1978年,我场有两个生产队的猪,先后发生一种原因不明的热性病,其临床症状很像流感,但按流感治疗无效。因此我们进行了诊断,治疗方面的探讨,其结果如下: (一)发病及流行情况: 78年9月场直菜队50公斤左右育肥猪群中3-4天内发病16头,病猪占发病群的50％以上。病后第16天死亡7头,死亡率为43％。 78年11月份二分场十一连20-40公斤重的育肥猪,数天内发病35头,病猪达发病群的50％以上。发病5-6天死亡12头,死亡率为34％。 (二)临床症状: 体温升高到40.0—41.5℃,食钦减退,或废绝,精神萎顿,喜卧,粪便干固,
In 1978, there were two pigs from our production team. There was an unexplained fever disease. The clinical symptoms were very similar to those of flu, but the treatment was not effective. Therefore, we conducted the diagnosis and treatment. The results are as follows: (I) Incidence and prevalence: In September of 2007, the number of fattening pigs in the 50 kg or so finishing group was 16 in 3-4 days. More than 50% of the group. Seven deaths occurred on the 16th day after the illness, and the mortality rate was 43%. In November of the year 78, the second round of the finishing line was a fattening pig weighing 20-40 kg. The number of diseased pigs reached 35 in a few days, and sick pigs accounted for more than 50% of the disease group. Twenty deaths occurred 5-6 days after the onset, with a mortality rate of 34%. (b) Clinical symptoms: The body temperature rises to 40.0-41.5°C, the appetite decreases, or is discarded, the spirit is wilted, and the feces are dry and firm.
