Today more than 20 deposits of natural zeolites have been developed in Russia. There are also large deposits in the Far East. Despite the fact that Far Eastern scientists have already developed optimal norms for the inclusion of local zeolites in animal and bird diets, there are practically no publications in the open press on the comparative effect analysis of the optimal zeolite doses of different deposits on the metabolism and productivity of hens. In order to study this issue, the scientific, economic and physiological experiments were conducted in the conditions of LLC “Krasnaya Zvezda”. The effect of zeolites of different deposits was tested on similar groups by the hen dietary inclusion of zeolite in the amount of 5 % of the diet dry matter. After analyzing the obtained results, we can state that the dietary zeolite inclusion in the amount of 5 % of feed dry matter has a positive metabolism effect in the poultry body and increases the nutrient digestibility. Due to this, the poultry productivity increases: egg production increases and the commercial quality of the obtained products improves, the shell thickness increases and the egg breakage percentage decreases. The comparative analysis of the influence degree of zeolites of different deposits (Vanginskoye, Innokentievskoye, Khongurinskoye) on metabolism, productivity and quality of the obtained products did not reveal significant differences. In the conditions of poultry farms of the Amur region, the zeolites of the Wanginsky, Innokentievsky and Khongurinsky deposits in the amount of 5 % of the diet dry matter can be used with equal success. This will improve metabolism and increase egg production by 9–10 % without reducing the quality of marketable products.
