What to do when nursery pigs have pale skin, are emaciated and coughing? One solution to the hard-to-raise problem

Why are nursery pigs generally so hard to raise?

At present, the nursery pig stage on pig farms is generally hard to manage, with a high incidence of disease, especially stubborn diarrhea, pale skin, curled hair and emaciation, coughing and panting, and consistently high mortality and culling rates, which has become a headache for many pig farms. Even if you give injections until your hands are raw and you are physically and mentally exhausted,pig diseasesstill come back again and again, to no avail!

The reasons are closely related to the following six points:

1. Great weaning stress: leaving the sow, the ration changing from liquid milk to solid feed, moving to an unfamiliar environment, being separated from littermates, vaccine immunization and other stresses reduce the pigs' disease resistance.

2. The immune system of nursery pigs is not fully developed, and they are in an immune blank zone, so their immunity is poor.

3. Nursery pigs are not fully developed, and various physiological functions are weak.

4. Ammonia in the barn and the damage from toxins such as vaccines, antibiotics and moldy feed further damage the internal organs and affect the pigs' physiological functions.

5. Poor sow health leads to low antibody levels in piglets, making them weak and prone to illness.

6. Weak piglets produced for various reasons often become the initiating link and trigger of disease outbreaks on pig farms.

PRRS and circovirus are the two major killers of nursery pigs

In addition to the above six points, the two diseases that harm nursery pigs the most are PRRS and circovirus. Both are immunosuppressive diseases and are very likely to damage immune organs, causing secondary infections in the herd such as Haemophilus parasuis and Streptococcus, thereby causing relatively high mortality.

Circovirus mainly harms piglets 2 to 3 weeks after weaning. The most common thing we see in production is progressive emaciation or stunted growth in the herd, which is also a necessary clinical symptom for diagnosing PMWS. Other symptoms include anorexia, depression, slow movement, pale skin, rough coat, and difficulty breathing, with coughing as a feature. Less commonly found symptoms are diarrhea and central nervous system disorders.

After infection with PRRS, the body surface skin becomes cyanotic and hemorrhagic. When the skin is severely cyanotic, it appears blue-purple, hence the name "blue ear disease." When nursery pigs develop PRRS, they often show high fever, reduced feed intake or even refusal to eat, and the "three blue" phenomenon: blue-purple swelling and cyanosis around the eyes, blue-purple cyanosis of the snout, and blue-purple cyanosis of the ears.

In view of the current nursery stagepig diseasesbeing complex and extremely difficult to manage, Saike Group independently launchedZhanlan, which can effectively cleanse toxins in sows' bodies as well as PRRS and various mixed infections caused by PRRS. It takes effect quickly and is well received by the market.
