Evidence Of Dinosaurs In Nebraska, Erwin Hinckley Barbour

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

Nebraska has long been a collecting ground famous for its fossil mammals, but as yet no dinosaurian bones have been reported, nor have they been expected. The distal end of a finely preserved femur, however, has recently been brought to light, supposedly occurring in position in the Dakota formation of eastern Nebraska. It was discovered, collected, and donated by Mr. J. B. White, (University of Nebraska, Law, class of 1899) on his farm two miles south of Decatur, in northeastern Burt County, near the Missouri River. It was found in undoubted Dakota sand associated with many leaf impressions. This is …

The Giant Beaver, Castoroides, And The Common Beaver, Castor, In Nebraska, Erwin Hinckley Barbour

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

Respecting the giant beaver, Castoroides, in Nebraska, four occurrences can be reported. Of rodents in general the dawn. was in the early Eocene, at which time there were in existence certain squirrel-like members of the order. Rodents are a persistent group, and are among the smallest, most distinctive, most numerous and widely distributed orders of terrestrial mammals. No other order boasts of so many species, the number being between nine hundred and one thousand. In spite of wide divergencies and modifications adapting them to various modes of life, such as climbing, burrowing, swimming, flying, leaping, and running, there is remarkable …

Comparative Metabolism Of Several Calcareous Minerals In Poultry Feeding, John T. Tripp

Electronic Theses and Dissertations

In part one of this study it was found that chickens when given oyster shells, in addition to their regular diet, produced a greater number of eggs and eggs of greater shell strength than did the chickens that were given the other calcareous materials used in this experiment. Oyster shell was followed in the order of their effectiveness by clam shells, Black Hills limestone, Nenno chalk stone, and Wisconsin dolomitie limestone.

The Spleen Considered With Special Reference To Its Functions, Louis J. Schmidt

Bachelors’ Theses

In arranging this thesis an attempt has been made to show that by virtue of its embryology, anatomy and histology, the spleen is the better enabled to carry out its alleged functions. The discussion here presented is confined to a story of the functions of the mammalian spleen alone. The similarities in the reactions of the spleen in the various mammalia is quite evident. Experimentation and observations were carried out on the lower mammalia while only the reactions of the splenectomized humans could be observed.

The Spleen: With Special Reference To Its Origin And Comparative Morphology, Morris Aaron Gilbert

Bachelors’ Theses

Throughout the ages the spleen has been an object of the most active curiosity. The opinion that the spleen is unnecessary and of no use to the individual has prevailed with an uninterrupted succession in the World in all ages. In Persia, many centuries ago, in the reign of Abouserous it was a custom to splenectomize the horses that were kept to carry the King’s dispatches, in order to give them more agility and swifter feet. The great Aristotle thought the spleen to be a sort of spurious liver planted in the left side to correspond to the liver in …

The Spleen Considered With Special Reference To Its Physiology As Determined Mainly From Splenectomy, Frank X. Schuler

Bachelors’ Theses

The spleen is essentially a vertebrate organ and its steady persistence throughout the group is an indication of its importance. Comparative study shows that it has certain common structural features , which may be counted fundamental or essential. In some animals, for example, in mammals, there are found additional structures, notably lymphoid tissue and splenic muscle often regarded as secondary acquisitions.

Bulletin No. 223 - Feeding Value Of Alfalfa Hay Treated With Calcium Arsenate, H. J. Frederick

UAES Bulletins

For a number of years many tons of sprayed or dusted hay have been fed successfully to livestock by stockmen interested in controlling the alfalfa weevil; nevertheless. the supposed cases of poisoning that have been reported naturally have caused concern among feeders.

Further confusion on this question has resulted from reports on studies designed to determine the effect of lead arsenate instead of calcium arsenate.

Whether the lead in lead arsenate has been a more injurious agent than the arsenic, of course, is difficult to state. Most of the experiments performed in the feeding of sprayed or dusted hay have …

Circular No. 90 - Swine Production In Utah, Harry H. Smith

UAES Circulars

During the last 20 years there has been a marked change in the type of hogs from the short-legged, wide-bodied or "hot-blood" type to a longer, somewhat more narrow-bodied, "leggier" type. For development of size in hogs they must have (1) length and depth of body, (2) length of leg, and (3) large but not coarse bones. The long-bodied rather "leggy" pig grows rapidly and makes the larger hog. While the modern hog is still a lard hog, it is not as thick and broad as were its predecessors. It is logical to assume that the hog of the future …

The Food Habits Of The Ring-Necked Pheasant In Central Nebraska, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Pheasants, including the Chinese and the so-called English pheasants, with their hybrid the ring-necked pheasant, have been introduced and established in a large area in the northern United States during the past 50 years. During the past 15 years continued importations of these birds into Nebraska, together with the rapid increase of those already established, have built up a large pheasant population in the state, estimated at more than a million birds. They have especially thrived in a block of 16 counties in east-central Nebraska. Protection was afforded them until 1927, when short open seasons were permitted in the fall …

