The present invention relates to biotechnologies and is intended for the field of feed production and may be applied for producing fermented feed of plant origin with high antimicrobial activity. The aim of the invention is production of the plant fermented feeds of high biological activity by using the newly selected lactic acid bacteria (LAB) strains Pediococcus acidilactici BaltBioOl MSCL P1480 and/or Pediococcus pentosaceus BaltBio02 MSCL PI 481. These said LAB strains have been isolated from the Lithuanian cereal raw material and tested, are microbiologically safer, have high biological activity and improve the health status of animals, increase their yield and may be successfully used in fermented feed production. The proposed composition of the mix. The proposed wheat-barley optimal substrate composition intended for ruminant animal feed. The presented products of fermentation, drying, forming and storage conditions, the bioactive properties of the finished products, such as LAB colony-forming units (CFU). Identified CFU values and changes in drying and depositing.
