[Objective] To study the effect of black tea extract on pork quality and biochemical indicators.[Method] 60 DLY pigs weighed about 50 kg were selected and divided randomly into control group and experimental group.The control group was fed by basal diet,and the experimental group was fed by basal diet plus 2 g/kg black tea extract.Each indicators of the pork were detected when the pigs grew into 100 kg`s weight.[Result] Slaughter performance of pigs in experimental group was improved,the slaughter rate increased significantly(P0.05);The pork quality was improved significantly,pork color improved(P0.05),muscle abundance increased significantly(P0.01);Biochemical Indicators were improved,IMP increased significantly(P0.05),cholesterol decreased significantly(P0.05),iron and zinc content increased significantly(P0.05).[Conclusion] Diet added 2 g/kg black tea extract could improve pork quality.
