Two trials were conducted with male Cobb chicks to investigate the interaction between experimental Eimeria acervulina infection and dietary excesses of Co and Mn. Eimeria acervulina infection depressed rate and efficiency of weight gain, increased bone mineral retention and exacerbated Co toxicity. A significant Co X Mn interaction was observed in growth rate and efficiency of gain and in Co and Mn concentration in some tissues as well. This interaction was present both in uninfected chicks and in coccidiosis-infected chicks. Excesses of dietary Co and Mn increased tissue Co and Mn concentrations, respectively. Excess Co also increased Mn accumulation in kidney, bile and the tibia.
用雄性科布雏鸡进行了两项试验，以研究实验性堆型艾美耳球虫感染与日粮中过量的钴和锰之间的相互作用。堆型艾美耳球虫感染降低了体重增加的速率和效率，增加了骨矿物质潴留，并加剧了钴的毒性。在生长速率和增重效率以及某些组织中的钴和锰浓度方面也观察到了显著的钴×锰相互作用。这种相互作用在未感染雏鸡和球虫病感染雏鸡中均存在。日粮中过量的钴和锰分别增加了组织中的钴和锰浓度。过量的钴还增加了肾脏、胆汁和胫骨中锰的蓄积。
