Homofermentative inoculant for improving

fermentation quality in silage made from grass,
leguminous plants and green cereal plants 

Rapid pH reduction for better quality silage and enhanced performance

KOFASIL LAC is an inoculant containing two homofermentative strains of the lactic acid bacteria (Lactobacillus plantarum). These have been specially isolated from silage for use as a silage inoculant and have not been genetically modified.

The use of Kofasil Lac results in an intensive lactic acid formation which drops the pH value quickly and significantly in silage crops (e.g. grass and legume plants). This inhibits the development of undesirable and harmful bacteria such as clostridia and reduces Dry Matter (DM) losses.

Treating forage crops with Kofasil Lac results in high energy, nutrient rich, silage that is perfectly hygienic and is ideal for feeding to high performance cattle.

  • contains osmotolerant lactic acid bacteria with fast growth rate
  • improves fermentation quality and minimises DM losses during ensiling
  • increases DM intake and milk yield
  • improves profitability of cattle production

Range of application

KOFASIL LAC is particularly suitable for improving the fermentation quality of silage made of grass, legumes or their mixtures and green cereal plants.
