Hygienic Sanitary and Chemical Composition Estimation of Maize Silage in Dairy Farms in Lithuania

摘要

The aims of this study were to estimate maize silage hygienic sanitary and chemical composition parameters,contamination with mycotoxins in dairy farms in Lithuania.In 2011-2012 were collected maize silage samples from 20 dairy farms: prior to ensiling and after 3 and 8 months of ensiling.The method used to detect of L.monocytogenes from raw and ensiled maize silage-LST ISO 11290-2:1998.For identification of yeasts,moulds,total of microorganisms count were used direct plating and dilution plating.Mould genera and species were estimated PCR and microscopy methods.
