SigLac is a combination of three selected strains of Lactobacillus, one strain of Propionibacterium and fibrolytic enzymes. This combination works synergistically to speed up fermentation, increase lactic acid production, improve dry matter recovery and consequently enhance silage quality. SigLac treated silages produce a moderate amount of acetic and propionic acids during fermentation, which helps in the inhibition of yeasts and molds and improves the stability of silage when it is exposed to air.
