The Abortion Problem In Farm Live Stock, L. Van Es Sep 1923

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

Nebraska Agricultural Experiment Station: Historical Circulars

This casting out of a dead or at least abnormal fetus we call abortion. It constitutes the culminating accident in a process set into motion by disease or injury. To the breeder it is its most conspicuous feature, and it's more or less constant occurrence among live stock warrants us to speak of the abortion problem. It is the purpose of this publication to lay before our Nebraska breeders such information on the subject as can be gathered from the more recent literature and from observations in the field and the laboratory.


The Common Intestinal Roundworm Of Swine, H. M. Martin Mar 1923

The Common Intestinal Roundworm Of Swine, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Circulars

The large intestinal roundworm of pigs is a very common parasite, and is probably present in every hog raising district of Nebraska. Up until the last few years the true nature of this parasite was unknown. Little did we realize the actual harm done by this worm; but through the scientific investigations of Stewart, Ransom, and others we now know that this parasite causes heavier losses to the breeder and feeder of swine than any other now common in Nebraska.


Studies Of Immunity Against Hemorrhagic Septicemia, L. Van Es, H. M. Martin Aug 1922

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

As one of the phases of our inquiry an effort was made to acquire some general knowledge regarding the immunizing value (1) of sera prepared with the aid of Bacillus bipolaris septicus procured from cattle and swine or (2) of those alleged to be of service in the control or treatment of hemorrhagic septicemia in the species mentioned. The experiments reported in this publication were almost exclusively made with sera purchased from dealers in biologic products.


The Preparation Of Laboratory Specimens As An Aid To The Diagnosis Of Animal Diseases, L. Van Es, L. V. Skidmore Jun 1922

The Preparation Of Laboratory Specimens As An Aid To The Diagnosis Of Animal Diseases, L. Van Es, L. V. Skidmore

Nebraska Agricultural Experiment Station: Historical Circulars

Many problems in connection with animal diseases require for their solution the application of methods which can only be undertaken at properly equipped laboratories. This ordinarily involves the collection, packing, and shipping of samples of specimens. The manner in which this is done is a most important factor and to a very large extent is responsible either for the success or for the failure of the undertaking. The discussion of the subject to which the following pages are devoted is taken in hand in the hope that it may provide guidance to the veterinarians and others who may have occasion …


The Common Intestinal Roundworm Of Swine (Ascaris Lumbricoides), H. M. Martin Jun 1922

The Common Intestinal Roundworm Of Swine (Ascaris Lumbricoides), H. M. Martin

Nebraska Agricultural Experiment Station: Historical Circulars

The large intestinal roundworm of pigs is a very common parasite and is probably present in every hog raising district of Nebraska. Up until the last few years the true nature of this parasite was unknown. Little did we realize the actual harm done by this worm; but through the scientific investigations of Stewart, Ransom, and others we now know that this parasite causes heavier losses to the breeder and feeder of swine than any other now common in Nebraska.


Hog Houses For Nebraska, O. W. Sjogren, I. D. Wood Mar 1922

Hog Houses For Nebraska, O. W. Sjogren, I. D. Wood

Nebraska Agricultural Experiment Station: Historical Circulars

The material contained in this bulletin is a culmination of several years' study and investigation of the different types of hog houses used in Nebraska. It is realized that the plans given will not suit all conditions that may arise, but an effort has been made to bring out the essential factors so that the plans may serve as a guide in planning a house suited to particular conditions.


How To Select Good Layers, F. E. Mussehl Jul 1920

How To Select Good Layers, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Certain standard methods of selecting good laying hens have been developed as a result of observations made at the laying contests and at other places where trapnesting is being done.


