This study was undertaken to investigate the effects of feed withdrawal time(FWT) before transport in farm(<2 hrs, 2~4 hrs, 4~6 hrs) and total feed withdrawal time(TFWT) before slaughter(<8 hrs, 8~12 hrs, >12 hrs) on carcass defects, grades and meat quality of broilers. FWT of 2~4 hrs before transport in the farm showed lower incidences of dead-on-arrival chicks(p<0.05) and bruising chicks, and a little higher incidences of 1st or 2nd carcass grade compared to shorter than 2 hrs or 4~6 hrs of FWT in the farm. In the meat quality of breast meat, FWT of 2~4 hrs in the farm tended to show higher pH and water holding capacity(WHC), and lower drip loss, cooking loss and shear force values compared to shorter than 2 hrs or 4~6 hrs of FWT in the farm. In the total microbial counts of breast meat during 7 days of cooler storage, FWT of 2~4 hrs in the farm showed significantly lower value than shorter than 2 hrs of FWT in the farm. In the carcass defects and grades by TFWT before slaughter, TFWT shorter than 8hrs showed lower(p<0.05) incidences of dead-on-arrival chicks and bruising chicks, and higher(p<0.05) incidences of 1st carcass grade than TFWT longer than 12 hrs before slaughter. In the meat quality of broiler breast meat, TFWT longer than 12hrs before slaughter showed lower(p<0.05) pH and WHC values, and a little higher drip loss, cooking loss and shear force values compared to TFWT shorter than 8 hrs or 8~12 hrs before slaughter. In the total microbial counts of broiler breast meat during 7 days of cooler storage, TFWT longer than 12 hrs before slaughter tended to show higher value than TFWT shorter than 8 hrs or 8~12 hrs before slaughter. As a result, 2~4 hrs of feed withdrawal time before transport in the farm and total feed withdrawal time shorter than 8hrs or 8~12hrs before slaughter could be recommended for the production of high quality broiler meat.
