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.

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.

suggestion

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.