Dairy Barn And Milk House Arrangement, J. H. Frandsen, W. B. Nevens Oct 1919

Dairy Barn And Milk House Arrangement, J. H. Frandsen, W. B. Nevens

Nebraska Agricultural Experiment Station: Historical Circulars

From an economic point of view, as well as from the standpoint of animal comfort, it is highly desirable that adequate barn or shed facilities be provided for the dairy herd. Some farmers have developed the idea that to keep cows healthy and comfortable and to produce sanitary milk it is absolutely necessary to have expensive barns. As a matter of fact, many of the dairy barns where sanitation is the primary object are quite inexpensive. On the other hand, if the barn is conveniently arranged and made to embody the most accepted sanitary features, it is very essential that …


Purebred Sires Effect Herd Improvement, M. N. Lawritson, J. W. Hendrickson, W. B. Nevens Jul 1919

Purebred Sires Effect Herd Improvement, M. N. Lawritson, J. W. Hendrickson, W. B. Nevens

Nebraska Agricultural Experiment Station: Historical Circulars

The real worth of a sire for the dairy herd can be established only when production records of the progeny are available for comparison with those of the preceding generation. A study of the following three sires which have been in service in the University of Nebraska dairy herd should be of interest to the Nebraska dairyman wishing to improve his own herd. This experiment indicates that the apparently high cost of a good herd sire is more than outweighed by the increase in the value of the progeny.


Outline Of Object And Plan Of The Nebraska National Egg Laying Contest, Nebraska Agricultural Experiment Station Jun 1919

Outline Of Object And Plan Of The Nebraska National Egg Laying Contest, Nebraska Agricultural Experiment Station

Nebraska Agricultural Experiment Station: Historical Circulars

To promote the breeding of high laying strains of standard-bred poultry is the primary purpose of the Nebraska National Egg Laying and Breeding Contest. Data on the cost of egg production and on the problems of poultry breeding will also be secured.


On A New Species Of Otter From Nebraska, Myron Harmon Swenk Jan 1918

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 …


Recent Lamb Feeding Investigations At The University Of Nebraska, H. J. Gramlich Oct 1917

Recent Lamb Feeding Investigations At The University Of Nebraska, H. J. Gramlich

Department of Animal Science: Faculty Publications

During the past several years considerable experimental work has been performed at the University of Nebraska in fattening western lambs. The attractiveness of fattening lambs at prices existing during a series of recent years has caused a material increase in the interest in this work, and we have felt justified in experimenting rather extensively to ascertain the most satisfactory combination of feeds to use under our Nebraska conditions.
The objects in view have been chiefly to ascertain the most satisfactory rations where corn and alfalfa hay constituted the basal feeds. We have used these two feeds extensively because of the …


Cooling Tanks And Milk Houses As Factors In Cream Improvement, J. H. Frandsen May 1917

Cooling Tanks And Milk Houses As Factors In Cream Improvement, J. H. Frandsen

Nebraska Agricultural Experiment Station: Historical Circulars

The dairymen of this country have suffered enormous losses due to the lower price received for poor butter. The present need is for a survey of the situation that shall result in a thoro understanding and cooperation of cream producers, creamery men, legislators, and educators.


Pork Production In Nebraska, E. A. Burnett May 1917

Pork Production In Nebraska, E. A. Burnett

Nebraska Agricultural Experiment Station: Historical Circulars

This circular discusses a variety of recommendations to produce pork profitably during World War I.


On A New Subspecies Of Porcupine From Nebraska, Myron H. Swenk Jan 1916

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, …


The Destruction Of The Vitality Of Cysticercus Bovis By Freezing, Brayton H. Ransom Sep 1914

The Destruction Of The Vitality Of Cysticercus Bovis By Freezing, Brayton H. Ransom

Harold W. Manter Laboratory of Parasitology: Library Materials

First two paragraphs:

The question as to the length of time Cysticercus bovis may survive after the death of its host has been quite definitely settled by the researches of Perroncito, Zschocke, Ostertag and others. Perroncito (1877) found that the cysticerci in an artificially infested calf were all dead fourteen days after the slaughter of the animal. However, Zschocke (1896) succeeded in infesting the human subject with a tapeworm by feeding five cysticerci from beef kept from fourteen to sixteen days after slaughter. No infestation followed the swallowing of five cysticerci from beef kept twenty-one days after slaughter. Ostertag (1897) …


Dr. Nott's Theory Of Insect Causation Of Disease, William A. Riley Sep 1914

Dr. Nott's Theory Of Insect Causation Of Disease, William A. Riley

Harold W. Manter Laboratory of Parasitology: Library Materials

Excerpt:

The danger in using isolated sentences from an article as a basis for interpreting the author's theories, is generally recognized, but sometimes the most careful workers fall into the trap. Once the mistaken interpretation is published, it may be copied over and over again until it rises to the dignity of a dogma.

