Ovine Body Composition As Influenced By Live Weight, Wallace Jon Koester Jan 1971

Ovine Body Composition As Influenced By Live Weight, Wallace Jon Koester

Electronic Theses and Dissertations

Breeders are looking today for larger, growthier animals which will produce a fast gaining market lamb. The market animals must be able to reach a desirable weight with a correct amount of finish. The weight at which these lambs are marketed influences average daily gain and feed efficiency. This market weight often depends upon the availability and cost of feed. When market prices look favorable for the future, the producer tends to put additional weight on his lambs in order to obtain a greater total return. The producer is usually encouraged to market his products at weights which maximize feed …

Embryogeny In Haemmanthus Albiflos Jacquin, Ping-Fai David Lo Jan 1971

Embryogeny In Haemmanthus Albiflos Jacquin, Ping-Fai David Lo

Electronic Theses and Dissertations

There has been concern over the controversial position of the genus Allium in the classification scheme. Allium has been put into the Liliaceae because of its superior ovary and into the Amaryllidaceae because of umbels subtended by membranaceous bracts. The first purpose of this investigation is to study the embryogenesis and subsequent embryogeny of Haemanthus to evaluate affinities between Allium and Haemanthus. Since Allium has stalked cotyledons, it was thought that we could appeal to Haemanthus embryogenesis for evidence as to its relationships, since it is a genus which has been considered both primitive with the Amaryllidaceae and related to …

Food Habits Of Deer In The Southern Black Hills As Determined By The Point Technique, Theron E. Schenck

Electronic Theses and Dissertations

White-tailed (Odocoileus virginianus) and mule deer (Odocoileus hemionius) were collected in 1968 and 1969 for a study of food habits. Rumen contents were analyzed by use of the point-analysis technique and weights. This is the first food habits study from the southern Black Hills and is necessary for proper deer management. To evaluate the suitability of the point technique for Black Hills vegetation, an artificial population was constructed from known weights of a forb, (Achillea lanulosa), grass (Oryzopsis asperfoliz), rose (Rosa sp.), kinnikinnick (Arctostaphylos uva-ursi), and ponderosa pine (Pinus ponderosa). Each population was tested with 100-point trails and 200-point trials. …

The Effects Of Acute Ammonia Toxicity On Certain Homogram Parameters In Sheep, William C. Kirkpatrick Jan 1971

The Effects Of Acute Ammonia Toxicity On Certain Homogram Parameters In Sheep, William C. Kirkpatrick

Electronic Theses and Dissertations

Due to the rapidly expanding human population, one of the greatest problems facing agricultural scientists is the development of adequate food resources to meet the growing demand for quality protein. The development of more economical and higher quality feed for ruminant animals is essential since they are one of man's primary sources of animal protein. Microorganisms in the ruminant stomach convert relatively cheap non-protein nitrogen compounds into bacterial proteins, which are digested, absorbed, and utilized by the host animal. Urea, a common non-protein nitrogen compound, is hydrolyzed into ammonia and carbon dioxide by bacterial urease. When urea is hydrolyzed faster …


The Use Of Iodine And Chlormadinone Acetate To Suppress Sexual Maturity In Chickens, Curtis Eldon Holmquist Jan 1971

The Use Of Iodine And Chlormadinone Acetate To Suppress Sexual Maturity In Chickens, Curtis Eldon Holmquist

Electronic Theses and Dissertations

Researchers, for several years, have tried various methods of retarding the onset of egg production in chickens. Some reports have shown that a delay in sexual maturity is beneficial. When comparing restricted pullets to unrestricted control groups, these reports reveal economic advantages of restriction in that restricted pullets have lower total feed costs, improved egg size, improved total egg production and a lower percentage of mortality during the production cycle. Other research has accomplished restriction with no resulting advantages. These discrepancies may be due, in part, to inaccurate means by which the results of restriction have been measured. Confinement rearing …


Various Forms Of Dehydrated Alfalfa In High-Concentrate Cattle Finishing Diets, Jerry D. Burkhardt Jan 1971

Various Forms Of Dehydrated Alfalfa In High-Concentrate Cattle Finishing Diets, Jerry D. Burkhardt

Electronic Theses and Dissertations

Even though growing and finishing beef cattle have been fed satisfactorily on all-concentrate diets, in many instances weight gains have been improved and management problems reduced by including some conventional form of roughage in the diet. The most efficient level of roughage will likely be a variable factor depending upon a number of things including weight and condition of the cattle and. nature of the roughages and concentrates. It is a well-established fact that .as the energy content of the diet increases the rate of gain increases and the feed required per unit of gain decreases. In addition to rate …


The Effects Of Erythropoietin, Dibenzyline, And Iron Dextran On The Hemogram Of Doe And Fetal Rabbits, Eugene Austin Gardner Jan 1971

