The worldwide demand for meat and animal products is expected to increase by at least 40% in the next 15 years. The first question is how to achieve high-quality, sustainable and safe meat production that can meet this demand. At the same time, livestock production is currently facing serious problems. Concerns about animal health in relation to food safety and human health are increasing. The ...
Frontiers in Livestock Genomics (FLG) provides a venue for investigators to publish basic, applied, and methodological research toward a better understanding of the genetic mechanisms underlying the expression of complex phenotypes in livestock, the effects of domestication and evolutionary processes on genome variability, as well as innovative strategies for the genetic improvement of economic...
This study examines the prospects for strong growth in the supply and demand for animal products worldwide, especially in developing countries, where 80% of the world's population lives. Based on scientific publications, statistics and field observations, it reviews greenhouse gas emission levels from livestock, the ability of ruminant livestock systems to sequester carbon and the capacity of t...
Urban and peri-urban livestock farming in developing countries plays an important role in food security in cities; however it brings with it zoonotic risks. The present study was conducted to identify the most important livestock farming-related zoonotic diseases among the human population in urban and peri-urban areas of Kampala, Uganda and to assess the risks from such farming. A framework fo...
Mountain livestock systems, and particularly those based on breeding small ruminants, traditionally constituted a mainstay element of the local economy in Southeastern Spain's mountainous areas. With the rural exodus, which began in the early sixties, these systems were in critical danger of disappearing, due to, among other causes, the scarcity of shepherds and goatherds, the breakdown of an e...
Livestock have made major contribution to human societies by providing food, shelter, fuel, and services. Sheep and goat are economically important livestock play an important socioeconomic role for small and large farmers in Libya. Small ruminant animal meat is popular for Libyan customers, and demand is particularly high during religious and cultural festivals. Small ruminants is valued fo...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
BACKGROUND With world food demand expected to double by 2050, identifying farming systems that benefit both agricultural production and biodiversity is a fundamentally important challenge for the 21(st) century, but this has to be achieved in a sustainable way. Livestock grazing management directly influences both economic outputs and biodiversity on upland farms while contributing to potential...
