METHOD FOR INCREASING FEED DIGESTIBILITY WHEN INTRODUCTION INTO THE RATION OF BULL-CALVES IN FATTENING ULTRAFINE PARTICLES OF SILICON DIOXIDE

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the agriculture. Method for increasing feed digestibility involves introduction into the ration of bull-calves in fattening ultrafine particles SiO₂ with hydrodynamic radius 388±37 nm in dose of 13 mg/kg of fodder.;EFFECT: increased experimentally in vitro digestibility by 4,6 %, in situ study by 5,6 % in 3 hours of exposure in the rumen in comparison with the control, the degree of toxic elements in cattle cicatricial fluid decreases.;1 cl, 3 tbl
