HOŠKOVÁ, Š., VAŠÁTKOVÁ, A., KRATOCHVÍLOVÁ, P., BALABÁNOVÁ, M., LICHOVNÍKOVÁ, M., ZEMAN, L.: The infl uence of distillers dried grains with solubles in broiler's feed mixtures on their growth parameters. Acta univ. agric. et silvic. Mendel. Brun., 2010, LVIII, No. 5, pp. 179-184 The eff ect 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 12 th , 26 th and 35 th day of age. Control group of cockerels (0 % DDGS) had the highest fi nal live weight and its average daily weight gain was signifi cantly 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 signifi cantly diff erences in feed consumption per bird and in feed conversion between groups. The results show that incorporation from 10 to 25 % DDGS decreased fi nal weights and weight gains however there were no signifi cantly diff erences in feed consumption and feed conversion.