A striking illustration is afforded by the practical unanimity with which writers on the subject of insects and disease credit Dr. Josiah Nott with being the earliest to formulate definitely the theory of mosquito transmission of yellow fever.

Nuttall, in his classic monograph On the Role …


A Plea For The Protection Of Our Birds, Lawrence Bruner Oct 1908

A Plea For The Protection Of Our Birds, Lawrence Bruner

Department of Entomology: Faculty Publications

The fact that insect depredations are increasing in extent each succeeding year makes it plain to us that something must be done to prevent it, and that quickly. We have found to our sorrow that, although we are continually making increased efforts to destroy these pests, our efforts avail but little and the destruction of our crops goes on. What, then, is to be done? How can we be released from this ever-increasing struggle for existence? The answer is plain. Heed the advice of the Naturalist who has made a study of the life-histories of the various other living creatures …


A Preliminary Review Of The Birds Of Nebraska With Synopses, Lawrence Bruner, Robert H. Wolcott, Myron H. Swenk Jan 1903

A Preliminary Review Of The Birds Of Nebraska With Synopses, Lawrence Bruner, Robert H. Wolcott, Myron H. Swenk

Papers in Ornithology

In 1896, Prof. Bruner published his list entitled "Some Notes on Nebraska Birds." As a working basis for the study of the ornithology of the state it has proven invaluable and it has also been greatly in demand by people not ornithologists, who desired to "know something about our birds." That edition was exhausted some time ago and its author has been frequently urged to publish another. However, the organization of the Nebraska Ornithologists' Union and the development of ornithology in the University has led to such a rapid increase in our knowledge in the past five years that it …


Article Xxii.-A New Genus Of Ground Sloth From The Pleistocene Of Nebraska, Barnum Brown Jan 1903

Article Xxii.-A New Genus Of Ground Sloth From The Pleistocene Of Nebraska, Barnum Brown

University of Nebraska State Museum: Mammalogy Papers

This genus is founded on a nearly perfect skull and lower jaw in the American Museum collections (No. 2780), with associated skeletal material including five cervical vertebrae, tibia, fibula, calcaneum, astragalus, lunar, middle digit of manus, and ribs, found by the Expedition of 1897 near Hay Spring, Nebraska. Professor Henry F. Osborn has placed this material in the writer's hands for description.

Note On Taenia Confusa, Henry B. Ward Aug 1897

Note On Taenia Confusa, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

About a year ago I described in the Western Medical Review (Vol. I. pp. 35, 36) a new tape-worm under the name of Taenia confusa. Only two specimens of the form were available at that time and I have not been successful in obtaining others since then. During the past 'year, one of the students in the Zoological Laboratory of the University of Nebraska has been conducting a careful investigation of this form and one specimen has been entirely sacrificed to that purpose, In advance of the publication of his thesis it seems that I should make a short explanation …


Zoology In The High School Curriculum, Henry B. Ward Aug 1897

Zoology In The High School Curriculum, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

A long time has elapsed since Bacon gave to the world the sound advice that “ we should accustom ourselves to things themselves.” Little by little this idea has gained ground, until now it is recognized as a general principle in every grade of educational work and in widely separated departments of study that contact with concrete objects is far more inspiring and thought-producing than the mere scanning of black marks on a white page. So far as natural science is concerned, the varied training which it affords has been abundantly discussed before this association and elsewhere. To be sure, …


Studies On Nebraska Parasites, Henry B. Ward Aug 1897

Studies On Nebraska Parasites, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

The intimate relations in which domestic animals stand to man have always made the transfer of parasites from the one to the other a matter of much greater probability than exists between man and the other forms of animal life. It is but natural that the most common species of human tapeworm come to man from his two chief sources of animal food-beef and pork. The chances of accidental infection, however, are evidently much greater in the case of those forms that are intimately associated with man, and hence clearly greatest in those he holds as household pets,the dog and …


Animal Parasites Of Nebraska, Henry B. Ward Aug 1896

Animal Parasites Of Nebraska, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

The report submitted this year consists of two main portions: the first a short study on the numerical frequence of parasites among the dog, cat, and chickens of Nebraska, and the second of several brief accounts of new and important parasites discovered within the state since the publication of the last report.


