This year, 30 million acres of the corn, cotton, and potatoes planted in the United States will have been genetically engineered to produce an endotoxin normally found in the microbe Bacillus thuringiensis (Bt), a self-contained pesticide that will be toxic only to target insects. Transgenic pest-resistant crops are a cost-effective alternative to chemical pesticides, and may offer a way to hel...
The review presents results of recent life cycle assessment studies aiming to quantify and improve the environmental performance of UK poultry production systems, including broiler meat, egg and turkey meat production. Although poultry production has been found to be relatively environmentally friendly compared with the production of other livestock commodities, it still contributes to environm...
mycotoxins are secondary metabolites of molds and have adverse effects on humans, animals, and crops. those can cause illnesses and economic losses. aflatoxin m1 (afm1) is one of the mycotoxins produced from the hydroxylated metabolite of aflatoxin b1 (afb1). it can be found in milk or milk products obtained from livestock that have ingested contaminated feed. in this paper, recent studies were...
Feeds contribute highly to environmental impacts of livestock products. Therefore, formulating low-impact feeds requires data on environmental impacts of feed ingredients with consistent perimeters and methodology for life cycle assessment (LCA). We created the ECOALIM dataset of life cycle inventories (LCIs) and associated impacts of feed ingredients used in animal production in France. It pro...
Argentina is the second largest grower of genetically modified (GM) crops. This high level of adoption of this new agricultural technology is the result of a complex combination of circumstances. We can identify four main causes that led to this: political support (from agriculture officials), ability to solve prevalent farmers' needs, economic and environmental factors and an early implementat...
Aquaculture is the fastest growing food sector and continues to expand alongside terrestrial crop and livestock production. Using portfolio theory as a conceptual framework, we explore how current interconnections between the aquaculture, crop, livestock, and fisheries sectors act as an impediment to, or an opportunity for, enhanced resilience in the global food system given increased resource ...
There has been a permanent selection for thousands of years to create new varieties of plants to supply better feeds for animal nutrition. Selection purposes may result in an increased dry matter yield per hectare, an altered dry matter composition, an improved organic matter digestibility and consequently an increased energy value, a reduction of the presence of anti-nutritional factors or a b...
Traceability of GMO food and feed is a growing request among the European populations and the European Community has responded by providing a complex set of EC Regulations on GMO traceability, detection and labelling, to ensure that the general public is able to make an informed choice about the food they eat. Despite the efficiency and sensitivity of modern GMO detection methods, the regulatio...
Biotech crops are the fastest adopted crop technology in the history of modern agriculture. The commercialisation of GMO is in many countries strictly regulated laying down the need for traceability and labelling. To comply with these legislations, detection methods are needed. To date, GM events have been developed by the introduction of a transgenic insert (i.e., promoter, coding sequence, te...
It is widely assumed that food production must increase by 70% to feed the growing world population and accordingly that further industrialisation of livestock production is essential. This would result in poorer animal welfare as even with good stockmanship industrial systems generally have a low potential for delivering satisfactory welfare outcomes. In fact a large increase in food productio...
