The method for producing the feed additive based on the processed conifer needle extracts, which is unique, because it uses the microgranulation of the neutralized conifer needle extract and a water-soluble polymer matrix/binding agent in the form of an aqueous solution, which is combined with the extract; this mixture is then added dropwise to an aqueous solution of a crosslinking agent, whereby sodium alginate or a protein/anionic polysaccharide complex, consisting of gelatin and sodium alginate, is used as the polymer matrix/binding agent, and water-soluble calcium salts are used as the crosslinking agent (the calcium salts ensure the obtainment of an insoluble matrix of microgranules), or a protein/anionic polysaccharide complex, consisting of gelatin and sodium alginate, is used as the polymer matrix/binding agent and water-soluble iron salts are used as the crosslinking agent (the iron salts ensure the obtainment of an insoluble matrix of microgranules). |
