Abstract
Aim of the present study was to evaluate the feeding value of spent coffee waste in ruminants. Nutrient
composition of spent coffee waste (SCW) revealed that it contains Crude protein, Ether extract, Crude
fibre and Nitrogen free extract at 12.02%, 9.23%, 56.20% and 21.73% respectively. SCW had higher
neutral detergent fibre, acid detergent fibre and Lignin content of 79.67, 68.54 and 34.08% respectively
when compared with conventional feeds and also contained high amount of Acid detergent insoluble
protein (67.54%). Total phenol content in SCW was 0.35%. In vitro gas production studies revealed that
SCW has significantly (P<0.01) lower gas production potential (2.13 ml), in vitro true dry matter
digestibility (17.48%) and ammonia nitrogen (1.75 mg/100ml) content when compared with conventional
feeds like maize. It can be concluded that spent coffee waste as such has less potential as a concentrate
feed source in ruminants
