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.
