Abstract: In this study, it was aimed to determine the effects of different energy sources feeds, which are dried sugar beet pulp (pulp) and tapioka added 2% urea and 400 mg/kg niacin on the feed consumption and degredation of dry matter (DM) and crude protein (CP)in rumen fistulated four Akkaraman rams were fed ad libitum according to 4x4 latin suguare design in this study. The first experimental mixed feed groups, consisted of control (C), pulp (P), pulp added niacin (p+Ni) and pulp added niacin and urea (P+Ni+U). The second mixed feed groups, consisted of control (C), tapioca (T), tapioca added niacin (T+Ni) and tapioca added niacin and urea (T+Ni+U). In the first experiment, daily average feed consumption was found as 1322.3, 1204.8, 1394.1 and 1478.5 g,. respectively (p<0.05). Degradations by naylon bag method of the same feeds in rumen in 48 hours were found as 77.89%, 78.35, 79.05 and 81.10% for DM matter and 82.26, 74.01, 75.01 and 91.25 % for CP for C, P, P+Ni and P+Ni+U mixed feeds, respectively (p<0.01).
