Lundmark, Cecilia, 2005. Ensiling experiment in bagged silage with 3 silage additives. SLU, Dept. of Animal Nutrition and Management (until 231231), Uppsala. Uppsala: SLU, Dept. of Animal Nutrition and Management (until 231231)



The aim with this project was to test the effect of three different silage additives with respect to the chemical quality of the resulting silage. The 3 additives tested were Kofasil Ultra, Kofasil Life and AIV 2S. The additive-treated silages were compared with each other and also with untreated silage (no additive).
The experiment was performed on July 22, 2004 at Kungsängen Research Centre in Uppsala. The silage bag that was made had a total length of 48 m and a theoretical diameter of 2.44 m (8 feet). The different additive-treated forages were fed into the bag in approx. 5 m long sections (3 sections/additive). Sections were separated by layers of rolled barley. Unloading was performed during a cold period between Jan. 3rd and Jan 7th, 2005. Samples were cored out with a drilling-machine and analysed with respect to contents of dry matter, ash, sugars (WSC), metabolisable energy, ammonia nitrogen, pH, fatty acids, ethanol and clostridial spores (Clostridium spp.).
Acceptable silage quality was produced in the untreated control silages (no additive), but all additive-treated silages were of better quality than the control silages. The best silages qualities were achieved with the additives Kofasil Ultra and AIV 2S.


Målet med projektet var att testa tre olika ensileringsmedel med avseende på ensilagets
kemiska kvalitet. De tre ensileringsmedel som testades var Kofasil Ultra, Kofasil Life och
AIV 2S. Ensilage behandlat med de olika ensileringsmedlen jämfördes mot varandra samt
mot obehandlat ensilage.
Experimentet startade den 22 juli 2004 vid Kungsängens Försöksstation i Uppsala. Ensilage
tuben som lades hade en total längd på 48 m och en teoretisk diameter på 2,44 m. Ensilage
som behandlats med olika ensileringsmedel skildes åt i tuben med hjälp av kornkross. Tuben
tömdes mellan den 3: e och 7: e januari, 2005. Prov på ensilaget togs med en borr och proven
analyserades med avseende på TS, aska, WSC, ME, ammonium-kväve (Am-N), pH, fettsyror
(FA), etanol och klostridiesporer.
Kvaliteten på det obehandlade ensilaget var acceptabel, men allt ensilage som behandlats med
något av ensileringsmedlen var av bättre kvalitet än det obehandlade ensilaget. Den bästa
ensilage kvaliteten återfanns då ensilaget behandlats med Kofasil Ultra och AIV 2S.
