Belarusian-Israeli joint venture FA-uN, LLC offers a highly effective water-soluble biopreservative «SILA-PRIME». The composition of the preparation was developed with the participation of Israeli scientists.

The 8-strain biopreservative «SILA-PRIME» поallows to obtain high-quality fodder with an energy nutritional capacity of 1 ton of dry matter not less than 10,5 mJ, additionally preserve 45-56 fodder units, 5-8 кg of protein per 1 ton of conserved fodder.

«SILA-PRIME»accelerates lactic acid fermentation with acidification of the mass to pH 4.2-4.3 within 24-36 hours and suppresses undesirable butyric acid fermentation.

One gram of the preservative «SILA-PRIME» contains at least
2,5 х 10 10 CFU, and 4.5 grams of the biopreservative is enough to process
1 ton of ensilaged raw materials.

Bio-preservative "SILA-PRIME" (power-prime) is the best preservative for silage and haylage harvesting.

Welcome to the JV FA-uN

Enterprise JV FA-uN, LLC located in the free economic zone “Brest” presents you the biopreservative “SILA-PRIME” which is among the most modern and highly effective biological preservatives. According to the conclusion of the Scientific and Practical Center of the National Academy of Sciences of Belarus on Animal Husbandry this preparation is the most competitive in terms of the quality-to-price ratio among the CIS countries admitted to the markets.


JV FA-uN, LLC was awarded gold medals of the Russian agro-industrial exhibition “Golden Autumn” for the development and production of highly effective biopreservative “SILA-PRIME” for conservation of fodder.

The advantages of the
preservative “SILA-PRIME” over existing analogues

A unique polyculture
of eight strains of complementary bacteria

A unique polyculture of eight strains of complementary bacteria: Lactobacillus plantarum, Pediococcus pentosaceous, Pediococcus acidilactici, Enterococcus faecium, Lactobacillus casei, Streptococcus lactis, Dried Aspergillus oryzae, Bacillus subtillis can preserve almost any agricultural raw materials, prevents secondary fermentation, has a good probiotic effect.

Exceptional bacterial growth technology

All bacteria that are part of the preservative “SILA-PRIME” are grown in the same fermenter under the same environmental conditions so plastically complement each other during fermentation of fodder and have a high viability during long-term storage.

Advanced preservative dehydration methods

A dehydration of the biopreservative “SILA-PRIME” is carried out by the method of heat dehydration which is an advanced method in the world, providing increased viability of bacteria compared with lyophilic drying (freezing) not to mention liquid preparations or preparations immobilized on dry milk.

Technological capabilities of the biopreservative “SILA-PRIME” provide

Rapid acidification of ensilaged mass at the first stage of ensiling.

Strong and accelerated accumulation of lactic acid in the mixed phase.

Strong and accelerated accumulation of lactic acid in the mixed phase.

Prevention of secondary fermentation at the opening of silo storages.
