At a reproduction facility Udinsky JSC (Tatarstan Republic) in hens of Bovans cross it was shown that the patented feed additive Vinivet from renewable by-products of beekeeping given during feeding periods has a positive effect on cellular-humeral resistance factors. Bactericidal activity of the skin grew by 6.2 %, lysozyme activity — by 13.6 %, neutrophils’ activity in spontaneous and stimulated tests increased by 10.9 % and 15.6 %, respectively. At the same time an egg production rate increased by 11.9 % and egg mass by 5.7 %.
