| 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 |
| The aim of this research is to determine the forage yield, quality and physiology of a Panicum spp. cv. Massai pasture in response to two grazing intensitiesand three irrigation depths. In Tocantins State, the difference between the average monthly minimum and maximum temperature reaches more than 16ºC, evenso, the lowest base temperature observed does not compromise the development of tropical forages. More than 93% of rainfall occurs between October andApril. This way, between May and Septembe ... Status: Completed Start date: Wed Jan 01 00:00:00 GMT-03:00 2014 |
| Forage crops of the genus Brachiaria are the most important for feeding the herd in dairy farming systems in the tropics. B. ruziziensis is recognized as having the best nutritional value but is less productive than other Brachiaria species besides being susceptible to feeding damage caused by spittlebug, thus limiting its use by dairy farmers. The breeding program of B. ruziziensis, carried out by Embrapa in partnership with other institutions, has selected an improved g Status: Completed Start date: Sun Oct 01 00:00:00 GMT-03:00 2017 |
| Grassland intensification strategies such as fertilization and irrigation can be used to shorten the period required for recovery of paddocks under rotational management and thus to increase the productivity. In rotational stocking grazing, the definition of the resting and grazing periods of the paddocks, besides determining the total number of paddocks, exerts a great influence on the quantity and quality of the forage produced. The post-grazing residue, determined by the grazing period and th Status: Completed Start date: Sat Sep 01 00:00:00 GMT-03:00 2007 |
| 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 |
| 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 |
| 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 Status: Completed Start date: Tue Aug 01 00:00:00 GMT-03:00 2017 |
| 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 |
| 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 Status: Completed Start date: Thu Mar 01 00:00:00 GMT-03:00 2007 |
| In Brazil, milk production is practiced by more than one million farmers, mostly smallholders, who have the most important sources of feed for the herd in pasture and forage grass cropping for cut-and-carry. One of the major demands of farmers is on improved forage cultivars for cutting and grazing that can meet the nutritional needs of herds throughout the year. Elephantgrass, in addition to its superior performance in the establishment of cut-and-carry plantations (i.e. green chopped, hay, and Status: Completed Start date: Sun Apr 01 00:00:00 GMT-03:00 2007 |
