treatment plan:
scenario 1:
according to the 30 meters with hin mg per kg of body weight deep intramuscular injection, once a day, 3 times for, with the use of blood 2 ml / head, vb12 injection 2 ml to 5 ml, 10 ml / bupleurum injection (pig), head of the general can control the disease, hypothermia, improvement of the severity of the disease in pigs should adopt strong heart infusion.
scenario two:
pigs every year season, with the morninglight honggong chain scattered, static mycoplasma drugs such as prophylaxis |
