The effect of enzyme supplementation of triticale-barley feeds on fattening performance of turkeys

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%).
