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 Mar 1939

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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 Mar 1939

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 Feb 1939

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

Master's Theses or Doctor of Nursing Practice

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 Feb 1939

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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 Jan 1939

Birdbanding, Frederick C. Lincoln

United States Fish and Wildlife Service: 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 Jan 1939

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 …

A Manual For Hog Raisers, W. J. Loeffel Oct 1938

A Manual For Hog Raisers, W. J. Loeffel

Nebraska Agricultural Experiment Station: Historical Circulars

Hogs are one of Nebraska's principal sources of agricultural income. The popularity of the pig is doubtless due largely to his efficiency as a meat producer. He uses less feed to make a given gain than either the steer or the sheep. On being slaughtered, the pig dresses out a higher percentage of meat than either of the other two meat animals. Since pork is generally fatter than beef or lamb, it has a higher energy value. Pork lends itself to curing processes and, as cured meat and lard, occupies an important place in the world's commerce. Processing aids in …


The Spinal Nerves And Spinal Cord Of The Frog, Laverne A. Penn Sep 1938

The Spinal Nerves And Spinal Cord Of The Frog, Laverne A. Penn

Bachelors’ Theses

The common grass frog, Rana pipiens as wall as the bull frog, Rana catesbiana have served during many decades as material from which both the student of zoology and the investigator in biological problems have gathered valuable information about the anatomy and physiology of the common systems. Among these systems the central, peripheral, and sympathetic nervous system plays a coordinating role, because of the ramifying nature of its organization. It is the purpose of this thesis to investigate the gross and histological structure of these branches known as spinal nerves. When one inspects the literature on the nervous system of …


Influence Of Age Of Dairy Cattle And Season Of The Year On The Sex Ratio Of Calves And Services Required For Conception, R. F. Morgan, H. P. Davis Aug 1938

Influence Of Age Of Dairy Cattle And Season Of The Year On The Sex Ratio Of Calves And Services Required For Conception, R. F. Morgan, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present study was based on records of the dairy herd of the University of Nebraska for the period 1896 to 1934, and covers five breeds, Holsteins, Jerseys, Guernseys, Ayrshires, and milking Shorthorns. In all, 2,090 cows have been included. The purpose was to determine the influence of the age of the bull, the age of the cow, and the season of the year upon the number of services required for conception, and to determine also the influence of these factors upon the sex ratio of calves born, number of twins born, and the percentage of abortion.


Feeding And Care Of Calves, R. R. Thalman Aug 1938

Feeding And Care Of Calves, R. R. Thalman

Nebraska Agricultural Experiment Station: Historical Circulars

It is not infrequent that considerable difficulty is encountered in raising calves with limited amounts of milk or none at all. Requests for information on calf gruels, mixed grain feeds, and commercial supplements are frequent enough to make a short circular upon this subject seem desirable. Furthermore, as the more diversified agricultural program gets under way these requests are increasmg.

Studies On The Vitamin A Content Of Cheese, I. L. Hathaway, H. P. Davis Jul 1938

Studies On The Vitamin A Content Of Cheese, I. L. Hathaway, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The vitamin-A contents of twenty-two kinds of cheeses were studied by feeding these cheeses to rats whose body stores of vitamin A had been exhausted by being fed a vitamin-A-deficient diet. Twelve experiments were made in which approximately 1100 rats were used. There was considerable variation in the vitamin-A content of the samples studied. The samples of cottage, Neufchatel, and Limburger cheeses had the lowest vitamin-A potency.


The Vitamin A Content Of Soybean Silage And Of A.I.V., Molasses, And Common Corn Silages, And The Effect Of Feeding These Materials Upon The Vitamin A Content Of Milk, I. L. Hathaway, H. P. Davis, J. C. Brauer Jun 1938

The Vitamin A Content Of Soybean Silage And Of A.I.V., Molasses, And Common Corn Silages, And The Effect Of Feeding These Materials Upon The Vitamin A Content Of Milk, I. L. Hathaway, H. P. Davis, J. C. Brauer

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A study was made of the vitamin A content of soybean silage, and of A.l.V., molasses, and common corn silage. The silages were fed to groups of cows and the vitamin A content of their milk determined. The vitamin A determinations were made by feeding the silage or the milk to groups of rats whose body stores of this vitamin had been depleted by being fed a vitamin-A-deficient ration. Approximately 780 rats were used in these experiments. There were no apparent ill effects of feeding as much as 3.2 grams of the A.l.V. silage per rat per day for eight …


