It is crucial to bring domestic animal breeds to production and to produce meat based on sectoral structure. The objective of this study was to determine the effects of age, housing condition, and feeding style on fattening performance, comfort, and carcass characteristics of the Eastern Anatolian Red (EAR) bulls, a native breed which is suitable for adverse environmental conditions and marginal land as well as resistant to diseases. Twenty-five purebred EAR bulls (15 head of 2-year-olds and 10 head of 1-year-olds) were assigned randomly to 1 of 5 finishing programs after allocating by the age, feeding protocol, and environmental conditions. The groups were housed either individually in pens inside the barn or in paddocks outside the barn during the experimental period. The floor of the roofed paddock was cleaned and kept dry. The results indicated that there were statistically significant differences in daily live weight gain, total live weight gain (P < 0.05), and feed efficiency (P < 0.01) among the groups. The differences among the groups were also significant in terms of hot carcass, dressing, and pelvic fat (P < 0.01), as well as weights of noncarcass components (except head) (P < 0.01). The different values of the Wind Chill Index did not affect animal comfort adversely. It was clearly concluded that the EAR cattle can be a good fattening material if housing conditions and feeding style are appropriately designed.
