METHOD OF INCREASING PRODUCTIVITY OF BROILER CHICKENS Russian patent published in 2015 - IPC A23K1/16 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to a method of increasing productivity of broiler chickens, and can be used in poultry breeding for feeding poultry, namely broiler chickens. The method comprises adding to the diet of bioactive feed additive containing selenium with a particle size of 20-70 nm, a complex of vitamins - tocopherol, retinol, thiamine, pyridoxine hydrochloride, nicotinamide, Vicasol, solubiliser Solutol HS-15, and water. The feed additive is an aqueous solution of stabilised selenium particles with size of 20-70 nm, vitamins tocopherol, retinol, thiamine, pyridoxine hydrochloride, nicotinamide, Vicasol and solubiliser Solutol HS-15, taken in a certain ratio. The feed additive is administered together with drinking water continuously during the period from 15 to 42 day of fattening broilers.

EFFECT: invention implementation provides normalisation of metabolism, activation of the antioxidant defence system of the body, increase in feed conversion, which leads to an increase in the dynamics of live weight gain of broiler chickens and increase the efficiency of absorption of feed nutrients.