The Utilization Of Food Elements By Growing Chicks. V. A Comparison Of Cottonseed Meal And Linseed Oil Meal As Portions Of The Protein Concentrate, C. W. Ackerson, M. J. Blish, F. E. Mussehl Jun 1938

The Utilization Of Food Elements By Growing Chicks. V. A Comparison Of Cottonseed Meal And Linseed Oil Meal As Portions Of The Protein Concentrate, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. Two lots of newly hatched chicks were fed rations differing only in five per cent of their make-up. In the ration of one lot five parts of linseed oil meal were added to 95 parts of the base, and in the other ration a mixture of 4.5 parts of cottonseed meal and 0.5 part of starch was added, to keep the protein level the same. The remaining portions of the two concentrates were made up of five parts each of meat scraps and fish meal. 2. The amounts of feed consumed by all chicks of both lots were kept …


Determining The Sex Of Day-Old Chicks, H. E. Alder Jun 1938

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.


A Photographic Study Of The Musculature Of The Dog, Francis Joseph Millen Jun 1938

A Photographic Study Of The Musculature Of The Dog, Francis Joseph Millen

Bachelors’ Theses

In this thesis the author has endeavored to construct a realistic study of the muscles of the domesticated dog. It has not been his purpose to discover anything new, but rather to make a complete study and outline of the more important muscles of the dog's hind limb.

For references the author has selected two widely known comparative anatomy books. In order that a more complete understanding be had of the muscles themselves, their morphology and physiology, and their orientation, the author also employed the use of several smaller texts of lesser renown. A list of the texts used can …


The Muscles Of The Forelimb Of Canis Familiaris, Charles G. Wilber Jun 1938

The Muscles Of The Forelimb Of Canis Familiaris, Charles G. Wilber

Bachelors’ Theses

In the study of the anatomy of the vertebrates, there has been much work done and a large number of the forms have been studied with great thoroughness. Among the domesticated animals this is particularly true. The students of the veterinary sciences have given us a deep insight into the structure and function of the mammalian body. This is most certainly true in the case of the dog. The species Canis familiaris has been used for many years in the studies of physiology and surgery. However, it is also true that a plenitude of literature relative to the anatomy of …


A Cytological Study Of The Ciliated Epithelium Of Nucula Castrensis Hinds., Dorothy Blumer Jun 1938

A Cytological Study Of The Ciliated Epithelium Of Nucula Castrensis Hinds., Dorothy Blumer

Electronic Theses and Dissertations

Ever since the latter part of the 17th century, when ciliary movement was first observed, the study of ciliated cells has been of great interest to biologists, particularly to physiologists. In 1713 Leeuwenhoek recorded some observations he made on ciliary activity, using his primitive microscope. A knowledge of the structure and function of ciliated cells is also of importance in that branch of medicine pertaining to disorders of the respiratory passages and the movement of the ovum in the uterine tubes. The bivalve molluscs have come to be the classical example for the study of ciliated cells, both because of …

Studies In Breaking The Rest Period Of Grass Plants By Treatments With Potassium Thiocyante And In Stimulating Growth With Artificial Light, Harold R. Shepherd May 1938

Studies In Breaking The Rest Period Of Grass Plants By Treatments With Potassium Thiocyante And In Stimulating Growth With Artificial Light, Harold R. Shepherd

Master's Theses or Doctor of Nursing Practice

There has developed a need for a practical means of artificially breaking the rest period and of stimulating the growth of grasses so that sods can be procured early in the fall before freezing weather, brought into the greenhouse, and forced early to make an abundant vegetative growth. This need suggested the study of which this paper is the report, namely to discover whether or not the rest period of native grasses can be broken by treatment with potassium thiocyanate and their growth stimulated by artificial light supplemental to winter daylight.


The Liver Of The Frog, Robert A. Grace May 1938

The Liver Of The Frog, Robert A. Grace

Bachelors’ Theses

The object of this paper is neither to contribute any new information, nor to criticize any work that has been done on the liver of the frog. The aim is merely to give a brief summary of the gross anatomy, the progress achieved in certain cytological fields, and the function of the liver in digestion and as a dietary factor. In doing this, the paper is intended to show the general trend of research which is apparent in current literature
