ADEXGO REPRO-GO-M is an omega-3 fat-product with special fatty-acid content, with the name “REPRO-GO-M”, which can be successfully used for improving reproduction-biological and fertilization results of monogastric animals (for instance: breeding-sow, broiler and laying hen stocks. The product also has special effect on the feeding of young animals (e.g.: pig). It is known that as a consequence of the corn-soya based feeding, the monogastric animals eat feed, of which fatty-acid rate is n-6:n-3 broader than the optimal; thus their catering is incomplete regarding the physiologically important n-3 fatty-acids (pl. C18:3, C20:5 and C22:6).
