 Abstract. The aim of this study was to evaluate the effect of including cavitated wheat bran in the diet on the productivity and blood biochemistry of broiler chickens. The object of the study: broiler chickens of the Ross 308 cross (n=40). Until two weeks of age, the birds were in the preparatory period and received the basic diet (BD). Starting from the age of 15 days, the birds of experimental groups I, II and III received BD with 3%, 6% and 9% of the grain portion replaced by cavitated wheat bran, respectively. The duration of the accounting period was 28 days. The results of the study indicate the feasibility of including 6% cavitated wheat bran in the broiler diet. The effectiveness of the use is confirmed by maintaining high rates of live weight growth, optimization of feed costs and a pronounced hypocholesterolemic effect, which is manifested in a reliable decrease in blood cholesterol levels by 35% (p=0.002). On the contrary, an increase in bran content to 9% was accompanied by a decrease in growth rates (by 9%, p=0.04), an increase in feed costs and metabolic shifts, manifested in a decrease in the level of total protein (by 10%, p=0.02) and an increase in AST activity (by 66%, p=0.002).

Keywords: broiler chickens, wheat bran, fiber, dietary fiber, cavitation, productivity, metabolism