A Biological Examination Of Lake Michigan In The Traverse Bay Region, Henry B. Ward Aug 1896

A Biological Examination Of Lake Michigan In The Traverse Bay Region, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

During the summer of 1893 the Michigan Fish Commission entered upon a biological study of the Great Lakes by maintaining a party on Lake St. Clair. In the report of that two months, written by the director of the laboratory, Professor J. E. Reighard, are given in full the reasons which led to the inception of the undertaking and the aims which its promoters held in view. A study of the life of the lake in all its manifold interrelations and especially of those factors which bore upon the welfare of the food fishes in general and the young whitefish …


A New Human Tapeworm (Taenia Confusa N. Sp.), An Entozoon, Probably Of Order Cestoidea, Henry B. Ward Jan 1896

A New Human Tapeworm (Taenia Confusa N. Sp.), An Entozoon, Probably Of Order Cestoidea, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

Somewhat more than a year ago a tapeworm was sent me which at first sight appeared decidedly unlike either Taenia saginata or Taenia solium. It showed the slender form and more delicate appearance of the latter, but was in length of segments even decidedly larger than the former species. Some notes were made at the time, and then, on account of pressure in other directions, laid aside to await opportunity for further study. This winter I received a second specimen which at once recalled the first, and on comparison was seen to be identical with it. A series of …


The Food Supply Of The Great Lakes; And Some Experiments On Its Amount And Distribution, Henry B. Ward Jan 1896

The Food Supply Of The Great Lakes; And Some Experiments On Its Amount And Distribution, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

The subject of agriculture has received for many years the closest attention of scientific workers. Not only the character of the different products, their food value for different uses and in connection with the raising of different kinds of stock ; but also the value of the soil, the use of each element in it, the exact relation of each individual particle in the entire chain of biological relations from the unorganized matter to the saleable beef or pork, has received from the experiment stations of the country the most careful study. Every one of the pests, of the enemies …


Some Notes On Nebraska Birds: A List Of The Species And Subspecies Found In The State, With Notes On Their Distribution, Food-Habits, Etc., Lawrence Bruner Jan 1896

Some Notes On Nebraska Birds: A List Of The Species And Subspecies Found In The State, With Notes On Their Distribution, Food-Habits, Etc., Lawrence Bruner

Papers in Ornithology

For upwards of twenty-five years the writer has taken an interest in our birds and made notes relative to their abundance, migrations, nesting, food-habits, etc., simply for personal gratification.

About two years ago, during a conversation in which the relation of birds to horticulture incidentally arose, Professor F. W. Taylor suggested the advisability of devoting a portion of a succeeding annual report to our Nebraska birds. With this object in view both the professor and the writer broached the matter to other members of the Society. Several at once not only became interested in the matter, but suggested its early …


On Distoma Felineum Riv. In The United States And On The Value Of Measurements In Specific Determinations Among The Distomes, Henry B. Ward Aug 1895

On Distoma Felineum Riv. In The United States And On The Value Of Measurements In Specific Determinations Among The Distomes, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

The distomes of cats have received special attention of late in the two papers of Braun (94) and Stiles and Hassall (94). The latter authors give a most admirable account of our present knowledge of a dozen allied forms, and record two, D. albidum and D. complexum n. sp., as found in cats in the United States. During the past year I have examined the cats killed at this laboratory, and have found neither of the forms recorded from the east. Distoma felineum, however, which Stiles and Hassall did not find. and which has not been reported hitherto for …
