FIELD: agriculture; poultry farming.
SUBSTANCE: invention can be used to increase the productivity of laying hens. The main diet of laying hens is supplemented with a feed additive consisting of a sorbent in the form of shungite-containing mineral raw materials and fucus grits obtained from seaweed, which are mixed in a ratio of 9:1. Shungite-containing mineral raw materials are preliminarily fired to pH=6.5, followed by crushing to particles 0.2-2.0 mm in size to obtain grits. The resulting feed additive is applied in the amount of 1.5-2.0 g per 100 g of compound feed up to 180 days of growing laying hens and in the amount of 0.5-1.0 g per 100 g during the entire subsequent period.
EFFECT: invention will increase the productivity of laying hens by improving the quality of the feed and neutralizing mycotoxins in it.
