Abstract:
The silage experiment S-54 was carried out by the Institute of plant production and cultural landscape at the LFZ Raumberg-Gumpenstein. The main objectives of the project were to test the impact of silage additives on the fermentation process, the influence of forage contamination on fermentation and forage quality and the economic effect of silage additives. The effects of different silage additives were examined for differently pre-wilted forage samples. The test product 1 (lactic acid bacteria), EM-Multisil (effective micro-organisms) and BioSil liquid plus (chemical silage salt) were used as silage additives. The forage material origined from the first cut of a permanent meadow and was pre-wilted to 25 % and 32 % DM respectively. The forage samples were conserved in 60 litres barrels, in PVC tower silos with a volume of 250 litres and in 1 litre bottling glasses. Sensoric, micro-biological and chemical analyses were carried out. The pH value was measured by a pH-meter during the fermentation process and after the emptying of the silos. The data were statistically analysed with a one way ANOVA-procedure and in terms of the occurance of butyric acid with a multifactorial procedure (general linear Model) using SPSS. The results of the fermentation acid proportion indicated a mis-fermentation, in general. Only the additive BioSil liquid plus could reliably inhibit the production of butyric acid. The strong forage contamination showed a negative impact on forage quality and led to a very low energy concentration. Only the use of the test product 1 (in the pre-wilted silage) resulted in an economic benefit.
