Strategies for nitrogen fertilizer application in tropical forage grasses 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 Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2014
Potential of silvopastoral systems for rearing of dairy heifers: pasture traits, forage intake, enteric methane production and animal performance In dairy livestock systems, heifers are an important component to insure the productive endurance of the herd. Feeding dairy heifers has been based on the use of grass pastures, which undergo degradation process shortly after their establishment. As a result, it has been observed low daily weight gain in heifers. Currently, silvopastoral systems have been suggested as alternative to animal production, in view of their potential benefits such as increased soil fertility, improved forage quality, Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2014
Management of tropical forage grasses with reduced rates of herbicides in integrated crop-livestock systems Society has become increasingly aware of the need to preserve the environment and health, demanding quality standards for food and agro-ecosystems. In this context, the rational use of phytosanitary products guarantees the sustainability of food production systems, mitigating, and even eliminating the effects caused by the indiscriminate use of chemical control. Other relevant aspects to be considered are the benefits arising from the crop-livestock integration that mitigate the negative effects Status: Completed Start date: Wed Aug 01 00:00:00 GMT-03:00 2007
Third breeding cycle of Brachiaria ruziziensis for use of the species in crop, livestock and forest integration systems Pastures assume a prominent position in the Brazilian agricultural scenario. The area occupied by forage plants accounts for three quarters of the national agricultural area. Pasture, as an exclusive food source, is the basis for nearly 90% of the beef consumed in Brazil and most of the milk produced in the country. It is estimated that, in Brazil, the grasses of the Brachiaria genus are cultivated in approximately 84 million hectares. Despite the nationwide importance of this grass for Status: Completed Start date: Sat Dec 01 00:00:00 GMT-03:00 2012
Development of Brachiaria ruziziensis cultivars for crop-livestock integrated systems Pasture as an exclusive feeding source accounts for almost 90% of the beef consumed in Brazil and for most of the nearly 35 billion liters of milk produced annually in the country. It is estimated today that, in Brazil, grasses of the genus Brachiaria are cultivated in approximately 84 million hectares. In Brazil, the most cultivated species of Brachiaria are B. decumbens, B. brizantha, B. humidicola and B. ruziziensis. With the increasing agricult ...

Forage potential and intrapopulacional recurrent selection in Brachiaria ruziziensis Pastures assume a prominent position in the Brazilian agricultural scenario, covering about three quarters of the cultivated area nationwide. In addition to the physical aspect, pastures are the main feeding source for the Brazilian herd. Pastures account for almost 90% of the beef consumed in Brazil and for most of the 21 billion liters of milk produced annually in the country. It is estimated today that in Brazil grasses of the genus Brachiaria are cultivated in approximately 84 millio Status: Completed Start date: Tue Jul 01 00:00:00 GMT-03:00 2008
Strategies for managing tropical grasses on forage production and quality and animal performance 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 ... Status: Completed Start date: Sat Oct 01 00:00:00 GMT-03:00 2011
The potential use of biodiesel by-products as feed supplements and methane mitigators in cattle diets based on tropical forages 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 ... Status: Completed Start date: Wed Aug 01 00:00:00 GMT-03:00 2007
