Abstract. The article provides the results of the studies on the efficiency of using dry apple pomaces with and without chelate copper and zinc addition in diet of breeding geese. The experiment demonstrated the effective level of these additives and their influence on the morphological qualities of eggs and on the level of productivity was examined. It is found that the usage of non-traditional feed additives improves the process of egg laying, and increases hatchability and vitality of goslings. Thus, it is obvious that inexpensive, practically dry apple pomaces can significantly increase the income of a poultry farm. Besides, it was shown that the highest level of hatchability and survival was present at a content of 7% of dry apple pomaces, enriched with chelate copper and zinc forage supplementation. This implies that such feed additives meet the high physiological needs – not only in nutrients, but also in biologically active matter, which satisfy the needs of the organism and provide appropriate level of realization of the genetic potential of breeding geese performance, especially promote more intensive usage of substrates for synthesis of the main components of the eggs.
