In adverse dry weather conditions the yield of traditional crops is sharply reduced, particularly of maize, therefore it is required a drought-resistant crop with high forage characteristics. This crop is the grain sorghum. The presence of non-starch polysaccharides in sorghum grain creates the preconditions for the inclusion of enzyme preparations in the combined feed for broiler chickens. The aim of the study was to provide high productivity of the broilers fed the combined feed, containing up to 30% of grain sorghum with the additional use of the enzyme preparation "CelloLux -F". Positive results are achieved both in productivity and digestibility of the main nutrients in the combined feed with the enzyme. It is recommended to include the enzyme into combined feed for broiler chickens at the amount of 100g/t of feed. Application of enzymatic agent "CelloLux -F" as a component of combined feeds for broiler chicks favors live weight gain, feed conversion efficiency and safety of young birds. It is recommended to include the enzyme into combined feed for broiler chickens at the amount of 100g/t of feed
