Frequent respiratory disease outbreaks in pig farms: where exactly do the causes lie?
Frequent respiratory disease outbreaks in pig farms: have you ever carefully considered the causes?
Vaccines
For example, if the pseudorabies vaccine on a pig farm is not done well, and the sow herd is not routinely given blue ear (PRRS) vaccine, and blue ear has never been purified, then once there is the slightest disturbance on the farm it will cause respiratory infection, resulting in a relatively high mortality rate.
Ventilation
Generally, when autumn or winter comes, pig farms will seal up the windows, sealing them tightly, thinking that if the wind cannot get in, respiratory disease will not occur. This is actually a big mistake.
Especially in autumn and winter, pig farms should ventilate frequently, and should also learn which time periods are best for ventilation.
Mold
Some farmers, in order to save on breeding costs, do not use mold removers for finishing pigs, always thinking that the feed is very dry, has no mold, and that they are using the best corn, and so on. In fact, this is not the case. Mold toxins generally cannot be seen with the naked eye. If you want to see whether the feed has mold, look at whether the sprouting part of the corn has black spots. The "mold" problem is something many farmers ignore, yet mold toxins are a major killer in the breeding industry. For example, they cause vaccine immunization failure, sows not coming into heat, sow miscarriage, stillbirth and mummified fetuses, miscarriage and premature birth, the occurrence of respiratory disease in pig farms, and repeated coughing and panting.
When respiratory disease appears in a pig farm, it is always accompanied by blue ear, making the mixed viral infection very difficultto treat. Do a good job of prevention in advance to prevent respiratory disease and let piglets grow up healthily. Even if they get respiratory disease, with prevention done in advance, it will still be easierto treatwhen the time comes, and there will not be a large mortality rate. For early prevention, tilmicosin, doxycycline, or traditional Chinese medicine preparations, etc. can be added to the feed. (Source: Today's Pig Farming)
