Copper (Cu), Zinc (Zn), Iron (Fe) and Manganese (Mn) levels in drinking water,
layer feed and muscle samples were collected during winter season from two layer
farms which present at two different areas, non industrial area (Integrated poultry
project in El-Azab) and industrial area (Kom Oshim) in Tamia district in ElFayoum province, Egypt. All samples will be analyzed to determine the
translocations of heavy metals from water and feed to the bird's muscle. The
results explained that the mean metal concentrations in the different samples of
selected poultry farms are Pb (1.1034±0.097, 1.173±0.129), (2.891±0.194,
3.182±0.28) and (0.071±0.03, 0.099±0.0396 ppm). Cd (0.419±0.004,
0.389±0.017), (0.508±0.017, 0.5854±0.003) and (0.005±0.0013, 0.0125±0.003
ppm). Cu (5.9±2.1, 0.8596±0.054), (9.15±1.202, 14.75±0.417) and
(0.0442±0.0075, 0.03032±0.004 ppm). Zn (14.50±1.285, 13.628±1.053),
(57.605±3.06, 58.319±0.73) and (0.0668±0.018, 0.016±0.00498 ppm). Fe
(171.011±79.6, 186.74±72.65), (153.58±15.3, 124.12±3.26) and (0.013±0.008
ppm, ND). And Mn (3.187±1.539, 1.398±0.768), (84.98±5.676, 85.884±1.07) and
(0.0056±0.0037ppm, ND) for muscle, layer feeds and drinking water which were
collected from non industrial area and industrial area in El-Fayoum province,
Egypt, respectively. These data indicated that Pb and Cd in muscle, layer feeds
and drinking water collected from industrial area were higher than that collected
from non industrial area. Also these metals residual concentrations particularly in
layer muscle and drinking water were more than the permissible limits.
