This research was conducted to investigate the effects of housing types three side open with no shelter, one side open with shelter and closed barn and the seasons of fattening winter and summer on the fattening performance and slaughter characteristics of 8-8.5 month-old Bleck and White bulls in Field Crops Central Research Institute, Ankara. The animals were fed 1 kg straw and 2 kg concentrates daily in addition to ad libitum barley during the 24 weeks of fattening period. During the fattening period; total weight gain, daily gain, ary matter intakes barley + straw + concentrate for one kg live weight gain were found as 209 kg, 1243 g, 6.75 kg winter group, 204 kg, 1213 g, 6.79 kg in summer group, 191 kg, 1138 g, 7.36 kg in the group housed in three side open with no shelter barn, 216 kg, 1286 g, 6.42 kg in the group housed in one side open with shelter barn, 212 kg, 1260 g, 6.53 kg in the group housed in closed barn, respectively. The averages dressing percentage from cold carcass weight and pelvic fat were calculated as 57.1 % and 4.68 kg in winter group, 56.8 %, and 3.68 kg in summer group, 56.6 % and 3.52 kg in the group housed in three side open with no shelter barrı , 57.1 % and 4.18 kg in the group housed in one side open with shelter barn, 56.8 % and 4.63 kg in the group housed in closed barn, respectively.
