Studies on risk factors in dairy herds and their economic impact are available in countries with developed dairy production. This information is used to direct and prioritize procedures that improve herd health and avoid problems such as high total bacterial count and presence of antimicrobial residues in milk. In countries with developed dairy farming most herds are comprised of high-producing animals of specialized breeds and raised in total or partial confinement systems. In Brazil, there is

Waste recycling is common in agriculture nowadays on different scales, depending on chain organization, available technologies, and environmental and health regulations. Just to mention two figures, in 2009 the sugarcane-ethanol chain produced 604 billion liters of vinasse and 201 million tons of bagasse and filter cake. Although the bagasse is burnt to generate energy and the vinasse is a fertilizer, many challenges remain. The objective of this project is to assess the potential to transfor

The adoption of Good Laboratory Practices (GLP) contributes to the development of scientific research, as they result in greater reliability and efficiency of the results. In order to follow some of the current standards, such as GLP or ISO 17025, the laboratory must adopt measures of organization, control, training, standardization and registration of its activities. The laboratory must also adopt practices that guarantee the safety of its personnel and the community in general. Among these is

This project aimed to present reuse alternates for the waste produced in the industrial processing of açaí, and thus obtain processing plants that minimize the release of waste products. A previous evaluation of this matter pointed out technological alternatives through which would be possible to: I) reuse the residue inside or outside the processing plant, or, II) produce byproducts with aggregated value. The project proposed to develop support technologies to the açaí agroindustrial complex, w ...

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

The process of organic waste biodigestion is quite old, as the first unit was installed in Bombay, India, in 1819; in Australia, a company has produced and industrialized methane from sewage since 1911. China has 4.5 million biodigesters that produce gas and organic fertilizer, the main role of which is sanitation in rural areas. However, different aspects related to biodigesters are still lacking. This work aimed at studying and improving a biodigester system, and its general goal was the devel

Grassland intensification strategies such as fertilization and irrigation can be used to shorten the period required for recovery of paddocks under rotational management and thus to increase the productivity. In rotational stocking grazing, the definition of the resting and grazing periods of the paddocks, besides determining the total number of paddocks, exerts a great influence on the quantity and quality of the forage produced. The post-grazing residue, determined by the grazing period and th

The Lower Tocantins region, PA, presents agricultural traits that integrate both traditional and modern practices; the small farming's main activities are concentrated on yuca cultivation and flour processing. In the county of Moju, the productivity obtained by the great majority of small farmers oscillates between 9 and 16 tons/hectare, once great part of them do not select propagation material, do not control weed growth and don't cultivate using adequate spacing. Moreover, other common farmin
