Effects Of Various Dietary Salt Additions On Silica Urolithiasis In Male Rats, Carl J. Schreier
Effects Of Various Dietary Salt Additions On Silica Urolithiasis In Male Rats, Carl J. Schreier
Electronic Theses and Dissertations
Urinary calculi composed primarily of silica have been identified in range animals by several researchers. Silica calculi have also been found in dogs, humans, rats and guinea pigs. Forman et al conducted a detailed analysis of calculi. They found.that ashing at temperatures of 1500 C decreased calculi weight by 20%. Silica and calcium were shown to make up most of the remaining mineral content. Calculi from grazing ruminants in western Australia contained Si02, but further analysis showed that they were a mixture of substances. Mcintosh found that of the calculi analyzed 47% contained weddelite (Calcium oxalate.H20) and opaline silica, 13% …
Ozonation And Manganese Greensand Filtration For Iron And Manganese Removal From A Municipal Groundwater Supply, Cary Pieterick
Ozonation And Manganese Greensand Filtration For Iron And Manganese Removal From A Municipal Groundwater Supply, Cary Pieterick
Electronic Theses and Dissertations
Stoebner and Schjodt both used a pilot plant which treated raw water with ozone gas for the oxidation of iron am manganese and then passed the treated water through an anthracite coal filter. Both agree that the degree of iron and manganese oxidation was greatly affected by changes in ozone dosage but was not greatly affected by changes in detention time. Both also experienced limited filter runs between backwashing because of iron and manganese breakthrough in the filter effluent. Kirscherman used a pilot plant that involved aeration, potassium permanganate (KMnO4) treatment, basin detention, and filtration through a dual media (manganese …
The Effect Of Photoperiod, Ergocryptine Injection And Melatonin Feeding On Reproduction In The Ewe, Cindie Marie Luhman
The Effect Of Photoperiod, Ergocryptine Injection And Melatonin Feeding On Reproduction In The Ewe, Cindie Marie Luhman
Electronic Theses and Dissertations
One of the most intriguing aspects of reproduction is the reversible fertility governing seasonal breeding. Sheep are one of the many species that exhibit a circannual rhythm in reproduction, because they start estrous cycles in fall and winter months and become anestrus in spring and summer months. Seasonal changes appear to control this. Ewes seem to be more completely seasonal than are rams because only very limited ovarian activity, fewer follicles, and no ovulation occurs in ewes, although follicular size remains unchanged. Most rams will produce viable semen throughout all seasons, however, Lincoln and Short and Almeida and Lincoln reported …

A Comparison Of Type Of Birth, Breed Of Sire, Postweaning Nutrition, And Age Of First Breeding On Lifetime Lamb And Wool Production In Range Ewes, Steven M. Kappes
Electronic Theses and Dissertations
Due to present economic pressures, sheep producers must utilize every management tool in the most profitable manner. Therefore, many traditional practices must be reevaluated. Research has indicated that some possible areas to improve lamb and wool production are in the use of crossbred ewes, breeding ewes to lamb at 1 yr. of age, feeding a high level of postweaning nutrition, and selection for twins, lamb production, wool production, longevity, and lifetime production. Research is usually performed at experiment stations where the conditions are not typical of those found for commercial operations and therefore may affect the application of the results. …

The Relationship Between Obesity And Fertility In The Lethal Yellow Mouse (Ay/A; C57bl/6j), Kim William Jeppesen
Electronic Theses and Dissertations
The lethal yellow gene, (Ay) is a genetic mutation in mice which causes a number of defects. First described in 1905 by Cuenot, the Ay/- mouse has been the subject of one hundred or more studies. Yet, primary genetic and molecular lesions caused by Ay remain unknown. Cuenot reported that Ay caused three aberrant phenotypic alterations; these included yellow coat color, obesity, and embryonic lethality in Ay homozygous embryos (Ay/Ay). Since 1905, a number of other Ay-induced abnormalities have been reported. Among these aberrations is Ay-induced reproductive senescence. It is this particular Ay character (i.e. reproductive failure of Ay/- mice) …

Plasma Pepsinogen Test For Hypobiotic Nematode Larvae In Abomasal Glands Of Sheep, Richard Alex Jensen
Electronic Theses and Dissertations
The American Association of Veterinary Parasitologists reported that nematodes in sheep represent an unquestionably great production loss, and that the absence of deworming on a routine basis would hamper modern sheep production. After ingestion, the infective third stage larva, or L3, exsheaths and burrows into the digestive glands, and becomes a fourth stage larva, or L4. According to Armour, 18 to 21 days after L3 ingestion occurs, the nematode reaches sexual maturity. However, while in the gastric glands, these L4 invade the parietal, or hydrochloric acid (HCl) secreting cells, damaging them, and replacing them with non-acid secreting cells. This leads …

