Fertilization Practices For Double Cropping Systems, John H. Grove

Agronomy Notes

Double cropping has become an important practice in the state of Kentucky. While the wheat-soybean grain intensive production system is the most widely used on an acreage basis (approx. 3/4 million acres per year) several other systems are being adopted by Kentucky growers. Most of these involve some silage production for beef and/or dairy cattle. The fall seeded small grain (wheat, barley, triticale) is harvested at an immature stage of growth and ensiled and a subsequent crop for silage (corn, grain sorghum) or grain (soybean, grain sorghum) is planted. The use of reduced and no-tillage management will speed up planting …

Swine Marketing In South Dakota: Results Of A Producer Survey, Larry Janssen, Kevin K. Weischedel

Economics Research Reports (1969 - 2017)

South Dakota is one of the top 10 hog production states with about 3 m111ion hogs and pigs marketed and 3.2 million hogs slaughtered in the state each year. This totals 3-4 percent of the nation's hog supply. With ample supplies of available land, labor, and feed grain there is considerable potential for further growth of the South Dakota pork industry if the expansion can be based on profitable production and marketing prospects for producers. In 1980, a pork marketing study was initiated by SDSU to obtain current infonnation on: 1) Organization of hog production and marketing in South Dakota, …

The Effects Of Dredged Materials On The Copeod, Acartia Tonsa, Renee Suzanne Crouch

Biological Sciences Theses & Dissertations

A study was conducted to determine the potential impact of open ocean disposal of sediments dredged from a highly industrialized seaport. Sediments from three potential dredge sites along the Southern Branch of the Elizabeth River, Hampton Roads, Virginia were evaluated for acute toxicity. The suspended particulate fractions of dredged materials were tested in a series of 96-hour, static bioassays using the calanoid copepod, Acartia tonsa Dana. Significant mortalities were observed for all three sites with the sediments from the most heavily industrialized site producing immediate and severe mortality. Analysis of results indicates that mortality was highly related to the volatile …

The Effect Of Sea Nettle Abundance On The Food Chain Of The Lower Chesapeake Bay, Michael Glenn Kelly

OES Theses and Dissertations

The significance of sea nettle abundance on lower levels of the Chesapeake Bay food chain was examined in a field study and by the analysis of medusa gut contents. In the field study, the abundance of four levels of the food chain (Chlorophyll (a), copepods, the ctenophore Mnemiopsis leidyi, and the Schyphomedusa Chrysaora guinguecirrha) were monitored twice weekly at four stations from May 10 through September 30, 1982. The copepod standing stock declined sharply in late May when M. leidyi appeared, but rebounded a month later when C. guinguecirrha medusae reduced the ctenophore population. Despite the additional presence …

Evaluation Of Dimethyl Anthranilate As A Nontoxic Starling Repellent For Feedlot Settings, J. Russel Mason, Adam H. Arzt, Russel F. Reidinger

Wildlife Damage Management Conference

Few objective estimates are available, but starling (Sturnus uulgaris) and, sometimes, blackbird (e.g., Agelaius phoeniceus) depredations at feedlots are considered serious economic problems (Besser et al. 1967, 1968; Feare 1975, 1980; Stickley 1979; Twedt and Glahn 1982). Losses may result either from feed contamination and disease transmission or, more likely, from feed consumption (Besser et al. 1968; Russell 1975; Twedt and Glahn 1982). These problems are exacerbated by the use of complete diets (Rickaby 1978) which are presented in open troughs to which starlings have access. Feare and Wadsworth (1981) have shown that these birds can take …

Wildlife Population Cycles: Implications For Damage Control Planning, Richard E. Griffiths

Wildlife Damage Management Conference

Animal population cycles are not a newly discovered phenomena. References to irruptions (sic, Leopold 1933 p. 50) of small rodents can be found in the Old Testament, the writings of Aristotle and in European histories (Orr 1963 p. 360). The wildlife literature is filled with descriptions and studies of the population fluctuations of numerous species. Despite the vast amounts of data collected and speculation engaged in, biologists only partially understand the reasons for these fluctuations (Archibald 1977, Chitty 1952, Christian 1950, Cole 1951, Frank 1957, Hoffman 1958 Swinton 1883 and many others).

