Javma37-43 Anthrax In Swine, L. Van Es Jan 1937

Javma37-43 Anthrax In Swine, L. Van Es

University of Nebraska-Lincoln Extension: Historical Materials

Anthrax is not commonly considered so important a menace to swine as it is to other forms of live stock, in which the disease is apt to declare itself with terrifying severity. In comparison with the marked mortality frequently observed in cattle, the tangible losses caused by anthrax in swine seem negligible. As recent as 25 years ago, there still were observers who sincerely doubted the occurrence of the disease in hogs and this opinion found some support in the many reported failures to induce the infection in that animal species by artificial methods.

Crow-Waterfowl Relationships Based On Preliminary Studies On Canadian Breeding Grounds, E. R. Kalmbach Jan 1937

Crow-Waterfowl Relationships Based On Preliminary Studies On Canadian Breeding Grounds, E. R. Kalmbach

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

With the object of obtaining a current insight into the relationship of crows to waterfowl on their breeding grounds, a study was inaugurated in the spring of 1934 and continued through the nesting season of that and the following year. As originally planned, it called for field studies both in Canada and in the northern United States, but drought conditions had so drastically reduced the breeding population of ducks within our borders by the spring of 1934 that, after a futile effort to locate suitable areas in this country, plans were changed and the studies were restricted to Canadian areas …


Diseases Of Upland Game Birds, J. E. Shillinger, L. C. Morley Jan 1937

Diseases Of Upland Game Birds, J. E. Shillinger, L. C. Morley

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Until recently the diseases of upland game birds received comparatively little specific study, except in a few outbreaks in which serious losses were observed. Though highly destructive, many of these outbreaks were of such short duration that the investigations undertaken were chiefly to learn the cause of death and usually were discontinued when losses were no longer noticeable. It has become increasingly evident, however, that every year great numbers of game birds die of disease, the decreases in their numbers frequently occurring in sections closed to hunting, even though food, cover, and other environmental conditions appear ideal. The disease problems …


The Gizzard Worm And Its Transmission To Chickens In Hawaii, Joseph E. Alicata Jan 1937

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, …


Local Bird Refuges, W. L. Mcatee Jan 1937

Local Bird Refuges, W. L. Mcatee

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Birds appeal strongly to the interests and affections of mankind. Not only do they charm by their graceful forms, harmonious colors, sprightly actions, and usually pleasing notes, but they have an even more important claim upon our esteem because of their great economic value.

Birds feed upon practically all insect pests. They are voracious, are able .to move freely from place to place, and exert a steady influence in keeping down the swelling tide of insect life.

For economic as well as for esthetic reasons, therefore, an effort should be made to attract and protect birds and to increase their …


Weeds In Sacramento County Of California, Ross Clover Jan 1937

Weeds In Sacramento County Of California, Ross Clover

University of the Pacific Theses and Dissertations

Sacramento County has many types of Agriculture and many weed pests which compete with the crops. Stock may be poisoned by certain weeds and weeds may also act as hosts for fungus diseases, virus diseases and insect pests of cultivated crops. Many plants may be weeds in one locality and harmless or beneficial in other parts. The author has made a thorough study of the country's agriculture and its weeds. Latest control practices were also studied.

Bulletin No. 275 - Types Of Farming In Utah, Marion Clawson, Walter U. Fuhriman, George T. Blanch, W. Preston Thomas Nov 1936

Bulletin No. 275 - Types Of Farming In Utah, Marion Clawson, Walter U. Fuhriman, George T. Blanch, W. Preston Thomas

UAES Bulletins

A large portion of the agriculture of Utah, outside of the desert range areas, is characteristically heterogeneous rather than homogeneous in character. Marked differences in size of farm, in crops grown, in livestock kept, in yields, and in farm organization occur within short distances. This diversity is due in large measure to differences in soil, elevation, topography, and other physical features and to climatic characteristics such as amount, kind, and distribution of precipitation and length of growing season. The physical and climatic features are the chief determinants of the amount of water potentially available for the irrigation of the crop …

Shell Repair In Polygyra Texasiana, Elmer P. Cheatum Nov 1936

Shell Repair In Polygyra Texasiana, Elmer P. Cheatum

Field and Laboratory

It has long been known, on the basis of field observations and laboratory experiments, that snails and clams are able to repair breaks in their shells. However, with the exception of Andrews' ('34, '35) excellent work on shell-repair of West Indian gastropoda, and Daniel's ('12) studies, practically all observations have been made upon European mollusks.


