Abstract
Eighty-12 weeks old Gimmizah chicken were used to study the effect of diets contaminated with combination of lead acetate [Pb] and aluminum sulphate [Al] at levels [200 ppm Pb+200 ppm Al [T2], 300 ppm Pb+300 ppm Al [T3], 400 ppm Pb+400 ppm Al [T4]. A group of birds fed diet without any supplementation was used as a control group [T1]. Levels of Pb and Al were added to corn-soy diets and fed to birds from 12 to 19 wk of age. Feeding level T3 decreased significantly [P<0.01] body weight gain of birds by about 43% than control birds followed by level T4. Percentage of protein and moisture of breast and thigh tissues were not affected by any level of contamination. In contrast, all levels of contamination to the diet increased fat percentage of thigh tissues as compared to control tissues. Residues of Pb and Al in all studied tissues became significantly higher than control one. A great leap occurred in the tissues residues of Pb and Al at level T2. The highest concentration of Pb was obtained in the tissues of liver and brain [32.5 and 28.0 ppm Pb, respectively], and the highest concentration of Al was recorded in the tissues of liver and bone [19.9 and 28.4 ppm Al, respectively]. The meat had the lowest concentrations of Pb or Al. Cooking resulted in slight reductions in Pb and Al concentrations, it did not exceed than 1.7 ppm for all tissues.
