Silage, silage foods primarily of corn and sorghum, has been used for the purpose of offering animals a quality food and, when the technique is well applied, as a way of storing food. With the palatability, high degree of digestibility and good nutritional levels maintained, large numbers of livestock production systems may resort to using fermented foods. Given these features we have the example of chains as the milkmaid, where production systems use the silage in large scale, due to the accelerated metabolism and high energy and protein requirement. The use of silage, balanced diet to animal, includes 10 to 20 kg/day/animal with nutritional characteristics that increase productivity and improve the cost/benefit of commercial farming activities, reducing the cost of animal feed and allowing better results in periods of confinement. So, for the case of foods that guarantee the bulky and protein components of the diet, promoting significant reductions in costs of this productive activity, silages become one of the most attractive nutritional options in world agriculture, being important alternative for producers, and can be highlighted, for example, its ability to increase milk production by up to 30%.
Despite nutritional gains to the flock with the use of ensilage, issues related to care in the processing, storage and use, affect the performance and health of the animals. Keep the environment in anaerobiosis during fermentation and storage, as well as the aerobic stability during the supply phase in the trough, is essential for the preservation of microbiological quality and nutritional value of the ensiled material.
Mycotoxins have been identified in foods intended for animal consumption throughout Brazil; However, the national legislation lays down maximum limits for aflatoxins only tolerable total raw materials used directly or as an ingredient in animal feed. The same occurs in the EU, where there are legal limits for aflatoxin B1.
As this is a topic of great concern worldwide, the Ministério da Agricultura, Pecuária e Abastecimento (MAPA), in 2006, established a working group on mycotoxins in products intended for animal feed, constituting an advance for updating national legislation, taking into account the needs imposed by international trade transactions with a view to protecting the health of animals and humans.
The effects of the use of bacterial Inoculants on aerobic stability of silage may solve some of these problems. The Inoculants to lactic acid producing bacteria have been used with satisfactory results, giving economic return to farmers through improved productivity and quality of your silage material. In this way, it is understood that in order to maintain good quality of silage feed suitable measures are required to prevent animal health problems, as well as economic losses.
With this, the University of Minho has been developing work in the area of removal and inactivation of fungal contaminants and their mycotoxin, now being needed test solutions in field trials. On the other hand, the Universidade Federal Rural do Rio de Janeiro has been working in deployment and establishment of a research and development centre of activities and products involving the area of animal nutrition in the State of Rio de Janeiro. Ongoing research and projects submitted for approval are being developed with the intention of aggregating data in areas little explored in the State, leading to access to this information, as well as advisory services and corrective actions. The research projects will run multi-disciplinary teams that rely on support from funding agencies such as CAPES, CNPq and discuss and FAPERJ thematic mainly related to the areas of nutrition, health, animals, fungi and mycotoxins under the scope of advanced graduation courses of the participating institutions: UFRRJ and University of Minho.
