Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
American systematics collections: A national plan. Developed by a stellar group of biologists including David Wake and Peter Raven, this plan called for action by the systematics community. The estimate of needs in 1973 called for about 63 million USD for the next five years just to keep the US National Collections from disintegrating and to get them in shape to mount the huge effort needed to fully inventory the biota of the earth (a plan that was not even dreamed of until about the year 1995).

Seasonal Food Habits Of European Wild Hogs (Sus Scrofa) In The Great Smoky Mountains National Park, Charles D. Scott
Masters Theses
This study was conducted on the Tennessee side of the Great Smoky Mountains National Park from the fall of 1971 to the spring of 1973. Seasonal food habits information of the European wild hog (Sus scrofa) was obtained by the analyses of stomach contents.
Hogs ate primarily plant material in all seasons. Grasses (Gramineae) were the most important food item in the spring. Grasses were important to hogs in the summer, as were the fruits of Gaylussacia sp., Vaccinium sp., and Malus sp. Roots were the major food item in the fall and winter months, although the mast …

Food Preservation Practices Used By Selected Homemakers In Hancock County, Tennessee, Doris Ellen Phillips
Masters Theses
Food preservation practices of Home Demonstration Club (HOC) and Expanded Foods and Nutrition Education Program (EFNEP) homemakers and environmental factors possibly influencing these practices were studied. An interview schedule was used.
As a combined sample, 96% of the HDC and EFNEP homemakers participated in some form of food preservation. The percentages of homemakers using the various methods of food preservation differed with over 50% canning, pickling, making jelly, and freezing.
Educational level, social participation score, and income were all higher for the HOC homemakers than the EFNEP women (P <0.01). Age of the homemaker and the number in the family were similar for the 2 groups.
The proportion of homemakers participating in the various forms of food …

The Effect Of Thermoradiation On Bacterial Spores In Wet And Dry Systems, Thomas J. David
The Effect Of Thermoradiation On Bacterial Spores In Wet And Dry Systems, Thomas J. David
Biology ETDs
Spores of Bacillus subtilis var. niger and Clostridium sporogenes were exposed to heat and radiation, separately, and in simultaneous combination. The spores were subjected to treatment under two sets of conditions. Wet spores were suspended in water during treatment, while spores in the dry state were treated in air which had a relative humidity of about 30% at room temperature. Treatment with ionizing radiation at room temperature was found to be more effective in the dry than the wet state, in contrast to most theories and some research in that area. Bacillus subtilis var. niger was more resistant to heat …

Rotationally Inelastic Molecular Scattering. Computational Tests Of Some Simple Solutions Of The Strong Coupling Problem, Thomas P. Tsien, Gregory A. Parker, Russell T. Pack
Faculty Publications
Partial cross sections (opacity functions) for rotational transitions in atom-diatom collisions are computed in the infinite-order sudden (IOS) approximation and compared with accurate close-coupling (CC) calculations. Agreement is good in the dominant coupling (small total angular momentum J) region. Simple methods for calculating integral inelastic cross sections are discussed, and it is found that accurate cross sections can often be computed very simply, even when large numbers of channels are coupled together, by using IOS or first-order sudden (FOS) approximations for small J and CC or exponential Born (EBDW) methods for large J.

Meeting The Protein Needs Of Growing And Finishing Cattle, William W. Schneider
Meeting The Protein Needs Of Growing And Finishing Cattle, William W. Schneider
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
The cost of nearly all feed commodities has sharply risen since one year ago. Those feed ingredients normally used as natural protein sources, however , have risen in cost much more dramatically than the roughages or the cereal grains used for animal feed. This substantial rise in cost of high protein feeds plus possible shortages of feed grade urea will force many cattle feeders to alter feeding and management practices used in the past. For example, recommendations in previous years frequently called for the use of soybean meal or soybean meal based supplements as the source of protein in growing …

Morphological And Physiological Factors Related To Yield Of Alfalfa, A. L. Foutz, Wallace Wilhelm, A. K. Dobrenz
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Several morphological and physiological factors were measured on clones of alfalfa (Medicago sativa L. ‘Mesa- Sirsa’) which displayed a wide range in SLW, leaflet weight and leaflet area. Apparent photosynthesis, dark respiration and post-illumination burst expressed as mg C02 dm-2hr-1 were not related to yield. However, when the rate of each factor was expressed on a whole plant basis (rate x leaf area per plant) , significant relationships were found with yield. Correlation coefficients between total apparent photosynthesis, total dark respiration, total post-illumination C02 burst and yield were r = .71*, r = .77* …

Effects Of Confinement Feeding Systems On Beef Cattle Production, R.D. Goodrich, J.C. Meiske, R.E. Smith, H.E. Henke
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
Several factors have stimulated interest in housing systems for feedlot cattle. Some of these factors are (1) the desire to eliminate problems associated with the use of bedding, (2) the desire to decrease the labor required for feeding, bedding and manure handling, (3) the need to develop effective pollution control measures and (4) the desire to know the effects that housing systems may have on the performance and carcass characteristics of feedlot cattle. The objectives of the trials reported herein were (1) to study the influence of housing systems on the performance of finishing steer calves and (2) to study …

Carcass Characteristics Of Bulls, Heifers And Steers As Influenced By Ration And Market Weight, Peter B. Smith, W.J. Costello, Peter J. Thiex, L.B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
High feed grain prices, a growing worldwide demand for animal protein, and increasing demand for lean, high quality beef make it imperative that beef volume and production efficiency increase. Because of high feed costs it is important to know how concentrate level in the ration and market weight influence production efficiency and carcass composition of different sex groups. The purpose of this study was to evaluate the effects of market weight and ration concentrate level on the quant itative and qualitative carcass traits of yearling bulls, bull calves, heifers and steers .