Bulletin No. 221 - Snakes Of Utah, Herbert J. Pack

UAES Bulletins

For 17 years the late Dr. Herbert J. Pack, former Station Entomologist, made a study of the reptiles and amphibians of Utah. His original idea was to publish a comprehensive treatment of the snakes and lizards of his state, and whenever opportunity was afforded collected data on their distribution, habits, and economic importance. At the time of his death, on January 5, 1930, many notes and drawings of lizards were left; a manuscript on snakes, presented for his master's thesis to the Utah State Agricultural College in 1923, was also in his possession. Bulletin 221 contains essentially the information presented …

The Incidence Of Avian Tuberculosis In Mammals Other Than Swine, L. Van Es, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The recognition of a very widespread and intense distribution of avian tuberculosis on the farms of a wide area of the United States, as well as the involvement of a mammalian species also, brought to the foreground the question whether or not the great prevalence of poultry tuberculosis could be of importance also from a public health point of view. This phase of the problem not only pertains to the people on the farms but likewise is of fundamental importance to the consumers of poultry produce. European authors had already identified the avian tubercle bacillus in human lesions while in …

Underground Plant Development In Its Relation To Grazing, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Grasslands or grazing lands are relatively dry lands. Drought, at least in the surface soil, is always imminent. The necessity for the seedling to make immediate and extensive contact with deeper, moister soil is apparent. The water relation is usually controlling, and the success or failure of the seedling largely depends upon its ability to develop an absorbing system adequate in extent and activity to furnish the necessary supply.

Circular No. 86 - Coccidiosis Of Chicken, D. E. Madsen

UAES Circulars

Coccidiosis is a highly contagious disease of chickens and other fowls which is widespread and destructive, especially to half-grown chickens. The heaviest losses occur in chicks from 2 to 10 weeks of age. Just prior to and during their first laying season, pullets sometimes become affected with the disease in a chronic form. The cause is a microscopic protozoan parasite, the oocyst form of which is present in the droppings of diseased birds in large numbers. At least three species of the parasite have been recognized in fowls. The severity of the outbreak is thought to be determined by the …

Bulletin No. 218 - The Alfalfa-Seed Chalcis-Fly In Utah: 1926-29, Inclusive, Charles J. Sorenson

UAES Bulletins

During the past 10 or 15 years alfalfa-seed has constituted the major crop in western Millard County and in most of that portion of the Uintah Basin which is situated in Utah. In these sections of the state various natural conditions generally have been favorable for seed production. Within the last five years seed growers have thought that one of the principal limiting factors of the industry has been the alfalfa-seed chalcis-fly. Accordingly, a preliminary survey in the seed districts of the state was made in the fall of 1925 by the Utah Agricultural Experiment Station.

The greater part of …

Circular No. 87 - Raising Dairy Calves, George B. Caine

UAES Circulars

Too much importance cannot be given to the number and kind of calves raised. The life of an average cow is 6.5 years. To maintain the present number of cows in Utah about 15,385 heifer calves should be raised annually. One-half of all calves born are males and are usually disposed of in a few weeks; the other 50 per cent are females from which selection must be made to maintain the herds. In many parts of Utah the number of dairy cows should be increased and probably the best way to accomplish this is to raise carefully selected calves.

Laboratory Applications Of Present Day Knowledge Of The Hormone Of The Anterior Lobe Of The Pituitary Gland, Herman F. Geske

Bachelors’ Theses

The history of a pregnancy diagnosis is an old one. In the report of Dr. S. Ashheim is a note which bears this out. The women of ancient Egypt used a rather crude method. Whether it was an efficient test the records do not state. Considering the fact that pregnancy and germination and growth are correlative, these women of the Nile probably were not so far wrong theoretically, whatever the practical results may have been. Their method was to put barley and wheat grains in a pot. These grains were wettened with urine from a woman who thought herself pregnant.

Circular No. 85 - Chlorosis Yellowing Of Plants: Cause And Control, F. B. Wann

UAES Circulars

Chlorosis is a disease of plants, the characteristic symptom of which is the yellowing of the leaves. The disease is of sporadic but widespread distribution in Utah and the aggregate losses caused by it are undoubtedly greater than those of any other one disease. Not only are many plants killed, or weakened to such an extent that only inferior crops are produced, but many areas of land which might otherwise support profitable orchards have been abandoned or planted to other crops because of the disease.

Economic Aspects Of Contagious Abortion In A Dairy Herd, Department Of Animal Husbandry

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The object of this study is to present the measurable losses due to abortion in a dairy herd of high-producing ability over a period of approximately one-third of a century. The records available provide a rather complete history of what has taken place.

A Study Of Bull Associations, Arthur J. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

"A cooperative bull association", according to the United States Department of Agri culture, is "a farmers' organization formed for the purpose of joint ownership, use, and exchange of high class, purebred dairy bulls."

The members of the association are divided into three or more groups of neighboring farmers, each group being known as a block. A block may consist of one herd or several herds and contains from 40 to 60 cows. One bull is used in each block, and in order to prevent inbreeding, each bull is moved to another block every two years. If all the bulls live …

A Research Study Of Lamb Feeding In Winter Dry Lots At Monroe, Utah, 1928-29, George R. Henderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

By reason of the topography of the land, Utah is and probably will remain a livestock grazing state. As far as agriculture is concerned over 90 percent of the area is suitable for grazing only. This grazing range is used by cattle and sheep.
