Chickens, fattened for 56 days, were treated with nitrovin at the dose of 15 mg per kg of feed, cyadox at the dose of 20 mg per kg of feed, and virginiamycin at the dose of 10 mg per kg of feed. After the fattening, the chickens were studied for the contents of copper, zinc, and manganese in the blood serum, thigh muscle, breast muscle, and feathers. The contents of copper, zinc and manganese in the serum ranged within the limits of physiological values. As for the breast muscle, the content of copper increased but the content of manganese declined in both breast and thigh muscle, as compared with the control group. The feathers contained more manganese in all the groups, as compared with the controls.
对育肥56天的鸡，分别用每千克饲料含15毫克的硝呋烯腙、每千克饲料含20毫克的喹乙醇以及每千克饲料含10毫克的维吉尼亚霉素进行处理。育肥期结束后，对鸡的血清、大腿肌肉、胸肌和羽毛中的铜、锌和锰含量进行了研究。血清中铜、锌和锰的含量在生理值范围内。与对照组相比，胸肌中铜含量增加，胸肌和大腿肌肉中锰含量均下降。与对照组相比，所有组的羽毛中锰含量更高。
