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 ruminantsEnglishVeterinary ScienceAnimal NutritionArticle
