As a result of the research it was revealed that application of the ferment preparation Vitazim in a dose of 500 g/t at feeding of hens-layers promoted increase in egg efficiency at 14.8%, egg mass - on 4%, safety increase - on 1% (93.6% against 94.6% in the control). Expenses of forages for 1000 eggs have made 1.35 c (against 1.53 c in the control) and have decreased on 11.8%. The ferment preparation Vitazim applied in poultry feeding in order for increase of the efficiency, natural resistance of an organism, safety of young growth, eating improvement and comprehensibility of forage nutrients, reduction of the expense of forages.
