Effects Of Feeding Regimen On Performance, Behavior And Body Temperature Of Feedlot Steers, Shane Davis, Terry L. Mader, Wanda Cerkoney

Nebraska Beef Cattle Reports

One hundred forty-four predominantly Angus x Charolais steers were used to determine effects of different feeding regimens on performance, behavior and tympanic temperatures of steers under environmental heat stress. Steers were assigned to one of three treatments: 1) ad libitum fed at 0800 hr (ADLIB); 2) fed at 1600 hr with bunks slick by 0800 hr (BKMGT); and 3) fed 85% of predicted DMI at 1600 hr (LIMFD). Treatments were imposed for 23 days after which all steers were allowed ad libitum access to feed at 0800 hr. Overall performance was not affected by treatment. Altering feed time and amount …

Compensatory Growth And Slaughter Breakevens Of Yearling Cattle, D. J. Jordon, Terry J. Klopfenstein, Todd Milton, Rob Cooper

Nebraska Beef Cattle Reports

A two-year summary of growing/ finishing systems indicates that steer calves wintered at 1.5 lb/day had lower slaughter breakeven (P < .05) costs compared to animals wintered at 0.5 lb/day. Additionally, feeding wet corn gluten feed as an energy source to increase winter gains tended (P < .15) to produce slaughter breakevens which were lower than the same winter gains produced by feeding corn. Restricting animal gain over the winter (0.5-1.0 lb/day) resulted in 25-32% compensation on grass compared to controls (1.5 lb/day). Comparison of calf finishing vs. yearling growing/finishing systems showed that steers wintered with a “fast” rate of gain (1.5 lb/day) profited $28.85/head compared to losses by steers wintered with a “slow” rate of gain (0.5 lb/day; $-30.24/head) or calf finishing ($-20.87/head).

Forage Intake And Nutrient Balance Of Heifers Grazing Sandhills Winter Range, Trey Patterson, Don C. Adams, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Two experiments with pregnant heifers grazing winter range investigated effects of supplementation to meet metabolizable protein versus CP requirements. Supplements were fed from October to February, and hay was fed in January and February of the second experiment. Supplementation to meet metabolizable protein requirements decreased weight loss in one experiment. Winter hay feeding reduced weight loss and body condition loss compared to no hay feeding. Forage intake declined from 2.1% of body weight in November to 1.3% in February. Metabolizable protein was deficient when animals were supplemented to meet CP requirements. Supplementation to meet metabolizable protein requirements may improve performance …

Performance And Economics Of Winter Supplementing Pregnant Heifers Based On The Metabolizable Protein System, Trey Patterson, Don C. Adams, Terry J. Klopfenstein, Richard T. Clark, Burke Teichert

Nebraska Beef Cattle Reports

In 1997-1998 and 1998-99, pregnant, March-calving heifers (2,375 head) at two locations of a ranch in Nebraska were used to evaluate the production and economic responses of winter supplementation (September to February) to meet metabolizable protein or CP requirements. Net present value was used to determine the economic benefits of supplement treatments. In 1997-98, metabolizable protein heifers had higher pregnancy rates and expected profitability than CP heifers at one of two locations. In 1998-99, metabolizable protein heifers had higher pregnancy rates and expected profitability at both locations.

A Study Of The Effect Of The Integration Of Children's Literature Into The Science Curriculum On Student Understanding Of Scientific Concepts, Emily R. Morgan

Graduate Theses and Dissertations

The effect of integrating children's literature into the science curriculum on student understanding of science concepts was investigated. The study involved 354 third-grade students from 14 classrooms. Students in the traditional textbook group read and discussed the textbook on a certain science topic, performed a hands-on science activity or experiment on the topic, and were tested for understanding of that topic. Students in the literature group followed the same procedure but the textbook was substituted with science trade books. Student understanding was determined by collecting scores on district Performance Objective Assessments. Results were analyzed with a multivariate analysis using the …

Avian Use Of Various Bait Mixtures Offered In Harvested Cornfields During Spring Migration In South Dakota, George M. Linz, H. Jeffrey Homan, Ryan L. Wimberly

United States Department of Agriculture Wildlife Services: Staff Publications

The avicide, DRC-1339, is used to cull populations of spring-migrating blackbirds in eastern South Dakota to reduce damage to ripening sunflower in late summer. We investigated non-target bird hazards associated with using various grain mixtures to attract blackbirds (Icteridae), especially red-winged blackbirds (Agelaius phoeniceus), to avicide-treated bait broadcast in harvested cornfields. During spring 1997 and 1998, we recorded the species and numbers of birds attracted to 0.2-ha plots baited with cracked corn and brown rice, fine-chipped sunflower meats and brown rice (1997 only), and unsupplemented brown rice. Unbaited plots were used as reference sites. In 1997 and 1998, …

Making A Difference For Children Affected By Aids: Baseline Findings From Operations Research In Uganda, Laelia Gilborn, Rebecca Nyonyintono, Robert Kabumbuli, Gabriel Jagwe-Wadda

