Clinicopathology of iron-deficiency anemia of pigling in close aluminium alloy pig house

以铝合金全封闭式猪舍饲养的月龄杂交仔猪发生典型缺铁性贫血病。29窝209头仔猪发病率为90.9％,致死率为68.42％。病猪呈现典型贫血症状。血色素含量<30g/L,红细胞总数下降至1.65×10^(12)/L。尸检可见贫血、黄疸、水肿变化。组织学检查,肝小叶中心坏死,红骨髓红细胞系增生,脾、肝、淋巴结呈现髓外造血现象。肝、脾中铁的含量仅为正常的3.32％及11.72％,铜、钴含量接近正常。治愈及亚临床康复猪双月龄体重较正常低38.81％,饲料消耗增加29.13％。
