The Feeding Value Of High Dry Matter Corn Silage, Myers J. Owens
The Feeding Value Of High Dry Matter Corn Silage, Myers J. Owens
Electronic Theses and Dissertations
The important of corn in dairy cattle feeding is generally acknowledged. A popular way of preserving the crop is to make corn silage, thus using the whole plant for feed and preserving maximum feed per acre. The increased utilization of corn silage by dairymen may be due to its high energy yields per acre, high acceptability by cattle, and ease with it is incorporated into automated systems of harvesting and feeding. The increasing importance of corn silage in the United State is evidenced by the increasing acreages harvested as corn silage. In 1950 there were 4,937,000 acres planted with a …

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

Digestibility Studies With Western Wheat Grass, Marvin John Wurster
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 …

Factors Affecting Body, Texture, And Water Holding Capacity Of A New Low-Fat Spread-Type Dairy Product, Basil K. Dalaly
Electronic Theses and Dissertations
At the South Dakota State University Dairy Science Department, a challenging work is being conducted to develop a new spread type· dairy product which is made almost entirely of dairy ingredients. It contains about 40% fat, 6% protein, 40% water, and 1.9% salts. Among the problems which faced the workers on this project were the process induced changes in the protein and the water holding capacity, which are interlinked. The problem of water holding capacity is increased by the high water content of the product compared with butter, which contains about 16% water. Maintaining the stability of the fat emulsion …

A Modified Voges-Proskauer Method Of Determining Diacetyl In Dairy Cultures, Dwain Finkenbiner
A Modified Voges-Proskauer Method Of Determining Diacetyl In Dairy Cultures, Dwain Finkenbiner
Electronic Theses and Dissertations
Dairy scientists have known for a number of years that diacetyl is one of the principle flavor components of butter, buttermilk, and cheese cultures. Of the tests which have been introduced to determine diacetyl, one of the first was the heavy metal gravimetric method. This procedure involved distillation of the diacetyl from the mother substance. The most common derivative formed was nickel dimethylglyoximate. Principle disadvantage of this method were that large amounts of sample were required for steam distillation when the products were low in diacetyl. It was also a time consuming procedure because the steam distillation could take as …

Characterization Of Staphylococcus Species Isolated From Raw Milk With Special Reference To The Enterotoxigenic Coagulase-Positive Types, Adnan M. Ammouri
Electronic Theses and Dissertations
Numerous reports from many parts of the world have described the occurrence of outbreaks of staphylococcus food poisoning. Some studies have incriminated raw milk as a reservoir of the staphylococcus organisms as the vehicle of transmission. Recently Cheddar cheese has been implicated as the contaminating agent in food poisoning outbreaks traced to dairy products. The frequency of outbreaks of staphylococcus food poisoning has stimulated interest in the characterization of members of the staphylococcus genus. The strains particularly important are those capable of production an enterotoxin. In order to determine the strains of staphylococcus organisms isolated from raw milk which are …
The Effect Of Frozen Storage On The Microflora Of Raw Milk, Jaswant Singh
The Effect Of Frozen Storage On The Microflora Of Raw Milk, Jaswant Singh
Electronic Theses and Dissertations
The proper handling of milk samples prior to bacterial analysis has been somewhat of a problem to dairy processors of South Dakota. There have been, and still are, many queries by these people about the treatment of o milk sample prior to the determination of a bacterial count. Should the milk samples be frozen prior to determining the number of bacteria? If it is feasible, what effect will the freezing have on the number of bacteria found? No tangible information about this problem has been found in the literature. Standard procedure emphasize mainly the icing of milk sample before analyzing …
Comparative Study Of Milk Quality Tests On Manufacturing Grade Raw Milk, Donald L. Wallace
Comparative Study Of Milk Quality Tests On Manufacturing Grade Raw Milk, Donald L. Wallace
Electronic Theses and Dissertations
One criterion used to determine the quality of milk is based upon its bacterial content. This immediately emphasizes the problems of determining milk quality. Bacteriological tests are, at best, only estimates of the number or the activity of the organisms present. Since its introduction to South Dakota dairy farms, the bulk tank has continued to increase in popularity. Its increased acceptance has caused new problems in determining milk quality. The bulk tank allows the farmer to cool the milk faster and more efficiently than ever before, thereby limiting bacterial growth. Quality tests should not only differentiate between good and poor …

