DISINFECTION DONE INCORRECTLY – THE REASON RESPIRATORY DISEASE IN PIGS RECURS
Respiratory disease in pigs is one of the major problems causing significant losses in farms due to high medication costs, slow weight gain, and a high rate of relapse. In many cases, pigs recover for only a few days and then start coughing, showing difficulty breathing, and reduced feed intake again.
Many farmers assume that the cause comes from unstable weather or ineffective medication. However, in reality, most recurring cases are closely related to improper disinfection practices in the barn environment.
If the rearing environment still contains bacteria, viruses, and mold, pigs can easily become re-infected even after successful treatment.
1. Why Do Respiratory Diseases in Pigs Easily Recur?
Hot, humid, and manure-contaminated barns create ideal conditions for pathogens to develop rapidly.
Common disease agents include:
PRRS (Porcine Reproductive and Respiratory Syndrome)
Mycoplasma
Streptococcus
E. coli
Influenza virus
Mold fungi
These pathogens can survive for a long time in:
Barn floors
Feed troughs
Water troughs
Barn walls
Water pipelines
Enclosed air environments
If disinfection is not effective, bacteria and viruses will continue to persist in the farming environment. This is the main reason pigs repeatedly suffer from respiratory illness, prolonged coughing, and weakened immunity.
2. Common Mistakes in Barn Disinfection That Cause Re-infection
- Spraying disinfectant while the barn is still dirty
This is a very common mistake in many farms.
Farmers often spray disinfectants while manure, leftover feed, and organic matter are still present. This significantly reduces the effectiveness of the disinfectant.
Consequences:
The disinfectant cannot reach pathogens
Bacteria and viruses remain in the barn
Pigs quickly relapse
Correct practice:
Remove all manure and waste
Wash the barn floor thoroughly
Let the barn dry before disinfection
- Missing high-risk contamination areas
Many farms only spray the floor and forget areas with high bacterial load such as:
Feed troughs
Water troughs
Barn walls
Walkways
Water pipelines
Farming tools
These are high-risk areas that can spread pathogens.
Effective disinfection approach:
Spray the entire barn area
Soak tools for 30–60 minutes
Perform periodic disinfection even when there is no outbreak
- Diluting disinfectant incorrectly
Incorrect mixing ratios significantly reduce the ability to eliminate:
Viruses
Bacteria
Mold fungi
Mycoplasma
Even a small amount of remaining pathogens can easily cause reinfection.
Common signs:
Persistent coughing in pigs
Recurrent illness
Slow weight gain
High medication usage
3. Effective Disinfection Solution with Nano Silver
Nano Silver – A Next-Generation Disinfection Technology
Nano Silver is a broad-spectrum disinfectant containing 1000 ppm silver nanoparticles with ultra-small particle sizes of 2–10 nm.
Key advantages:
Deep penetration
Rapid bacterial elimination
Supports elimination of viruses, fungi, and Mycoplasma
Reduces recurrence of respiratory diseases in pigs
Lowers pathogen pressure in barns
Applications of Nano Silver in Pig Farming
Nano Silver is widely used for farm hygiene and disinfection thanks to its ability to control many dangerous pathogens.
Key uses:
Disinfection of barns and farming equipment
Water source sterilization
Support control of PRRS, FMD, and avian influenza
Disinfection of open wounds and mastitis
Reduction of odor and harmful gases in barns
Usage Instructions for Nano Silver
Routine disinfection
Mix 1 liter with 300–500 liters of water
Spray every 10–15 days
During disease outbreaks
Mix 1 liter with 150–200 liters of water
Spray every 3–5 days
Water disinfection
Mix 1 liter with 10,000 liters of water
Wound disinfection
Mix 1 liter with 3 liters of water
Important Notes for Barn Disinfection
To achieve optimal results, farmers should:
Do not mix with other chemicals
Do not spray before cleaning the barn properly
Shake well before use
Spray thoroughly on floors, walls, and surrounding areas
4. Conclusion
Recurring respiratory disease in pigs is not only caused by weather or ineffective treatment. In many cases, the main reason is improper disinfection practices that allow pathogens to remain in the farming environment.
To sustainably reduce respiratory disease, farmers should:
Clean barns properly
Disinfect regularly
Control water and equipment hygiene
Use high-quality disinfection solutions such as Nano Silver
Proactive and correct disinfection is the key to keeping pigs healthy, reducing medication costs, minimizing disease outbreaks, and improving long-term farming efficiency.
