The purpose of this work is to review the work in the field of optimization of animal feeding in the conditions of the Republic of Sakha (Yakutia). Some results of the scientific and educational-research activities of the Department of General Zootechnics in the direction of optimizing animal feeding in the RS (Y) are given. In the works of A.I. Grigoreva - the effectiveness of local non-traditional feed additives, such as local mineral, sapropel, zeolite-sapropel, salts, vitamin-mineral and others, in feeding farm animals is noted. It was found that the inclusion of non-traditional feed additives in the diet of young cattle contributed to an increase in growth rate by 12.91%. The use of experimental complex feed additives from natural raw materials in the feeding of young cattle contributed to an increase in growth rate by 6.7%. In another experiment, it was found that the inclusion of local non-traditional feed additives in the diets of goats contributed to an increase in milk yield by 13.38 and 23.57%. Therefore, the use of local non-traditional feed additives from local natural raw materials in the feeding of farm animals can increase the productivity of animals in the conditions of the Republic of Sakha (Yakutia).
