The Effect Of Pregnancy And Parturition On The Weight Of Dairy Cows, R. F. Morgan, H. P. Davis Mar 1936

The Effect Of Pregnancy And Parturition On The Weight Of Dairy Cows, R. F. Morgan, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A study was made of the effect of pregnancy and parturition upon the weight cycle of dairy cows of the Ayrshire, Guernsey, Holstein, and Jersey breeds according to gestation periods from data accumulated from records for the period 1922 to 1934 of the dairy herd of the Dairy Husbandry Department of the University of Nebraska. The weights of the cows were obtained from three consecutive weighings made at the middle of each month and daily weighings beginning at the 265th day of pregnancy and continuing for 30 days after calving. A total of 656 separate gestation periods were tabulated according …

The Utilization Of Nitrogen, Calcium, And Phosphorus By The Growing Chick, C. W. Ackerson, M. J. Blish, F. E. Mussehl Sep 1935

The Utilization Of Nitrogen, Calcium, And Phosphorus By The Growing Chick, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. The nitrogen, calcium, and phosphorus content of 127 newly hatched chicks was determined. 2. Thirty newly hatched chicks were fed accurately known amounts of a good chick mash for 60 days. At the end of the period nitrogen, calcium, phosphorus, and fat were determined for each chick. 3. By means of the comparative slaughter test the retention of nitrogen was found to be 37.8 per cent, calcium 43.4 per cent, and phosphorus 27.3 per cent of the respective elements fed. 4. The average gain in live weight per gram of nitrogen fed was 12.0 grams. 5. The rate of …


A Comparative Histological Study Of The Eyes Of Certain Cave Animals, William Owsley Aug 1935

A Comparative Histological Study Of The Eyes Of Certain Cave Animals, William Owsley

Masters Theses & Specialist Projects

As early as 1850 many reports of observations of the blind cave animals were made by both scientific and popular writers. Tellkempf, Agassiz, Forbes and Silliman were some of the earlier scientists who studied the eyes of cave animals. Eigenmann made a histological study of the cave vertebrates of America. In a study of Forbesichthys papilliferus, a semi-blind cave fish, Jennie Miller Orr found important structural modifications in the eyes of this species. Since no comparative histological studies of the eyes of cave animals seem to have been made, it was decided to make such a study with a view …

Notes On The Distribution Of Amphibia And Reptilia Of Ellis County, Kansas, Lawrence A. Brennan May 1935

Notes On The Distribution Of Amphibia And Reptilia Of Ellis County, Kansas, Lawrence A. Brennan

Master's Theses or Doctor of Nursing Practice

Comparatively little has been done concerning the listing or recording of the Amphibia and Reptilia of Ellis County, Kansas. What records there are of the species are for the most part unpublished. Early papers dealing with Kansas herpetology are few in number. Little has been done in Ellis and the surrounding counties, so there seems to be a need for such an ecological study as has been carried out in this paper “Notes on the Distribution of Amphibia and Reptilia of Ellis County, Kansas . " The objectives kept in mind in preparing this report have been to attempt to …

A Taxonomical, Morphological And Distributional Study Of The Utah Cyprinidae /|Cby Sheldon Phipps Hayes, Sheldon Phipps Hayes

Theses and Dissertations

The hydrography of Utah may be thought of as being roughly divided into two large general drainage areas--, the Colorado River draining the eastern halt and southern portion ot the state and the Bonneville Drainage encompassing the remaining part of it. Earlier workers have listed eight genera and fourteen species of minnows occuring in Utah. Of these this report includes seven genera and ten species found within the borders of our state.

Determining The Sex Of Day Old Chicks, H. E. Alder Mar 1935

Determining The Sex Of Day Old Chicks, H. E. Alder

Nebraska Agricultural Experiment Station: Historical Circulars

More than 2,000 years ago people were interested in determining the sex of the embryo in hatching eggs and the sex of day-old chicks. No method of determining the sex of day-old chicks (except of course in sex-linked chicks) was of the slightest value until the Japanese method was discovered and developed. About 1925 Japanese scientists discovered the presence of a rudimentary copulatory organ located on the ventral rim of the cloaca which was present in all day-old males and only a few day-old females.

