This book was released on 1983 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study are to assess the role of small ruminants (sheep and goats) in the food production systems of developing countries, examine their advantages and disadvantages, analyze the constraints limiting their further contribution to the welfare of small farm/low income rural producers, prescribe measures for overcoming these constraints, and make recommendations related to potential donor involvement in support of the development of sheep and goat production. Small ruminants are viewed as an integral, but not dominant component of complex agricultural systems. Particular emphasis is placed on sheep and goats in mixed herds grazing dry rangelands and in small mixed farm systems in medium to high rainfall areas. An analysis of major constraints -- ecological, biological, policy, and socio-economic -- leads to recommendations on the need for a balanced production system approach for research, training and development programs, and for a combination of support activities such as herd health programs, and formulation of favorable credit, marketing and pricing policies for small ruminants and their products.

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.

Download or read book Animal farming and environmental interactions in the Mediterranean region written by Isabel Casasús and published by Springer Science & Business Media. This book was released on 2012-03-26 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Livestock production systems are the result of an interaction between domestic animals and the environment, modulated by man, that dates back to Neolithic times. As a consequence of this interaction among the wide diversity of animal resources, natural habitats and population needs, very different farming systems have developed across the Mediterranean Basin. Understanding the mechanisms and effects of these relationships is key to design the farming systems best adapted to each condition, guaranteeing an adequate balance between target animal production and environmental outcomes provided by these systems. This is indeed a multidimensional topic, influenced by animal genetics, feeding resources, flock management, and economic and social aspects inside and outside the household. Therefore, this book focuses on the basis of the animal-environment interactions and the impact of human activities on the type and magnitude of these interactions. In this context, the issue of sustainability of livestock production is evaluated considering economic, social and environmental aspects. This book contributes to upgrade the state of the art in Mediterranean conditions, providing indicators and procedures of application across a wide range of systems, and hence of interest for researchers, students and professionals concerned with livestock production and the environment.

Download or read book Suitability of different Awassi lines for efficient sheep production of Bedouins in the Negev in Israel written by Anna Al Baqain and published by Cuvillier Verlag. This book was released on 2012-07-19 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary In Israel, more than half of the national sheep flock is kept by Bedouin in the Negev desert. Extensive production systems co-exist besides semi-intensive systems with varying economic success. There is a constant regional demand for sheep meat, but the local supply is not able to cover it. The wide gap between the performance potential of the commonly used and environmentally adapted local Awassi and improved sheep breeds suggests an increase in economic efficiency by intensification of breeding. The choice of a suitable breed for a specific system is seen as key factor for the farm success and requires the knowledge of the animals’ adaptation. Information on the performance of Bedouin sheep flocks under the given harsh production conditions are, however, missing. The purpose of the study was thus a characterization of current production systems, the assessment of the aggregated performance of the different Awassi lines kept in those systems and the impact of socio-economic and production factors on the efficiency of Bedouin sheep production. Also breeding objectives of Bedouin sheep farmers were investigated. The role of new breeding technologies in the ongoing process of intensification of sheep farming systems was analyzed and discussed. Data collection was step-wise with repeated field surveys from January 2007 till March 2009, lasting 6 months altogether. In a first diagnostic survey 30 Bedouin households in the Negev desert, located in two different climatic zones, arid and semi-arid, and keeping a minimum flock size of 50 animals, were visited. Households were grouped into 4 tribe groups according to location and ethnical background. In a second step, 21 households of the previous sample were visited again and grouped according to the breed composition of their flocks and by their use of hormonal synchronization and/or artificial insemination. Semi-structured interviews and participative observation yielded information about the socio-economic situation of the household, function of flocks, the livestock husbandry, sheep management and production. Sheep market surveys, key person interviews and secondary data were used for verification of data. Detailed information on sheep was obtained through on-farm performance recording run in 16 sheep farms, including a total of 2420 breeding ewes. Sheep of different Improved Awassi lines were present in those experimental flocks, including the Afec Awassi, carrying the Booroola gene (BB/B+), which has a major impact on prolificacy, and the Assaf breed. In a last step, 56 sheep farmers from different parts of the Negev were asked about their selection criteria for replacement. Trait preferences were derived by a consecutive ranking technique. The data analysis incorporated descriptive statistics, general linear models and non-parametric tests performed with SAS 9.1 and SAS 9.2 software. The diagnostic survey revealed that functions of sheep flocks differed significantly between tribes: in the semi-arid area with a main focus on generating income, and in tribes of the arid zone with a higher importance of subsistence related and social purposes. The primary purpose was meat production. The dual purpose of meat and milk was still found in 57% of the farms, yet only 13% of the farms were selling milk products. The missing market access was the main reason for a strong decline in the use of milk, wool and manure during the last decade. Lamb meat, providing the main output of all farms, ranged from 13 to 58 kg of marketable live weight per ewe and year (LME). Classified according to their LME, 30% of the investigated farms followed an extensive, 47% a semi-extensive and 23% a semi-intensive management. Significant differences in meat output were found for the factors tribe group, breed composition of flocks and selling age of lambs. The gross margin per ewe and year varied between -27 € and 54 € and the net benefit per flock and year (NB) between -7,020 € and 20,993 €. Both economic parameters were positively related to the meat output. Negative NB’s were realized by 43% of the farms, belonging foremost to traditional Bedouin tribes, oriented towards subsistence and living in remote areas. Only 27% of economically successful farms generated an income comparable to that of a part-time off-farm job. These farmers regularly used veterinary services to introduce improved breeds and modern breeding technology. Their good market access facilitated a strong market-oriented production, integrating lamb fattening, which had the highest impact on the production success. During the two years of research a severe drought occurred in the study region, causing a decline in LME, due to lower lambing rates and higher mortalities. To adapt to changing conditions, farms keeping the pure local Awassi breed reduced their flock sizes stronger than farms keeping also crossbreds. Consequently, the LME and the NB decreased stronger in flocks of pure local Awassi, compared to flocks with crossbreds. The decline in the NB was 14 times lower in flocks with use of hormonal synchronization and/or artificial insemination than in flocks with the local breed kept under traditional management. The lowest decline in the NB and the benefit cost ratio (BCR) were found in flocks with more than 50% crossbreds. Yet, a high variation in performance among flocks with different degrees of crossbreeding was detected. Data analysis of flocks with permanent performance recording revealed that prolificacy was significantly affected by breed, besides farm and parity. Afec Awassi (B+) ewes had a significantly (p

Available in PDF, EPUB and Kindle. Book excerpt: This book and its case studies focuses on typical local products and breeds, descriptions of the production systems and conservation techniques of endangered breeds/products in the Mediterranean area. Traditional and extensive systems, involving local breeds, which meet the needs of the population requiring safe foods at a reasonable costs, are validated for their specific meaning to the region. It is acknowledged that natural constraints of the Mediterranean area of climate and geography, make it unfavourable to mass production at low cost. Profit related aspects are discussed considering the different economic realities of the northern part of the basin compared to the southern part. Characteristics of typical animal production with consideration for positive and negative impacts on production systems and on the environment as well as the need to adjust to climate uncertainty and seasonal variability of feed resources, is also discussed. A focus is given to the following areas: animal production economy and social impact in the Mediterranean area; utilisation of natural resources and environmental impact of the animal production systems; possibilities for improving traditional systems; quality and traceability of typical products; moving from traditional to certified animal products.
