The Quality of Fermentation Process of High Moisture

Abstract

The objective of this research was to find the influence of different silage additives on the quality of fermentation process of ensiled high moisture crimped corn. Three variants were examined: untreated control (UC) variant in which was high moisture corn conserved without additives, and experimental variants A and B. In these variants different silage additives (bacterial inoculant in variant A and combined biochemical additive in variant B) were applied. After 6 months of silage fermentation process the average samples for the fermentation products content were determined. The highest lactic acid content was found in untreated control variant (24.27 g/kg of dry matter). After the silage additives application lower acetic acid content was found (2.87 in variant A and 2.82 g/kg of dry matter in variant B). Undesirable butyric acid content was generally very low. The lowest value (significantly at P<0.01) of titration acidity was determined in variant B. The value of active acidity (pH) of water extracts of silages were from 3.70 (variant B) to 3.75 (variant UC), without statistical differences. In variants conserved by additives lower ammonia content as well as total alcohols were found. In comparison with untreated variant (UC) we didn’t find in top of silage profiles of experimental variants B sensory occurrence of fungi.
