Four hundred and eighty 1-day-old Arbor Acres chicks were randomly assigned to 5 treatment groups consisting of 8 replicates of 12 birds to study the effects of wall-breaking technology of green tea on meat quality and the residual of heavy metal of broiler. The birds were fed with basal diet supplemented with 0 (control group), 100、200、400 and 800 mg/kg wall-breaking green tea (0、10、20、40、80 mg/kg tea polyphenols). Result showed: (1) The supplement of wall-breaking technology of green tea in diet increased the pH value of breast, decreased dripping loss content of breast(P>0.05), the MDA content of breast decreased by 5.88%、5.88%、0.59%、11.76%(P>0.05), respectively. The vitamin E content of breast increased by 63.01%、0.34%、95.54%、3.08%, the vitamin E content of liver increased by 3.37%、55.03%、44.53% at 20、40、80 mg/kg treatments(P>0.05). (2) The broilers fed with wall-breaking green tea reduced the residual of lead and cadmium in liver of broilers, but all treatments had no significant effect on lead and cadmium content of broiler breast.
