The general objective of this project was to identify microbial strains that produce enzymes capable of degrading fibers or hydrolyzing secondary anti-nutritional compounds, aiming to identify microbial isolates (rumen bacteria or fungi) with fibrolytic capacity or tolerant to anti-nutritional factors, as well as to expeditiously isolate and characterize fibrolytic enzymes. It was also the objective of this project that the use of laboratory procedures would serve to train undergraduate and grad

Silvopastoral systems may be an option to prevent grassland degradation because of the potential to control erosion and the ability of some tree species to add nitrogen and other nutrients to pasture, improving soil fertility. In view of this potential, in-depth evaluations of the soil and plant components of these systems are critical. The objective of this project was to verify the effect of trees on soil quality (fertility, biomass and microbial activity) and to evaluate the dry matter produc

Among the existing grass as alternatives to pasture-based production, the genus Cynodon (stargrass and bermudagrass) has advantages such as high productivity and forage quality, responsiveness to fertilization, resistance to cattle trampling, adaptability to a wide range of soil and climate conditions, and good tolerance to waterlogging and low temperatures. These factors distinguish Cynodon from other grasses predominant in tropical conditions and justify considering such specie

Cereal such as wheat, rice, corn, maize, oats, sorghum, millets, triticale, and rye make up the base of human and animal foods and feeds, respectively. Many of these species contribute significantly to the sustainability of agricultural production systems in Brazil, generating jobs and boosting the country's economy. Collectively, these cultures add up to 19 millions of cultivated hectares and 47 million tons of produced grains, which is almost half of the country's total grain production. Howev

In the last century, the wide use of Guzerá breed in crossbreeding led to the expressive reduction of their effective population size, to worrying numbers. Due to its adaptation to diverse environmental conditions, its potential for dual-purpose production (i.e. meat and milk), and its risk of extinction, in 1991, this breed was included by FAO (Food and Agriculture Organization of the United Nations) in the list of genetic resources to be preserved. In view of this, and due to the demand for br ...

The limited knowledge concerning the diversity of species of fruit fly species (Diptera: Tephritidae), on top of the reduced number of researchers working on this biological group in the Amazon region, has motivated the structuring of the Amazonian Network of Fruit Fly Research, a project financed by Embrapa (Call 05/2006 - "Agrofuturo"; SEG code 02.06.05.003), for the period of 36 months (August/2007 to July/2010). The Network has Embrapa Amapá as executing institution and gathers researcher

Yuca ( Manihot esculenta) represents one of the main food products of the Northern region. Indigenous peoples have left to the Northern peoples this heritage of many alternatives to the processing of this root, which can generate up to 300 products according to sources. In addition to having great socio-economic importance to the region, it is estimated that the yuca has its origin and diversification center in the Amazon. Thusly, knowing the existing variability in material collected thr ...

Despite the growth in the production and productivity rates of dairy farming in Brazil, the globalization of the economy, the fluctuations in domestic and foreign food prices, the changing feeding habits of the population, with the growing interest in functional foods as well as foods from agroecological or organic production systems, coupled with the strong demand for genetically improved and adapted animals, are relevant factors that have challenged research and development agencies in proposi

The project consists of studying the parasitic communities of fish species such as catfish and scales fish in the Amazon River system. The main points of analysis are the description of these parasitic communities, description of new species and checking whether the size of the host fish has an influence on the abundance of these parasites, their diversity, seasonal variation and their dispersion in the fish. The parasitic communities of different species of fish will be compared, as well as
