The Effect of Urea and Niacin Addition in the Mixed Feed With Dried Sugar Beet Pulp and Tapioka on Degradability of Certain Food Matter in the Rumen

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 degradation of dry matter (DM) and crude protein (CP) in rumen. Rumen fistulated four Akkaraman rams were fed ad libitum according to 4×4 latin suquare 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). Daily average feed comsumption was found as 1432.2, 1439.7.1520.4and 1347.8 g. for feed groups of the exeriment II. respectively (p<0.0). Degradations by naylon bag method of the same feeds in rumen in 48 hours were found as 77.20, 75.63. 78.63. 78.57 and 79.40 % for DM and 81.70%, 61.80. 69.41 and 84.80 % for CP for C. T, T+Ni and T+Ni+U mixed feeds, respectively (p<0.01).
