Investigation and Analysis of Death, Culling, and Recovery Time of Pigs with Porcine High Fever Disease
Investigation and Discussion on Death, Culling, and Recovery Time of Pigs with Porcine High Fever Disease
Over the past year, porcine "high fever disease" has gripped the nerves of every pig farmer and every person serving pig farmers. Everyone is eager to understand its patterns and hopes to find the best control methods. Unfortunately, to date, no authoritative conclusion that can withstand debate has emerged domestically or internationally.
Over the past six months or more, I have personally handled no fewer than 100 cases conforming to the characteristics of "porcine high fever disease," and I have learned of dozens of cases treated by others. I have found that no pig farm has reached a 100% mortality rate among sick pigs (even if there were, it would be due to artificial culling). The disease course varies in length, and the effectiveness of medication in the middle and late stages ranges from good to poor. Today I had an idea to compile and summarize the recorded cases to share with colleagues (a report will be available in a few days). At the same time, I am throwing out a brick to attract jade, and I sincerely invite everyone to investigate and discuss.
--------------------------------------
Support!! Brothers, let's start discussing
--------------------------------------
Defining indicators for porcine "high fever disease" (personal opinion, modifications and additions welcome):
1. Herd outbreak: affected pigs account for more than 50% of the pigs on hand, and the interval between onset among pigs in the same pen does not exceed 5 days;
2. Affected pigs are regardless of breed, age, or sex;
3. Body temperature above 40 degrees; in the first 5 days of onset, no medication can prevent the disease from recurring; some affected pigs show purple ear symptoms in the middle and late stages;
4. The herd disease course lasts more than 10 days; generally, the disease course of an individual pig lasts more than 3 days;
--------------------------------------
Discussion topics: Calculate the disease course based on pigs in the same pen or pigs with simultaneous onset as one group, and use one household, one rearing unit, or one farm as one case
1. Number of days from onset to the death of the first pig;
2. How many pigs were affected? How many died from disease? How many were culled and how many surviving pigs were disposed of?
3. Number of days required from onset to full recovery;
--------------------------------------
The onset seems to be sporadic, not a large-scale outbreak. If it is in piglets about to be weaned or after weaning, mortality can reach more than 80%. I suggest not using medication, as it can be said to be ineffective and a waste!! It can last half a month. I hope others will correct and supplement. Thank you!!!!
--------------------------------------
Symptoms vary, prevention and treatment methods vary, treatment effects vary
--------------------------------------
I am from Hubei. Based on my statistics, the incidence rate of this high fever disease should account for 80%, and the mortality rate is often around 30%-60%!
--------------------------------------
Because the actual conditions of pig farms differ (such as immunity levels, sanitation and disinfection status, etc.), the secondary infections also differ, which determines the incidence rate and mortality rate. In particular, the mortality rate is certain to vary greatly.
--------------------------------------
Next year will be a happy year for pig farming. Embrace golden pigs and make big money.
--------------------------------------
To put it plainly, there is no secret remedy or miracle drug for pig farming. It still comes down to proper standard techniques.
--------------------------------------
What are the main symptoms?
--------------------------------------
Are there any specific methods for prevention and treatment?
