G97-1334 Estimating Manure Nutrients From Livestock And Poultry, Richard K. Koelsch, Charles A. Shapiro

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses a procedure for estimating the quantity of nutrients in livestock manure. When managed properly, nutrients in livestock manure can be a valuable resource. When managed improperly, however, these same nutrients become a potential environmental pollutant. Accurate crediting of manure nutrients within a total crop nutrient program is fundamental to utilizing manure as a resource. This NebGuide will help producers estimate the total manure nutrients (N, P and K) produced by their livestock and show how to adjust for losses for various storage and handling situations.

A Novel Iron-Regulated Metal Transporter From Plants Identified By Functional Expression In Yeast., David Eide, Margaret Broderius, Jeanette Fett, Mary Lou Guerinot

Dartmouth Scholarship

Iron is an essential nutrient for virtually all organisms. The IRT1 (iron-regulated transporter) gene of the plant Arabidopsis thaliana, encoding a probable Fe(II) transporter, was cloned by functional expression in a yeast strain defective for iron uptake. Yeast expressing IRT1 possess a novel Fe(II) uptake activity that is strongly inhibited by Cd. IRT1 is predicted to be an integral membrane protein with a metal-binding domain. Data base comparisons and Southern blot analysis indicated that IRT1 is a member of a gene family in Arabidopsis. Related sequences were also found in the genomes of rice, yeast, nematodes, and humans. In Arabidopsis, …

Differential Role Of The Endothelium In Regulating Microvascular Blood Flow, Tao Tang

Electronic Theses and Dissertations

The vascular endothelial cell (EC) plays an important role in regulating vascular tone and local blood flow by sensing chemical and mechanical stimuli on the vascular wall and releasing a host of vasoactive substances upon activations of endogenous or exogenous vasoactive substances. The central hypothesis is that local control of blood now and autoregulatory behavior in the microcirculation is distinctive at different levels of the vasculature and is dependent on the cellular activities of the EC and its interaction with the local environment. The in vivo as well as the ex vivo, flow-controlled preparations of the hamster cheek pouch were …

G94-1231 Harvesting Corn And Sorghum For Silage, Rick Grant, Rick Stock

University of Nebraska-Lincoln Extension: Historical Materials

This publication describes how to make high-quality corn and sorghum silage.

Quality Silage

Silage feeding quality is determined by 1) the nutrient content of the crop stored, 2) the stage of maturity and moisture content when harvested and 3) the effectiveness of silage preservation.

Moose (Alces Alces L.) Browsing In Young Scots Pine Stands In Relation To The Characteristics Of Their Winter Habitats, Risto Heikkila, Sauli Harkonen

Aspen Bibliography

Moose (Alces alces L.) browsing was studied in young Scots pine (Pinus sylvestris L.) stands mixed with deciduous trees in high-density winter ranges. The proportional use of twig biomass decreased as the availability increased. The total as well as proportional biomass consumption were higher on the moist than on the dry type of forest. The per tree consumption of pine was higher on the moist type, where the availability of pine was lower. Deciduous trees were more consumed on the moist type, where their availability was relatively high. The consumption of pine saplings increased as the availability of …

Changes In Intracellular Chloride During Osmotic Stress And L-Alanine Uptake In Mouse Hepatocytes, Kening Wang

Electronic Theses and Dissertations

A stable intracellular ionic environment is necessary for hepatocytes to function normally. Thus, during hypotonic shock or L-alanine uptake, hepatocytes swell and then exhibit a regulatory volume decrease (RVD), which comprises an increase in K$\sp+$ conductance (G$\sb{\rm K}$), an increased K$\sp+$ efflux, and a hyperpolarization of transmembrane potential (V$\sb{\rm m}$). Since hepatocyte intracellular Cl$\sp-$ has been demonstrated to distribute passively with V$\sb{\rm m}$, this study is designed to test the hypothesis that the hypotonic shock- or L-alanine uptake-induced hyperpolarization of V$\sb{\rm m}$ might provide an electromotive force for the efflux of hepatocyte intracellular Cl$\sp-$, which in turn would contribute osmotically …

G89-919 Quality Laboratory Samples Necessary For Accurate Disease Diagnosis, Duane Rice, Douglas G. Rogers

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the importance of submitting proper specimens to the veterinary diagnostic laboratory as an aid in diagnosing infectious diseases, feed imbalance, or animal poisoning.

