The study was carried out on 456 one-day old BUT-9 torn poults divided into 4 groups (3 replicates x 38 poults per group) fattened until the age of 154 days. The control group was fed a wheat-maize feed. These cereals were replaced by triticale and barley in the experimental diets. Mixture 1 was given without enzymatic supplements, feeds 2 and 3 contained different enzyme preparations. Less soya oil was added to enzyme-supplemented feeds, on the assumption that the addition of enzymes can increase the AMEN of triticale and wheat by 6%, of barley by 10%. Body weight and feed utilization indexes, nutrient digestibility and dressing percentage were similar in all of the groups. Enzyme-supplemented feeds were more economical in comparison with the control triticale-barley diets (by 5.0-7.5%) and wheat-maize diets (by 8.5-11.0%).
