Effects Of Bacterial Inoculation Of Corn Silage On Feedlot Performance, Nutrient Utilization, Preservation And Aerobic Feedbunk Life, J. G. Nothnagel, R. M. Luther, L. F. Palmer, L. B. Embry

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1984

The making of quality silage is largely dependent upon the fermentation process as carried out by microorganisms present in the forage during ensiling. Research has shown that the number of these organisms can vary considerably in the corn forage. Inoculation of the forage with microorganisms favorable to fermentation such as Lactobacillus species is a means of reducing variation due to kind and number of fermentative organisms. Previous research at SDSU has shown there is very little difference in feedable corn silage quality with microbial inoculation, but that the fermentation process can be accelerated as fermentation temperatures were also observed with …

The Agricultural Trade And Economic Development Between The European Community And Maghreb Countries, M. Nidal Shaar

Economics Graduate Students Plan B Research Projects

A critical motivation of the post-war drive for European unification was the desire to change the bases for Europe's relations with the rest of the world in an era of dominance by extraneous continental super-powers and of the decolonization of its own nineteenth-century empires. The strategy adopted after the col lapse of the European Defense Community (EDC) of concentrating on economic integration, and assuming that its inevitable success would facilitate political unification, left the European communities with few instruments for the pursuit of external policy. Even within the economic sphere joint methods of pol icy formation have only fully superceded …

Range Renovation, F. R. Gartner, E. M. White

South Dakota Cow-Calf Field Day Proceedings, 1984

Mechanical treatments of rangelands are designed to increase water infiltration and increase forage quantity and quality. Storing precipitation where it falls is important to stabilize in annual forage production, especially on sites with water uptake problems due to slope, shortgrass sod cover and/or high salt concentrations in the upper horizons
Soil moisture and vegetation data accumulated over five growing seasons following mechanical renovation of Thin Claypan range sites indicate a great potential exists for increasing range carrying capacity. Both soil moisture and forage production can be improved.

Effect Of Breed Group And Mating System On Weaning Production In Beef Cattle, M. D. Monfore

South Dakota Cow-Calf Field Day Proceedings, 1984

Straightbred Hereford, Angus-Hereford and Simmental-Hereford are popular cow breeds in South Dakota. Larger and/or higher milking crossbreds can be expected to require more energy input to support higher maintenance and lactation requirements. Realizing this, comparisons between breed groups and mating systems under realistic conditions are of interest to producers. This study was designed to evaluate how straightbred Herefords along with Simmental-Hereford and Angus-Hereford two-breed rotations perform under western South Dakota range conditions. All cattle were maintained at the Antelope Range Livestock Station near Buffalo, South Dakota, throughout the study.

Abundance, Biomass, And Diversity Of Aquatic Invertebrates In Level Ditches And Adjacent Natural Emergent Marsh In An Eastern South Dakota Wetland, Michael R. Broschart

Electronic Theses and Dissertations

The aquatic invertebrate communities of level ditches and adjacent natural emergent marsh in a South Dakota prairie wetland were sampled during the summer of 1982. Collections were made in both the water column and the bottom substrates. Forty-five taxa were collected. Analysis of variance indicated that a significantly greater mean number of taxa and a larger mean number of all macroinvertebrates were present in level ditches than in the natural emergent marsh. No differences were detected for mean biomass of all macroinvertebrate taxa collectively. Several taxa had a greater mean number and biomass in the level ditches than in the …

Factors Affecting Water Quality And Microinvertebrate Distribution Within A Small Black Hills Stream, Henry G. Drewes

Electronic Theses and Dissertations

A comparative evaluation of the benthic macroinvertebrate fauna was conducted concurrently with a physiochemical investigation on Slate Creek, Pennington County, South Dakota in the Black Hills. Water quality differences between years and among stations were detected in Slate Creek from both physiochemical and macroinvertebrate evaluations. The primary sources of disturbance to the Slate Creek study site during the sampling period were landscaping activities within the Deerfield Park Resort development and livestock activity. Increased runoff and elevated stream flows in 1982 were responsible for the variation in water quality between years. Water quality differences among stations indicated significantly (P < 0.05) higher turbidity and temperature immediately below the development site in 1981 and 1982. Significantly (P < 0.05) higher fecal coliform bacteria counts were observed at station 5 for both years, resulting from increased livestock activity. Phosphates and nitrates were highest at stations 4 and 5 but were not significantly (P > 0.05) different …

