Download or read book Genomically Enhanced Predictions of Dairy Cattle Fertility written by Emily Marie Sitko and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research presented in this thesis aimed at improving the efficiency of dairy farms through the development of targeted reproductive management strategies (TRM) based on genomically enhanced predictions of fertility, and the elucidation of associations between genetic merit for fertility and biological outcomes that affect dairy cow reproductive performance.Chapter II and III present the results of an experiment designed to compare the association between genetic merit for fertility and reproductive and profitability outcomes of cows submitted for artificial insemination (AI) with management programs that prioritized AI at detected estrus (AIE) or timed AI (TAI). Another objective was to determine if cows with different genetic potential for fertility would present a distinct response to the strategies compared. The study presented in Chapter IV and V characterized associations between genetic merit for fertility and biological parameters known to alter reproductive performance of cows. Results presented in Chapter II and III indicated that primiparous Holstein cows of superior genetic merit for fertility had better reproductive performance than cows of inferior genetic merit for fertility regardless of the type of reproductive management used. In addition, the effect of TRM based on genetic merit for fertility on reproductive performance depended on the outcome or sets of outcomes of interest evaluated. For example, cows of superior and intermediate genetic merit for fertility had greater P/AI when managed with the predominant TAI program but reduced days to pregnancy when managed with the program that prioritized AIE. Cows of inferior fertility also had greater first service P/AI with the program that prioritized TAI but had similar days to pregnancy with both management strategies. From an economic standpoint, cows of inferior fertility had greater cash flow than cows of superior fertility. For cows in specific fertility groups, the effects of the reproductive management strategies compared generated differences in cash flow of potential value for commercial dairy farms. The study presented in Chapter IV and V demonstrated a potential association of genomic merit for fertility with physiological and endocrine parameters known to affect reproductive performance of dairy cows. Particularly, cows of inferior genetic merit for fertility had poorer uterine health, decreased response to synchronization of estrus and ovulation, and were more likely to present altered ovarian and hormonal phenotypes that led to more frequent expression of atypical estrous cycles as compared with cows of superior genetic merit for fertility. Overall, we observed that genetically enhanced predictions of fertility might be a suitable tool for decision making in TRM. Additionally, the value of TRM programs for cows of different genetic merit for fertility might be on improving aspects of herd management such as simplifying program implementation or reducing reliance on hormonal interventions while maintaining acceptable levels of reproductive performance. An improved understanding of biological differences associated with genetic variation, such as our observations in Chapter IV and V, may be beneficial for the development of novel TRM and technologies to improve the reproductive efficiency of dairy cattle. This novel information could also support the development of new traits for selection of fertility.

This book was released on 2013 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current analysis was conducted to evaluate the potential of nutritional, manure and animal husbandry practices for mitigating methane (CH4) and nitrous oxide (N2O) - i.e. non-carbon dioxide (CO2) - GHG emissions from livestock production. These practices were categorized into enteric CH4, manure management and animal husbandry mitigation practices. Emphasis was placed on enteric CH4 mitigation practices for ruminant animals (only in vivo studies were considered) and manure mitigation practices for both ruminant and monogastric species. Over 900 references were reviewed; simulation and life cycle assessment analyses were generally excluded

Download or read book Sterile Insect Technique written by Victor A. Dyck and published by CRC Press. This book was released on 2021-01-06 with total page 1493 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sterile insect technique (SIT) is an environment-friendly method of pest control that integrates well into area-wide integrated pest management (AW-IPM) programmes. This book takes a generic, thematic, comprehensive, and global approach in describing the principles and practice of the SIT. The strengths and weaknesses, and successes and failures, of the SIT are evaluated openly and fairly from a scientific perspective. The SIT is applicable to some major pests of plant-, animal-, and human-health importance, and criteria are provided to guide in the selection of pests appropriate for the SIT. In the second edition, all aspects of the SIT have been updated and the content considerably expanded. A great variety of subjects is covered, from the history of the SIT to improved prospects for its future application. The major chapters discuss the principles and technical components of applying sterile insects. The four main strategic options in using the SIT — suppression, containment, prevention, and eradication — with examples of each option are described in detail. Other chapters deal with supportive technologies, economic, environmental, and management considerations, and the socio-economic impact of AW-IPM programmes that integrate the SIT. In addition, this second edition includes six new chapters covering the latest developments in the technology: managing pathogens in insect mass-rearing, using symbionts and modern molecular technologies in support of the SIT, applying post-factory nutritional, hormonal, and semiochemical treatments, applying the SIT to eradicate outbreaks of invasive pests, and using the SIT against mosquito vectors of disease. This book will be useful reading for students in animal-, human-, and plant-health courses. The in-depth reviews of all aspects of the SIT and its integration into AW-IPM programmes, complete with extensive lists of scientific references, will be of great value to researchers, teachers, animal-, human-, and plant-health practitioners, and policy makers.

