Female adult chickens were used to study the effects of cadmium on the serum sex hormone levels.180 Hy-line white hens in the age of 50 days were divided into 3 groups,60 in each group.The hens were fed with complete feed administered with 0 mg/kg CdCl2,140 mg/kg CdCl2 and 210 mg/kg CdCl2 respectively to establish cadmium poisoning models.Gathering blood by intracardiac penetration at the 20th,40th,and the 60th days,serum were collected for detecting serum progesterone and estradiol.Body weight and ovary weight were measured.The results showed that growth performance,development of ovaries were inhibited by cadmium,serum E2 and P4 decreased after adding cadmium,and there was an obvious time-dose effect relation.
