Summary

Descripción general del contenido del recurso.

Maize and sorghum silages are good sources of energy for lactating dairy cows that produce milk destined for fresh and matured cheeses. Silages are usually stored in horizontal silos with or without side walls on commercial farms throughout the world. The main microbiological and nutritional quality problems are related to harvesting time, ensiling technology, and management practices during filling and feed-out. Aerobic deterioration is a key point that must avoided on farms in order to improve the hygienic, chemical and sensorial quality of milk and cheeses. Aerobic deterioration causes large losses of dry matter (DM) and quality, and it can cause health problems for animals and humans through the transfer of pathogens and mycotoxins from feed and livestock to food products. The objectives of the present work were to overview management practices connected to the storage of maize and sorghum in horizontal silos on farms producing milk for make Protected Designation of Origin (PDO) hard ripened cheese, to define good management practices that should be applied as the basis for safe silage production and to reduce the extent of aerobic deterioration.<br>As silagens de milho e de sorgo são importantes fontes de energia em rações utilizadas na bovinocultura leiteira, sendo que a estocagem desses volumosos é realizada em silos horizontais com ou sem a presença de paredes laterais (trincheira ou superfície, respectivamente), os quais são atrativos em razão do baixo custo de armazenamento, porém suas conformações determinam grande superfície de exposição, o que torna as silagens mais susceptíveis a deterioração aeróbia. Os maiores problemas envolvendo a qualidade microbiológica e nutricional em silagens, estão relacionados às práticas de manejo na colheita, no abastecimento e compactação da massa, na vedação e, principalmente, durante o desabastecimento do silo. O controle da deterioração aeróbia em silagens pode ser o principal ponto para melhorar a qualidade química, sensorial e higiênica em queijos e no leite fresco. A deterioração aeróbia causa perdas nutricionais e de matéria seca (MS), podendo provocar efeitos indiretos ao animal e ao homens pela transferência de microrganismos patogênicos e micotoxinas ao longo da cadeia alimentar. O presente trabalho tem por objetivo discutir práticas de manejo em fazendas que utilizam silos horizontais no armazenamento de silagem de milho e de sorgo e que produzem leite destinado à fabricação de queijos (tipo pasta dura) que possuem Denominação de Origem Protegida, além de definir aspectos ligados ao manejo na produção de silagens e no controle da deterioração aeróbia das mesmas.
