Calculation of Demographic Parameters in Tropical Livestock Herds


Book Description

Having indicators to assess the effect of zootechnical, sanitary, economic or political intervention or the impact of environmental risks makes it possible to draw up strategies for improving domestic animal populations. This handbook is a compilation of the main concepts relating to the definition and calculation of demographic rates for largely non-intensive tropical animal farms. It is intended to be educational, and should help students, technicians, engineers, researchers and development staff to understand the definitions and formulas encountered in the literature more clearly and make them more self-sufficient in terms of analyses.







Measuring the Role of Livestock in the Household Economy


Book Description

This guidebook presents a module template for effectively including livestock in multitopic and agricultural household surveys in low- and middle- income countries. It is a practical tool for survey practitioners to collect data on the role of livestock in the household economy and its contribution to livelihoods. The data will assist in generating statistics on key features of the smallholder livestock sector - from herd size and composition to husbandry and production practices, from meat, milk and egg production to livestock income. These statistics represent the backbone for effective livestock-sector policies and investments.




Goat Production and Supply Chain Management in the Tropics


Book Description

This book is a practical manual for goat production systems covering: breeding and selection, feeding based on available crops and resources, and targeted preventative health care for increased productivity and income. It outlines best practice and strategies for setting up a farm, overcoming challenges, increasing milk and meat quality, obtaining sustainability, reducing environmental pollution, optimising climatic conditions and tapping into local know-how. In addition, the book details developing region-specific data for effective decision making and better management, as well as how to run a developmental project to empower stake holders for higher production, support innovation, and analyse the supply chain for better product quality and marketing.







The Genetics of Cattle, 2nd Edition


Book Description

Since the time of domestication more than 10,000 years ago, cattle have played an increasingly crucial role in the development of human civilizations. Progress has been quite remarkable since the turn of the century; the sequencing of the bovine genome in 2009 launched new avenues for furthering our understanding of theoretical and practical aspects of cattle genetics. Covering a vast array of questions, this book reviews major topics from molecular and developmental genetics, disease resistance and immunogenetics to genetic improvement of dairy and beef breeds, addressing all current problems in the field. This second edition includes a new team of authors and completely new chapters on the genetics of fat production, nutrition, feed intake and efficiency, growth and body composition. Fully updated throughout, it provides a valuable resource on cattle genetics for researchers, breeders, veterinarians and postgraduate students.




Prospects for Livestock-Based Livelihoods in Africa's Drylands


Book Description

Prospects for Livestock-Based Livelihoods in Africa's Drylands examines the challenges and opportunities facing the livestock sector and the people who depend on livestock in the dryland regions of Sub-Saharan Africa. It presents a novel way of thinking about pastoral development, grounded in a conceptual framework that focuses on the multiple shocks that drylands livestock keepers face and how those shocks can be addressed, drawing on a state-of-the-art literature review carried out by scientists of leading research institutes and development organizations, and integrating the results of an innovative approach to modeling development options for the drylands livestock sector. Looking to the future, the picture is mixed. On the positive side, demand for red meat is expected to strengthen in domestic and regional markets, suggesting that livestock keepers will have good market opportunities. On the negative side, a large majority of livestock keepers are classifi ed as poor, and the natural (feed) resource base is likely to be suffi cient to enable improved meat and milk production for the growing human population. Prospects for the livestock sector through 2030 vary by aridity zone. In arid and semi-arid zones, a reasonable goal for 2030 is to have land use, training, and microfi nance systems established that promote an appropriate balance between human and livestock carrying capacities, featuring mainly grassland/pastoral systems that reliably and sustainably satisfy the minimum income needs of herder households, produce at least a signifi cant part of the demand in local markets for animal source food, and provide environmental services for which livestock keepers receive compensation. The goal includes signifi cant employment generation outside the sector. In the higher rainfall zones of the semi-arid areas, and in the subhumid zones, a reasonable goal for 2030 is to have intensifi ed production systems established, featuring mainly mixed livestock/arable farming or agro-pastoral systems that are closely linked to nearby grassland/pastoral systems and that consistently generate marketable surpluses of differentiated red meat and livestock products that can compete not only in the expanding domestic market but also in selected regional markets.

Focusing Livestock Systems Research


Book Description

This book is based on the papers and discussions of the workshop Diagnosis of livestock systems: description, analysis and research planning. In this workshop, organized in Sikasso, Mali, 1992, agricultural researchers discussed how to achieve basic understanding and to outline initial livestock research priorities
