock, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

Successful animal husbandry is fundamentally dependent on the efficient reproduction and preservation of young stock. Not only are losses among the latter a prolific source of direct economic damage, but they also tend to create an equally serious disadvantage of a more indirect nature. Losses of young animals, unless a reduction of our live stock population can be tolerated, necessitate the setting aside of a larger number of females for purely reproductive purposes than would be required if such losses were not a factor.

The Insects And Mites Injurious To Poultry In Nebraska And Their Control, M. H. Swenk, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

There are a number of different kinds of insect and mites (arthropods) that are more or less injurious to poultry in Nebraska. This circular is designed to give practical information concerning these pests and their control.

The Anatomy Of The Timber Rattlesnake, Ruth H. Heinemann

Bachelors’ Theses

Snakes are the most highly specialized of all reptiles. The absence of limbs, in itself, is a great specialization. They possess a great modification of the jaws which enables them to engulf large prey entire. Probably the most out­ standing specialization is the remarkable modification of dentition in the venomous snakes. The so-called fangs are nothing more than teeth modified to a great degree.

Nutrient Requirements Of Growing Chicks, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The object of our experimental work was to establish if possible certain principles of poultry nutrition, permitting later a better combination of natural feedstuffs with the highest growth efficiency.

The Tapeworms Of The Rhinoceroses, A Study Based On Material From The Belgian Congo, Horace W. Stunkard

Harold W. Manter Laboratory of Parasitology: Library Materials

During the course of my study on the parasitic worms collected by the Lang-Chapin expedition of the American Museum to the Belgian Congo, I have had the good fortune to examine abundant material of Plagiotaenia gigantea (Peters). This interesting species, the first reported from the rhinoceros, has been confused with other cestodes from rhinoceros hosts, has been assigned to no less than three different genera in addition to the genus Taenia, to which it was originally referred, and has been the source of much discussion and difference of opinion during the past seventy years. A review of the literature …

How To Study The Western Birds, Grace Mccormac French

Macnab, Dr. Jane Claire Dirks-Edmunds's mentor at Linfield College. The article mentions various books by bird-watching authorities and naturalists from around the Pacific Northwest.

Dirks-Edmunds, a 1937 graduate of Linfield, graduated from the University of Illinois in 1941; she returned to teach in the Biology department at Linfield from 1941-1974.

Trematodes From The Rat, Horace Wesley Stunkard, Chilson B. Haviland

Harold W. Manter Laboratory of Parasitology: Library Materials

Occasional examinations of rats for animal parasites have been carried on for over a hundred years. Later, knowledge of the importance of rats as reservoirs of infection and as agents in the transfer of parasitic diseases has led to the regular and careful examination of large numbers in various parts of the world. Among the more recent publications dealing with the parasites of rats may be mentioned Shipley (1908), Moll (1917), Chandler (1921), Balfour (1922), Baylis (1922), Stevenson (1922), Hegner (1923), and Lavier (1924). Notwithstanding the many investigations, only a single trematode parasite has previously been discovered and concerning it …

Bulletin 104 - The Stickfast Flea, John G. C. Campbell

Bulletins 1 - 2999

The insect which forms the subject of this Bulletin has raised great consternation in certain parts of this State by the trouble which it has caused amongst Poultry.

Fleas in general are notorious on account of the discomfort which they cause to man and animals, but, in this country none has a more evil reputation than the Stickfast Flea.

Studies Of Immunity Against Hemorrhagic Septicemia, L. Van Es, H. M. Martin

Bulletin No 81 - The Improvement Of Pastures With Notes On The Pasture Trefoils In Western Australia, E. A. Mann, D. A. Herbert

Bulletins 1 - 2999

Agriculture can be roughly divided for practical purposes into two large divisions, those of animal husbandry and vegetable husbandry. It is with the former that this pamphlet is chiefly concerned and its object is to contribute, it possible, in some small measure towards the problem of how to increase time stock carrying capacity of our natural pasture lands. it is unnecessary to dwell upon the importance of this question, especially in relation to the remarkable developments which are taking place in time wool-growing industry in the Southern and more coastal areas of Western Australia.

On A New Species Of Otter From Nebraska, Myron Harmon Swenk

University of Nebraska State Museum: Mammalogy Papers

In 1908 I referred our Nebraska otters to L. c. sonora (Rhoads), basing this conclusion on the mounted specimen in the University Museum, because of its large size and pallor, that being the only Nebraska specimen in any collection in the state at that time, and, so far as known to me, the only Nebraska specimen extant except the young female in the U. S. National Museum mentioned above. In 1915 I repeated this identification. The taking of a fine old male otter with a perfect skull in eastern Nebraska in 1916 reopened the whole question, and a close study …

On A New Subspecies Of Porcupine From Nebraska, Myron H. Swenk

University Studies (University of Nebraska) (1888–1984)

Publication NO.2 of the Nebraska State Biological Survey.

Nebraska porcupines all belong to the yellow-haired species (Erethizon epixanthum) , and these animals have never been abundant in the state. Formerly, however, they were much more numerous than today, and enjoyed a more extended range in the state than they do at the present time. Up to about 1885 these animals occurred across the northern portion of Nebraska east at least to Pierce and Madison counties, there being records of four specimens secured along the small streams tributary to the Elkhorn river in these two counties between 1870 and 1885. Also, …
