Study the Effects of Heavy Metals (Lead and Cadmium) on Some Biochemicalparameters of Dairy Cattle in Baghdad Province

Abstract

This study investigatesthe effects of heavy metals (Lead and Cadmium) on some biochemical parameters
of dairy cattle in Baghdad province(Taji, Abu Ghraib, Al-Fudilia, Letifia and Youssoufia)regions.Thirty
samples of blood from dairy cattle in five different regions were taken to measure the Lead and Cadmium
concentration by atomic absorptionwhile serum were collected for measuring, liver enzymes (aspartate
aminotransferase AST and alanine aminotransferase ALT) activity,Serum total protein, serum albumin,
serum globulin and serum creatinineconcentration.The results showed a significant increase (p< 0.05) in the
leadand cadmium ion concentration in the blood sample of the dairy cowsin Youssoufia region compared
with other region. On the other hand, the total protein and globulin concentration of the dairy cattle in Abu
Ghraib region recorded significantly (p < 0.05) higher value compared with Letifia region. While Albumin
and creatinine concentrations showed non-significant (p > 0.05) differences among the different regions.
Liver enzyme AST concentration showed significant increase (p < 0.05) in the serumof dairy cows in Letifia
and Youssoufia regions. However, serum ALT were increased significantly(p < 0.05) in Letifia than Abu
Ghraib region.Concluded from thisstudythatdairy cattle inLetifia and Youssoufia regions were subjected to
pollution with heavy metals which caused Increased heavy metal content in the blood of cattle and affect
their health by increased the concentration of liver enzyme and reduction of total protein in the blood of
dairy cattle compared with other region in Baghdad province.
