Among the essential nutrients, nitrogen (N) is the one with the greatest potential for enhancing forage production. The efficiency of nitrogen uptake is related to the energy supply provided by the photosynthesis. However, recent practices of intensive pasture management have recommended the use of lower post-grazing residues, thus reducing the leaf area of the canopy. The objective of this project was to evaluate the effect of the timing of nitrogen fertilization in association with different d

In intensive milk production systems, planning roughage supplementation is critical to the success of the activity. In Brazil the main forage conservation strategy is ensilage, in which maize is the main crop used, due to its high ensilability and silage nutritive value. However, the oscillation of input prices (fertilizers, pesticides, seeds, etc.) has increased the production costs of such crop, a fact that has been pointed out by farmers as a barrier for the economic viability of the producti

Low productivity of pastures in Brazil is the main cause of poor profitability and competitiveness of animal production systems in relation to other agricultural systems. The objective of the project was to generate technologies in intensive system of livestock grazing using Tanzania grass ( Panicum maximum), Marandu palisadegrass ( Brachiaria brizantha) and Star grass ( Cynodon nlemfuensis) to improve forage production and quality and milk production. To this end, evaluatio ...

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

What is the cost of producing one liter of milk in Brazil? Any answer between R$ 0.10 and R$ 1.70 is true. But, also, it is not essentially true. This occurs for two major reasons, both resulting from a lack of standardization. The first reason is that there is an immense amount of production systems in Brazil, from the South to the North. Therefore, in Brazil, rural properties are not standardized, as in Europe, the USA, Canada and Oceania. Each farm is a farm. The second reason is that there i

Concentrated feeds play an important role in milk production, both from the nutritional as the economic aspects, especially for animal production. The behavior of corn and soybean meal prices, for instance, have an important weight in the formation of milk production costs and consequently on the profitability of dairy farming. The current agricultural markets have shown a rise in prices of these grain-based brans. Milk production in Minas Gerais appears as one of the most important activities f

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 growing competitiveness of the dairy agribusiness increasingly requires improved skills on the part of farmers. The improvement of the productive potential of dairy animals requires more efficient and balanced feeding in order to provide a real increase in production. Whether in the beef or dairy livestock segment, the Brazilian exploratory model combines herd pasture feeding with roughage supplementation in the period of food shortage, as well as energy supplementation. In such a model, the

Water is an important natural resource for the competitiveness of Brazilian agriculture. Since Brazil is rich in this natural resource, to preserve it and keep it in quantity and quality is strategic. Such a competency demands water efficiency, which is the relationship between the amount of yielded products and the amount of water used for such a production. This project evaluates the performance of water indicators from milk pasture-based and confinement-based production systems and of nutriti

The TecRede project aims to generate technologies that would, in a short period of time, the development of tambaqui (Colossoma macropomum) cultivation in cage systems. The project chose the tambaqui to foment the development of cage fish farming since it is a fish native to Amapá, which has favorable domestic and international market demand, with production absorption capacity. The research network intends to determine the standardization of techniques and production systems based on Good Pr