Comparison Of 8 Physical Barriers Used For Protecting Douglas-Fir Seedlings From Deer Browse, David R. Deyoe, Wieger Schaap

Wildlife Damage Management Conference

The success or failure of forest regeneration efforts in western Oregon and Washington often depends on adequate control of animal damage to young seedlings. Cutover and partially stocked forest lands provide excellent habitat for animals that clip or browse young seedlings. Black and Dimock (1969) estimated that animals were responsible for roughly one out of five reforestation failures. The Cooperative Animal Damage study of coniferous plantations in Oregon and Washington (1963-1975) found that animals damaged an average of 30 percent of all unprotected Douglas-fir seedlings each year on the 165 plots studied (Black et al. 1979). Browsing by deer and …

Heat Tolerance Screening Of Field-Grown Cultivars Of Kentucky Bluegrass And Perennial Ryegrass, D. D. Minner, P. H. Dernoeden, David J. Wehner, M. S. Mcintosh

Office of the Dean (CAFES) Scholarship

The quality of cool-season turfgrasses frequently declines during periods of high temperature stress. Simple tests are needed to rapidly identify heat tolerant germplasm for incorporation into breeding programs. Facilitative screening tests have been devised, however, in the few studies that have been performed only immature and greenhouse or growth chamber-grown plants have been evaluated. To be of practical value, results of screening tests, employing plants grown under artificial conditions, should correlate closely with results of tests involving field grown plants. The objective of this research was to evaluate the heat tolerance of several cultivars of Kentucky bluegrass (Poa pratensis …

The Zinc Status Of Pregnant Vegetarian Women, Michelle J. Abu-Assal

Loma Linda University Electronic Theses, Dissertations & Projects

The zinc status of twelve lacto-ovo-vegetariah pregnant women and seventeen non-vegetarian pregnant women was evaluated. Zinc intakes were calculated from three-day dietary records and twenty-four hour dietary histories. Plasma zinc levels were drawn during the last trimester of pregnancy and approximately ten weeks postpartum. Gestational age at birth, birthweight, and APGAR scores of the infants born were obtained from the medical charts. Dietary zinc intakes for the vegetarians (10.5 ± 4.0 mg) did not differ significantly from the intakes of the non-vegetarians (10.9 ± 3.0 mg). The vegetarian last trimester plasma zinc levels (47.9 ± 12.4 mcg/dl) and postpartum plasma …

The Distribution And Morphology Of Fucus Distichus In An Estuarine Environment And The Effect Of Selected Ions On The Uptake Of Inorganic Carbon And Nitrate, Dale Howard Robinson

Dissertations and Theses

The morphology, distribution, and habitat of dwarf and normal forms of Fucus distichus in Nehalem Bay were examined. The dwarf form lacked the holdfast and sexual structures of the normal form and was more highly branched. Examples of the dwarf form were found growing as outgrowths of fragmented normal forms indicating that both forms are the same species. The normal form occurred attached to rocks near the mouth of the bay in waters of oceanic salinity. The dwarf form occurred as a free-living form in the salt marshes and in waters of lower salinity. These observations suggested that the occurrence …

Behavior, Habitat Use, Food, And Foraging Efficiency Of Three Species Of Sympatric Merons (Egretta), Donald M. Kent

USF Tampa Graduate Theses and Dissertations

The foraging ecology and behavior of Little Bule Herons (Egretta caerulea), Snowy Egrets (E. thula), and Tricolored Herons (E. tricolor) was studied from October 1981 to August 1982 in Old Tampa Bay and Safety Harbor, Hills borough and Pinellas Counties, Florida. Little Blue Herons foraged exclusively by walk-slow and employed head sways or tilted during 75% of the observations. Snowy Egrets used stand, walk-slow, disturb-and-chase, and foot-stirring. Tricolored Herons used stand, walk-slow, disturb-and-chase, ana stand-and-chase. Tricolored Herons using stand-and-chase stood near shore facing open water and when prey was spotted they ran or hopped in the direction of the prey …

Interaction Of Nutrition And Infection: Effect Of Zinc Deficiency On Immunoglobulin Levels In Trypanosoma Musculi Infection, Clarence Lee, Patricia Humphrey, Georgiana Aboko-Cole

Department of Biology Faculty Publications

Accumulative evidence in the scientific literature relating malnutrition and susceptibility to infection in human beings and animals has contributed significantly to the understanding of the maladies among the malnourished of the world. In the dispensation of health care systems around the world, little or no emphasis has been placed on trace-element nutrition. This paper adds to the available evidence by using a metabolic imbalance technique to investigate the effects zinc deficiency exert on the course of a parasitic infection. A model composed of zinc-deficient mice and Trypanosoma musculi was used to study changes in serum immunoglobulins.

