Download or read book Breeding Strategies for Genetic Improvement of Dairy Cattle written by Tobias Okeno Otieno and published by LAP Lambert Academic Publishing. This book was released on 2012-04 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dairy production has been recognised as a strategy to wealth creation and overcoming the worsening problems of poverty, unemployment, malnutrition, and hunger among the resource-poor households in developing countries. Although the demand for dairy products is ever increasing, improving the production efficiency of dairy cattle to satisfy the demand is the biggest challenge faced by developing countries. In Kenya for instance, different breeding strategies have been employed to improve the productivity of dairy cattle. However, the choice of these strategies has often been done without due regard to their genetic and economic efficiency. This study therefore examined the genetic and economic efficiency of breeding strategies involving utilization of local and imported genetic materials to improve dairy cattle productivity in Kenya using a deterministic approach. Such evaluations are inevitable when an efficient and sustainable improvement breeding programme is to be developed. This book is therefore, developed to provide information on genetic and economic merits of different breeding strategies in relation to their adoption for genetic improvement of dairy cattle in Kenya.

Download or read book The State of the World s Animal Genetic Resources for Food and Agriculture written by Barbara Rischkowsky and published by Food & Agriculture Org.. This book was released on 2007 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable management of the world's livestock genetic diversity is of vital importance to agriculture, food production, rural development and the environment. "The State of the World's Animal Genetic Resources for Food and Agriculture" is the first global assessment of these resources. Drawing on 169 Country Reports, contributions from a number of international organizations and 12 specially commissioned thematic studies, it presents an analysis of the state of agricultural biodiversity in the livestock sector - origins and development, uses and values, distribution and exchange, risk status and threats - and of capacity to manage these resources - institutions, policies and legal frameworks, structured breeding activities and conservation programmes. Needs and challenges are assessed in the context of the forces driving change in livestock production systems. Tools and methods to enhance the use and development of animal genetic resources are explored in sections on the state of the art in characterization, genetic improvement, economic evaluation and conservation. The main findings of the report are summarized in "The State of the World's Animal Genetic Resources for Food and Agriculture - in brief," of which the Arabic, Chinese, English, French, Russian and Spanish versions can be found on the attached CD-ROM and are also available separately in printed form. As well providing a technical reference document, the country-based preparation of "The State of the World" has led to a process of policy development and a "Global Plan of Action for Animal Genetic Resources," which once adopted, will provide an agenda for action by the international community. Published also in French.

Book excerpt: This "in brief" version, intended for use by decision-makers and the wider public, presents a summary of the key findings of the main report (see above). Part 1 outlines the state of agricultural biodiversity in the livestock sector. Part 2 considers the livestock production systems of which animal genetic resources form a part. Part 3 - largely based on the 148 Country reports - is an assessment of institutional and human capacity in the field of animal genetic resources management. Part 4 presents the state of the art in terms of the methods available for the management of animal genetic resources. As well as providing a technical reference document, the country-based preparation of The State of the World" has led to a process of policy development and a Global Plan of Action for Animal Genetic Resources, which once adopted, will provide an agenda for action by the international community.
Download or read book THE SECOND REPORT ON THE STATE OF THE WORLD s ANIMAL GENETIC RESOURCES FOR FOOD AND AGRICULTURE written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-06-06 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal genetic resource diversity underpins the supply livestock products and services across a wide range of production environments. It promotes resilience and serves as a basis for adapting livestock management to changing conditions. It is vital to livelihoods of many of the world’s poor people. It can contribute to the delivery of ecosystem services such as landscape management and the maintenance of wildlife habitats. However, it is often undervalued, underused and under threat. This report updates the global assessment provided in the first report on The State of the World’s Animal Genetic Resources for Food and Agriculture, published in 2007. It focuses particularly on changes that have occurred during the period since the first report was published. It serves as a basis for a review, and potential update, of the Global Plan of Action for Animal Genetic Resources, which since 2007 has provided an agreed international framework for the management of livestock biodiversity. Drawing on 129 country reports, it presents an analysis of the state of livestock diversity, the influence of livestock-sector trends on the management of animal genetic resources, the state of capacity to manage animal genetic resources, including legal and policy frameworks, and the state of the art in tools and methods for characterization, valuation, use, development and conservation.
Download or read book Tackling Climate Change Through Livestock written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2013 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.
Download or read book International Genetic and Genomic Evaluations of Beef Cattle written by and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In cattle, advancements in reproductive technologies such as artificial insemination allowed breeders to access the genetic material of superior bulls from foreign countries. However, animals’ estimated breeding values (EBV) computed from different national evaluations are not directly comparable across countries due to differences in scales and genetic bases, trait and model definitions, and the possible presence of genotype-by-environment interactions. International evaluations account for such differences by jointly analysing all national data and modelling the same trait recorded in different countries as different correlated traits. The resulting international EBV (EBVINT) facilitate the comparison of domestic and foreign sires and worldwide trading of their genetic material. This thesis aimed to improve and further develop methodologies for international beef cattle evaluations (Interbeef) by addressing various challenges, mainly related to: i) the estimation of across-country genetic correlations (rg) and their impact on the EBVINT; ii) the inclusion of national genomic information; and iii) the development of an official procedure for participating countries to integrate the distributed EBVINT back into their national evaluations. First, I showed that both large and small participating countries benefit from current Interbeef pedigree-based evaluations. Second, I showed the feasibility of estimating across-country rg using a multi-trait approach that simultaneously fits data from all countries and proposed data sub-setting strategies to improve computational time. Third, I showed that the current practice of assuming across-country direct-maternal rg to be 0 has limited impact on the EBVINT of animals of interest such as publishable sires, i.e., sires that meet Interbeef publications rules. On the other hand, assuming zero within-country direct-maternal rg impacts the EBVINT of such animals. Fourth, I developed international genomic evaluations for beef cattle using a single-step SNPBLUP approach (ssSNPBLUP). International ssSNPBLUP evaluations lead to higher accuracies compared to both current international pedigree evaluations and either national pedigree or genomic evaluations, while keeping similar or slightly reduced level and dispersion bias. Finally, I developed a generalized procedure to integrate pedigree-based or single-step EBVINT of publishable sires into national evaluations. The procedure can be easily implemented with current software. Compared to national evaluations without integration, the integration reduces level bias, gives similar dispersion, and increases accuracies of publishable sires’ EBVINT. Overall, this thesis contributes to the development of international evaluations of beef cattle.
