摘要

Objective: The aim of this study was to determine the effect of cadmium (Cd) on the level of phospho-lipids peroxidation, by measuring the level of malondialdehyde (MDA) and study the changes on body weight of egg-laying breed chickens. Methodology: Total four groups of chickens have been included in the experiment. Three groups treated with different concentrations of cadmium (2, 4 and 6 mg kg?1 of live weight added in drinking water) and one group as a control without treatment with Cd. The data were analyzed statistically by using SPSS software package. ANOVA test and the medium and standard error of the mean were presented. Results: The result shows that, level of malondialdehyde in blood is increased by increasing the cadmium on daily diet of chicken. On the control group, the MDA level was 17 μmol L?1 when we have treat with cadmium 2 mg kg?1 the level increase amounts twice (30 μmol L?1), on the 3rd group 44 μmol L?1 when was supplemented with 4 mg kg?1, while on the 4th group (supplemented with 6 mg kg?1 Cd) it reach up to 64 μmol L?1. In another hand, body weight of egg-layer chicken in three different times point, supplemented with different amount of Cd shows to be different. When the chickens was not treated with Cd body weight on last days reach up to 1114 g while by adding the Cd on feed the body weight has decrease to 734 g. Conclusion: It can be concluded that, MDA is increase by increasing the cadmium concentration on daily diet. This is due to makes difficulties on peroxidation of the lipids or proteins on body chickens and also plays negative effects on increasing the body weights. Also the body weight of the egg-laying breed chickens was decreased by feeding the chicken with Cd indicating that Cd plays a negative effect on feeds and most probably on the quality of the meat.
