PRRS is an infectious disease caused by porcine reproductive and respiratory syndrome virus, which is currently a "constant" disease in pig farms.
Once PRRS occurs, the probability of miscarriage and stillbirth in sows is high, and the main manifestations of sick pigs are slow growth, decreased immunity, and difficulty in panting, etc., and can be secondary infected with swine fever, parapigs, epierythrocytosis and other diseases in the middle and late stages.
At present, pig farms generally use vaccines in the prevention and control of PRRS, which is not advisable, and it is unrealistic to rely solely on vaccine immunization to control PRRSV. What we need to do is to improve the pig's own immunity, prevent bacterial mixed infection, and prevent inducing asthma, swine fever and other diseases.
It is recommended to start from the following four aspects for the purification and prevention and control of blue ear in pig farms, especially the last one:
1. Do a good job in biosecurity management, restrict cross-foster care in the delivery room, and prohibit arbitrary adjustment; Strictly control the introduction of seeds to ensure that boars are not poisonous.
2. Scientific immunization vaccination. PRRS positive instability field control can take 2 vaccinations, 14-21 days apart (or less) + partial decontamination, which is the most economical.
3. Effective comprehensive control of epidemic diseases. The main points are to eliminate the source of infection, cut off the transmission route (reduce the environmental viral load) and protect the susceptible population (improve the resistance of the pig herd).
4. In terms of secondary infection control, antibiotics can be appropriately used for drug health care in the pig herd, such as 500g of happiness 100 + tyvanectin + 500g of Longchang bile acid mixture 2000 kg, which helps to suppress blue fungus and purify the pig herd.
The biggest cost of pig raising is feed, animal protection is a small cost, but the input and output is higher, is the key to reducing costs and increasing efficiency, and sometimes can play the effect of "four or two thousand catties".
The main ingredients of Happiness 100 are chlorogenic acid, polysaccharides and flavonoids, which can effectively inhibit the replication of PRRSV, improve the resistance of pigs, and help block the secondary abortion, red and swollen eyes, messy fur, emaciation and other symptoms caused by PRRSV.