HIV and AIDS

Many organizations and programs have begun to provide services and support to AIDS-orphaned children in East and southern Africa. Typical program components include the provision of school fees and supplies, supplementary feeding, home-visiting programs in which community members visit and assist affected children, and vocational training. However, few of these programs have been formally evaluated for impact. This paper reports on baseline findings from a study of two programs for AIDS-affected children and their families implemented by PLAN International in the Luwero and Tororo districts of Uganda. One program, referred to as orphan support, provides educational, health, and nutritional assistance …

Habitat Ecology Of The Native Subtidal Snail, Lacuna Vincta, In The Gulf Of Maine And The Impact Of Two Introduced Species, Suchana Chavanich

Doctoral Dissertations

Lacuna vincta (Montagu) is a small native herbivorous gastropod that feeds and lives on algae within the rocky subtidal zone of New England. In this study, a combination of field samplings and laboratory experiments were conducted in order to examine the seasonal abundance, feeding preference, and growth of snails on nine different algal species. The results showed that there were differences in the seasonal abundance patterns of L. vincta populations on different algal species. However, the snail populations in all size classes were found year round on Laminaria saccharina (L.) Lamour. Feeding preference experiments showed that L. vincta preferred Antithamnionella …

Regulation Of Mammalian Photoreceptor Phosphodiesterase (Pde) By Its Noncatalytic Gaf Domains And Its Two Small Subunits, Gamma And Delta, Hongmei Mou

Doctoral Dissertations

cGMP phosphodiesterase (PDE) is the central effector of visual transduction in retinal rod photoreceptors. The overall goal of this work was to investigate the possible regulatory mechanisms of PDE in mammalian rod photoreceptors by its noncatalytic cGMP binding sites on the PDE catalytic dimer (Palphabeta), and by the interactions between the inhibitory Pgamma subunit and Palphabeta in their phosphorylated and non-phosphorylated states.

First, the binding of cGMP to the noncatalytic sites on membrane-associated PDE (PDE-M) and soluble PDE (PDE-S) was characterized. We found that PDE-M holoenzyme contains 2 non-identical high-affinity cGMP binding sites; one of the cGMP binding sites is …

Setting Limits: Medical Technology And The Law, George P. Smith Ii

Scholarly Articles

The allocation and rationing of health care resources is, no doubt, one of the most pressing issues confronting contemporary society. These issues considered from a micro and a macro level of economic analysis are linked inextricably to utilitarianism which, in turn, relies upon a cost-benefit analysis which balances reasonable individual needs against the availability of medical resources within the larger community. From an ethical viewpoint, the cost-benefit approach to the distribution of health care resources is impractical because it seeks to reduce (or convert) all health benefits to dollar amounts, thereby seeking very awkwardly to convert quality of life benefits …

The Effects Of Line Dancing On Balance And Coordination In The Elderly, Sara Welder

Physical Therapy Scholarly Projects

The purpose of this study was to determine if a six-week line dancing program has a significant effect on balance and coordination in a geriatric population. If proven effective, line dancing can be added to the options available to physical therapists for balance and coordination training.

A total of 12 volunteer subjects participated in this study. They were separated into two groups, a control group (n = 6, 4 females and 2 males), and a dance group (n = 6, all female) according to participant's preference. Subjects were in good health, were high functioning , and were found to be …

Bone Cutting, Placement, And Cannibalism? Middle Preceramic Mortuary Patterns Of Nanchoc, Northern Peru, Jack Rossen, Tom D. Dillehay

Anthropology Faculty Publications

Mortuary practices of the Middle Preceramic period (ca. 8500-4000 B.P.) are discussed for the Nanchoc region of the upper Zaña Valley, northern Peru. Careful breaking, cutting, and placement of human bones from adult males during the Las Pircas Phase (8500-6000 B.P. ) gave way to more haphazard breakage and discard during the subsequent Tierra Blanca Phase (6000-5000 B.P.). The evidence of cannibalism is considered. Bone breakage, cutting, and possibly cannibalism is believed to have been part of a broader process of ritualization that mitigated the spiritual danger of the transition from hunting-gathering to horticulture.

High School Students' Food Choices: A Nutrient Analysis Of Students' Canteen Purchases At Four High Schools, Jenny Kora

Theses : Honours

Links exist between poor eating habits established during childhood and adolescence and the development of dental decay, obesity and anaemia early in life (Ruxton, Kirk, Belton & Holmes, 1993; Douglas, 1999), as well as a number of diseases of affluence, including cardiovascular disease, diabetes and some cancers later in life (Baranowski et al., 1993; Birch, 1993; National Health and Medical Research Council, 1995; Antine, 1997; Harris et al., 1997; Douglas, 1998; Melnik, Rhoades, Wales, Cowel & Wolfe, 1998; Cholin, 1999; Huon, Wardle & Szabo, 1999).

