There is a positive experience in the effective co-feeding of multienzyme compositions (MEC) and probiotics in compound feeds for meat chickens based on wheat and barley grain. The objective of the research is to study the effectiveness of supplementation of probiotic Bifidum SHG and enzyme preparations (Protosubtilin G3x and Celloviridin G20x) in complete feed based on the cereal grain (maize+ barley) and sunflower oil cake of local production for enhancement of the digestibility and availability of nutrients in diets for broiler chickens. In the course of three experiments, probiotic Bifidumbacterin and enzyme preparations of Protosubtilin G3x and Celloviridin G20x were introduced into the rations of meat poultry based on maize, barley and sunflower oil cake, both individually and in various combinations. According to the generally accepted method, three physiological metabolism trials have been conducted to study the digestibility and availability of nutrients of the rations. The obtained results were processed by the method of variation statistics using the Microsoft Excel software package for mathematical analysis. During the metabolism trials, it was found that hydrolysis of complex feed polymers occurred more efficiently in the gastrointestinal tract of the 4th experimental group of chickens, which compound feed was enriched with multienzyme complex (MEC): Celloviridin G20x + Protosubtilin G3x and probiotic. Therefore, against the control, the poultry of this group showed significantly (P> 0.95) higher dry matter digestibility factors by 3.80%, organic matter - by 3.80%, protein - by 4.20%, and fiber - by 3, 10% and BEV - by 4.20%. According to the results of the III physiological experiment, with the enrichment of rations with a mixture of MEC: Celloviridin G20x + Protosubtilin G3x and probiotics, the broilers of the 4th experimental group showed the best absorption of the dietary protein against the control analogues. Keywords: broiler chickens, enzyme preparations, probiotic, compound feeds, digestibility and availability of nutrients.