The Effects Of Erythropoietin, Dibenzyline, And Iron Dextran On The Hemogram Of Doe And Fetal Rabbits, Eugene Austin Gardner

Electronic Theses and Dissertations

The iron deficiency anemia found particularly in swine has a high incidence in the newborn. The nutrition of the sow inversely affects progression of the anemia. Newborn nutritional status, also, inversely augments the anemic condition. The anemia does not become apparent in the newborn until a few days following parturition. There is a drastic decrease in iron availability with succeeding decreases in normal hemoglobin formation and mature red blood cell formation. An important factor along with these conditions is susceptibility to disease leading to death. A gradual return to normal follows if the newborn survives the anemic period. This condition …

An Evaluation By Winter Wheat Of Phosphorus Carriers And The Effect Of Different Carriers On Three Phosphorus Availability Indices, Charles C. Biggar

Electronic Theses and Dissertations

Various types of phosphorus fertilizers are being commercially produced and used. Due to the different properties of these phosphate materials, their ability to supply phosphorus may differ among South Dakota soil environments. To provide data for phosphate users it is necessary to evaluate- the.se materials under varying soil and climatic conditions. Soil reaction is commonly used to differentiate conditions within the soil that are important to phosphorus utilization or fixation. Generally, where fixation is high the possibility of utilization of the added phosphorus is low. Acid soils are considered as having a high phosphorus fixing capacity. Alkaline soils are medium …

A Study Of The Properties Of Parametric Programming, Arjun Kumar Batr

Electronic Theses and Dissertations

Programming is defined as the planning of activities for the sake of optimization. When linear constraints are ·assumed, together with a linear objective function, the optimization is defined as solving a linear programming problem. Linear programming was originally developed by Dantzig, Wood and (others for the U.S. Air Force. Since it was first published in 1947, it has been used widely in industrial as well as military situations.

Examples of specific exotic and straight forward applications of the linear programming technique can be found in text books, monographs and technical papers in the several fields in which it has been …


Classification Error Of Gaussian And Transformed Gaussian Variates, John E. Boyd Jan 1971

Classification Error Of Gaussian And Transformed Gaussian Variates, John E. Boyd

Electronic Theses and Dissertations

As indicated by the title and by the large proportion of pages devoted to the subject, transformation of variables is the primary topic of this thesis. The transformation of partially overlapping, correlated, two-dimensional, Gaussian distributed random variates to partially overlapping, independent, one-dimensional, Cauchy distributed random variates involves a reduction in dimensionality by one. Consequently, the equation defining the receiver is simplified, and the expressions for predicting the classification error are easier to formulate. The equation required to effect this transformation is z=Y1/Y2 , where Y1 , Y 2 are the standardized correlated Gaussian variates and z …

The majority of the grazing lands in the Northern Great Plains are native grasslands. In some areas profits derived from these grasslands may best be increased by complete renovation and reseeding. However, many of these grasslands can be improved by practices such as deferred grazing, interseedings, rotational grazing and fertilization. This study involves the evaluation of one of these practices, nitrogen and phosphorus fertilization. It is a study that is to provide basic information which can be used to determi.ne the economic feasibility of grassland fertilization.

The purpose of this study was (1) to determine whether significant yield increases could …


Partial Cooling Of The Environment In Free Stalls For Sows During Farrowing And Lactation, Thomas R. Gannon Jan 1971

Partial Cooling Of The Environment In Free Stalls For Sows During Farrowing And Lactation, Thomas R. Gannon

Electronic Theses and Dissertations

Many of the technological advances in the swine industry have resulted in increased capital requirements for buildings and equipment. This has made multiple farrowing, including summer farrowing, a near necessity. Hog farmers recognize the problem of sow mortality due to severe heat stress during periods of high ambient temperatures, and hog producers utilizing the free stall farrowing system recognize yet another problem, that of poor stall occupancy. Sows in this type of system tend to seek relief by leaving their stalls and lying in moist or breezy areas. This decreased stall occupancy has resulted in pigs being severely neglected, reduced …

Man And Nature In Herman Melville's "The Encantadas", Jay J. Jackson Jan 1971

Man And Nature In Herman Melville's "The Encantadas", Jay J. Jackson

Electronic Theses and Dissertations

It is in light of the fact that no critic has yet seen fit to explore "The Encantadas" with regard to Melville's theme of the man-nature dialectic that this thesis is written. It is the purpose of this paper to show how Melville views man, nature, and their relationship to each other within the bizarre setting of the Galapagos Islands. In no other work save Moby-Dick does Melville so deeply cut to the roots of the question of man and his role in the natural scheme of the cosmos. In order to examine the man-nature tension of "The Encantadas," I …