Rebuilding The Wall, Bill Davis

Animal Law Review

The debate about whether nonhuman animals deserve legal rights encompasses an ever broadening range of theories and strategies. Most thinkers pushing for nonhuman animal rights reject speciesism, which they view as an often tacit foundation for their adversaries' arguments. Yet almost every current contributor to the debate-whether they favor or disfavor the extension of rights beyond the human sphere-engages in some form of intelligenceism by focusing disproportionate attention on humanlike animals. This essay submits that nonhuman animal advocates must recognize this pervasive intelligenceist bias and be wary of the detrimental effects its substitution for speciesism could have on their long-term …

Cost-Benefit Analysis And Relative Position, Cass R. Sunstein, Robert H. Frank

Articles

Current estimates of regulatory benefits are too low and possibly far too low. This is because the standard economic approach to measuring costs and benefits, which attempts to estimate people's willingness to pay for various regulatory benefits, ignores a central point about valuation, thus producing numbers that systematically understate those benefits. Conventional estimates tell us the amount of income an individual, acting in isolation, would be willing to sacrifice in return for, say, an increase in safety on the job. But while these estimates are based on the implicit assumption that economic well-being depends only on absolute income, considerable evidence …

The Arithmetic Of Arsenic, Cass R. Sunstein

Articles

What does cost-benefit analysis mean, or do, in actual practice? When agencies engage in cost-benefit balancing, what are the interactions among law, science, and economics? This Article attempts to answer that question by exploring, in some detail, the controversy over the EPA's proposed regulation of arsenic in drinking water The largest finding is that often science can produce only "benefit ranges, " and wide ones at that. With reasonable assumptions based on the scientific data before the EPA at the time it made its initial decision, the proposed arsenic regulation can be projected to save as few as 0 lives …

Zinc Fertilizer Rates And Mehlich Iii Soil Test Levels For Corn, Lloyd W. Murdock, Paula L. Howe

Agronomy Notes

Zinc (Zn) is the micronutrient most often deficient for corn in Kentucky. This problem occurs every year but is more commonly seen in years with a cool, wet spring. Although the environment, soil type and past erosion each have an effect, the most important factors controlling plant available Zn are the soil pH, extractable soil phosphorus (P) and extractable soil Zn. While the amount of Zn in the plant increases as the available soil Zn increases, increasing levels of soil P and pH are strongly associated with reduced levels of Zn in the plant.

Reproductive Health

With the reform movement in Indonesia, the FRONTIERS project recognized the new opportunities for influencing public debate and informing public opinion on reproductive health issues and undertook a project for disseminating the results of contemporary research on reproductive health. The project had three main objectives: 1) to increase print media coverage of critical reproductive health issues by enhancing journalists’ role as responsible communication agents; 2) to contribute to public debate on emerging reproductive health issues in order to influence policy development and guide program management; and 3) to increase public awareness of key health issues, with a particular focus on …

Power In Sexual Relationships: An Opening Dialogue Among Reproductive Health Professionals, Population Council, Interagency Gender Working Group (Igwg)

Reproductive Health

The discussions summarized in this report indicate that gender-based power inequalities hinder communication between partners, limit the ability of individuals and couples to talk about or achieve desired child spacing and family-size goals, limit effective use of reproductive health services, undercut men’s and women’s attainment of sexual health and pleasure, and increase substantially their vulnerabiliy to HIV/AIDS and other sexually transmitted infections. This report summarizes the proceedings of a meeting, co-sponsored by the Population Council and USAID’s Men and Reproductive Health Subcommittee, that responded to an increasing groundswell of interest in opening a dialogue on power in sexual relationships.

Nitric Oxide And Cnidarian-Dinoflagellate Symbioses: Pieces Of A Puzzle, Henry G. Trapido-Rosenthal, Katherine H. Sharp

Arts & Sciences Faculty Publications

The presence of nitric oxide synthase (NOS) activity is demonstrated in the tropical marine cnidarian Aiptasia pallida and in its symbiotic dinoflagellate algae, Symbiodinium bermudense. Enzyme activity was assayed by measuring the conversion of arginine to citrulline. Biochemical characterization of NOS from Aiptasia was characterized with respect to cellular localization, substrate and cofactor requirements, inhibitors, and kinetics. In response to acute temperature shock, anemones retracted their tentacles. Animals subjected to such stress had lower NOS activities than did controls. Treatment with NOS inhibitors caused tentacular retraction, while treatment with the NOS substrate L-arginine inhibited this response to stress, as did …

A Simple Performance-Based Index For Assessing Multiple Agroecosystem Functions, Mark A. Liebig, Gary E. Varvel, John W. Doran

Department of Agronomy and Horticulture: Faculty Publications

Evaluating the impact agricultural practices have on agroecosystem functions is essential to determine the sustainability of management systems. This paper presents an approach to determine the relative sustainability of agricultural practices. A simple ranking procedure using a relative scoring method is proposed to discriminate among treatments based on the status of crop and soil parameters within different agroecosystem functions. Summing scores across agroecosystem functions allows for the identification of agricultural practices that are performing optimally based on functions included in the procedure. An example, using data from a long-term cropping systems experiment in the western Corn Belt, found the indexing …
