This book was released on 2015-06-19 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agrocolture and food security are of particular concern for the countries of the Middle East and North Africa (MENA) region, and represent one of the biggest challenges facing the area. As a consequence of the region’s heavy reliance on food imports, the sharp increase in food prices since 2007 and the consequent world food crisis has had macro-economic problems (inflation, trade deficits, fiscal pressure), increased poverty and political instability. This challenge, coupled with the consequences of environmental degradation, water scarcity, urbanization and climate stress, call for the urgent development of sustainable agriculture has mostly been ignored in Euro-Mediterranean relations, due to strong opposition from the EU. However, academics and policymakers have increasingly acknowlendged that agriculture that needs to be placed at the core of Euro-Mediterranean regional cooperation. Given the sensitiveness and strategic importance of agriculture for both shores of the Mediterranean, the IAI and the OCP Policy Center jointly organized a two-day conference in Rabat on November 20-21, 2014, to discuss food security and agriculture challeges in the framework of Euro-Mediterranean relations. The present colume collects the updated and revised versions of the twelve papers that were discussed in that meeting.

Download or read book INRA feeding system for ruminants written by INRA and published by BRILL. This book was released on 2023-11-27 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: The INRA Feeding System for Ruminants has been renewed to better address emerging challenges for animal nutrition: prevision of productive responses, product quality, animal health and emissions to the environment, in a larger extent of breeding contexts. The new system is mainly built from meta-analyses of large data bases, and modelling. The dietary supply model accounts for digestive interactions and flows of individual nutrients, so that feed values depend on the final ration. Animal requirements account for variability in metabolic efficiency. Various productive and non-productive animal responses to diets are quantified. This book presents the whole system for dairy and meat, large and small ruminant production, including specificities for tropical and Mediterranean areas. The first two sections present biological concepts and equations (with their field of application and statistical accuracy) used to predict intake (including at grazing) and nutrient supply (Section 1), animal’s requirements and multiple responses to diets (Section 2). They apply to net energy, metabolisable protein and amino acids, water, minerals and vitamins. Section 3 presents the use of concepts and equations in rationing with two purposes: (1) diet calculation for a given performance objective; and (2) prediction of the multiple responses of animal to diet changes. Section 4 displays the tables of feed values, and their prevision. All the equations and concepts are embedded in the fifth version of INRAtion® software for practical use.

This book was released on 2012-12-06 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two questions could not be avoided in the avant-propos of this book; (i) what is the importance to man of ruminant livestock, and (ii) what results of practical relevance in the growing mountain of scientific verbiage could be found in the Proceedings of this Symposium. Herbivores are an integral and critical part of the natural ecosystem which must be preserved because of their impact on human welfare. Wh at makes ruminants especially important to man is that they can thrive on fibrous forage and are thus the only viable enterprise over much of the earth's surface where crop growing is impracti cable. They contribute a wide array of products in addition to 50000 000 tonnes ofmeat (1977) and represent a 'capital reserve' that can be drawn upon in times of emergency: milk for example (450000000 tonnes) can make the difference between subsistence and starvation. About 60% of the world's meat and 80 % of the milk are produced by one third of the world ruminant population in the developed regions and as much as 99 % of the power for agriculture is provided by the ruminant population in developing countries. For the next two decades, a probable increase by 30 % for . cattle and buffalo and more than 40 % for sheep and goats is expected by improving health, fertility, nutrition and genetic potential rather than feed resources.

Download or read book Prospects for a sustainable dairy sector in the Mediterranean written by M. Djemali and published by BRILL. This book was released on 2023-08-28 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dairy products have always constituted an essential component in the Mediterranean diet. In addition to their nutritional values, they represent also a part of the cultural heritage of the people. Prospects for a sustainable dairy sector in the Mediterranean, preconditions for its development and the future consumers' demand were some of the issues covered by the papers presented at the EAAP - CIHEAM - FAO Mediterranean symposium. It was organised by the Tunisian Office for Livestock and Pastures and the National Agronomic Research Institute and sustained by the Government of Tunisia, FAO, ICAR and CIRVAL. Over 280 participants from 25 countries participated. The symposium identified a variety of technically viable and scientifically sound policy options and defined the main fields requiring further scientific research and the development of new sustainable technologies. The available technologies to address intensive, semi intensive and extensive production systems and the existing institutional framework (research, education, extension systems, organisation of the sector), although requiring continuous adjustments and improvements, have proved to be in a position to meet a variety of demands and challenges. In this respect, the Symposium called for an increase in research for the semi-intensive farming systems in the South and emerging issues resulting from changes in agricultural policies in the North. It emphasised the importance of producers1 associations as representatives of the interests of the sector and partners in the overall dialogue on policy matters and in the identification of research needs. The Symposium confirmed the wish and capacity of the dairy sector in the Region to contribute to the sustainable rural development, to the creation of new employment opportunities and to the reasonable and harmonious management of the natural resources.

Download or read book Alternative and Novel Livestock Feed Reducing Environmental Impact written by Francesco Serrapica and published by Frontiers Media SA. This book was released on 2024-07-29 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Livestock production systems are generally considered to have various negative environmental impacts, including nutrient leaching, and a significant contribution to global warming. In this respect, the reduction of gas or ammonia emissions can be achieved through improved efficiency in the choice of feedstuffs. The use of alternative feeds or additives can contribute to a more energy-efficient ration with lower emissions. Such strategies can contribute to improved animal production and health status. Studies have reported that feed additives such as nitrogen-containing compounds, probiotics, prebiotics, and plant extracts significantly reduce ruminant methane. Moreover, research suggested that fruit pomaces could be a low-cost fibre source in poultry nutrition, and that the inclusion of orange pulp in pigs’ diets can reduce the potential ammonia and methane emissions. To properly evaluate the most adequate reuse strategy it is necessary a specific life cycle assessment for each co-product.
