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 …

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.

The Prevention Of Anthrax, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

Anthrax is a communicable disease, caused by a specific germ known as the anthrax bacillus. Cattle, sheep, horses and swine are susceptible to the infection and in variable degree this susceptibility is shared by other animal species, including man.

The Gizzard Worm And Its Transmission To Chickens In Hawaii, Joseph E. Alicata

Harold W. Manter Laboratory of Parasitology: Library Materials

Gizzard-worms of poultry, Cheiloapirura hamulosa, are nematodes occurring in the gizzards of chickens and turkeys.

Summary and Conclusions

Previous to this report the carriers for the gizzard-worm in Hawaii were unknown. Recent investigations by the writer have shown that the flour beetle, Tenebroides nana, and the sand hopper, Orchestia platensis, collected from poultry farms in the Territory of Hawaii have been found naturally infested with the infective larvae of the poultry gizzard-worm, Cheilospirura hamulosa. Out of 8 laboratory-raised chickens to which there were fed about 2,300 grasshoppers that had been collected in an endemic gizzard-worm area, …

The Immunizing Value Of Commercial Hemorrhagic Septicemia Aggressins, L. Van Es, J. F. Olney

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In 1924, Gochenour published the results of certain experiments which tended to show that what he regarded as a specific aggressin possessed an immunizing value against hemorrhagic septicemia. The aggressin he prepared, by the use of a highly virulent strain of Bacillus bipolaris, was described as having adequately protected seven bovine yearlings against inoculations with the same organism which, when injected into four yearlings, used as virus controls, proved fatal to them. Soon after, if not simultaneously with, the publication of the Gochenour articles, hemorrhagic septicemia aggressin was placed on the market and apparently has since then been sold …

Experiments On The Infectivity For Healthy Calves Of Bovine Tubercle Bacilli Discharged In Dung Upon Pasture, E. C. G. Maddock

Michigan Bovine Tuberculosis Bibliography and Database

In a previous paper (Maddock, 1934), it has been shown that healthy calves may be infected with bovine tubercle bacilli when grazed upon pasture infected at intervals with emulsions of the virulent organisms. These infections were designedly heavy, and it was felt that this orientating experiment should be followed by one in which pasture infection was secured in a way more closely approximating to the natural.
Three calves surviving from the previous experiment had reacted strongly to the double intradermal tuberculin test. Microscopic examination of the dung of these animals failed to show the presence of acid-fast bacilli, but to …

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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. …

Some Monogenetic Trematodes From The Galapagos Islands And The Neighboring Pacific, Frank Grose Meserve

School of Biological Sciences: Dissertations, Theses, and Student Research

Introduction

Trematodes are parasitic, unsegmented, flattened (rarely cylindrical) worms. They have ventral, anterior, posterior or median attachment organs. The sense organs are poorly developed. The mouth is terminal or ventral and subterminal. The intestine is usually forked with or without lateral branches. The animals, with few exceptions, are hermaphroditic. The ovary is usually single. They have one, two, or more testes. The development is direct with only one host in the ectoparasitic Monogenea and indirect in the Digenea which have two or more hosts. The digenetic trematodes usually parasitize vertebrates which serve as their primary hosts and invertebrates (Mollusca) which …

Further Studies On The Survival Time Of The Bovine Tubercle Bacillus In Soil, Soil And Dung, In Dung And On Grass, With Experiments On Feeding Guinea-Pigs And Calves On Grass Artificially Infected With Bovine Tubercle Bacilli, E. C. G. Maddock

Michigan Bovine Tuberculosis Bibliography and Database

IN a previous paper (Maddock, 1933) it was reported that when soil, soil and dung mixtures and dung were infected by adding fine emulsions of bovine tubercular material, virulent tubercle bacilli could be recovered after 178 days' exposure under field conditions. The experiments reported in the aforesaid paper were carried out in 1931, but it was felt that weight would be added to the results if the experiments could be repeated in a year of differing weather conditions.

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.

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. 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.

The Viability Of B. Tuberculosis (Bovinus) On Pasture Land, In Stored Faeces And In Liquid Manure, R. Stenhouse Williams, W. A. Hoy

Michigan Bovine Tuberculosis Bibliography and Database

The object of these experiments was to determine the length of time during which B. tuberculosis in cow's faeces remain alive and virulent on pasture land in the south of England. The method of testing for living B. tuberculosis is given in Appendix II.

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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

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 …

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

Nebraska Agricultural Experiment Station: Historical Circulars

Successful animal husbandry is fundamentally dependent on the efficient reproduction and preservation of young stock. Not only are losses among the latter a prolific source of direct economic damage, but they also tend to create an equally serious disadvantage of a more indirect nature. Losses of young animals, unless a reduction of our live stock population can be tolerated, necessitate the setting aside of a larger number of females for purely reproductive purposes than would be required if such losses were not a factor.

On The Nature And Cause Of "The Walking Disease" Of Northwestern Nebraska (Necrobiosis Et Cirrhosis Hepatis Enzootica), L. Van Es, L. R. Cantwell, H. M. Martin, J. Kramer

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The "walking disease" of Northwestern Nebraska is essentially an enzootic necrobiosis and cirrhosis of the liver due to a toxic agent and does not materially differ from similar disorders occurring in other regions or countries. The disease affects horses and cattle but it is most commonly encountered in the former. The disease in all its clinical and pathological manifestations may be reproduced with the utmost fidelity by the feeding with plants of Senecio riddellii.

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.

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 in 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 …

Tuberculosis Of Swine, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

The tuberculosis of swine constitutes a definite and very interesting section of the general problem of the tuberculoses of warm-blooded animals. No one section of this general tuberculosis problem can be adequately solved without regard to all the other sections into which it may be divided. The disease in swine is perhaps the most outstanding example which illustrates this point. This animal, extremely susceptible to tuberculous disease, but without a type of infection specifically its own, derives its infection by contact with any of the types of tuberculosis of warm-blooded animals.

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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 …

These Fifty Years: A History Of The College Of Agriculture Of The University Of Nebraska, R. P. Crawford

Nebraska Agricultural Experiment Station: Historical Circulars

It seems especially appropriate at this time to publish a history of the College of Agriculture of the University of Nebraska. The year 1922 marked the fiftieth anniversary of the formal establishment of the college by the Board of Regents, while the year 1924 marked the fiftieth anniversary of the enrollment of the first students in agricultural subjects. It is hoped and intended that this little volume shall preserve for the future much valuable material that would otherwise soon be forgotten.

Bovine Tuberculosis, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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 …
