Teak is more considered as a major constituent in many of the traditional medicines. The proximate and phytochemical analysis of Tectona grandis leaf meal were carried out by adding it as an additives or supplements in the feed fed to broiler chickens. The fresh leaves were sliced and air-dried for 10 days and milled into fine particles. The prepared sample was kept in air tight polythene bags to prevent exposure to air, the leaves were subjected to proximate and phytochemical analysis. Data showed that the leaves had low moisture 4.57±0.40%, high carbohydrates 40.30±1.07%, protein, fibre, fat and ash of 13.28±0.28%, 28.29±0.52%, 2.17±0.28%, 11.4±0.40%, respectively. The leaf samples of Tectona grandis were screened quantitatively. Results revealed the presence of flavonoid, saponin, phenol, alkaloids and tannins. Saponin, phenol and tannin were present in large amount with 55.55±20.83mg/g, 44.87±4.41mg/g and 10.50±0.56mg/g, respectively which are responsible for its antioxidant and antimicrobial. It is completely clear from the proximate analysis that Tectona grandis leaf meal can be used as alternative medicine and animal growth promoters.
