The use of nanotechnology has been putting nanoparticles and nanostructures in contact with live organisms in ways not yet fully understood. In agriculture, this interaction can occur on a large scale, such as in the applications of controlled release nanostructure-encapsulated pesticides whose toxicity inherent to the drug release system still requires continual verification. Cases like this have motivated the proposal of this project, whose objective was to evaluate the potential impact on liv

As Brazil increases its production of biodiesel, so does the production of glycerin, a by-product with a high energy value. At the same time, corn, the main energy component in concentrated feeds, in addition to being the ingredient that most increases feed costs, tends to become less available in the market due to its use in the production of alcohol in Europe and the United States. Glycerol, the main component of glycerin, has already been used in some countries, mixed with concentrate for lac

The identification of animals with more efficiency in feed utilization is one of the alternatives to overcome the challenges as increased production costs, increased consumer awareness regarding food safety, animal welfare and environmental impacts of the agriculture and livestock. As feeding expenses account for the main cost of livestock activity, differences among animals in converting diet to beef and milk are of great relevance. Animals that use feed more efficiently need to consume less to

In the past years, Brazil has stood out for its leadership and high competitiveness in food production, a position reached especially due to the substantial efforts put into research, development and innovation, associated with free entrepreneurship, natural favorable conditions, abundant and efficient food production, and governmental efforts, notably those of the Ministry of Agriculture, Livestock and Food Supply (Mapa). However, if on one hand the quantitative issues regarding Brazil's food p

Milk production systems in Brazil are based, for the most part, on the use of tropical grass pastures as the main source of nutrients for animals. Keeping high levels of pasture-based milk production depends on the following factors: supply of forage in quantity and quality, maximum duration of the grazing season, rational use of energy, protein and mineral supplements, and definition of management strategy that aims at productivity by area. Therefore, intensive pasture management results in for

The goal of this project is to develop an integrated database system for the Department of Vegetal Sanity (DSV), the Secretary of Agriculture and Stockbreeding Defense of the Agriculture, Stockbreeding and Provision (Mapa), hoping to facilitate processes of risk analysis of plagues that attack vegetable products. The vegetable product imports which can be potential spreaders of plagues is normatized by the International Plant Protection Convention (IPPC), which is linked to the Committee of Sani