Download or read book Environmental Consequences of the Chernobyl Accident and Their Remediation written by International Atomic Energy Agency and published by IAEA. This book was released on 2006 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explosion on 26 April 1986 at the Chernobyl nuclear power plant and the consequent reactor fire resulted in an unprecedented release of radioactive material from a nuclear reactor and adverse consequences for the public and the environment. Although the accident occurred nearly two decades ago, controversy still surrounds the real impact of the disaster. Therefore the IAEA, in cooperation with other UN bodies, the World Bank, as well as the competent authorities of Belarus, the Russian Federation and Ukraine, established the Chernobyl Forum in 2003. The mission of the Forum was to generate 'authoritative consensual statements' on the environmental consequences and health effects attributable to radiation exposure arising from the accident as well as to provide advice on environmental remediation and special health care programmes, and to suggest areas in which further research is required. This report presents the findings and recommendations of the Chernobyl Forum concerning the environmental effects of the Chernobyl accident.

Available in PDF, EPUB and Kindle. Book excerpt: Polonium-210 is an alpha emitting radionuclide with no radioactive progeny and produces only very-low-intensity gamma rays at very low abundance. This means doses largely arise from internal exposure. In addition to the relatively high ingestion does coefficient of 210Po, radionuclide transfer in the environment results in high activity concentrations in certain foods. This publication focuses on radionuclide transfers in terrestrial, freshwater and marine environments, and provides information on key transfer processes, concepts and models--back cover.

This book was released on 2017-04-25 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report assesses the levels and effects of exposure to ionizing radiation. Scientific findings underpin radiation risk evaluation and international protection standards. This report comprises a report with two underpinning scientific annexes. The first annex recapitulates and clarifies the philosophy of science as well as the scientific knowledge for attributing observed health effects in individuals and populations to radiation exposure, and distinguishes between that and inferring risk to individuals and populations from an exposure. The second annex reviews the latest thinking and approaches to quantifying the uncertainties in assessments of risk from radiation exposure, and illustrates these approaches with application to examples that are highly pertinent to radiation protection.

Download or read book Agricultural Implications of the Fukushima Nuclear Accident III written by Tomoko M. Nakanishi and published by Springer. This book was released on 2019-01-30 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents the findings from on-site research into radioactive cesium contamination in various agricultural systems affected by the Fukushima Daiichi Nuclear Power Plant accident in March 2011. This third volume in the series reports on studies undertaken at contaminated sites such as farmland, forests, and marine and freshwater environments, with a particular focus on livestock, wild plants and mushrooms, crops, and marine products in those environments. It also provides additional data collected in the subsequent years to show how the radioactivity levels in agricultural products and their growing environments have changed with time and the route by which radioactive materials entered agricultural products as well as their movement between different components (e.g., soil, water, and trees) within an environmental system (e.g., forests). The book covers various topics, including radioactivity testing of food products; decontamination trials for rice and livestock production; the state of contamination in, trees, mushrooms, and timber; the dynamics of radioactivity distribution in paddy fields and upland forests; damage incurred by the forestry and fishery industries; and the change in consumers’ attitudes. Chapter 19 introduces a real-time radioisotope imaging system, a pioneering technique to visualize the movement of cesium in soil and in plants. This is the only book to provide systematic data on the actual change of radioactivity, and as such is of great value to all researchers who wish to understand the effect of radioactive fallout on agriculture. In addition, it helps the general public to better understand the issues of radio-contamination in the environment. The project is ongoing; the research groups from the Graduate School of Agricultural and Life Sciences of The University of Tokyo continue their work in the field to further evaluate the long-term effects of the Fukushima accident.

Download or read book Area wide Integrated Pest Management written by Jorge Hendrichs and published by CRC Press. This book was released on 2021-02-01 with total page 1028 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, including non-target species, air, water and soil. The extensive reliance on insecticide use reduces biodiversity, contributes to pollinator decline, destroys habitat, and threatens endangered species. This book offers a more effective application of the Integrated Pest Management (IPM) approach, on an area-wide (AW) or population-wide (AW-IPM) basis, which aims at the management of the total population of a pest, involving a coordinated effort over often larger areas. For major livestock pests, vectors of human diseases and pests of high-value crops with low pest tolerance, there are compelling economic reasons for participating in AW-IPM. This new textbook attempts to address various fundamental components of AW-IPM, e.g. the importance of relevant problem-solving research, the need for planning and essential baseline data collection, the significance of integrating adequate tools for appropriate control strategies, and the value of pilot trials, etc. With chapters authored by 184 experts from more than 31 countries, the book includes many technical advances in the areas of genetics, molecular biology, microbiology, resistance management, and social sciences that facilitate the planning and implementing of area-wide strategies. The book is essential reading for the academic and applied research community as well as national and regional government plant and human/animal health authorities with responsibility for protecting plant and human/animal health.
