Effects Of Supplemental Lysine In The Drinking Water Of Growing And Finishing Swine, Aaron R. Taylor
Effects Of Supplemental Lysine In The Drinking Water Of Growing And Finishing Swine, Aaron R. Taylor
Electronic Theses and Dissertations
Proteins are defined as organic compounds formed as polymers of amino acids. The structural characteristics of the individual proteins enable them to act as catalysts (enzymes) and thus control the rate of all biological reactions, to serve as carriers for biologically important substances in the organism, to regulate physiological relationships as hormones, and to serve as structural components for subcellular, cellular and other organic substances. Previous research has indicated that for optimum utilization of amino acids to occur the required amino acids must be present at the site where synthesis of the organic substances takes place. These required amino acids …
Variation Between Boars In Semen Characteristics And Fertility, Wayne L. Singleton
Variation Between Boars In Semen Characteristics And Fertility, Wayne L. Singleton
Electronic Theses and Dissertations
The most important factor influencing the income from a livestock breeding herd is the number of offspring produced per female per year. This number varies between herds and species and is influenced by such factors as disease, nutrition, genetics, management, climate, and endocrine balance. It has been estimated that over 30% of the potential offspring from the sow are lost between ovulation and the thirtieth day of pregnancy. It would be of great economic value to reduce this loss both in terms of increased number of offspring per pregnancy and increased number of offspring per year. The sow has long …
Relationships Between Beef Palatability And Bone Density, Bone Hardness And Other Maturity Indicators, David E. Schafer
Relationships Between Beef Palatability And Bone Density, Bone Hardness And Other Maturity Indicators, David E. Schafer
Electronic Theses and Dissertations
A trend in recent years has been for meat scientists to concentrate much of their effort on obtaining a more complete understanding of those factors which affect or contribute to meat quality or palatability. Some of these topics have ranged from the effect of nutritional regime on palatability to the effects of hormone treatments, antemortem stress conditions, breeds or types, sex, marbling levels, maturity or age, cooking techniques, chemistry of muscle and fat, measurement of muscle fiber diameter and extensibility, connective tissues and, finally, color of muscle and fat. This emphasis on factors relating to beef palatability has also caused …

Food Habits And Energy Utilization Of Badgers, Grant K. Jense
Electronic Theses and Dissertations
A study was initiated in 1966 to determine food habits and energy utilization of badgers. Digestive tracts were collected in eastern South Dakota from November 1966 to November 1967. A male and a female badger were used for two energy-balance and three digestion trials. Ground squirrels, mice and rabbits were found to be the most important mammal foods eaten. Birds and eggs were only eaten during spring and summer. Toads and grains were important fall foods. Insects were eaten throughout the year but usually only in trace amounts. However, when available, badgers ate large quantities of beetles and ground-nesting bees. …

Yield Components Of Spring Oats As Affected By Seeding Rate And Fertility Level, Robert Yung-Yen Yeh
Yield Components Of Spring Oats As Affected By Seeding Rate And Fertility Level, Robert Yung-Yen Yeh
Electronic Theses and Dissertations
Experiments with oats have shown approximately equal yields from a wide range of seeding rates. Also, oats usually respond to an adequate supply of plant food elements. Yield is a product. As Grafius (12) pointed out, the yield of oats may be represented geometrically as the volume of a rectangular parallelepiped with edges X1= number of panicles per unit area, X2= average number of seeds per panicle, and X3= average weight per seed. Multiplied together X1X2X3 equals Y, yield. All changes in the yield components need not be expressed as changes in yield, but all changes in yield must be …
Supplemental Vitamins In The Drinking Water For Early Weaned Pigs And Growing Rats, Marvin Eugene Wastell
Supplemental Vitamins In The Drinking Water For Early Weaned Pigs And Growing Rats, Marvin Eugene Wastell
Electronic Theses and Dissertations
Vitamins are defined as organic compounds required in small amounts to perform many essential functions in the animal body. All vitamins have different structures and perform different functions. Experimental research has shown that it is very important to supply adequate amounts of vitamins to insure normal growth and body maintenance of animals. Swine producers use completely mixed diets or the free choice feeding of corn and supplement, which includes proteins, minerals, vitamins and additives, as methods of supplying supplemental vitamins for pigs. These two methods have been accepted by modern swine producers as good feeding programs because they have supported …

