The influence of distillers dried grains with solubles in broiler s feed mixtures on their growth parameters [Vliv sušených obilných lihovarských výpalků ve směsích pro brojlery na jejich růstové parametry]

The effect of distillers dried grains with solubles (DDGS) in broiler feed mixtures on the performance was studied in an experiment with 1000 male broiler chickens Ross 308 from 12 to 35 days of age. DDGS were produced from wheat (90%) and triticale (10%). Cockerels were divided into 5 groups and were housed on deep litter. Experimental feed mixtures were formulated to contain: 0,10,15,20 and 25 % DDGS and were calculated as iso-nitrogenous. Weighing of chickens was realized at the 12th,26th and 35th day of age. Control group of cockerels (0% DDGS) had the highest final live weight and its average daily weight gain was significantly higher (P ≤ 0.01) than in birds from groups with 10,15 and 25 % DDGS. Broilers from control group (0% DDGS) had the highest consumption of dry matter of feed mixture per bird. There were no significantly differences in feed consumption per bird and in feed conversion between groups. The results show that incorporation from 10 to 25% DDGS decreased final weights and weight gains however there were no significantly differences in feed consumption and feed conversion.
