Growth In Weight Of Selected Organs, Tissues And Systems In The Pig, William J. Loeffel, Robert M. Koch
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
As a result of investigations at the Nebraska Agricultural Experiment Station in 1929, 1930 and 1931 to determine the effect of weight and degree of fatness of the pork carcass upon the quality and palatability of the meat, 40 pigs were slaughtered, five each at the approximate live weights of 70, 80, 90, 100, 115, 135, 160, and 180 kg. This corresponds to carcass weights ranging from 50 to 150 kg. The results of the meat investigations and feedlot data were reported elsewhere (Loeffel et al.,1943). This study reports data relative to the weight of selected tissues and organs, as …

Forty Years Of Dairy Cattle Breeding At The North Platte Experiment Station, Mogens Plum, Myron G.A. Rumery
Forty Years Of Dairy Cattle Breeding At The North Platte Experiment Station, Mogens Plum, Myron G.A. Rumery
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
In 1913 the Nebraska Legislature appropriated $17,500 to establish a Dairy Department at the North Platte Experiment Station. The department's herd was to be used in demonstrating management and breeding practices and as a source of breeding stock. Since the North Platte herd was started, research in the field of animal breeding has developed new concepts in many phases of dairy cattle breeding and selection. The purpose of the present study is to analyze the progress made under a system of dairy cattle breeding and selection carried out according to the principles that dominated 40 years ago. The results of …
Pig Typhus (Salmonellosis Suis), L. Van Es
Pig Typhus (Salmonellosis Suis), L. Van Es
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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.
The Effects Of Penicillin On E. Rhusiopathiae Infected Pigeons, L. Van Es, J. F. Olney, I. C. Blore
The Effects Of Penicillin On E. Rhusiopathiae Infected Pigeons, L. Van Es, J. F. Olney, I. C. Blore
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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.
Swine Erysipelas Infection In Man, L. Van Es
Swine Erysipelas Infection In Man, L. Van Es
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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.

Vegetative Composition And Grazing Capacity Of A Typical Area Of Nebraska Sandhill Range Land, A. L. Frolik, W. O. Shepherd
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The sandhill area of Nebraska occupies approximately 20,000 square miles of the central portion of the state. Being unadapted to cultivation, the land is for the most part still covered with native vegetation. It is utilized primarily for the production of livestock, chiefly cattle. During the period 1931 to 1938 the sandhills carried annually an average of 1,041,000 cattle, which amounted to 31 per cent of the total number in the state. The management practices used in the Nebraska sandhills have gained national recognition as a good example of range conservation in the United States. The purpose of this study …

Studies Of Rickets In Swine, William J. Loeffel, Ray R. Thalman, F. C. Olson, F. A. Olson
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
During the years 1925 to 1929 inclusive, the Nebraska Agricultural Experiment Station carried on a series of four experiments to study the importance of the antirachitic factors in the nutrition of swine. Vitamin D as obtained from cod-liver oil and the radiant-energy factor of sunlight were the sources of the antirachitic factors that received primary consideration. Emphasis was placed upon the study of the symptoms and lesions produced in pigs fed a rickets-producing ration.
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
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
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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.
Studies On The Ascaris Lumbricoides, H. M. Martin
Studies On The Ascaris Lumbricoides, H. M. Martin
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The Ascaris lumbricoides, in one phase or another, has attracted the attention of parasitologists for many years, and during the last decade this parasite has been studied by a large number of investigators. The recent observations have been, to a great extent, directed along one line, the study of its life history. These investigators have established two important points: (a) That the life history of Ascaris is more complex than was supposed, as it has been found that a vasculo-pulmonary circuit of the larvae is necessary before they settle down in the intestine, where they develop to the adult …

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.
