The present study was conducted to evaluate the effect of Sauropus androgynus extract (SAE) and lemuru oil (LO) on fat deposition and fatty acid composition of meat in broiler chickens. One hundred and fifty six broiler chickens were distributed to 13 treatment groups with 3 cages in each treatment group as replicate. Completely randomized design was used in this study. The thirteen groups were as follows: 1) Broiler chickens were fed diet contained commercial feed supplement as a control; 2) Broiler chickens were fed diet contained 10 g/kg diet SAE and 1% LO; 3) Broiler chickens were fed diet contained 10 g/kg diet SAE and 1% LO plus 60 mg vitamin E; 4) Broiler chickens were fed diet contained 10 g/kg diet SAE and 2% LO; 5) Broiler chickens were fed diet contained 10 g/kg diet SAE and 2% LO plus 60 mg vitamin E; 6) Broiler chickens were fed diet contained 10 g/kg diet SAE and 3% LO; 7) Broiler chickens were fed diet contained 10 g/kg diet SAE and 3% LO plus 60 mg vitamin E; 8) Broiler chickens were fed diet contained 18 g/kg diet SAE and 1% LO; 9) Broiler chickens were fed diet contained 18 g/kg diet SAE and 1% LO plus 60 mg vitamin E; 10 Broiler chickens were fed diet contained 18 g/kg diet SAE and 2% LO; 11) Broiler chickens were fed diet contained 18 g/kg diet SAE and 2% LO plus 60 mg vitamin E; 12) Broiler chickens were fed diet contained 18 g/kg diet SAE and 3% LO; 13) Broiler chickens were fed diet contained 18 g/kg diet SAE and 3% LO plus 60 mg vitamin E. The data were analyzed by variance analysis and if it were significant, it were tested by DMRT.The present results showed that supplementation of SAE and LO significantly affected fat deposition in abdomen and leg (P<0.05), but it had no effect on neck fat deposition and fatty acid syndrome. The present results showed that supplementation of SAE and LO had significantly reduced cholesterol content (P<0.05) and TBA (P<0.05) in leg meat, but it significantly increased vitamin A and vitamin E (P<0.05) and it had no effect on fat in leg meat. Supplementation of SAE and LO was proved to change fatty acid composition in leg meat. The treatment significantly increased EPA, DHA (P<0.01), arachidonic acid and stearic acid (P<0.05), but it significantly reduced linolenic acid (P<0.05). In conclusion, the supplementation of SAE and LO reduced fat deposition in abdomen and leg, the content of cholesterol in meat, and it enriched EPA and DHA of meat.
