Integrated control of ectoparasites of veterinary importance is being implemented on a limited basis at present. However, several forces are accelerating a global shift to integrated pest management (IPM). These accelerating forces include the following: reduction in new chemical compounds registered for use on livestock and poultry universal development of resistance to pesticides heightened e...
What is the future for livestock agriculture in the world? Consumers have concerns about sustainability but many widely used livestock production methods do not satisfy consumers' requirements for a sustainable system. However, production can be sustainable, occurring in environments that: supply the needs of the animals resulting in good welfare, allow coexistence with a wide diversity of orga...
The huge changes in agricultural activities, which may be amplified by the forthcoming Common Agriculture Policy reform, call the future of crop-livestock systems into question and hence the impact of these changes on landscapes and biodiversity. We analyzed relationships between agriculture, landscape and biodiversity in south-western France. The study area covered about 4,000 ha and included ...
Traceability of a food consists of development of "an information trail that follows the food product's physical trail". Internationally, the US is lagging behind many countries in developing traceability systems for food in general and especially for livestock, poultry and their products. The US food industry is developing, implementing and maintaining traceability systems designed to improve ...
Silvopastoral systems present important opportunities for increasing food production from animals. This is justified by the widening gap between production and consumer requirements, and the inability of domestic supplies to meet the projected demand up to year 2020 for foods of animal origin. Increasing productivity from animals thus necessitates the development of all possible avenues of food...
Sustainability of livestock production systems (LPSs) is of prime importance to the needs of human beings. From a sustainability point of view, an LPS is sustainable when it is environmentally nondestructive, economically viable and socially provides appropriate quality of life for producer and the whole community. Iran LPS is primarily based on traditional production systems. Therefore, an imp...
Eco-efficiency is concerned with the efficient and sustainable use of resources in farm production and land management. It can be increased either by altering the management of individual crop and livestock enterprises or by altering the land-use system. This paper concentrates on the effects of crop sequence and rotation on soil fertility and nutrient use efficiency. The potential importance o...
This Special Issue of Bioresource Technology is dedicated to selected contributions presented at the international Workshop: ‘‘Livestock waste treatment systems of the future: A challenge to environmental quality, food safety, and sustainability,” held 2–4 April, 2008, in Florence, South Carolina (USA) and sponsored by the OECD (Organisation for Economic Co-operation and Development), Cooperati...
Pathogenic animal trypanosomes affecting livestock have represented a major constraint to agricultural development in Africa for centuries, and their negative economic impact is increasing in South America and Asia. Chemotherapy and chemoprophylaxis represent the main means of control. However, research into new trypanocides has remained inadequate for decades, leading to a situation where the ...
