摘要：猪流行性感冒主要是由流行性呼吸病菌导致的，是一种高危险性传染疾病，兽医常把这种疾病称为猪流感。在养殖中，猪流行性感冒是养殖户高度关注的一种动物疾病，如果没有进行有效防治，可能会给养殖户带来巨大的经济损失，降低出栏率。猪流感容易爆发的高峰期在每年春季和冬季，因为这2个季节昼夜温差较大，温度不均匀，再加上部分养殖户因为场地不足，养殖密度较大，增大了猪流感的传播途径，容易造成大面积的猪流感感染。该文提出猪流感的病理介绍内容，分析猪流感的疾病防控对策。

Abstract：Swine influenza is caused mainly by an epidemic of respiratory bacteria，a high risk sexually transmitted disease that veterinarians often refer to as swine flu. In the breeding，swine influenza is a kind of animal disease which is highly concerned by the breeders. If the disease is not effectively controlled，it may bring huge economic losses to the breeders，and reduce the rate of being taken off the market，couldn't provide people with more meat. The peak season for the outbreak of swine flu occurs in spring and winter every year，because the temperature difference between the day and night is large and the temperature is not uniform in these two seasons. In addition，some farmers have increased the transmission route of swine flu because of insufficient space and high breeding density，could easily lead to a massive swine flu infection. In this paper，the pathology of swine influenza was introduced，and the disease prevention and treatment of swine influenza were analyzed.

0引言

豬流感最早在美国中北部发生，至今已经有100多年的疾病历史，这种疾病会导致生猪出现厌食、嗜睡、呼吸困难等情况。猪流感动物疾病虽然有一定的历史，但是却在20世纪中叶才被世界各个国家所获知。随着畜牧业的发展，养殖户的大量增多，猪流感已经成为全世界范围内生猪养殖过程中常见的一种动物疾病，制约各个国家畜牧养殖业可持续发展。对该疾病的病原、病理变化、临床表现和防控对策等进行探究，降低猪流感发病率，是非常有必要的。

1病理介绍

1.1病原

流感的致病因素是A型流感病毒的侵染，人和动物都会感染这种病毒，其发病特征显著，咳嗽、发热是常见的症状。这种疫病对动物的致死率较低，除了部分免疫力低下、发育不良或因流行性感冒诱发其他疾病的患病猪外，大部分猪不会出现致死情况[1]。……
