血浆中铜的含量与全血铜的含量相似,血浆或血清铜的水平是动物铜状况的较好的指标。但是并非所有的循环血液中的铜对动物来说是可利用的。对妊娠牛而言,血清铜的水平从怀孕后第三个月到第五个月开始增高,而血清铜的水平却不是铜缺乏症的唯一可靠的指标。有人还发现,铜在肝脏中的分布也不是完全均匀一致的,尾状叶中的铜含量比右或叶左叶都要高些。牛铜缺乏的症状及影响:成年母牛的生育力和公牛的精子质量下降,皮毛粗乱,生
The content of copper in plasma is similar to that of whole blood copper, and the level of plasma or serum copper is a better indicator of copper status in animals. But not all circulating blood copper is available to animals. For pregnant cattle, serum copper levels begin to increase from the third to the fifth months of pregnancy, whereas serum copper levels are not the only reliable indicator of copper deficiency. It was also found that the distribution of copper in the liver is not completely uniform, the caudate lobe of copper content than the right or left leaves are higher. Symptoms and effects of lack of bovine copper: the fertility of an adult cow and the sperm quality of the bull are reduced, the fur is rough,