Bulletin No. 274 - Influence Of Rotation And Manure On The Nitrogen, Phosphorus, And Carbon Of The Soil, J. E. Greaves, C. T. Hirst Oct 1936

Bulletin No. 274 - Influence Of Rotation And Manure On The Nitrogen, Phosphorus, And Carbon Of The Soil, J. E. Greaves, C. T. Hirst

UAES Bulletins

All agricultural plants require carbon, hydrogen, oxygen, nitrogen, calcium, potassium, magnesium, sulfur, phosphorus, iron, and probably traces of other elements for their normal growth and fruition. The growth of farm crops is dependent upon an available supply of these elements, and the extent of growth is governed by the one present and available in least quantity in proportion to the plant's needs. Of the essential elements, all plants secure two (carbon and oxygen) from the air, one (hydrogen) from the water, and the others from the soil. Most soils contain sufficient plant nutrients for normal plant production, with the exception …

An Interpretive Study Of Some Kentucky Biologists, Rachel Winstead Aug 1936

An Interpretive Study Of Some Kentucky Biologists, Rachel Winstead

Masters Theses & Specialist Projects

This study was undertaken with the idea of bringing together information concerning some of the most important Kentuckians who have made contributions to the biological sciences. In order that we may better understand and appreciate the work done by these men, it was thought best to give a brief discussion of the major periods in the history of biological development. An attempt will be made to interpret the contributions of the men discussed, according to the period in which they lived. Only a sufficient number of men are discussed in each epoch to give a correct picture of the trends …


The Effects Of Vitamins "A" & "D" Deficient Diets On Crayfish, Joseph Hale Aug 1936

The Effects Of Vitamins "A" & "D" Deficient Diets On Crayfish, Joseph Hale

Masters Theses & Specialist Projects

The literature on vitamins shows that the greater number of the studies made of vitamin "A" and "D" deficient diets have been confined to their efforts on the vertebrates. Only a few controlled experiments have been conducted to determine the effects of vitamin "A" and "D" deficient diets on the invertebrates.

The purpose of this investigation was to determine the effects of vitamin "A" and "D" deficient diets on crayfish.


Reports From "Drought Front" Tell State Or Vegetation, J. E. Weaver Jul 1936

Reports From "Drought Front" Tell State Or Vegetation, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Development of the natural prairie vegetation is an excellent indicator of the intensity of drought. The extreme drought of 1934 left many bare areas in the grasslands and all but swept away most of the least drought-resistant species. The dry early spring and later summer of 1935 witnessed great increases in needlegrass, western wheat grass, and the invasion of a host of weeds. The favorable spring of 1936 promoted an abundant growth and emphasized the great changes in the prairie flora.


Bulletin No. 272 - Transmissibility Of Bang's Disease Among Dairy Cattle In A Utah Dairy Village, D. E. Madsen, O. G. Larsen Jul 1936

Bulletin No. 272 - Transmissibility Of Bang's Disease Among Dairy Cattle In A Utah Dairy Village, D. E. Madsen, O. G. Larsen

UAES Bulletins

For a number of years it has been generally recognized that one of the most satisfactory methods of controlling Bang's disease in dairy cattle is to locate spreaders by means of the agglutination test and to eliminate them from the herd. The success of such a plan in relation to Utah dairy herds was not clearly understood because of the physical farm set-up peculiar to many communities in this state. The village of Hyde Park where this study was made is organized on such a community basis. Usually, a house and livestock buildings are constructed on the town lot, consisting …
