Swine Erysipelas, L. Van Es, C. B. Mcgrath Aug 1936

Swine Erysipelas, L. Van Es, C. B. Mcgrath

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Because of the more or less frequent occurrence of swine erysipelas on Nebraska farms it seemed proper that information on this subject be made available in the form of a Station publication, especially written to serve as a reference for veterinarians, who naturally are first appealed to when an as yet relatively strange disease appears among a herd of swine. Hence the text is written in a technical form for the sake of precision. In the preparation of the text the literature of countries in which for many years the disease has constituted a permanent problem has been freely consulted. …


White Scours Of Calves, L. Van Es May 1933

White Scours Of Calves, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

It becomes possible to understand some of the reasons for the occurrence of disorders among the newborn of animals kept under the usual conditions imposed by domestication. Among these, the subject of this circular, White Scours in Calves, occupies a prominent place.


A General Discussion Of Trichinella Spiralis (Owen), An Investigation Of Infection Of The Brown Rat, And A Life History Study Of The Parasite In The White Rat, Carl A. Johnson Jan 1931

A General Discussion Of Trichinella Spiralis (Owen), An Investigation Of Infection Of The Brown Rat, And A Life History Study Of The Parasite In The White Rat, Carl A. Johnson

Electronic Theses and Dissertations

The purpose of this treatise is threefold: first, to present a general discussion of Trichinella spiralis,; second, to present the results of an investigation of infection with trichinae of 100 brown rats; and third, to present the results of infecting white rats under laboratory conditions.


The Incidence Of Avian Tuberculosis In Mammals Other Than Swine, L. Van Es, H. M. Martin Aug 1930

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

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

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 …


Swine Sanitation, L. Van Es Mar 1930

Swine Sanitation, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

From the very beginning of Nebraska's agricultural development its farmers have recognized that the production of swine must of necessity accompany the growing of corn. The latter, one of the state's most important staples, cannot be marketed in a more economical manner than after having been transformed into pork, bacon, and lard. As a result the state has for many years maintained a rather dense swine population mainly divided into large herds kept on relatively small areas of land. This density of population, as well as certain practices in management and selective breeding, has brought about conditions favorable for the …


Bovine Tuberculosis, L. Van Es Jan 1929

Bovine Tuberculosis, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

The development of the present-day knowledge of the tuberculoses of animals is so intimately associated with that pertaining to the human form of the disease that the latter needs to be included in the historical considerations, without which it would be difficult to view any phase of the subject in a comprehensive manner.


An Inquiry Into The Cause Of The Increase Of Tuberculosis Of Swine, L. Van Es, H. M. Martin Feb 1925

An Inquiry Into The Cause Of The Increase Of Tuberculosis Of Swine, L. Van Es, H. M. Martin

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The great increase in the number of swine found to be tuberculous presented a problem, the solution of which appeared to be desirable before adequate control measures could be devised or recommended. In the hope that a solution of the problem may be found this station undertook an investigation and attempted by experimental inquiry to determine the infection type of the tuberculosis associated with the animals which constituted the bulk of the retentions. In view of the apparent increased incidence and spread of tuberculosis among poultry in a large hog raising section, of which Nebraska forms a part, the experimental …


Bovine Tuberculosis, L. Van Es Feb 1924

Bovine Tuberculosis, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

Tuberculosis affects all species of domestic mammals although with different degrees of intensity and frequency. Cattle and swine furnish the greatest number of cases.


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

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

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 Immunizing Value Of Commercial Vaccines And Bacterins Against Hemorrhagic Septicemia, L. Van Es, H. M. Martin Jun 1920

The Immunizing Value Of Commercial Vaccines And Bacterins Against Hemorrhagic Septicemia, L. Van Es, H. M. Martin

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

In the course of certain studies having to do with hemorrhagic septicemia, we were particularly struck with the difficulties which we encountered in the immunization of susceptible laboratory animals (rabbits). This difficulty in no small degree excited our curiosity regarding the immunizing value of the considerable number of "Hemorrhagic Septicemia bacterins and vaccines" which during recent years have become such a prominent article of commerce. In the hope of securing some information relative to the immunizing value of the agents mentioned, we undertook a series of experiments in which the immunity of the bacterin and vaccine injected laboratory animals was …


The Value Of Commercial Vaccines And Bacterins Against Fowl Cholera, L. Van Es, H. M. Martin Jun 1920

The Value Of Commercial Vaccines And Bacterins Against Fowl Cholera, L. Van Es, H. M. Martin

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

A great prevalence of the disease known as fowl cholera has naturally stimulated an interest in possible means of prevention and especially in those which may bring about a more or less lasting immunity. Vaccines which were favorably reported by some failed utterly in the hands of others, so that on the whole no substantial advantage has been gained. Vaccines and bacterins are nevertheless constantly urged on poultry owners confronted with disease and the Experiment Station is frequently called upon to give an opinion on their value or to recommend any special preparation. In order to comply with those demands …


The Parasitic Worms Of Man And The Domestic Animals, Henry B. Ward Aug 1895

The Parasitic Worms Of Man And The Domestic Animals, Henry B. Ward

Studies from the Zoological Laboratory: The University of Nebraska

This article has been written for the general information of those engaged either on a large or on a small scale in stock raising in our own state particularly, and, while not intended to be a complete treatise on the subject, it includes references to those parasites which seem to be the most important or most likely to be found within our borders. The parasites of cattle, sheep, horse, hog, dog, cat, and man, which have many species in common, form the subject of this paper. The parasites of domestic fowl are, however, quite different from those considered here and …


Report Of The Zoologist, Henry B. Ward Jan 1895

Report Of The Zoologist, Henry B. Ward

Studies from the Zoological Laboratory: The University of Nebraska

In the report of last year was given a full summary of the present state of our knowledge concerning the parasites of man and the domestic animals. It is the intention of the following pages to review the parasitic fauna of the state of Nebraska so far as it is definitely determined, and also to include a list of some species reported but not accurately identified. The second section of this report presents a brief description of some important parasites not included in the group of worms, and hence not mentioned in last year's report. I shall omit all parasites, …
