| Abstract: |
| In order to strengthen source control of heavy metal pollution from poultry farming, 180 kinds of chicken feed samples in Huanghuai-hai Region (Beijing, Tianjin, Henan, Hebei, Shandong, Jiangsu, and Anhui)were collected, and then analyzed the concentrations of Mn, Cu, Zn, Cr, Ni, Cd, Pb and As in chicken feed samples of different provinces, different culture species and different growth stages. The results showed that the amount of heavy metals varied greatly in the chicken feed in Huang-huai-hai area, the contents of Cr, Mn, Ni, Cu, Zn, As, Cd and Pb in the feed samples were 0.05~9.91, 52.59~726.68, 0.02~6.84, 12.74~458.70, 34.09~594.78, 0.01~3.98, 0.01~1.96 mg·kg-1 and 0.02~10.76 mg·kg-1, respectively. Compared with the Feeding Standards of Chicken the content of Mn, Cu, Zn in chicken feed was over rate of 99.1%, 100%, 69.0%, respectively. Compared with the Feed Hygiene Standard the content of Pb, Cd in chicken feed was over rate of 39.7%, 23.50%, respectively. There had some extend differences in feed heavy metals among different provinces. As a whole, the contents of heavy metals in Anhui Province were highest, and while it was lowest in Tianjin. The maximum detected contents of Mn, Cu and Zn in feedingstuff of laying hens were 680.86, 458.70 mg·kg-1 and 580.27 mg·kg-1, respectively, and in the feed of broilers it were 726.68,399.07 mg·kg-1 and 594.78 mg·kg-1, respectively. The average concentration of Mn, Cu and Zn was all over Feeding Standard of Chicken of China. The feed of laying period of laying hens had the highest heavy metal content, and while it was higher in the middle and late stage feed for broiler. |
