Estimation of some heavy metals concentration in layer farms at El-Fayoum Governorate

Abstract EN

The objective of this work was to estimate the lead (Pb), Cadmium (Cd), 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
