Evaluation Of Urea And Dried Whey In Diets Of Cows During Early Lactation, David Paul Casper
Evaluation Of Urea And Dried Whey In Diets Of Cows During Early Lactation, David Paul Casper
Electronic Theses and Dissertations
Previous research indicated that soluble nitrogen may be utilized more efficiently for rumen microbial production in diets containing dried whey. To further evaluate this, 33 Holstein, cows (30 multiparous and 3 primiparous) were fed one of three concentrate mixes containing all natural proteins (SBM). 1% urea (U), or 1% urea and 30% dried whey (UDW) from wk 3 through 16 postpartum. Urea replaced portions of the soybean meal in the SBM mix while dried whey replaced portions of the corn and soybean meal. Cows were fed total mixed rations consisting of 40% (dry matter basis) corn silage, 10% alfalfa hay, …
The Effect Of Varying Lysine Levels In Starter Diets On Pig Performance And On Subsequent Performance And Carcass Characteristics, Robert C. Thaler
The Effect Of Varying Lysine Levels In Starter Diets On Pig Performance And On Subsequent Performance And Carcass Characteristics, Robert C. Thaler
Electronic Theses and Dissertations
Lysine is the first limiting amino acid in most cereal-based diets for swine. Thus, in cereal-based diets the lysine- requirement must be met first if the pig's protein anabolism is to be efficient and maximal. The most widely used diet in the swine industry today is the corn-soybean meal diet. Corn is deficient in lysine, but soybean meal is a relatively good source of lysine, so soybean. meal is added to the corn base to increase the diet's lysine content. Synthetic lysine also can be added to corn-soybean meal diets to increase lysine content or added as a replacement for …

The genus Echinacea, family Asteraceae, contains several species of herbaceous, warm season perennials possessing varying amounts of biologically active materials. Echinacea is indigenous to the central or west-central U.S. and ranges from Texas and Alabama to Saskatchewan in Canada. McGregor recognizes 9 species and 2 varieties of Echinacea; the taxa of western distribution occurring in dry areas of prairie and grassland ecotype, those of more eastern distribution in dry, rocky, open woodlands, hillsides, or glades. All taxa are considered to be drought-tolerant, disease and pest-resistant plants of agriculturally marginal land. Morphological variation within this genus has led to much debate …
S.I. Hayakawa And The Use Of Danger Indicators Of General Semantics, Janine Rae Rudnick
S.I. Hayakawa And The Use Of Danger Indicators Of General Semantics, Janine Rae Rudnick
Electronic Theses and Dissertations
Many books and articles have been written about general semantics and specific phrases included in general semantics study. The books generally have a theme of the meaning of words. Very few books or articles, however, have stressed the importance of J. Samuel Bois' danger indicators as part of the meaning of words. "Ego statements" 11 and "either or" 12 indicators have been touched upon in books and articles, but no one has dedicated significant study to the specific danger indicators as presented by Bois. It is this writer's belief that the danger indicators of general semantics should be studied more …

Effects Of Dietary Dehydroepiandrosterone (Dhea) On Body Weight, Food Consumption, And Glucose-6-Phosphate Dehydrogenase (G6phd) Activity In Lethal Yellow (Ay/Aw) And White-Bellied Agouti (Aw/Aw) Mice (Strain 129/Sv), Lisa Deette Staber
Electronic Theses and Dissertations
Dehydroepiandrosterone (DHEA) is a non-competitive inhibitor in vitro of glucose-6-phosphate dehydrogenase (G6PDH), the rate controlling enzyme in the pentose-phosphate shunt. This pathway produces NADPH, a necessary co-factor for the synthesis of fatty acids and ribo- and deoxyribonucleotides. Some researchers believe that by decreasing G6PDH activity, DHEA produces an anti-obesity and anticarcinogenic effect in laboratory mice and rats genetically inclined toward obesity and cancer. It is DHEA's anti-obesity effect which lends it to the study of the yellow obese (AY/-) mouse with its peculiar pleiotropic syndrome. Yellow obese AY/AW mice were found to be more susceptible to dietary DHEA's effects than …

The Economic Feasibility Of Small Scale Cooperatively Organized Fuel Alcohol Production In Eastern South Dakota, Daryl Arthur Brehm
The Economic Feasibility Of Small Scale Cooperatively Organized Fuel Alcohol Production In Eastern South Dakota, Daryl Arthur Brehm
Electronic Theses and Dissertations
Research on the economic feasibility of a cooperatively organized small-scale fuel alcohol plant is justified for several reasons. Policy makers could consult the results of this study as an aid in making decisions about public subsidies for fuel alcohol production. Investors concerned about the wisdom of allocating capital to this type of fuel alcohol production facility are also potential beneficiaries of this research. Perhaps most importantly, this information would be valuable to farmers in eastern South Dakota. Alcohol plants organized on a cooperative basis could reduce the individual financial risk of farmers involved--by spreading commitments among all the cooperative's members. …
Effects Of Anabolic Implants And Breed Group On Carcass Traits And Palatability Characteristics Of Bullock Beef, Roger C. Johnson
Effects Of Anabolic Implants And Breed Group On Carcass Traits And Palatability Characteristics Of Bullock Beef, Roger C. Johnson
Electronic Theses and Dissertations
The ultimate goal of the beef industry is efficient production of beef that satisfies the consumer and increases demand. In the past, American producers have been primarily interested in the production of high quality beef because consumers were concerned with meat palatability, particularly tenderness. However, due to current diet-health issues and economic conditions, American consumers have come to expect acceptable palatability and are now more concerned with the nutrient density and cost of their meat purchases. Maximum production efficiency must be realized to keep beef competitive with other protein sources for consumer dollars. Production systems must be used that are …

The Effect Of Varying Dietary Selenium Levels, Selenium Source And Dietary Composition On Growing Swine, Terry B. Goehring
The Effect Of Varying Dietary Selenium Levels, Selenium Source And Dietary Composition On Growing Swine, Terry B. Goehring
Electronic Theses and Dissertations
During the early 1900's, many stockmen in the western Great Plains suffered huge economic losses due to poisoning of their livestock through consumption of seleniferous plant material. Some were forced to discontinue raising livestock entirely and turned to grain farming. However, grain produced on land high in selenium was discounted on the market. Today, this grain marketing problem does not exist to the extent of that of the early 1900's. Selenium has more recently been recognized as an essential micronutrient for several species including swine. The Food and Drug Administration (FDA) has approved sodium selenite and sodium selenate as supplements …

An Examination Of Prostaglandins As Causative Agents In Pine Needle (Pinus Ponderosa) Abortion, Daniel P. Shue
An Examination Of Prostaglandins As Causative Agents In Pine Needle (Pinus Ponderosa) Abortion, Daniel P. Shue
Electronic Theses and Dissertations
Cow and calf losses due to pine needle abortion in cattle grazing foothill ranges of ponderosa pine (Pinus ponderosa) continue to cause managerial and economic problems for ranchers in South Dakota, Colorado, Idaho, California, Montana and many areas throughout Canada. Because of its overall economic significance, investigators have been attempting to isolate and characterize causative agents of pine needle abortion. To date, a large number of pine needle constituents have been shown to possess abortifacient capabilities. In addition to actual pine needles, it appears that several other undefined factors may be associated with, and (or) predispose animals to, pine needle …
