A Bacteriological Study Of Abscesses Of Swine And Cattle, Lawrence Joseph Biever

Electronic Theses and Dissertations

Condemnation of abscessed portions of swine and beef carcasses is an important economic problem to the meat packing industry and, consequently, to the individual stock producer. The Meat Inspection Division of the Agricultural Research Service of the U.S. Department of Agriculture, in its summary of activities from 1955 through 1969 (2), reported that the numbers of abscessed portions from cattle and swine have increased (Table 1 and Figure 1). In this 10-year period the number of abscessed parts condemned in swine increased from 1.4% (1,397,248) of the animals slaughtered to 3.9% (2,660,522). During the same period of time the number …

An Economic Analysis Of Livestock Auctions In South Dakota, Donald K. Bendt

Electronic Theses and Dissertations

The structure of the livestock industry in the United States has undergone change in the past three decades. Integration, scale economies, changed eating habits, production and processing innovations, decentralization and increased demand for service have all affected the market structure. During this change, however, livestock auctions have remained important outlets for marketing livestock. Since the establishment of the first auction at Yankton in 1930, livestock auctions in South Dakota have become increasingly important.1 By 1937 the number had increased to 34. In 1964 there were 58 auctions operating in the state handling an annual volume of almost three million head …

Hydrogen Sulfide Formation By Escherichia Freundii From Organic Compounds, Martin Bembers

Electronic Theses and Dissertations

The evolution of hydrogen sulfide by microorganisms has been studied for many years. Until recently, most of the research was in the taxonomical and clinical areas. Much work was done to perfect a cultural medium capable of demonstrating hydrogen sulfide production, using this characteristic to distinguish between groups of organisms. Triple sugar iron agar, Kliglers, lead acetate agar, urea agar base concentrate, and peptone iron medium used today. The extensive investigation was to find medium to show a color change in response to hydrogen sulfide production without toxicity to the growing cells. Hydrogen sulfide producing bacterial have been isolated from …

The Response Of Poults To Growth And Antirachitic Factors Of Soybean Meal And Corn, Richard Lane Arnold

Electronic Theses and Dissertations

Soybean by-products have been used for animal feed protein extensively in the past years. Soybean meal has become a major source for poultry diets. Being a plant source of protein soybeans potentially could provide protein for animals in almost unlimited quantities. However, there are certain problems encountered in the feeding of soybean products to poultry. The research for this paper deals with the use of soybean the use of soybean protein in the diets of turkey poults.

Nitrogen Utilization From Soybean Meal And Urea By Normal And Protozoa-Free Lambs, R. M. Luther, J. L. Perkins

South Dakota Sheep Field Day Research Reports, 1967

Proteinaceous feed and other nitrogenous materials ingested by ruminant animals undergo extensive degradation by bacteria and protozoa in the forestomach (ruminotericulum). Ammonia, the chief and end-product of the digestion of food protein in the rumen, is used by rumen microorganisms in synthesis of microbial protein.
The rate and quantity of ammonia produced in the rumen has an important influence on the efficiency of protein utilization by ruminants. Soybean meal appears to be degraded rather slowly in the rumen. On the other hand, urea is rapidly hydralyzed with a rapid release of ammonia. Such differences may have an important influence on …

Research Reports Concerning Different Aspects Of Pre-Flushing And Flushing Treatments, F. W. Whetzal

South Dakota Sheep Field Day Research Reports, 1967

Several factors are known to determine the prolificacy of the ewe. One of the factors is nutritrion and particularly nutrition prior to mating. The practice of improving nutrition of the ewe prior to mating to increase lambing percentage is widely advocated and adapted in sheep producing countries. It has been shown that flushing of ewes is generally quite beneficial in increasing the number of lambs born. It is reported however, that when ewes are in high condition or have a low gentic potentially for twinning, little or no response will result from flushing. Following are summaries of experimental trials showing …

Corn Rootworm Control In South Dakota With Notes On Wireworm And Cutworm Control, Cooperative Extension South Dakota State University

SDSU Extension Fact Sheets

Resistant strains of the western corn rootworm are causing a serious insect problem in South Dakota. The western, northern, and southern species have been present for a number of years. However, the first evidence of resistant strains of western corn rootworm in South Dakota was observed in 1962. Treatment failures using aldrin and heptachlor, later checked by laboratory tests on adult beetles, indicated that the western corn rootworm population in Lincoln County in southeastern South Dakota was becoming resistant.

Preparation And Marketing Of Wool, J. A. Minyard, Kenneth Leslie

South Dakota Sheep Field Day Research Reports, 1967

Wool provides an important source of income from the sheep flock. The contribution of wool to total flock income can vary widely depending on breed of sheep, climate, feed, management, price of wool and other factors. Under favorable conditions of production and prices, sale of wool may account for up to 40 per cent of the total reuturns from "wool sheep".

