Responses Of Rumen Microflora To Whey Products Added To High-Grain Low-Roughage Rations, Virgil L. Metzger
Responses Of Rumen Microflora To Whey Products Added To High-Grain Low-Roughage Rations, Virgil L. Metzger
Electronic Theses and Dissertations
Many factors present in livestock feeds affect the numbers and types of protozoa and bacteria in the rumen. A small particle size of feed and a fast rate of passage of the feed through the ruminant decreases protozoal numbers. Full feeding of a concentrate ration and an acid pH in the rumen also tend to reduce protozoa numbers. Bacteria numbers tend to increase as the protozoa numbers decrease. Knowledge of rumen microflora population changes on different rations is lacking. It is known that restricted-roughage rations will generally cause lower protozoal numbers. Since whey is an available source of lactose and …
An Evaluation Of Variation In Soil Test Results Caused By Sampling Methods And Individual Samplers, Terensio Kokorom Opio
An Evaluation Of Variation In Soil Test Results Caused By Sampling Methods And Individual Samplers, Terensio Kokorom Opio
Electronic Theses and Dissertations
Soil sampling has been a subject of much study over the past years and has been undertaken for many different purposes. In the agricultural industry, soil sampling is undertaken mostly for the sake of evaluating soil fertility potentials to aid in making fertilizer recommendations. The need for better soil sampling is illustrated by the fact that inadequate sampling often leads to improper use of fertilizer by farmers. The samples are collected and brought to the soil testing laboratories where they are chemically analyzed for the main plant food elements. Fertilizer recommendations based on the soil test results may either be …

The Wooded Soils Of Southeast South Dakota : Their Morphology And Genesis, Ronald A. Torkelson
The Wooded Soils Of Southeast South Dakota : Their Morphology And Genesis, Ronald A. Torkelson
Electronic Theses and Dissertations
Southeast South Dakota has a macro-climate environment favorable to grass. It is a natural prairie area where moisture generally is limiting for trees unless natural landscape conditions shift the microclimate in a cool-moist directions. The Newton Hills area provides these special conditions. A dissected plateau with local relief measured in hundreds of feet slopes steeply in a northeasterly direction to the trench of the Big Sioux River. This northeast-facing slope escapes the direct rays of the sun and an environment more cool and moist than the adjacent prairie upland is formed. Relict trees have persisted in these areas and under …
A Comparison Of An Individualized English Program With A Traditional English Program In Desmet High School, Beverly Jean Wolkow
A Comparison Of An Individualized English Program With A Traditional English Program In Desmet High School, Beverly Jean Wolkow
Electronic Theses and Dissertations
With the incredible amount of information being uncovered each day and with the emphasis swinging from subject-centered curriculum to child-centered curriculum, education is in turmoil. Educators realize students cannot learn all the facts needed for the future. Since many people will have to retrain for new jobs several times in their lifetimes, students today probably cannot even learn enough for continuous occupation. To meet these challenges, educators have been searching for new methods of organization and instruction. One such method is individualized instruction. The purpose of initiating and studying a program of individualized instruction in English was to establish the …
A Two Year Study Of Potential Resistance In The Adult Western Corn Rootworm In South Dakota, John M. Wirtz
A Two Year Study Of Potential Resistance In The Adult Western Corn Rootworm In South Dakota, John M. Wirtz
Electronic Theses and Dissertations
The western corn rootworm Diabrotica virgifera Le Conte, and the northern corn rootworm Diabrotica longicornis Say, are major pests affecting corn in South Dakota. Jones (1968) considered the rootworm the number one corn pest in South Dakota and estimated that the rootworm caused fifty percent of all insect damage done to corn. Prior to 1961 the northern corn rootworm was the predominant species causing damage in South Dakota. The western corn rootworm is presently the predominant species (Nearman, 1968). Cultural and chemical control methods have been used to control corn rootworms in the past with varying degrees of success. Crop …

Electronic Theses and Dissertations
Sodium D-thyroxine was evaluated for possible embryotoxic and/or teratogenic effects following oral administration in New Zealand White rabbits. All animals utilized were alert, active and apparently disease-free virgin does weighing three and one-half to four kilograms. Rabbits were individually housed in stainless steel batteries and maintained on a commercially available palletized diet and mineral supplement. Feed and water were provided ad libitum in animal quarters air conditioned to minimize environmental temperature fluctuations. Following a 14-day post-delivery observation period does were bred to New Zealand White bucks and randomly allocated to one of two experimental groups or the control group each …
Selected Determinants Of The Hiring Policy Of Employers Relative To Businesses In Five Counties Of South Dakota, Don Martin
Electronic Theses and Dissertations
Description of the Problem For nearly everyone in our society, remunerative work has provided a meaningful role. It also provided an avenue for the attainment of respect, dignity, and the essentials of the "good life." On the other hand, unemployment has necessitated reliance on programs for the indigent and unemployed. The central focus of this study was the Janus-headed problem of unemployment and underemployment. The approach was oriented to a level of organization which has not previously been adequately explored. Unlike most of the studies which have attempted to meliorate the exigencies of unemployment, this study focused on the needs …

Electronic Theses and Dissertations
Six-to 8-months-old Hereford heifers categorized as grubby or grub-free calves were used for this research. Forty calves were purchased in 1968 and also in 1969. The grubby calves were obtained from Highmore, South Dakota, an area where calves have a history of heavy grub infestations of both Hypoderma bovis (L.) and Hypoderma lineatum (de Villers). The grub-free calves were purchased in Fargo, North Dakota. Calves raised in this area seldom are infested with cattle grubs. Specified groups of calves were subjected to 30 minutes of continuous exercise or the withholding of feed and water for 24 hours prior to treatment …
Plant Analysis Of Spring Small Grains At Different Stages Of Growth, James Henry Pfeifer
Plant Analysis Of Spring Small Grains At Different Stages Of Growth, James Henry Pfeifer
Electronic Theses and Dissertations
Plant analysis has developed into a diagnostic tool for measuring the nutrient status of crops. Plant analysis promises to greatly supplement the methods now available for estimating nutrient sufficiency, and as a result, increase the yield of crops. For small grains, the sampling time recommended for plant analysis is the reproductive stage ·of growth. This period has been used to determine nutrient concentrations of N, P, K, Ca, Mg, S, Zn, Mn, and Fe. Much concern exists with regards to the accuracy of plant analysis in predicting the nutrient status of small grain plants. Concern spring wheat, and barley under …

An Evaluation By Winter Wheat Of Phosphorus Carriers And The Effect Of Different Carriers On Three Phosphorus Availability Indices, Charles C. Biggar
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 …
Classification Error Of Gaussian And Transformed Gaussian Variates, John E. Boyd
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 …
