EFFECTIVE AFRICAN SWINE FEVER PREVENTION: THE “GOLDEN” GUIDE TO PROTECTING LIVESTOCK

African Swine Fever (ASF) is showing increasingly complicated developments in many regions, directly threatening the livelihoods and income of livestock farmers. With a mortality rate of up to 100%, understanding disease prevention measures is essential to avoid devastating losses.

1. How Dangerous Is African Swine Fever?

African Swine Fever is a highly contagious viral disease that affects pigs of all ages. The most dangerous characteristics of this virus include:

Extremely high resistance: The virus can survive for 3–6 months in raw meat and is only destroyed at temperatures above 70°C.
Nearly 100% mortality rate: Almost all infected pigs die, causing severe economic losses.
Multiple transmission routes: The virus spreads through respiration, digestion, direct contact, or indirectly through transportation vehicles and contaminated food waste.

Note: ASF does not infect humans, but humans can act as major carriers by spreading the virus through clothing, footwear, and vehicles.

2. Early Signs of African Swine Fever in Pigs

Farmers should monitor their pig herds daily. If the following symptoms appear, pigs should be isolated immediately:

Sudden high fever: Body temperature reaches 40–42°C, pigs become lethargic and stop eating.
Piling behavior: Pigs tend to huddle together or lie on top of each other.
Skin discoloration: Thin-skinned areas such as ears, abdomen, chest, and legs may turn red or bluish-purple with hemorrhagic spots.
Digestive and respiratory disorders: Rapid breathing, difficulty breathing, vomiting, and bloody diarrhea.

3. The “5 NOs” Rule – A Strong Shield Against ASF

Every livestock household should strictly follow these core prevention principles:

NO hiding outbreaks: Report sick pigs immediately to veterinary authorities.
NO trading or transporting: Never move or sell sick or dead pigs.
NO slaughtering or consuming: Do not process or consume infected pigs.
NO improper carcass disposal: Never dump pig carcasses into rivers, streams, or the environment.
NO untreated leftover food: Kitchen or restaurant leftovers must be thoroughly heat-treated before feeding pigs.

4. Biosecurity Measures in Pig Farming

To proactively prevent ASF, farmers should strictly apply the following measures:

Cleaning and Disinfecting Pig Farms

Spread lime powder: Apply lime at entrances, pathways, and around pig housing areas.
Regular disinfection: Use disinfectants such as iodine or lime powder at least 2–3 times per week.
Clean feeding equipment: Ensure feed and water sources are clean and disinfected.

Strict Farm Access Control

Minimize access by strangers and traders to pig farming areas.
Farm owners should use separate protective clothing when entering pig pens.
Only purchase piglets with clear origins and official quarantine certificates.

Strengthening Immunity and Vaccination

Supplement feed with Vitamin C and B-Complex to improve pigs’ immune systems.
Proactively vaccinate pigs against ASF according to local veterinary guidelines.
