In this paper the influence of broken corn and extruded broken corn addition in broiler diet on carcass quality was investigated. The experiment was conducted on broiler hybrid ROSS (n = 720) divided in three groups. The first group (control - C) was fed with commercial broiler feed mixture, while second and third groups were fed with commercial mixtures where 25% of corn was substituted with broken corn (experimental group E1) or extruded broken corn (experimental groups E2). Broiler fattening lasted 35 days, and food and water were provided ad libitum in the floor fattening system. The obtained results indicate that the substitution of corn with broken and extruded broken corn did not affect significantly (P > 0.05) on the mass of cold carcasses. Also, shares of carcass main parts (breast, whole legs, back portion and tail end and wings) showed no significant (P > 0.05) differences between all three groups. The only significant difference (P < 0.05) was determined for mass of abdominal fat between control C (14.4 g) and experimental group E2 (21.2 g). Differences of meat yield in breast and whole leg of broilers from different groups were not registered as significant (P > 0.05). Based on the results obtained in this study it can be concluded that the use of 25% of broken or extruded broken corn in broiler diet did not have significant influence on carcass quality.
