Growth performance and carcass characteristics evaluation of two years old Kereyu bulls fed on three dietary feed rations was conducted at Adami Tulu Agricultural Research Center during the year of 2014. The objectives of the study were to evaluate the growth performance and carcass characteristics and to identify the most economical feeding rations for export/local market weight gain. Eight experimental bulls were assigned to each of the three dietary treatment groups (T1=Rhodes grass hay ad-lib, molasses 20%, wheat bran 35% and linseed cake 45%, T2= Rhodes grass hay ad-lib, maize grain 20%, wheat bran 45% and Noug cake 35%, T3= G Rhodes grass hay ad-lib, wheat bran 65% and cotton seed cake 35%) in a Randomized complete block design. All the experimental bulls were supplemented with their respective feed rations at 2.5% of their body weight per day during the whole experimental periods. Finally, after 18 hours fasting, 3 bulls from each treatment group were randomly selected and slaughtered for carcass analysis. Data on feed intake, live body weight change, feeds conversion efficiency and carcass parameters were analyzed using general linear model (GLM) of Statistical Analysis System (SAS) version 9.2. Results of the fattening trial revealed that there is no significant difference in daily weight gain, total weight gain, final body weight, feeds conversion ratios and carcass characteristic of bulls fed on treatments 1,  2 and  3 at 168 fattening days (P>0.05). But there was significant difference in feed conversion efficiency and dry mater intake of bulls fed on T1 and T3 (P< 0.05). Even though all the three feeding rations are economically profitable, feeding of bulls with T1 is more profitable as compare to T 2 and T3. Therefore beef cattle fatteners can use T1 for fattening of two years old Kerayu bulls for export/local market weight gain and for better economic return.
