Leaflet No 1002 - Swine Paratyphoid (Salmonellosis Necrotic Enteritis), C R. Toop

Bulletins 1 - 2999

Paratyphoid is an infectious disease of pigs which is likely to make it appearance wherever pig raising is practised.

It may occur in an acute septicaemic form which is often rapidly fatal and accompanied by serious mortality and in a sub-acute or chronic form known as necrotic enteritis which is characterised by unthriftiness and scouring. The out breaks occurring in Western Australia are principally of the acute type and they are usually associated with the introduction of pigs from saleyards.

Pig Typhus (Salmonellosis Suis), L. Van Es

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Salmonellosis suis or pig typhus, also designated as pig typhoid, infectious necrotic enteritis, or "necro," is an infectious disease among young pigs. It constitutes a major factor in the mortality of juvenile swine, and as such must be regarded as a more or less perennial hazard in swine production. Infectious necrotic enteritis caused by Salmonella suipestifer is the subject of the present publication.

Vitamins For Poultry, F. E. Mussehl, C. W. Ackerson

Nebraska Agricultural Experiment Station: Historical Circulars

Vitamins are chemical substances essential for the maintenance of life, growth, and reproduction. Their effects are out of proportion to the relatively small amounts required. Fortunately, most of these essentials are widely distributed in nature, and an adequate ration can nearly always be provided by using logical combinations of common feedstuffs. Under certain conditions, however, the use of vitamin-containing concentrates may be desirable. In planning practical rations, it should be recognized that the plant leaf is the source of most vitamins. Milk and meat products make important vitamin contributions to the diet in addition to their proteins and minerals. Direct …

Studies On The Validity Of Swine Erysipelas Culture-Vaccines, L. Van Es, J. F. Olney, I. C. Blore

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In countries where vaccination against swine erysipelas has been practiced during the last half century, there is a consensus among veterinarians that the best results are obtained when the live culture-vaccine is not only fresh and highly virulent but is endowed also with a good capacity for growth on artificial culture media. Apparently avirulent culture-vaccines are apt to engender only a transitory immunity or fail altogether. The problem presented by undesirable culture-vaccines was deemed to be of such importance to the swine industry that this Station undertook a series of experiments, to determine what influences might be accountable for the …

A Study Of The Renal Vascular Supply In The Domestic Cat, Elizabeth Rosen

Bachelors’ Theses

Studies on the normal and abnormal vascularization of the renal vessels in the domestic cat (felis domestica) indicate the frequency of anomalies that occur, but in most of the studies it is the inferior vena cava that is most often recorded. Among the occasional references to several renal veins or arteries we have Huntington and McClure, Elmer Butler, Gaylord Bates, William Darrach, and C.H. Fortune. Yet no study seems to have been made of individuals of any particular class. A superficial observation seems to indicate a large number of cats used in the laboratory had multiple renal veins. Hence a …

The Effects Of Penicillin On E. Rhusiopathiae Infected Pigeons, L. Van Es, J. F. Olney, I. C. Blore

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Advantage was taken of an opportunity to study the effects of penicillin on Erysipelothrix rhusiopathiae, the causative organism of swine erysipelas. Owing to the fact that swine cannot readily be infected with erysipelas by artificial methods, pigeons which are highly susceptible to the disease, were selected to serve as experimental animals. It was the purpose of these studies to ascertain whether or not the swine erysipelas bacillus is sensitive to the drug and incidentally to determine the possibility of finding application of penicillin in the treatment of swine.

Collected Observations Pertaining To Hog Cholera, L. Van Es, J. F. Olney

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This bulletin reports on the following: (1) the possible role of Salmonella suipestifer in failed vaccinations (vaccination breaks); (2) excessive serum dosages as a cause of vaccination breaks; (3) experiments with crystal-violet hog cholera vaccine and (4) hog cholera vaccine of tissue origin, and (5) phenolized hog cholera virus as a possible vehicle for pathogenic contaminants.

External Parasites Of Poultry And Methods For Their Control, O. S. Bare

Nebraska Agricultural Experiment Station: Historical Circulars

External parasites cause severe losses to Nebraska poultry producers each year, and in many cases may be the deciding factor between success and failure. Under present circumstances, when maximum production is essential, prompt and effective measures must be taken to hold these saboteurs in check.

A Study Of The Digestive System In The Sparrow (Passer Domesticus), Henry Joseph Wisniewski

Bachelors’ Theses

The digestive tube proper of the Sparrow beings with the Oesophagus. This is a soft tubular organ which serves to convey food rapidly from the pharynx to the stomach. It extends along the median ventral margin of the neck lying dorsal to or to one side of the trachea. Posteriorly, at the base of the neck and shortly in front of the sternum it broadens slightly and gives rise to a dilated region of the oesophagus, namely the Crop, "whose secretion serves to moisten the food or even to initiate digestion." In larger birds as in the pigeon, the crop …

Swine Erysipelas Infection In Man, L. Van Es

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The preceding decade witnessed the introduction and spread within this state of a hitherto uncommon disease of swine. This disorder, swine erysipelas, has gradually become disseminated throughout Nebraska's swine population until it has developed into a major problem of preventive veterinary medicine. Its appearance, furthermore, added another to our list of animal maladies which are communicable to man. The latter consideration may serve as warrant to review what is known about the part played by swine erysipelas as a human disease, to describe its more salient features and to examine them from epidemiological, clinical, pathological and prophylactic viewpoints.

Swine Erysipelas. Revised Edition Of Research Bulletin 84, 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. …

An Inquiry Into The Influence Of Environment On The Incidence Of Poultry Diseases, L. Van Es, J. F. Olney

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The principal purpose of the investigation reported here was to evaluate, if possible, hygienic measures, and in addition to gather whatever information might become available pertaining to the relation of certain disorders to a given poultry population after its exposure to their specific etiologic factors. The experiments were conducted on a piece of ground upon which poultry had not been maintained for many years, if ever.

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

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 …

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 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 …

The Lungs And Respiration In The Frog, Peter P. Strassburg

Bachelors’ Theses

In a wide sense, respiration is sometimes defined as the gaseous exchange constantly taking place between an organism and its environment. Essentially it is concerned with the intake of oxygen and the output of carbon dioxide but it also includes any other gas exchange that might occur. Small organisms take oxygen directly from the air or from the watery medium surrounding them into all parts of their structures. They also give off carbon dioxide from all their parts directly into the surrounding medium. They can do this successfully because they are small enough to have every cell in direct or …

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 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 …

The Anatomy Of The Oyster, M.J. Rohlinger

Bachelors’ Theses

The phylum Mollusca manifests the following characteristics: bilateral symmetry; three primary germ layers; free-living and sessile; marine and fresh-water; a shell modified to form either a bivalve or a univalve which gives an appearance of segmentation due to rings of growth or arrangement of certain parts of the shell as is seen in the class Amphineura, this is only apparent metamerism because the Mollusca are considered to be unsegmented animals; a coelom poorly developed; a foot; a mantle cavity; well developed digestive, circulatory, excretory, and reproductive systems. When one inspects a Chiton, an oyster, a snail, an octopus, or a …

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 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 …
