What do experts recommend after two "accidents" at chicken farms in Ha Tinh?

Within just one month, two incidents occurred consecutively at closed farms in Ha Tinh, killing 18,000 chickens. The cause was determined to be an electrical problem, the fan system not working, causing the chickens to go into heat shock and die.

2 electrical incidents caused major damage

At 11:30 p.m. on August 7, 2023, a large-scale closed chicken farm of Mr. Phan Van Xuan's family (born in 1978, residing in village 3, Phuc Dong commune, Huong Khe) had an incident. The 3-phase power system supplying the cooling fan lost 1 phase, causing the circuit breaker to trip, and all 9 fans in the barn stopped working. As a result, more than 10,000 chickens (weighing 2.7 - 3.2 kg/chicken) died.

Mr. Phan Van Xuan's family farm has a rooftop solar power system and a specialized transformer station.

Mr. Phan Van Xuan lamented: “The unfortunate thing is that at that time, only the fan system had a problem, but the lighting system was still working normally, so the workers did not detect it. From the time the problem occurred until the workers discovered it, it took about 1 hour. After that, we turned the circuit breaker back on, so about 3,000 chickens in the coop survived. All the dead chickens were ready to be sold according to the contract signed with the affiliated enterprise, the initial damage was about 1.5 billion VND.”

It is known that Mr. Phan Van Xuan's farm cooperates with Japfa Comfeed Vietnam Co., Ltd. for production. The farm has a guaranteed power source, the electrical system after the meter is designed according to modern livestock barn standards. The farm invested in a rooftop solar power system, a specialized transformer station and a generator system to prevent power outages. However, because the fan problem was not detected in time, the family suffered great losses.

Mr. Vo Van Le - Chairman of the People's Committee of Phuc Dong commune said: "As soon as the cause of the chickens' heat shock and death was determined due to the fan system not working, in order to help the family "save" the investment capital for raising livestock, the commune reported to the superiors. Agencies and organizations from the district to the commune and village stepped in to support, staying up all night to process the suffocated chickens and take them to consumption (about 1,000 chickens). The large amount of chickens that could not be processed and did not ensure quality, the commune rented machinery and provided disinfectant chemicals, and buried them according to regulations".

Not long before, at noon on July 9, 2023, Mr. Nguyen Huy Pho's family (living in Thanh My village, Thuong Loc commune, Can Loc) also encountered a similar incident. The 3-phase power system supplying the fan lost 1 phase, causing the fan system to stop working. Unfortunately, from the time of the incident until it was discovered, about 45 minutes to 1 hour passed, so more than 8,000 chickens died, causing a loss of nearly 1 billion VND.

People help Nguyen Huy Pho's family process dead chickens to minimize damage.

Mr. Nguyen Huy Pho said: “The chickens were about to be sold. If we had discovered the problem and fixed it in time, and quickly restored the power, such heavy damage would not have occurred. There were only about 4,500 chickens left in the entire coop. The government, organizations and neighbors quickly intervened, “rescuing” more than 1,000 suffocated chickens, helping the family recover some of their investment capital.”

About 3,000 chickens of Phan Van Xuan's farm survived the incident.

Regarding the above two incidents, Mr. Tran Hung - Head of the Department of Animal Husbandry and Veterinary Medicine of Ha Tinh said: "In cases of livestock and poultry dying of unknown causes or dying with signs and suspected of being infected, the unit will coordinate to collect samples for testing. However, with the two farms in Huong Khe and Can Loc, it has been determined that the chickens died due to problems with the ventilation system. The previously dead chickens were healthy, when discovered dead, there were no unusual signs, so they could be processed and preserved, the products still ensured food hygiene and safety. As for the chickens that died for a longer period of time and did not ensure quality, they were destroyed by local authorities and specialized agencies according to regulations".

Always be proactive to limit risks

In closed farming conditions with high density, an electrical problem lasting only 15 minutes can affect the livestock. According to electricity experts, to ensure safe farming, facility owners need to comply with standard electrical system design, technical solutions, post-meter electrical systems and ensure proper capacity operation.

Local authorities encouraged Phan Van Xuan's family to overcome the "shock" in animal husbandry.

Mr. Pham Luong Trung - Director of Huong Khe Electricity said: "The power supply for livestock areas in the area is always guaranteed. For the electrical system after the customer's meter, it is recommended that farms must ensure that the design complies with the prescribed technical standards. Electrical equipment in the farm needs to be regularly inspected and maintained, using electrical equipment with appropriate capacity."

Speaking more about this issue, Mr. Tran Anh Dung - Director of Can Loc Electricity noted that farms need to proactively have generators to promptly supply electricity if an incident causes a power outage. In addition, it is necessary to reserve electrical equipment such as fans; research and invest in installing an alarm system when an electrical incident occurs to quickly handle and restore electricity.

Farms need to arrange human resources and means to monitor livestock, and use generators to ensure timely response to electrical problems.

Mr. Tran Hung - Head of the Department of Animal Husbandry and Veterinary Medicine of Ha Tinh recommended: "Ha Tinh currently has 221 pig farms and 15 medium and large-scale chicken farms. Facility owners need to stock according to the density prescribed by the specialized sector (depending on the contract with the enterprises - PV); arrange human resources and equipment to closely monitor the status of livestock 24/24h to promptly detect and handle incidents, especially related to the ventilation system.

At the same time, it is necessary to pay attention to grasp information about power sources, power outage schedules, power outage incidents (if any), proactively use generators and have a plan to cool the barn in case of power outages during the hot season, to avoid affecting the health and development of livestock. Note that facilities strictly implement regulations on fire prevention and fighting in livestock areas...".
