Abstract: Four Nubian male goats were used in Latin square design to study the effects of untreated baggase supplemented with 150 g of Albizia lebbeck (US), 3% ammonia treated bagasse (T) and the treated bagasse supplemented with 100 g of Albizia lebbeck (TS1) or 150 g of Albizia lebbeck (TS2). Parameters measured were dry matter and crude protein intake, dry matter, crude protein and neutral detergent fiber digestibility and rumen fermentation. The results showed that the feed intake and dry matter, crude protein and neutral detergent fiber digestibility were significantly (p<0.05) higher for TS1 and TS2 than US or T. TS1 and TS2 gave the highest value of VFA, NH3N concentration and lower pH value than T or US.