The Manufacture Of Cheddar Cheese Using Vacuum Concentrated Milks, Charles A. Bemis

Electronic Theses and Dissertations

The United States (US) cheese industry has grown rapidly in the past decade. From 1971 to 1981, milk fat utilization for cheese manufacture increased from 17.7 to 27.6% of the total US milk fat supply, accompanied by a 49% increase in sales of cheese per capita (34). Offsetting substantial increases in sales and prices for cheeses, there have been marked increases in the cost of labor, energy, waste treatment, raw materials, and equipment. Hence, the manufacturers are realizing narrower profit margins. As a survival mechanism, cheesemakers have sought to maximize cheese yields per unit of milk, since increases in cheese …

Selenium And Arsenic Interaction In The Rat, Cecile Younan Andraos

Electronic Theses and Dissertations

Selenium was discovered by Berzelius and Gahn in 1817 while they were examining the sediment from a sulfuric acid plant at Gripsholm, Sweden. However, it was not until 1929 that the greatest interest in selenium and its compounds was aroused in relation to its toxic effects in the animal body. At that time, Franke at the South Dakota Experiment Station and other workers discovered that selenium was the toxic agent causing "Alkali disease", a chronic poisoning that affects livestock raised in certain areas of the Great Plains of the United States. It was found that certain plants could take up …

Biological And Chemical Analysis Of Echinacea Pallida (Nutt.) Nutt. With Emphasis On The Insecticidal Component, Gregory A. Bame

Electronic Theses and Dissertations

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 …

The Efficiency Of Four Selection Schemes For Improvement Of Cold Tolerance And Disease Resistance In Maize, Andrew Rocholl Bettendorf

Electronic Theses and Dissertations

The economic worth of any individual (plant or animal) is usually dependent on more than one trait. Since there is usually more than one trait involved in selection, a breeder’s problem is determining the relative importance of each of these traits. They must then be placed in some logical order so that the best material is selected for the following generations. Arriving at reasonable economic weights for each trait may be fairly difficult, especially if not much is known about the material one is working with. other factors to consider when selecting within a population are, how heritable the trait …

The Effects Of Climate On Total Digestible Nutrient Consumption Of The Cow And Calf And Cow Efficiency, David G. Boom

Electronic Theses and Dissertations

Animal productivity is a function of energy intake and heat production. The body core temperature must remain relatively constant and this is accomplished by regulating the balance between heat gain and heat loss. If, due to climatic stress, more energy is needed to maintain homeothermy, less energy is available for production. The range of ambient temperatures in which the animal can maintain homeothermy without increasing its rate of heat production is the zone of thermal neutrality. The lower border of the zone of thermal neutrality is the lower critical temperature. Temperatures below this zone cause the animal to immediately increase …

An Epidemiological Study Of Listeria Monocytogenes Using Virulence, Agglutination, And Agglutinin Adsorption Techniques, James R. Hoffman

Electronic Theses and Dissertations

The serological characterization of Listeria monocytogenes apparently began with the work by Seastone, who determined that a close serological relationship existed between cultures collected from humans and animals. Schultz et al. and Julianelle et al. later suggested that two serological types existed that could be connected to the origin of the strain. These initial studies were expanded by the work of Paterson, who studied the antigenic structure of Listeria monocytogenes using agglutination and adsorption techniques. Paterson studied somatic and flagellar antigens. The somatic antigens were prepared by growing bacteria on 1% glucose agar at 37°C for 18 h, removed with …

Forage Production And Utilization Systems For Cow-Calf Beef Production, Muftah M. Imsalem

Electronic Theses and Dissertations

Native grasslands in South Dakota are extremely variable and have steadily declined in condition. Pasture techniques are currently available to modify vegetation composition and productivity to bring about higher yields. Development of pasture systems that increase forage production is of a major importance in South Dakota. Fransen found that tame pastures and interseeded native range produced more gain per hectare than native range. The average daily gain of the cattle dropped severely at the end of the season in native and native-interseeded range. However, the tame pastures required substantial inputs in terms of fertilizer nitrogen. The purpose of this study …
