METHOD OF INCREASING PRODUCTIVITY OF BROILER CHICKENS Russian patent published in 2014 - IPC A23K1/16 A23K1/175 A61K31/355 A61K33/04 A61P3/02 

FIELD: agriculture.

SUBSTANCE: invention relates to biotechnology and can be used to increase the productivity of broiler chickens. The method comprises feeding the combined fodder with feed additive comprising selenium with the particle size of 20-60 nm, solubiliser Solutol HS 15 of vitamin E and water in a predetermined ratio, which is administered together with drinking water continuously during 15 to 42 days of broiler fattening at a dose of 0.125 wt.% of selenium and 3.8 wt.% of vitamin E per litre of drinking water. At that the feed additive is an aqueous solution of stabilised selenium particles with size of 20-60 nm, vitamin E and solubiliser Solutol HS 15.

EFFECT: invention enables to normalise metabolic processes, the activate the body's antioxidant defence systems, to increase the feed conversion rate and to increase the live weight gain.
