The aim of this thesis was to evaluate the effects of addition of technical hemp (Cannabis sativa L.) on performance parameters of broiler chickens. A total of 105 broilers Ross 308 were divided into three groups. The groups were identified: Cannabis 5, Cannabis 15 and Control. Group Cannabis 5 was fed with 5 % hempseed cake in feed composition. Group of Cannabis 15 was fed with 15 % hempseed cake in feed composition. Group of Control was not fed with hempseed cake. As a response criterion was chosen weight gain, feed conversion, lean meat, carcass yield and blood liver enzymes concentration. In this thesis, we focus on assessing the impact of hempseed cakes on weight gain, feed conversion and the carcass yield. The increments in body weight were significant statistical differences (P < 0.05). Broilers fed with 15 % hempseed cake in feed composition grew slowly and had worse feed conversion. Carcass yield was not affected (P > 0.05) by content of hempseed cake in feed composition. Measured concentration of enzymes in groups was not affected by contents of hempseed cake.