Fox-Prey Relationships In Eastern South Dakota, Robert L. Drieslein

Electronic Theses and Dissertations

Relationships between red foxes (Vulpes fulva) end their principal prey, particularly ring-necked pheasants (Phasianus colchicus), were studied on four units in eastern South Dakota from December 1964 to September 1966. Each unit was composed of a 100-square-mile "reduction area," on which fox populations were reduced, and a 100-square-mile "check area," on which fox populations were not reduced for the study. Indices to populations of foxes, pheasants, mice, eastern cottontails (Svlvilagus floridanus) and whitetail jackrabbits (Lepus townsendi) were obtained and used to evaluate food habits and the effect of predator reduction on prey populations. Four-hundred seventeen stomachs and 104 female reproductive …

Seasonal Movements Of Prairie Grouse In South Dakota, Warren W. Jackson

Electronic Theses and Dissertations

From 1962 through 1966, 1,401 plains sharp-tailed grouse (Pedicecetes phasianellus jamesi) and greater prairie chickens (Tympanuchus cupide pinnatus) were trapped in Gregory and Lyman Counties in south-central South Dakota. Cannon-projected nets and funnel traps were used to capture prairie grouse on breeding grounds and winter baitsites. Some birds were marked with backtags and leg-markers. Movement information was obtained from field observations, hunter reports, sharp-tailed grouse collections, and by recapturing banded birds. Male birds moved less than two miles from winter baitsites to breeding areas; most movements over five miles were made by immature female birds. Seventy-seven percent of the hunter …

Comparison Of Two Cultures For Use In Preacidified Skimmilk For Cottage Cheese Manufacture, Daryl D. Boddicker

Electronic Theses and Dissertations

Curd formation in a cultured dairy product is brought about by the addition of a bacterial culture capable of producing lactic acid from lactose. The primary function of this culture is to produce sufficient lactic acid to cause coagulation of the caseinate system of skimmilk. A secondary function of the culture is the production of flavor compounds considered to be desirable in these products. The flavor compounds produced by the normal growth of citric acid fermenting organisms are water soluble, and are largely removed during washing of the Cottage cheese curd. Therefore, flavor compounds are normally added to the cheese …

The Influence Of Artificial Insemination In Three Midwestern States, Wendell Lee. Kucker

Electronic Theses and Dissertations

Increased productivity of dairy cattle depends in part upon genetic changes brought about by select ion. Because of the long generation interval and low reproductive rate, genetic improvement in dairy cattle is slow. For this reason, the accuracy and effectiveness of selection of sires is of utmost importance. Selection of sires plays a major role in the genetic improvement of dairy cattle since a sire can leave many more descendants than a female. Consequently, the use of outstanding males is important in the genetic advancement of the dairy cattle population in the upper mid west as well as throughout the …

Consumer Evaluation Of A New Low-Fat Spread-Type Dairy Product, Walter W. Wosje

Electronic Theses and Dissertations

For many years the dairy industry has been going through transitional period whereby many marketing and structural changes have resulted. Generally speaking, these changes have been advantageous to the dairy farmer. During the past years there has been a widespread and increasing interest in profitable means of utilization of dairy by-products. Because of their unique and high nutritional value, the most logical method of disposition of these by-products is, from the standpoint of the general welfare, in human food; generally this is also the most gainful method. The high nutritional value of these products also makes them valuable in feeding …

On The Nature Of Some Selenium Losses From Soils And Waters, Ghaleb Musa Abu-Erreish

Electronic Theses and Dissertations

Selenium is of interest to the animal nutritionists and to the biochemist from two standpoints. In some areas of the world it occurs in soils in excesses, and the plants growing in these soils contain levels of the element that are toxic to livestock that consume the plants. On the other hand, selenium appears to be essential to the well-being of certain animals, at least under some feeding regimens, and in a number of areas the soils produce feeds that are deficient in the element (48). In either case, an understanding of the cycling of selenium in nature is essential …

Digestibility Studies With Western Wheat Grass, Marvin John Wurster

Electronic Theses and Dissertations

In order to make the most economical usage of our range forages it is essential that we know when the forage is most digestible in order for livestock to obtain maximum benefit from it. For many years cutting date has been the most common measure used to determine when a forage contains the most nutritive value. In many grasses emergence of the seed head or seed maturity has been used to determine when a particular forage should be harvested, However, western wheatgrass (Agropyron mithill) is not dependent on seed for reproduction and under range conditions often does not produce a …
