A study was conducted to evaluate the effect of garlic supplement on the growth performance of Tau Vang chicken in the period of 7-14week old period. It was a completely randomized design with 5 treatments corresponding to 5 diets and 4 replications with 10 birds per experimental unit. The treatments were the different garlic supplement levels of 0,0.05, 0.1, 0.15 and 0.2% (in DM) to basal diet, corresponding to the G0, G0.05, G0.1, G0.15 and G0.2 treatments. The results showed that the daily intakes of DM, OM, CP, EE and ME were significantly higher (P<0.05) in the 3 last treatments (the G0.1, G0.15 and G0.2 treatments) compared with G0 treatment. The significantly higher daily weight gain, final live weight and the lower FCR were found for the G0.15 treatment (P<0.05). The garlic supplement in the diets of Tau Vang chicken improved the carcass, breast meat and thigh meat weights (P<0.05). It was concluded that garlic supplement at level of 0.15% (DM) in the diets gave higher growth performance and carcass values of growing Tau Vang chicken.