To comprehend the reasons for failures in disease diagnosis at veterinary diagnostic laboratories, it is important to understand what disease is, what causes disease, how the animal resists disease (becomes immune), and what happens to the animal if disease develops and the animal does not become immune.

According to Stedmans Dictionary, disease is an interruption, cessation or disorder of body functions, systems or organs. Some diseases may be obvious to the untrained eye, …

Effects Of Macrocyclic Trichothecene Mycotoxins On The Murine Immune System, Brian J. Hughes

Biology

The macrocyclic trichothecenes are a unique group of toxins which have some antileukemic properties. In the first study, verrucarin A and roridin A were examined. Both mycotoxins were administered intraperitoneally at an equitoxic dose of 0.35 mg/kg to CD-1 mice. Lymphocyte proliferation was studied on days 2, 4, and 7 after animals were dosed with verrucarin A. After day 2, no differences in ³HThymidine (³H-TdR) incorporation were observed using concanavalin A (Con A), phytohaemagglutinin (PHA), pokeweed mitogen (PWM), or lipopolysaccharide (LPS). On day 4, DNA synthesis induced by Con A, PHA, and PWM increased significantly. On day …

Comparative Study Of Pituitary-Thyroid Hormone Economy In Fasting And Hypothyroid Rats., Donald L. St Germain, Valerie A. Galton

Dartmouth Scholarship

Starvation in laboratory rodents results in significant alterations in thyroid hormone economy characterized by decreased circulating levels of thyroxine (T4) and 3,5,3'-triiodothyronine (T3) and a decline in serum thyrotropin (TSH) concentration. To investigate this apparent paradox, we have compared in fasted and hypothyroid animals the intracellular parameters mediating thyroid hormone action in the anterior pituitary gland. In vitro saturation analysis combined with quantitation of nuclear T3 content by radioimmunoassay allowed for characterization of pituitary nuclear T3 receptors and estimation of the endogenous fractional receptor occupancy. In rats, thyroidectomized 4 wk earlier, the 10-fold increase in serum TSH levels and decline …

Inhibition Of Growth Of Toxoplasma Gondii In Cultured Fibroblasts By Human Recombinant Gamma Interferon., E. R. Pfefferkorn, Paul M. Guyre

Dartmouth Scholarship

The growth of Toxoplasma gondii in cultured human fibroblasts was inhibited by recombinant human gamma interferon at concentrations of 8 to 16 U/ml. The interferon was titrated by observing a total inhibition of parasite plaque formation 7 days after infection. Inhibition of the growth of T. gondii in the early days after infection was measured by marked reductions in the incorporation of radioactive uracil, a precursor that can only be used by the parasites. This assay showed that when cells were pretreated with gamma interferon for 1 day and then infected, inhibition of T. gondii growth could be readily detected …

Hair As An Indicator Of Excessive Aluminum Exposure, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

To determine if excessive systemic exposure to aluminum would be reflected in increased aluminum concentration in hair, rabbits were given a series of aluminum lactate injections. Hair was collected before the aluminum lactate administration from the site of injections and twice after the injections from this site as well as from an area adjoining the injection site. Aluminum was determined by flameless atomic absorption analysis of acid-digested samples. The concentration of aluminum in the hair increased after the injections in samples taken at both times from both sites. Considerable variability in hair aluminum was found before excessive exposure, as has …

Unnecessary Suffering: Definition And Evidence, Frank Hurnik, Hugh Lehman

Attitudes Towards Animals Collection

Although it is possible to formulate stronger moral principles than "animals should not be made to suffer unnecessarily," there are significant grounds for doubting these stronger principles. But the principle that underlies the dictum regarding unnecessary suffering is generally recognized as valid, since denial of it implies that we can do whatever we want with animals, a conclusion that is usually considered unacceptable. A determination of whether any particular instance of suffering is necessary or unnecessary must be based on an analysis of both the seriousness of the purpose of the act that involves pain in animals, and its relative …

