笔者大概统计2001-2007年猪只死亡率大致呈0、20%、40%、60%、80%,2008-2012年猪只死亡率大致呈60%、40%、20%、0这样的规律。发病率最低的时期猪低价,这是由于猪数量的增加没有其他原因,2012年上半年猪价格就是相当低。因此本病是决定猪数量的一个调节杠杆,因为猪是高产动物,符合自然辩证法法则和进化论的规则。
The author roughly estimated that the death rate of pigs in 2001-2007 was roughly 0, 20, 40, 60 and 80%. The death rate of pigs in 2008-2012 was roughly 60%, 40%, 20% and 0 . Pigs of the lowest morbidity period were low-priced due to no other reason for an increase in the number of pigs, which was quite low in the first half of 2012. Therefore, the disease is a regulatory lever that determines the number of pigs, because pigs are high-yielding animals in line with the laws of natural dialectics and evolutionary rules.