Determination Of Erythrocyte Zinc Concentrations Using Zeeman Effect Atomic Absorption Spectroscopy, Tanya Maranda Lewis

Chemistry & Biochemistry Theses & Dissertations

The purpose of this research project was to develop assay procedures for determination of zinc in erythrocytes. Three methodologies were developed. The methods were evaluated on the basis of within-run and between-run precision. The most reproducible method, the 213.856 nm flame methodology, was used to determine red blood cell zinc concentrations in more than 200 samples obtained from the Neonatal Intensive care Unit at the Children's Hospital of the King's Daughters.

This study demonstrated that erythrocyte zinc levels in premature infants were similar to those of healthy adults. A linear relation between plasma and red blood cell zinc concentrations was …

The Effect Of Crowding On Growth Of The Cichlid Fish, Oreochromis Mossambicus, Bonnie A. Barrows

OES Theses and Dissertations

It has been reported that the Java tilapia, Oreochromis mossambicus, displays hypersensitivity to a substance it produces when biomass levels in a flow-through culture system exceed 20 g/1, resulting in reduced growth and high mortality. Experiments on the growth of this species in small tanks were conducted in order to determine whether O. mossambicus produces a growth-inhibiting compound under crowded conditions. This species was successfully maintained at biomass levels of 38 g/1 and 57 g/1 with a total mortality of only 4.5%.

The Java tilapia can grow rapidly in small aquaria, as indicated by the data taken during Experiment …

N:S Ratio Of Forages In Kentucky, Kenneth L. Wells

Agronomy Notes

Concern has been expressed during recent years that sulfur may have become more limiting for plant growth and subsequently ruminant animal nutrition than was expected. This likelihood is based largely on the fact that (a) the inherent sulfur content of fertilizer phosphates has greatly diminished with declining use of normal superphosphate in manufacture of mixed fertilizers, (b) increased regulatory effect on burning of high sulfur fuels, and (c) increased use of nitrogen fertilizers for production of animal feeds. Assumedly, any or all these factors could result in alteration of nitrogen and sulfur content of forages to the point that either …

The Copper Status Of Vegetarian And Non-Vegetarian Men, Susan Bruce

Loma Linda University Electronic Theses, Dissertations & Projects

In this study, the copper status of 18 vegetarian and 17 non-vegetarian men were compared. Copper status was assessed by determining red blood cell superoxide dismutase (RBC-SOD) activity and plasma copper. Plasma copper levels were measured by atomic absorption spectroscopy. Plasma cholesterol, triacyclglycerols, HDL cholesterol, LDL cholesterol VLDL cholesterol were also determined. Twenty-four hour recalls and three-day food records were obtained to determine copper, zinc, energy, protein, fat, fiber, saturated fat, oleic acid, linoleic acid and cholesterol intake. Non-vegetarians had a significantly higher plasma cholesterol and LDL cholesterol than vegetarians. They also had a significantly higher cholesterol, saturated fat, percent …

Aspects Of The Biology Of The Spotted Seatrout, Cynoscion Nebulosus, In Mississippi, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

About 3,000 specimens of the spotted seatrout from Mississippi Sound and adjacent water grouped by males and females had a nearly identical standard Iength (SL) versus total length (TL) relationship, although the equation for males in winter differed from that for those in other seasons. When investigating the SL-weight relationship, some differences occurred both among seasons and between sexes. Therefore, condition coefficients (K) were calculated to compare male and female groups according to their length and state of maturation on a seasonal basis. The hepatosomatic index (HSI) tended to increase with fish length, with relatively high values occurring in winter …