The Economics Of Farm Animal Welfare, A. J. F. Webster

Agribusiness Collection

The number of ways that one can be nice or nasty to animals are legion. This article will consider only one very specific aspect of farm animal welfare, namely, those systems of intensive animal production in which the system itself, irrespective of the quality of the stockmanship within the system, appears to restrict the normal behavior of farm animals to an unacceptable degree. The systems that were considered by the House of Commons Select Committee on Agriculure (1981) include egg production from hens in battery cages, production of veal from calves deprived of solid food and isolated in wooden crates, …

Cellular Action Of Vasopressin In Medullary Tubules Of Mice With Hereditary Nephrogenic Diabetes Insipidus, Brian A. Jackson, Richard M. Edwards, Heinz Valtin, Thomas P. Dousa

Dartmouth Scholarship

Our previous studies (1974. J. Clin. Invest.54: 753-762.) suggested that impaired metabolism of cyclic AMP (cAMP) may be involved in the renal unresponsiveness to vasopressin (VP) in mice with hereditary nephrogenic diabetes insipidus (NDI). To localize such a defect to specific segments of the nephron, we studied the activities of VP-sensitive adenylate cyclase, cAMP phosphodiesterase (cAMP-PDIE), as well as accumulation of cAMP in medullary collecting tubules (MCT) and in medullary thick ascending limbs of Henle's loop (MAL) microdissected from control mice with normal concentrating ability and from mice with hereditary NDI.

Adenylate cyclase activity stimulated by VP or by …

Reverence For Life: An Ethic For High School Biology Curricula, George K. Russell

Education Collection

Ethical and pedagogical arguments are presented against the use of animals by high school students in experiments causing pain/suffering/death of the animal. No justification is seen for such experimentation when perfectly valid alternatives, using noninvasive techniques, exist or could be developed. An important concern is the emotional and psychological growth of young people. An overall objective of high school biology curricula must be to assist students in making viable connections with living biological processes and the natural world.

Objectives Of Animal Use In Biology Courses, William V. Mayer

Education Collection

To confine discussion of educational use of animals to experimentation is to focus on only part of the animal use problem. To focus on use of animals in the classroom solely is to negate the value of field and community resource areas such as zoos, animal parks, nature trails, etc. The primary objective in dealing with living organisms is to inculcate a respect for all life. Objectives that focus on use of living animals for experimental purposes can, at best, be secondary and may in many cases be contrived. An understanding of animal life requirements and animal contributions is an …

Humaneness Supersedes Curiosity, F. Barbara Orlans

Education Collection

Ethical considerations need to be addressed with respect to educational use of animals. Society extends greater latitude in what is permissible to do to an animal in the name of science to a professional research worker than to a high school student. A balance needs to be made of the significance of the expected experimental results, on the one hand, which the ethical costs, (in terms of pain or death to the animal), on the other. A reasonable boundary can be drawn, based on ethical as well as on practical considerations, to exclude invasive procedures on vertebrate animals in high …

Fundamental Criteria For Determining The Educational Value Of Live Animal Experimentation In High School Science Fairs, David H. Neil

Education Collection

The author contends that great and very detailed attention to one minuscule facet of experimental animal biology, particularly if it requires the skilled and uniform alteration of a significant number of animals, is of no real educational value to a high school student. This type of work, the necessity for it and the full understanding of its significance to the furtherance of human understanding must be the province only of those who are intellectually prepared. The suggestion is made that projects, which develop a more complete understanding of common and profoundly important elements in life (as we know it), should …

Some Effects Of Inorganic Fluoride On Plants, Animals, And Man, Delbert A. Greenwood

Faculty Honor Lectures

~~~ in the compounds of fluorine may be traced to one or more of the following factors: ( 1) the consumption of a drinking water containing one part per million of fluorine as a soluble flouride during the period of calcification and eruption of the teeth causes a reduction in the incidence of tooth decay; however, an intake of drinking water containing more than two parts per million of fluorine causes dental fluorosis of varying degrees in man and certain animals; (2) a continuous intake of excessive amounts of fluorine as mineral supplement, in contaminated forage, or the grazing of …
