Abstract: To study the effects of flavones of sea buckthorn on carcass characteristics and meat quality of AA broilers， a total of 360 1-day-old health male Arbor Acre broilers were randomly used for 3 dietary treatment. Each treatment was replicated four times with thirty broilers each. The three dietary treatments were basal diet，basal diet+0.1% flavones of sea buckthorn and basal diet+0.2% flavones of sea buckthorn. Apparent digestibility of nutrients (crude protein， ether extract， calcium， phosphorus)， carcass characteristics， meat quality and some blood biochemical index were determined. The results showed that apparent digestibility of dietary protein inclined to increase (P=0.054)， apparent digestibility of dietary calcium was significantly increased (P<0.01)， diameter of thigh muscle fiber tended to decrease (P=0.080) at the dose of 0.1% flavones of sea buckthorn. At the dose of 0.2% flavones of sea buckthorn， carcass percentage was significantly increased(P<0.01)， abdominal fat percentage was significantly reduced(P<0.01); meat color of breast and thigh muscle， crude protein of thigh muscle were significantly increased(P<0.01)， drip loss of breast and thigh muscle， ether extract of thigh muscle and serum triglyceride were significantly decreased(P<0.05). Apparent digestibility of dietary crude protein and calcium were increased by the diet supplemented with 0.1% and 0.2% flavones of sea buckthorn， and carcass characteristics and meat quality were improved by the diet supplemented with flavones of sea buckthorn. Moreover， flavones of sea buckthorn were nontoxic and harmless.