Effectiveness Of An Aspergillus Oryzae Culture On The Preservation Efficiency And Feeding Value Of Alfalfa-Brome Haylage Stored In Gas-Tight And Concrete Stave Silos, Samuel C. Perry
Electronic Theses and Dissertations
High-quality forage is essential in feeding dairy cattle if dairymen intend to increase milk production or to maintain a high level of production. Problems of preserving high-quality forage for the winter feeding of livestock occur each year. The preservation of legumes and grasses as hay is governed by a number of factors: (1) curing weather, (2) state of maturity of the crops, and (3) other factors such as equipment available and methods of handling the crop. The inability of dairymen to control these factors results in heavy nutrient loses in the hays during the curing process due primarily to leaching …

The Production And Ingestion Of Antibodies In Milk, George Donald Marx
The Production And Ingestion Of Antibodies In Milk, George Donald Marx
Electronic Theses and Dissertations
Since biblical times man has depended upon the cow for nourishment. The cow’s contribution to human and animal welfare has been tremendous. These contributions may be increased by artificially producing antibodies in milk. In view of recent experiments the established theory that antibodies cannot pass the intestinal wall after the animal is a few days of age may not be true. Much information has been gathered to support this theory. Since the mammary gland is capable of producing a considerable quantity of antibodies and since antibodies inhibit disease, the milk should be an excellent source of antibodies for disease protection …
A System For Making Selective Matings In Dairy Cattle, Basil Ralph Eastwood
A System For Making Selective Matings In Dairy Cattle, Basil Ralph Eastwood
Electronic Theses and Dissertations
The term “selective matings” implies the selection of a sire to breed to each female on an individual, rather than a group or herd basis. Mating systems, other than random mating, may be classed either as the mating of like to like or as the mating of unlikes. This likeness or unlikeness may be based either on blood relationship or on individual appearance. The advantage and limitations of each mating system have been well worked out on a theoretical basis, and some of system have been thoroughly tested by experimentation and in the field. In actual practice many breeders use …
Effects Of Reserpine (Serpasil) On Bloat, Edward P. Michalewicz
Effects Of Reserpine (Serpasil) On Bloat, Edward P. Michalewicz
Electronic Theses and Dissertations
Farmers and ranchers have been faced with the problem of bloat for many centuries. Thus far there has been little concrete evidence form research in determining the cause, finding a cure or a preventive for bloat. Numerous preventives for bloat have been practically useless. Investigators have used oils and paraffin’s as prophylactic and therapeutic measure against legume bloat. Antibiotics have been used as preventatives with some success, antifoaming agents have little effect and are of short duration. Tranquilizers, a comparatively a new group of compounds, have produced spectacular results in combatting stress conditions in animals. The ideal effect of tranquilizers …
Summary Of Research On Diethlstilbestrol For Growing And Fattening Beef Cattle, D.V. Radabaugh, L.B. Embry
Summary Of Research On Diethlstilbestrol For Growing And Fattening Beef Cattle, D.V. Radabaugh, L.B. Embry
Agricultural Experiment Station Animal Husbandry Pamphlets
Numerous experiments on the response of growing and fattening cattle to stilbestrol have been reported in recent years. There has been a response to stilbestrol in most of these experiments, though to varying degrees. Many of the reports have been of a preliminary nature and in several instances have covered only one trial. A review of such experiments individually does not present a clear and concise picture of the effects of stilbestrol treatment. Therefore, results of most of the reported experiments have been reviewed and are summarized in the tables in this pamphlet. Four rather distinct phases of cattle feeding …
