FIELD: biology. SUBSTANCE: method involves combination of polyelectrolyte complex of sodium dodecyl sulfate and copolymer of N-vinylpyrrolidone and N,N,N,N-triethylmethacryloylhydroxyethylammonium chloride at their molar ratio 3.6-4.0:1 with magnesium sulfate or zinc sulfate, or cobalt chloride at molar ratio of metal salt and sodium dodecyl sulfate 11.5-46.0:1; 0.17-0.68: 1; 1.06-4.24: 1, respectively. Proposed complex ensures to increase growth-stimulating activity (animal mass - by 59% and linear size - by 75%). EFFECT: increased effectiveness of method. 4 cl, 2 tbl
