Abstract: This study was aimed to compare fattening performance, slaughter characteristics of Simmental (n=20) and Black & White (n=20) young bulls under subtropical climate conditions. Animals in both breeds in (5 equal groups for each breed) were fed on a diet containing 162 g CP and 10.7 MJ ME kg-1, based on body weight criterion for 120 days. With respect to total live weight gain and daily live weight gain, Simmental young bulls were higher than Black & White young bulls (168.1 kg vs. 141.8 kg and 1.401 vs. 1.181 kg). Besides, the feed conversion ratio data show that Simmental young bulls converted feed to body mass more efficiently than that of Black & White young bulls (6.49 vs. 7.44, kg feed : kg gain). Slaughter weight and hot carcass dressing percentage in Simmental and Black & White young bulls were found out as 445.4 kg vs. 416.3 kg and 57.15 % vs. 56.04 %, respectively. These results showed that Simmental breed was more preferable than Black & White breed under subtropical climate condition with respect to fattening performance and slaughter characteristics for beef production.
