The intensification of corn production systems has increased the productivity of this grain, mainly due to the application of nitrogen fertilizers, which has contributed to the increase in farmers' profitability. On the other hand, there are greater environmental impacts, mainly related to the greater emission of nitrous oxide from these systems. In an attempt to reduce this type of impact, synthetic chemical products are being added in small amounts to nitrogenous fertilizers, in order to act i

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 ...

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
