Broiler Carcass Contamination Elsaid Eman

Feed withdrawal refers to the total length of time the chickens are without feed prior to processing which reduce carcass contamination. Generally, research investigates the effect of different pre-slaughter feed withdrawal periods (0.0, 4.0, 8.0 and 12.0 h) and live body weight grade at slaughter (grade W1 from 1800 to 2000 g and grade W2 from 1600 to 1800 g) on carcass contamination. In addition the effect of carcass immersion in acetic acid (10%) for 15 minutes and different pre-slaughter feed withdrawal periods (0.0, 4.0, 8.0 and 12.0 h) on microbiological structure of gut content total microbial counting of some broiler parts, microscopical examination of the viable bacterial total count and Pathogenic bacterial counting of some broiler parts were also tested.
