Pregnant sow mold toxin poisoning, be careful!

In November 2012, a more than 800 pig breeding company appeared the phenomenon of acute dying of pregnant sows, and a total of 37 sows died in that month.After investigation, it was ultimately diagnosed with acute deaths caused by mildew toxin poisoning based on multi -kill Bacteria.

basic situation

The breeding company was established in 2006 with more than 800 sows in the deposit.Production and disease prevention and control.

The director’s prosecution: Since entering November, when the sow is pregnant to 1 to 2 months, the sows have become hot, appetite suddenly decreased or abolished, some have abortion, the pig’s body is red, the body temperature rises to 41 ° C ~42 ° C, shortness of breath, short disease course, died 1 to 2 days after symptoms. After death, congestion flowed out in the nostrils, partial abortion, and similar clinical symptoms.


At first I was suspected that the sow abortion caused by the high pathogenic blue ear virus was taken to take 20 blood samples to send the local animal health supervision institution to the veterinary laboratory test, and the high pathogenic blue ear, swine fever, pseudo -rabies and rings were detected.Four antibodies of viruses.The test results show that the four antibodies are uneven, the qualified rate of high pathogenic blue ear virus antibodies is 60%, the pass rate of swine fever virus antibody is 80%, the pseudo -rabies virus antibody qualification rate is 75%, the qualified rate of the ring virus antibody is qualified90%.In this case, the company’s veterinarian technicians suggested that the sows who are pregnant within one month of pregnancy strengthen the immunity of high pathogenic blue ear disease vaccines, each of which is 2 heads;Music and composite multi -dimensional, the treatment effect is not obvious, and death still occurs.


The pregnancy sow, which is acute death, sees the fetal congestion and bleeding obvious; cellulose pleural pneumonia, the cut surface is marble, with cellulose attachment on the pleura, thoracic cavity and pericardium, bronchial and bronchus contain a large amount of foam mucus, enteric membrane lymph nodesSwelling, bleeding, red cut surface; a large amount of mucus on the throat, no ulcers; no fastening swelling at the blind mouth; the liver yellow, the spleen swelling, the groin lymph nodes are enlarged, and the cut surface is black.The fetus has begun to rot and has bad odor.

Preliminary diagnosis: The acute death caused by Multi -kill Bacteria, the antibodies are once poor. The cause of the pathological changes of immune organs can be analyzed. It may be chronic poisoning caused by mold toxins to destroy the sow’s immune system.

Treatment programs

Increase the amount of mold dehydration in the feed, add 1 kg of clear open pellet particles for one ton of sow, add Victori with pigs in drinking water. For sows with clinical symptoms, use Saifu muscle injection, and muscle injection 20ml on the other side of the muscles.Heng Weikang.After 3 days of treatment with this scheme, the sow mortality rate was basically controlled. The sow symptoms of clinical symptoms were eased, and the amount of feeding gradually recovered.


Ensure the quality of sow feed and control the mildew; the pregnant sow is added without interruption to clear the clearing particles to clear heat and detoxify;After the group status, it enhanced immunity for high pathogenic blue ear disease and swine fever.
