Evaluation Of Urea And Dried Whey In Diets Of Cows During Early Lactation, David Paul Casper

Electronic Theses and Dissertations

Previous research indicated that soluble nitrogen may be utilized more efficiently for rumen microbial production in diets containing dried whey. To further evaluate this, 33 Holstein, cows (30 multiparous and 3 primiparous) were fed one of three concentrate mixes containing all natural proteins (SBM). 1% urea (U), or 1% urea and 30% dried whey (UDW) from wk 3 through 16 postpartum. Urea replaced portions of the soybean meal in the SBM mix while dried whey replaced portions of the corn and soybean meal. Cows were fed total mixed rations consisting of 40% (dry matter basis) corn silage, 10% alfalfa hay, …

The purpose of this study was to compare two training programs on male Reserve Officers Training Corps students as it is related to a passing score on the Army Physical Readiness Test.

The subjects were sixteen volunteer students who were randomly placed in two groups, formal and informal. Both groups were given a pretest, before beginning the study, to determine if they were equal.

The subjects in both groups trained for four weeks to prepare for the Army physical fitness test. Each group trained three times a week during the training period. The formal group's training was restricted to performing …

Bobwhite Thesaurus, Thomas G. Scott

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

The Bobwhite Thesaurus was assembled with the belief that it  would make the voluminous literature more accessible. Publications  on the bobwhite have become so numerous and have been published  in so many different places that today's bobwhite researcher is seldom able to conduct the library search required to unearth all pertinent material. This results in failure to acknowledge and use prior  findings.

An effort has been made to seek out and index all publications  issued prior to 1983 that contain information on the bobwhite. All  publications found have been included irrespective of their apparent  worth excepting anonymous papers. Publications which …

The Analysis And Use Of Methodologies For The Study Of The Diets Of Long-Eared Owls From Three Environments In North Central Oregon, John M. Barss

Dissertations and Theses

Part I of this study presents a procedure for standardization of pellet analysis methodologies which improves estimation of prey biomass and determines the number of pellets needed to estimate prey diversity indices. The procedure was developed to provide a simple, easily replicated methodology for the study of pellets which also retains maximal data recorded from pellet analysis. A sample size of ten Long-eared Owl pellets was found adequate to calculate diversity indices with no significant loss of accuracy when compared to total pellets recovered from beneath a roosting site. Analysis of the total sample of pellets from a specific roost …

Scanning Electron Microscopy In Retinal Research, Bessie Borwein

Scanning Electron Microscopy

The literature on scanning electron microscopy (SEM) pertaining to the retina has been surveyed and described.

The first two papers on SEM and retina appeared in 1969. Most of the earlier studies concentrated on descriptions [by SEM alone, or with light microscopy (LM) and transmission electron microscopy (TEM)] of the appearance of various retinae and retinal cells [fish, newt, primates, rodents and rabbits, bullfrog]; or embryology of the chick retina. Two papers dealt with retinal disease. In all there were 25 papers in SEM/retinal research before and in 1974. Since 1975 there have been 111 papers which have used SEM …

The Role Of The Salivary Glands In Uptake Of Fluoride In Teeth And Bone, Robin E. Vance

Loma Linda University Electronic Theses, Dissertations & Projects

The cariostatic capability of fluoride is generally recognized, in addition, it may also have a beneficial effect on bone. Fluoride is thought to exercise its cariostasis through a local effect on teeth, however, the possibility exists that fluoride exerts its action through a systemic mechanism. Fluoride uptake by rat teeth and its effectiveness as a cariostatic substance was studied in parotidectomized, submaxillariectomized, and totally sialoadenectomized animals (both parotid and submaxillary glands removed). The uptake of fluoride in bone was also quantitated for comparison purposes.

