Abstract
Efficient technology was developed for obtaining water extracts and dry additive to mixed feed, containing a complex of biologically active substances, from larch biomass (wood and bark) processing. It was established by means of HPLC, UV, IR and 13C NMR spectroscopy that polysaccharide arabinogalactan dominates in the extracts. In addition, the extracts contain dihydroquercetin, tannins and other polyphenol compounds, as well as pectin compounds. Experimental lots of products were manufactured according to the developed technology; the efficiency of their use for growing young agricultural animals was demonstrated.