Probolitrema Tomalis Sp. Nov. (Trematoda) From Dasyatis Dipterura And Brachylaemus Virginianus (Dickerson) (Trematoda) From Didelphys Virginiana, Elsie Mae Graves Jan 1935

Probolitrema Tomalis Sp. Nov. (Trematoda) From Dasyatis Dipterura And Brachylaemus Virginianus (Dickerson) (Trematoda) From Didelphys Virginiana, Elsie Mae Graves

University of the Pacific Theses and Dissertations

The genus Probolitrema was established by Looss (1901) in recognition of the location of vitellaria and multiple testes entirely outside the extra caecal field in Anaporrhutum richardii Lopez (1888) which differentiated it from A.albidum Ofenheim (1900) with the vitellaria within and the testes partly within and partly without the intra-caecal field. Ofenhein had created the genus Anaporrhutum for the above two species because of their multiple testes. A.albidum was a new species described by him; his A.richiardii Lopez specimens he considered to be the same species as Distomum richiardii Lopez, described in detail by Monticelli in 1893. Looss pointed out …


Notes On The Owls Found In Lincoln County, Nebraska, Wilson Tout Jan 1935

Notes On The Owls Found In Lincoln County, Nebraska, Wilson Tout

Papers in Ornithology

During more than a quarter of a century I have been making notes and collecting information about the Owls of Lincoln county and it seemed an opportune time to put this information into print that it might be available to those who are interested in birds and serve as a basis for further study and amplification. Lincoln County is not usually considered a favorable place for Owls to reside on account of the absence of heavy timber over most of its area. But the nine varieties listed will probably be extended as more observations are made by those who are …

Studies On A Cave Fish Of Uncertain Classification, Jennie Miller Orr Aug 1934

Studies On A Cave Fish Of Uncertain Classification, Jennie Miller Orr

Masters Theses & Specialist Projects

The specimens studied during this investigation were taken incidentally during a general faunal survey of certain peculiar streams flowing from underground channels. On casual examination it was evident that they belonged to the cave fish group but were not the well known almost colorless blind variety. After checking the descriptions in various vertebrate manuals it appeared that they were probably a new species.

There are three groups of cave fishes, the non-blind, the semi-blind and the blind. Chologaster, or the Rice Field Minnows of South Carolina, are members of the non-blind group. Forbesichthys of southern Illinois and Kentucky is an …


The Vitamin E Content Of Certain Dairy Feeds, I. L. Hathaway, H. P. Davis Aug 1934

The Vitamin E Content Of Certain Dairy Feeds, I. L. Hathaway, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A study was made of the vitamin E content of each of the ingredients of our dairy herd ration, excepting the salt, lime, and bone meal. Female rats which were able to conceive but unable to reproduce when fed a diet deficient in vitamin E were fed the various feeds as a source of vitamin E during a second breeding period. The presence of vitamin E in a feed was thus shown by the ability of the female to cast a litter. The vitamin E content of bran, shorts, linseed oil meal, hominy feed, white corn, yellow corn, cottonseed meal, …


Some Observations On Humidity And Weight Loss In The Incubation Of Turkey Eggs, F. E. Mussehl, C. W. Ackerson Aug 1934

Some Observations On Humidity And Weight Loss In The Incubation Of Turkey Eggs, F. E. Mussehl, C. W. Ackerson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. Turkey eggs which are incubated under chicken hens lose from 11 to 13 per cent of their original weight during the first 24 days of incubation. Small turkey eggs lose relatively more weight than large eggs incubated under the same conditions. 2. Considerable variation was observed in the weight loss during the first 24 days of incubation of eggs of approximately the same size when incubated in the same environment. The range was from 7 to 24 per cent of the original weight. Differences in shell texture may account for these variations, although care was taken to select only …
