A Study Of Local Size Variations In The Prairie Pocket-Gopher (Geomys Bursarius), With Description Of A New Subspecies From Nebraska, Myron H. Swenk

University of Nebraska State Museum: Mammalogy Papers

Beginning in the fall of 1913, the writer has continuously been interested in accumulating accurate body measurements, taken in the flesh, of Nebraska pocket-gophers. As a result quite an assemblage of such data has been secured. In the case of Geomys bursarius, the bulk of these data relates to specimens trapped in the vicinity of Lincoln, Lancaster County, involving to date 48 adult and 38 immature males and 50 adult and 65 immature females. Recently these measurements have been tabulated and compared with such measurements of the species as have been recorded in the literature from other parts of …

The Utilization Of Food Elements By Growing Chicks. Viii. A Comparison Of Alfalfa Meal And Artificially Dried Sudan Grass Meal In Rations For Growing Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

1. The effect of replacing the ten parts of alfalfa meal in a ration with artificially dried Sudan-grass meal on an equivalent protein basis was studied in a growth and body-analysis experiment with two lots of day-old chicks. 2. The chicks of both lots consumed equal amounts of dry matter during the feeding trial. 3. There were no significant differences in the growth rate or composition of the chicks at the end of a six weeks' feeding trial.

A Study Of The Variations In The Growth Of Blue Grama Grass From Seed Produced In Various Sections Of The Great Plains Region, Andrew Riegel

Master's Theses

During the past 7 years the Great Plains Region, with its "dust bowl", has been the scene of unparalleled activity in the fields of range management and erosion control. The people of this short grass area are extremely conscious of the need for a sound, practical program of conservation that will revegetate the wasted pasture and cultivated land, which will aid materially in preserving the eroding soil. Many problems have arisen as the program of conserving the soil and the vegetation has progressed.

A History Of The Changes In Population Of Certain Mammals In Western Kansas, Floyd L. Carter

Master's Theses

This particular study has been restricted to certain mammals in western Kansas, including some on which there is little information, and others which observers would be most likely to notice in everyday life. For several years the writer has been vitally interested in the animal life in Kansas. Therefore, when the need for a study of western Kansas mammals was presented to him in the summer of 1936, the problem of this study was selected. It is hoped that this report will suggest to ecologists, historians, and others, further studies, including reasons for the changes here-in shown. What have been …

A Comparative Study Of The Spiracle In Cyclostomata, Elasmobranchii And Pisces, Miser Russell Richmond

Masters Theses

(From the Introduction)

Although scientists have been interested in the spiracle for a number of years, very little investigation has been done. In this study the writer shall endeavor to describe the structures and functions of the spiracle in the Cyclostomes, Elasmobranchs and Pisces as well as show the continuous development of any structure as to its function in the animals studied.

Trichomoniasis Of The Utah Agricultural Experiment Station Dairy Herd, Rue Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bovine trichomoniasis is a venereal infection that reduces the fecundity of cattle. It is caused by Trichomonas foetus (Riedmuller), a flagellated protozoan which inhabits the genital tract, causing inflammation and partial sterility. Both sexes are susceptible to infection. In females it is usually of short duration and frequently terminates spontaneously following abortion. In males the disease has both acute and chronic stages. During the acute stage the prepucial membranes become inflamed and a muco-purulent discharge develops in which trichomonads are abundant. In the following chronic stage symptoms disappear, but the animal remains a carrier and is a dangerous source of …

The Utilization Of Food Elements By Growing Chicks. Vii. A Comparison Of Corn And Kalo In A Ration For Growing Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

1. The effect of replacing 31 per cent of ground corn in a ration by 31 per cent of ground kalo was studied in a growth and body-analysis experiment with two lots of newly hatched chicks. 2. The amounts of feed consumed by all chicks of both lots were kept identical by hand-feeding equal amounts of the pelleted rations daily. 3. There were no significant differences in the growth rate or composition of the chicks at the end of a six weeks' feeding trial.

Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott

Nebraska Agricultural Experiment Station: Historical Circulars

In Nebraska, a hustling frontier state in 1887, the legislature hesitated not at all in taking advantage of the provisions of the Hatch Act, and now that fifty years have elapsed since the Station was founded, seventy-five years since the Land Grant College Act was passed and the U. S. Department of Agriculture established, and almost twenty-five years since the Agricultural Extension Service was added, it seems worth while to present a general summary of achievement within the state. The main object will be to show some of the important things that have been learned through the investigations of the …

A Study Of The Structure Of Hair As A Means Of Mammal Identification., Earl R. Oyer

Master's Theses

The hair of small and medium sized mammals is often found in the stomachs, feces and pellets of predators , for example in the stomachs and feces of coyotes and in the pellets regurgitated by hawks and owls. These pellets produced by hawks and owls and the feces of mammalian predators are the undigested residue of what these animals have eaten. If the hair from these sources can be identified, then much desirable information concerning the food of predators can be obtained. The purpose of this study has been to determine whether or not such identification is possible.

The Utilization Of Food Elements By Growing Chicks. Vi. The Influence Of The Protein Level Of The Ration On The Growth Of Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

1. Two rations containing 16 and 22 per cent of protein respectively were fed to newly hatched chicks in two series of feeding trials. In one series the lower protein level was secured by diluting the higher with 30 parts of starch so that the amount but not the quality of the protein was changed. In the other series the amount and quality of the protein both varied since the two rations were mixed by using different proportions of the base and concentrate to yield the 16 and 22 per cent levels in the finished rations. 2. Comparisons were made …

Birdbanding, Frederick C. Lincoln

United States Fish and Wildlife: Staff Publications

Birdbanding, by means of numbered bands, provides a method of studying living birds of all kinds. Scientific banding dates back to 1899, when a Danish schoolmaster, H. Chr. C. Mortensen, commenced systematically to band storks, teals, starlings, and two or three species of birds of prey. His success at once attracted the attention of European ornithologists, and it was not long before the birdbanding work came into prominence. At the present time banding is being actively conducted in North America as well as in England, Finland, Norway, Sweden, Denmark, Russia, Iceland, Germany, Holland, Belgium, France, Switzerland, Hungary, Bulgaria, India, Morocco, …

The Efficiency Of Churn Washing Method And The Keeping Quality Of Butter As Indicated By Yeast And Mold Counts, T. Allen Evans

Electronic Theses and Dissertations

Of all the equipment used in the manufacture of butter, no single piece has as close contact with the finished product as does the churn while at the same time no piece of equipment is more difficult to keep properly cleaned. The workers in the dairy industry have expended much time and effort attempting to build a churn which could be kept in a more satisfactory state, especially from a bacteriological point of view. As yet no satisfactory material for churn construction has been found to replace wood which at best is difficult to keep free of micro-organisms. Since it …