Feedlot Performance Of Hereford And Holstein Steers As Affected By Ration And Slaughter Weight, William M. Larson
Electronic Theses and Dissertations
In 1918 the Bureau of Markets, now the Bureau of Agriculture Economics, of the United States Department of Agriculture inaugurated its market reporting service on livestock in Chicago. At that time a uniform standard was set up for market classes and grades of cattle. The use of these uniform descriptions for all classes and grades of cattle throughout the country by researchers, producers, selling and buying agencies and packers has contributed a great deal to the orderly marketing of cattle and to the reporting and exchange of research information. The grade of a particular animal is determined by the apparent …
Nitrate--Urea Interrelationships In Sheep, Donald Wayne Hoar
Nitrate--Urea Interrelationships In Sheep, Donald Wayne Hoar
Electronic Theses and Dissertations
Nitrates are absorbed from the soil by plants and serve as a source of nitrogen which is converted into protein and other nitrogen containing compounds. Plants usually contain relatively small amounts of nitrate because it is converted into other nitrogenous compounds rapidly after being absorbed. Under certain conditions some plants may accumulate fairly high concentrations of nitrate. While these high concentrations are not toxic to the plant, animals consuming them may sometimes show symptoms of nitrate toxicity. Nitrate is not very toxic, but it is readily converted into nitrite which causes toxicity. Nitrate is not very toxic, but it is …
Supplemental Vitamins In Feed And Water For Growing And Finishing Pigs And Growing Rats, Vernon L. Fritz
Supplemental Vitamins In Feed And Water For Growing And Finishing Pigs And Growing Rats, Vernon L. Fritz
Electronic Theses and Dissertations
Vitamins in swine diets have become more important in recent years as swine producers have changed to the confinement method of rearing pigs. When confined, swine are more likely to suffer from nutritional deficiencies, especially a deficiency of vitamins. However, with greater knowledge of nutrition and establishment of vitamin requirements, swine producers are now able to include the essential nutrients (carbohydrates, fats, proteins, minerals and vitamins) and feed additives in a completely mixed diet. This method of feeding swine has been widely accepted since completely mixed diets support excellent gains and feed utilization; however this method of feeding is not …

The Relationship Of Live And Carcass Measurements To Carcass Meatiness And The Influence Of Sex And Sire On Carcass Traits In Lambs, Robert E. Fritz
Electronic Theses and Dissertations
The changing demands of the consumer have caused quite an influence on our breeding, feeding and management programs. The consumer is better educated and spends more time selecting which cut or cuts of meat to buy. The desire of the consumer to purchase leaner cuts and cuts with more eye appeal has influenced producers to select parent stock with more desirable meat qualities, and animal scientists to strive to find measures which producers could use in their selection programs in order to produce more red meat and less fat. The popularity of other meats has increased and the per capita …
The Effect Of Range Site And Range Condition On The Growth And Development Of Western Wheatgrass, Myron Eugene Enevoldsen
The Effect Of Range Site And Range Condition On The Growth And Development Of Western Wheatgrass, Myron Eugene Enevoldsen
Electronic Theses and Dissertations
One of the problems confronting the range administrator or ranch manager in making sound grazing management decisions is lack of detailed knowledge about the growth and development of herbage grasses. It is important to know how the desirable grass species in a particular area will respond to the time and frequency of harvesting in order to formulate a grazing management plan that will permit maximum sustained livestock production while maintaining or improving the species composition and the vigor of the important forage plants. Taller and more palatable grasses are replaced by shorter grasses as grazing intensity is increased; thus, foliage …

Effects Of Supplemental Lysine And Methionine In Finishing Swine Diets, Bruce A. Eason
Electronic Theses and Dissertations
Considerable research has been conducted in the last few years to evaluate protein and amino acid levels in the various growth phases of porcine animals. Most of this research has been limited to the baby and growing phase of the pig, whereas little research has been conducted with the finishing phase of the pig. Lysine and methionine, essential amino acids in the diet of monogastric animals, have been studied extensively in animal nutrition. The following experiments were designed to gain some insight into the effects of supplementing two crystalline amino acids, lysine and methionine, to a corn-soybean meal-tankage diet for …

Effect Of Thiamine, Riboflavin, Pantothenic Acid, And Niacin In Bovine Blood On The Economy Of The Short-Nosed Cattle Louse Haematopinus Eurysternus (Nitzsch), John Roger Crouch
Electronic Theses and Dissertations
A livestock producer will usually experience a louse infestation among his cattle sometime during his career. Most of the cattle that become louse-infested are easily ridded of their lice. There may be, however, one animal in a herd which is particularly susceptible to the lice and becomes chronically infested. Sometimes the susceptible animal may become so heavily infested with lice that death occurs. Scharff (1962) stated that the death loss resulting from very heavy infestations of the short-nosed cattle louse, Hematopinus eurysternus (Nitzsch) was probably about one percent. The louse involve in the experiment was the short-nosed cattle louse, Hematopinus …

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. Isolated soy protein which is commonly used for purified diet studies contains factor(s) which cause reduced growth and a rachitic-like conditions of turkey …
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 …

A Study Of Seventh And Eighth Grade Home Economics Programs In South Dakota With Implications For Curriculum Development, Lacquita Olson Wagner
Electronic Theses and Dissertations
One of the basic requirements of curriculum building is a clear and concise understanding of social, economic and technological developments which influence the American way of life. In fact curriculum revision is needed because of these rapid changes which are often so rapid that the educator has difficultly interpreting their implications. A first step in curriculum reorganization according to Trump and Baynham involves an analysis of what is being tought and studied by students.9 It was with this thought in mind that the writer developed a questionnaire which was sent to teachers in the public schools teaching homemaking in the …
