Sheep and goats are of ancient origin in Southern Africa and date back more than 2000 years. Topography and soils influence animal production directly. Infectious diseases and internal and external parasites are severe constraints in sheep and goat production and they are endemic to large regions in Southern Africa. In financial terms it is calculated that reproduction is twenty times more important than carcass qualities, and ten times more important that those characteristics associated with growth and feed conversion. The reproduction tempo further determines the intensity of selection that can be applied and consequently the genetic advances that can be made. As reproduction has a low heredity (10%), (Maree and Casey, 1993), it is the reproduction tempo that determines the financial and economic success. By today's standards of world population and settlement density, it is no longer possible of making way with ample compensation. New agricultural ways had to be found, supported by technical and veterinarian developments. What once was a visionary dream - improving food production enhanced by pharmaceutical influence - has become a real possibility. Obviously this led to, and will lead to, a search for answers. Recommendations formulated in many ways have already confronted one another, not only in past years. Finding correct solutions depend on how the human community reacts to such a challenge, and organizes its production, and agricultural process. The lack of significant improvement regarding the everincreasing demand for mutton meat has been of concern for some time. Increased economic pressure calls for intensifying the production of ewes. For increased flock fertility, adaptability and reproduction efficiency are major factors. From an economical point of view, a high fertility with regular lambing under good breeding conditions and speedy weight increase is seen as a very important criterion in Small Stock production. The associated problems of low live mass weight are known: weak lambs, poor survival chances and an increased mortality.

The Food and Agriculture Organization of the United Nations (FAO) produced a 2011 report on women in agriculture with a clear and urgent message: agriculture underperforms because half of all farmers—women—lack equal access to the resources and opportunities they need to be more productive. This book builds on the report’s conclusions by providing, for a non-specialist audience, a compendium of what we know now about gender gaps in agriculture.

Air Emissions from Animal Feeding Operations available in PDF, EPUB and Kindle. Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.

Download and read online ebook Microlivestock write by Board on Science and Technology for International Development. This book was released on 1991-01-15. Microlivestock available in PDF, EPUB and Kindle. Microlivestock is a term coined for species that are inherently small as well as for breeds of cattle, sheep, goats, and pigs that are less than about half the size of the most common breeds. These miniature animals are seldom considered in the broad picture of livestock development, but they seem to have a promising future, especially in developing nations or wherever land is scarce. This book raises awareness of the potential of these small species, including microcattle, microsheep, various poultry, rabbits, rodents, deer, antelope, and lizards. It also strives to stimulate their introduction into animal research and economic development programs.

Download and read online ebook Global Livestock Production Systems write by Timothy P. Robinson. This book was released on 2011. Global Livestock Production Systems available in PDF, EPUB and Kindle. Informed livestock sector policy development and priority setting is heavily dependent on a good understanding of livestock production systems. In a collaborative effort between the Food and Agriculture Organization and the International Livestock Research Institute, stock has been taken of where we have come from in agricultural systems classification and mapping; the current state of the art; and the directions in which research and data collection efforts need to take in the future. The book also addresses issues relating to the intensity and scale of production, moving from what is done to how it is done. The intensification of production is an area of particular importance, for it is in the intensive systems that changes are occurring most rapidly and where most information is needed on the implications that intensification of production may have for livelihoods, poverty alleviation, animal diseases, public health and environmental outcomes. A series of case studies is provided, linking livestock production systems to rural livelihoods and poverty and examples of the application of livestock production system maps are drawn from livestock production, now and in the future; livestock's impact on the global environment; animal and public health; and livestock and livelihoods. This book provides a formal reference to Version 5 of the global livestock production systems map, and to revised estimates of the numbers of rural poor livestock keepers, by country and livestock production system.
