Recently, in the CIS countries and abroad, to compensate for the mineral deficiency of feed rations and reduce their cost, substances of natural origin have increasingly begun to be used: zeolites, travertines, sapropels, bentonites, etc. The prlackblem of the widespread use of natural minerals in the diet of farm animals and poultry represents a pressing issue, given their distinctive properties, waste-free technology, environmental friendliness, and relatively low cost. One of these minerals suitable for use in poultry nutrition is vermiculite (hydromica, hydrous silicate of magnesium and iron of variable composition). The purpose of the study is to determine the physicochemical composition of vermiculite from the Kulantau deposit, and its use as a mineral in the production of animal feed and development of compound feed recipes for broiler chickens Cobb500. The physicochemical parameters of vermiculite, a natural mineral, have been determined. The research analyses were carried out in the research laboratory for assessing the quality and safety of food products of the Almaty Technological University. Feed recipes were developed at LLP “AGRO FIT KAPSHAGAY”. The compound feed recipes for Cobb 500 broiler chickens of 13-28 days were tested at JSC “Alel agro”, in poultry house No. 3.
