In vitro Rumen Degradability Study of Wet Brewer’s Spent Grain by Modified Rumen Simulation Technique (TANUVAS-RUSITECTM)

Abstract
Wet brewer‟s spent grain (WBSG) is the extracted residue remaining after grains have been fermented during beer making process. The annual WBSG production in India is approximately 0.4 million tones and can serve as a good feed ingredient for livestock especially for ruminants as it is a good source of protein with a crude protein content ranging from 25 to 34 per cent and has 7 to 10 per cent crude fat. In vitro dry matter and nitrogen degradability of wet brewer‟s spent grain were determined using a modified rumen simulation technique (TANUVAS-RUSITECTM). The effective DM and nitrogen degradability of WBSG were 40.72 and 33.40 per cent, respectively. The rumen degradable protein (RDP) was 32.72 per cent and rumen undegradable protein (RUP) was 54.93 per cent. Wet brewer‟s spent grain containing 27.47 per cent crude protein with 54.93 per cent rumen undegradable protein (RUP) can be effectively used as a potential bypass protein source in the ruminant diet.
