研究了经口施用镉对雉鸡生育力、雏雏体重及幼雏和成年雉鸡部分器官镉含量的影响。在3个月的时间内，以1.5mg Cd ~（2+）/L的浓度施用金属。产卵后，测定产卵数、破蛋数和未受精蛋数，并测量新孵出雏鸡的活重。镉在肝脏、肾脏和肌肉中的浓度（m.胸肌）的变化。我们发现，镉暴露的成年人并没有影响产卵的数量，但导致更多的鸡蛋被损坏。在镉摄入4周后，镉处理组的孵化幼体（21.36± 2.28 g）比对照组（20.91± 1.97 g）显著增加。高镉浓度观察到在肌肉和肾脏组织中的新孵化的野鸡4周后相比，镉暴露组后8周和12周。成年雉鸡肾脏和肝脏中镉含量显著升高。在成年雉鸡中，镉主要在肾脏中积累，在饮水中摄入镉3个月后，镉含量达到9.64mg/kg湿重。成虫肝脏中的浓度为3.53mg/kg湿重。
In this study, the effects of cadmium applied per os on fertility, live weight of newly hatched chicks, and cadmium concentrations in some organs of young and adult pheasants were investigated. The metal was applied at the concentration of 1.5mg Cd2+/L during 3 months. After the egg laying, the numbers of eggs laid, cracked, and unfertilized were determined and the live weights of newly hatched chicks were measured. The cadmium concentrations in liver, kidney, and muscle (m. pectoralis) of young and adult pheasants were analyzed. We found that cadmium exposure of the adults did not affect the number of eggs laid but resulted in more eggs being damaged. Hatchlings were significantly heavier in the cadmium-treated group (21.36±2.28g) compared to the control group (20.91±1.97g) 4 weeks after the cadmium intake. Higher cadmium concentrations were observed in the muscle and kidney tissue of newly hatched pheasants after 4 weeks compared to the cadmium-exposed groups after 8 and 12 weeks. The cadmium concentrations in kidneys and liver increased significantly in adult pheasants. The metal had accumulated especially in kidneys of the adult pheasants and reached levels up to 9.64mg/kg wet weight 3 months after the daily cadmium intake in drinking water. The concentration in liver of the adults was 3.53mg/kg wet weight.
