Effect of antinutritive factors in the feed (physic acid, nonstarch polysaccharides) and kind of trace element forms (inoranic vs organic) was presented on the basis of literature review. Phytic acid, through formation of indegistible complexes with microelements, significantly decreases its utilization by the organism. Also non-starch polysaccharides showed often similar influence. Organic forms of trace elements generally are characterized by higher bioavailability than their inorganic forms
