SUBSTANCE: invention relates to animal feed industry and can be used for producing high-performance feed. Method of producing feed additive involves dissolving vegetable phospholipids, diacetophenonylselenide, beta-carotene, vitamin E and vitamin C in vegetable oil in two steps and application of obtained solution on carrier. At first stage in vegetable oil is introduced beta-carotene at temperature 90-95 °C, stirred for 30-35 minutes and cooled to temperature of 45-50 °C. At second stage is introduced vegetable phospholipids, diacetophenonylselenide, vitamin E and vitamin C, stirred for 20-25 minutes, cooled to temperature of 20-25 °C. Further, obtained solution is applied on carrier, which is a mixture of chalk and wheat bran preliminarily treated at temperature 100-105 °C during 30-40 minutes and cooled to temperature of 20- 25 °C. Feed additive for laying hens, obtained using said method, consists of diacetophenonylselenide, beta-carotene, vitamin E, vitamin C, vegetable phospholipids, vegetable oil and carrier. Carrier for feed additive used is a mixture of chalk and wheat bran. All components of feed additive are used in a certain ratio.

EFFECT: feeding with obtained feed additive ensures higher productivity of laying hens and higher category of quality of eggs.