The Effect Of Various Proteins And Amino Acids On Salenium Toxicity To Rats Fed Corn-Based Or Wheat-Based Diets, Ailene Annette Herr
The Effect Of Various Proteins And Amino Acids On Salenium Toxicity To Rats Fed Corn-Based Or Wheat-Based Diets, Ailene Annette Herr
Electronic Theses and Dissertations
Selenium occurs in the earth's crust in varying concentrations. It is crystallochemically related to sulfur, and sulfide ores frequently contain selenium. The commercial production of selenium is usually as a by-product of other mining operations, especially copper mining. It occurs in different oxidation states depending on the pH of the soils. At acidic pHs the predominate form is selenite. That present as selenite is bound to a high degree by iron colloids in soils and is thus not readily absorbed by plants. Once taken up by plants selenium becomes, to varying degrees, available to animals. Selenium can be either harmful …

Economic Feasibility Of Producing Fuel Alcohol From Fodder Beets In A Small-Scale Plant, Mohamed K. Habash
Electronic Theses and Dissertations
Oil is the principal energy form in all the major developed countries. Most nations domestically produce only trivial quantities. For most of these countries, the energy requirements are met predominantly by oil imports. The Arab oil embargo of October 1973 caused a dramatic jump in the real price of oil. Oil markets were further shocked in 1979 by the Iranian political crisis. Since the beginning of this instability in the world petroleum market, an extremely high level of public concern for liquid fuel energy sources has been created. Farmers have been hit hard by the increases in fuel costs; these …

Effects Of Breed Of Ewe And Management System On The Lifetime Production Of Lamb And Wool, Wayne Joseph Busch
Electronic Theses and Dissertations
Sheep production in the United States is highly variable. The sources of this variation are many and may include breed, climatic condition, management system and selection emphasis. The sheep is a highly adaptable animal and the success of an operation may be due in part to the ability of producers to select breeds of sheep best suited to their situation. Over time, two distinct management systems have developed. The first of these may be termed the farm flock system. The farm flock system is typical of the eastern United States in the crop farming areas of the country. This system …
Tryptophan And Threonine Requirements Of Pigs Fed A Low-Protein, Corn-Sunflower Meal Diet, Barton S. Borg
Tryptophan And Threonine Requirements Of Pigs Fed A Low-Protein, Corn-Sunflower Meal Diet, Barton S. Borg
Electronic Theses and Dissertations
The ultimate goal of the pork industry is efficient production of quality pork for the least monetary investment. Most swine diets are formulated using feedstuffs which supply 100% natural protein. Different protein sources differ in their amino acid content and availability. For example, soybean meal has been shown to contain more lysine than sunflower meal and the lysine in soybean meal is more available to the pig than that of sunflower meal. Protein sources which supply the correct balance of available amino acids relative to the needs of the animal are considered as being protein sources of the highest monetary …

The Effect Of Nutrition Education On The Dietary Intake Of College Students, Elizabeth Ann Pond
The Effect Of Nutrition Education On The Dietary Intake Of College Students, Elizabeth Ann Pond
Electronic Theses and Dissertations
According to Guthrie, nutrition professionals are especially concerned about the food habits of adolescents. Dietary inadequacies are higher during adolescence than at any other stage of the life cycle. Deficiencies in this age range can have fat reaching effects, especially for females. Female adolescent nutritive needs are surpassed only by those during pregnancy and lactation. The adolescent who becomes pregnant before growth is complete is of particular concern. If nutritive intake is inadequate before conception the adolescent and her unborn child are at high risk. Another nutritionally related concern in adolescence is the increased incidence of eating disorders such as …

Lungworm Infections, Reproduction And Summer Habitat Use Of Bighorn Sheep In Custer State Park, South Dakota, Gary C. Brundige
Electronic Theses and Dissertations
Bighorn sheep (Ovis canadensis) were once indigenous to the Black Hills and Badlands of South Dakota. When European settlers moved into this region during the late 1800' s, market hunting, loss of habitat, and introduction of animal diseases and parasites caused the subspecies of the region, the Audubon's bighorn sheep (O. c. auduboni), to become extinct by 1916 (Buechner 1960). To reestablish bighorn sheep in the Black Hills, 8 Rocky Mountain bighorn sheep (O. c. canadensis) were introduced into the former range of the Audubon's sheep in 1922. Finding the habitat to be very suitable, this small population increased to …

Identification Of Volatile Compounds Produced By Brevibacterium Linens That Inhibit Molds, Samuel E. Beattie
Electronic Theses and Dissertations
Mold contamination of processed food and its raw ingredients is a major concern in agriculture. Although at one time mold contamination of cheese and other foods was considered to be of little conse9uence, discovery of carcinogenic and/or teratogenic toxins (73) produced by molds commonly associated with food has changed this innocuous and frequent inconvenience into a serious health consideration. The presence of mold on or in cheese is a common occurrence, indeed, many cheeses depend upon molds to provide characteristic cheese flavor and texture. Cheeses such as blue, Roquefort, Camembert, and Brie are ripened under controlled conditions by species of …
