The studies were designed to determine an effect of partial replacement of soybean meal with rape cake supplemented with enzymes on the nutritional value of diets and the number of lactic acid bacteria (LAB) in the ileum and caecum of broilers. The experiment 1 (growth trial) was carried out on 120 one-day-old broiler chickens Ross 308 which were randomly divided into four homogenous groups, 30 birds per group (15 males and 15 females). Each treatment consisted of six replicates of 15 birds. A control diet contained soybean meal whereas in the experimental, a part of the soybean meal was replaced by 15% rape cake from the Kaszub cultivar and supplemented with enzyme preparations containing xylanase or phytase added individually or in combination. The experiment 2 (digestibility trial) was carried out on 60 seven-day-old chickens divided into four treatments of 20 birds (4 replicates of 5 birds) to determine nutrient digestibility of diets used in the growth trial. The digestibility test was carried out by the total collection method.
