The aim of the study was to investigate the influence of mixtures with dehulled yellow lupin seeds and dehulled rape "00" seeds on the performance and some haematological and biochemical indexes of the blood in broiler chickens. The research was carried out on 96 Astra B broiler chickens during the period from the 1st to 49th day of life. The chickens were divided into 4 groups with 24 birds in each group. Group I - the control - was fed on a typical mixed wheat-soybean feed. Dehulled yellow lupin seeds and dehulled rape ''00'' seeds were used in the experimental diets. In groups III and IV soybean meal protein was replaced by lupin meal protein in quantities of 50% in starter feed and 100% in grower feed. Dehulled rape "00" seeds were added in a quantity of 10% to the diet for groups II and IV. The following were measured: indexes of rearing - body weight, feed and total protein consumption; haematological parameters - erythrocytes, leucocytes, Ht, MCV, MCHC, MCH and biochemical parameters - total protein and uric acid in blood plasma. Chickens fed on the diet with the parallel addition of dehulled yellow lupin and rape "00" seeds had the highest body weight (2.172 kg) and the lowest feed and protein intake (1.989 kg/kg and 0.385 kg/kg) per body gain. Rearing results obtained in the other experimental groups were comparable with controls. An influence of experimental feeding on haematological indexes was not demonstrated. In the respective groups the content of uric acid and total protein in blood plasma were within the limits of physiological standards. The obtained results indicate that dehulled lupin seeds and dehulled rape "00" seeds are useful for feeding of broiler chickens.
