Two experiments with LSL- and LB-chicks and pullets were carried out to investigate the effect of 5, 10, 15 and 20 % distiller's dried grains with solubles in a wheat based diet. The growth performances and the dry mat- ter concentration of the excrements did not differ among the groups up to a distiller's dried grains content of 20 % of the diet. However, the supplementation of the enzyme ZY 68 slightly improved the zootechnical parameters, and the enzyme Kemzyme W significantly improved the body weight and the feed efficiency. The different nutrition without and with 15 % distiller's dried grains in the raising period did not effect the following laying period. 20 % distiller's dried grains with solubles may be included in a wheat based diet in extensive growing chicks and pullets The effect of 5, 10, 15 arid 20 % distiller's dried grains with solubles in a wheat based diet of two origins was investigated in starter and fattening feed of Cobb broilers in the three experiments. The fattening performance was diminished with increasing content of distiller's dried grains with solubles. Due to the result,s a maximum content of 5 % distiller's dried grains with solubles in a wheat basis can be recommended in intensive growing broilers. No significant effects on feed conversion, egg production and egg quality were detected in two experiments with laying hens receiving up to 25 % distiller's dried grains with solubles in their diets. However, more than 15 % of the diet tended to decrease the produced egg weight and to impair the feed efficiency. When the diet containing 15 % distiller's dried grains with solubles was supplemented with NSP hydrolysing enzymes the egg production was improved by 1,4 %, the feed efficiency by 1,2 % and the live weight gain by 97 g. A distiller's dried grains with solubles content of 15 % in the diet of laying hens are possible.
