Dairy Cattle Farming represents one of the most important alternatives to migrating slash-and-burn agriculture in the Amazon, and lately, has been suffering a process of intensification. This activity has presented in the last years significant growth rates in the northern region, being thus one of the greatest in the country although it remains as the region with the smallest aggregate production. However, this evolution is predominantly a result of the increase in the dairy cattle herd and in

In the context of planning, managing and generating territorial knowledge, Geoprocessing plays a fundamental role in supporting strategic decision making through the treatment of georeferenced information, which is the object of interest in public and private institutions and organizations. The structure of databases provided by the Geographic Information Systems (GIS) is configured as a cartographic information generator to support the various productive chains of the agricultural sector, leadi

Failures to transmit information significantly impair the coordination and interaction between the different agents in the milk production chain. A large number of nationally based companies and a myriad of producers and policy makers face the challenge of structuring themselves for competition in a globalized business world. The main objective of the project was to provide information, structural analysis and monitoring of conjunctural developments in the milk production chain, in order to meet

This project aims to develop an enzymatic route for biodiesel production, using ethanol and palm oil as raw materials. Currently, biodiesel is obtained by a chemical reaction between an oil and an alcohol, accelerated by a chemical catalyst - mainly sodium hydroxide. The use of this catalyst, however, causes a number of problems, such as high energy consumption, difficult glycerol recovery and the generation of a large volume of effluent. In addition, it causes saponification when acid oils, suc

The emission increase of greenhouse effect gases and the high petroleum prices have elevated the demand for renewable fuels. For diesel, the most used fuel in the country, the main option has been the use of vegetable oil and animal fat by-products. However, there are two major problems regarding the production of vegetal oils which could hinder the use of these products as fuel: the quality and the quantity of oils produced. Of all the cultivated species, only the palm oil has the needed produc

The project aimed to study the use of crude glycerin produced by biodiesel plants as feed for dairy cows as an alternative to reduce the use of maize, an energy source with increasingly higher international prices, and thus increase the sustainability of dairy production. Research work carried out in other countries suggests that glycerol is the main component of crude glycerin, an energetic nutrient efficiently used by ruminants. . Thus, this project considered three main strategies to address

The growing biofuel industry generates by-products that have shown promise as energy and protein feeds in ruminant diets. The objective of this project was to determine the effects of by-products of biodiesel production, obtained from different sources of oilseeds, on the in vitro degradability of nutrients, in vitro ruminal fermentation and methane gas production. Palisadegrass ( Brachiaria brizantha) was used as a model. Its isolated incubation was considered as a contro ...

Riverside communities experience many deficiencies in electricity supply and basic sanitation. Regarding forest products management there is a dependency of açaí and limited use of other species. Thus, the project located at Ilha das Cinzas – Pará state, aims to: evaluate agroforestry systems with ‘pau mulato’ and other arboreal and agricultural species; generate actual technical indices to the management of native açaí grooves through its mapping and monitoring along with participating families ...