Rats were injected daily with 15 micromoles of fluoride dissolved in 0.1 ml saline. The rats …

Temperature-Dependent Model For Sorghum Midge (Diptera: Cecidomyiidae) Spring Emergence, Frederick P. Baxendale, G. L. Teetes, P. J. H. Sharpe

Department of Entomology: Faculty Publications

A temperature-dependent, two-component model, based on constant-temperature development data, was formulated which described the emergence of overwintered sorghum midges, Contarinia sorghicola (Coquillett) in the field. The first model component used a poikilotherm rate equation to predict emergence rates as a function of temperature. The second component distributed emerging adults over normalized time using a temperature- independent cumulative Weibull distribution. When coupled, components formed a temperature-dependent simulation model which described the spring emergence of overwintered midges from 1979 to 1982. The model tended to predict emergence before it actually occurred in the field. This discrepancy was corrected by incorporating a 1.27-cm …

Scanning And Transmission Electron Microscopic Studies On The Oviducts Of Pekin Ducks Fed Methyl Mercury Containing Diets, A. Balachandran, M. K. Bhatnagar, H. D. Geissinger

Scanning Electron Microscopy

This study was undertaken to examine the effects of varying levels of methyl mercury (MeHg) on the ultrastructure of the surface epithelium of the oviduct of ducks. Accordingly, Pekin ducks were maintained on feed containing varying doses of (0.0; 0.5; 5.0; 15.0 ppm) of MeHg (Group I - control to IV) for 12 weeks and sacrificed. Tissue from the magnum and the shell gland regions of the oviduct was processed for scanning electron microscopy (SEM) and transmission electron microscopy (TEM). It was found that the primary and secondary folds of these regions of the oviducts of the control and 0.5 …

Isolation Of Lactoferrin And Its Concentration In Sows’ Colostrum And Milk During A 21-Day Lactation, J. I. Elliot, B. Senft, G. Ernhardt, D. Fraser

Nutrition Collection

Levels of lactoferrin, an Fe-binding protein with bacteriostatic properties, were determined in the colostrum and milk of Yorkshire sows during a 21-d lactation. Lactoferrin levels averaged 1,100 to 1,300 μg/ml near the time of farrowing, then declined sharply during the first week of lactation. Concentration of lactoferrin showed considerable variation among sows, but not among teat positions (anterior to posterior). A method for isolating high purity swine lactoferrin is described.

Grass Tetany, Paul Q. Guyer, Alex Hogg, Gene White

University of Nebraska-Lincoln Extension: Historical Materials

Grass tetany is a nutritional or metabolic disorder in cattle characterized by low blood magnesium, yet it is not just a simple magnesium deficiency. It is also called grass staggers, wheat pasture poisoning and hypomagnesemia. It primarily affects older cows nursing calves under 8 weeks of age, but may also occur in young or dry cows and growing calves. It happens most frequently when cattle are grazing lush, immature grass, but occasionally occurs when cattle are fed dry forages (winter tetany).

Acute Effects Of Phenytoin And Thioridazine, Alone And Combination, Upon Water Intake And Body Weight Changes In Rats, Miriana Witzig-Krstic

Extrathyroidal Human Biochemistry Of Monoiodotyrosine, Stanley Andrew Tan

Loma Linda University Electronic Theses, Dissertations & Projects

The existence of extrathyroidal monoiodotyrosine (MIT) has been debated because of uncertain results from measuring serum MIT. The reason is that the isotopic and chromatographic assays used have not been sensitive enough. This investigation undertook to establish the existence of MIT in serum utilizing a radioimmunoassay (RIA), to study the physiology of serum MIT, and to discover the pharmacologic effects of exogenous MIT.

MIT-binding antibody was raised in rabbits by immunization with an MIT-porcine thyroglobulin conjugate. The antiserum bound 40% of the labeled MIT at a final dilution of 1:1000. Incubation of 100 µ1 antiserum with 50 pg [^{125 …}

Age-Related Changes Of Neurites In Meissner Corpuscles Of Diabetic, Vicky R. Ras

Loma Linda University Electronic Theses, Dissertations & Projects

This thesis is based on a qualitative and quantitative study of the neural component of Meissner corpuscles of diabetic and non-diabetic mice. Age-related changes were also documented in these mechanoreceptors. Corpuscles from forty-six diabetic mice and forty-six non-diabetic mice ranging from 2.5 to 17 months old were studied. Forepaw index digital pads were formalin-fixed and frozen-sectioned parallel to each digit and perpendicular to the skin. Serial sections were then silver-impregnated to allow light microscopic examination of the neurites in the corpuscles.

Neurites became more coarse, tortuous, branched, varicose, and thus more complex until middle age. Corpuscle size appeared greatest at …
