The percent dry matter, organic matter, crude protein, ether extract, crude fibre, total ash, nitrogen free extract and acid insoluble ash of dried tomato pomace (DTP) were 89.56, 90.99, 22.39, 12.23, 40.1, 9.01, 16.27 and 3.63, respectively. The calcium and phosphorus content of the DTP was 0.56% and 0.48%, respectively. The tannin content of DTP was 2.09%. The percent neutral detergent fibre, acid detergent fibre, hemicellulose, cellulose, permanganate lignin and silica content of DTP were 66.5, 60.0, 6.5, 43.38, 13.1 and 3.52, respectively. The starch and soluble sugars content of DTP were estimated as 10.17% and 1.02%, respectively. Metabolizable energy content of DTP was calculated as 2172 kcal/kg. The true metabolizable energy content of DTP as estimated using adult cockerels was 2193 kcal/kg and the apparent metabolizable energy content was 2080 kcal/kg. The N utilization of DTP was 56.64%. The high protein and ME content of the DTP revealed that tomato pomace can be a potential feed ingredient for poultry.


Key words