Investigation Of Western Yellow Pine (Pinus Ponderosa) Abortion, C. Cogswell, L.D. Kamstra
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
For a number of years, ranchers in western South Dakota have been of the opinion that pregnant cows will abort after the consumption of sufficient quantities of yellow pine (Pinus ponderosa) needles. Problem areas exist where the yellow pine is the predominant pine species. Incidence of pine needle abortion is particularly high in late winter and early spring after cows in the last trimester of pregnancy graze on the needles. Some ranchers, however, have experienced the problem throughout the year when cows in earlier stages of pregnancy have aborted. Retained placentas are frequently associated with the abortions. If true abortions …

Systematics And Evolutionary Relationships Of Spiny Pocket Mice, Genus Liomys, Hugh H. Genoways
Systematics And Evolutionary Relationships Of Spiny Pocket Mice, Genus Liomys, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Introduction
Spiny pocket mice of the genus Liomys are members of the rodent family Heteromyidae and together with the genus Heteromys form the subfamily Heteromyinae. Their geographic range extends from northern Sonora, in western Mexico, and southern Texas southward to the vicinity of the Panama Canal Zone. Within this area, members of the genus occur mainly in dry to arid situations being replaced in areas of rain forest and cloud forest by members of the genus Heteromys. The vernacular name for Liomys is based on the fact that many of their hairs have been modified in the form of …

Growing And Fishing Bulls, Heifers And Steers, P.J. Thiex, L.B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
Growth rate of an animal depends upon energy consumed in excess of that for maintenance, and the requirements increase as the animal grows and fattens. Male and female cattle differ in rates of growth and fattening, but changes may be brought about by castration. There still is some concern as to the effects of market weight and energy content of rations on weight gain, feed efficiency and carcass characteristics of feedlot bulls, heifers and steers. This experiment was conducted to study these factors. Bulls ( calves and yearlings), heifers and steers were fed to one of two final weight groups. …

Storage Methods And Protein Supplements For High-Moisture Ear Corn, W.S. Swan, L.B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
A high rate of gain can be obtained with growing and finishing cattle fed ear corn adequately supplemented with protein, minerals and vitamins. The cob portion of the ear furnishes more roughage than has been reported to result in optimum gains with minimum problems frequently associated with high-concentrate diets. Other roughages are not indicated with ear corn where high rates of gain are desired. Ear corn contains less protein than recommended in most diets for growing and finishing cattle. The low protein cob portion may not be an economical source of roughage in comparison to those considerably higher in protein …

Weaning Age And Management Systems For Fall Born Beef Calves, William Mccone
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
Seventeen registered Angus, Hereford and Shorthorn cows calved in September, 1972. The cows calved on pasture and remained on pasture until early November. From November 10 to December 29, the cows were bred for 1973 fall calves. On December 29, 1972, one-half of the calves were weaned and started on a self-fed ration. The remaining one-half of the calves were allowed to continue nursing the cows, but the calves also had access to a creep feeder containing the same ration used for the weaned calves. At the start of the experiment the calves were randomly divided by sex, breed and …
Adaptation Of Feedlot Cattle To Urea And Antibacterial Compounds, J.D. Burkhardt, L.B. Embry, L.B. Dye
Adaptation Of Feedlot Cattle To Urea And Antibacterial Compounds, J.D. Burkhardt, L.B. Embry, L.B. Dye
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
A period of adaptation to urea during which feedlot performance is suppressed is frequently experienced when this product is added to rations of cattle not previously, or recently, fed it. This effect appears more evident with levels of urea used when it forms a major part of total protein in the ration. Urea and antibiotics in combination are common additions to protein supplements or mixed rations. At usual levels for continuous feeding of antibiotics and safe levels of urea for the dietary conditions, the combination appears satisfactory and to offer the beneficial effects from these compounds after a suitable period …
Backgrounding Of Feedlot Cattle - Levels Of Grain On Pasture, L.B. Embry
Backgrounding Of Feedlot Cattle - Levels Of Grain On Pasture, L.B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
Utilization of appreciable quantities of roughage for growing and finishing feedlot cattle means some restriction on rate of production in comparison to that obtained from diets containing more liberal quantities of concentrates. Periods of restricted growth of cattle have been shown to be followed by an accelerated rate of growth with an improvement in feed efficiency in comparison to more liberally fed animals during later finishing periods with high-concentrate diets. Thus, there can be some compensation in both rate and efficiency of gain following periods of restriction. However, the amount of compensation may vary depending upon the comparative degree and …
