Productive and biological indices of "ISA" crossing broilers when including the Khakass bentonites into their diets

The Khakass bentonites as mineral fodder additive to the main diet of "ISA" crossing broilers (from 1 to 4 % on the mixed fodder mass) are studied. The increase of broiler live weight by 9,1 and 5,9 %, 100 percent livestock preservation, improvement of hematologic indicators when including 2 and 3 % of bentonites to the main diet are established.
