Witness the silkworm farming process in an air-conditioned room

Realizing the potential of the mulberry growing model, Mr. Nguyen Van Cuong - Director of Cuong Nga Honey Cooperative (Quang Diem Commune, Huong Son) spent time and effort visiting and learning from many models inside and outside the province. After many field trips, in September 2022, he boldly brought hybrid mulberry varieties to test planting on 3 hectares of land in Quang Diem Commune. To date, the Cooperative has expanded to 7 hectares of mulberry, achieving a yield of 9 tons/ha.

After having a raw material area, in September 2023, the Cooperative began testing silkworm farming by importing eggs from the Sericulture Research Center in Long Bien District ( Hanoi ). At the same time, to prepare for the farming process, the Cooperative invested in installing a support system, air conditioning and necessary equipment with a total cost of about 100 million VND. However, due to lack of experience in care techniques, the first batch of silkworms had low cocoon productivity, not meeting initial expectations.

Despite initial obstacles, Mr. Nguyen Van Cuong is still determined to pursue the silkworm farming model. With the support of the Central Sericulture Research Center, since June 2024, the Cooperative has gradually mastered silkworm care techniques in both development stages. Currently, the Cooperative focuses on raising high-quality silkworm breeds such as VH 2020 and bi-system silkworm breeds imported from China, creating a solid foundation for the long-term development model.

Sharing about the silkworm raising process, Mr. Nguyen Van Cuong said: “Silkworms are very sensitive to environmental changes. When raising in large quantities, it is necessary to ensure that the temperature in the “nes” (wooden frames about ^1m2 in size, divided into many small square cells of equal size) is always kept stable at 25-30 degrees Celsius, humidity fluctuates around 80-85% for the silkworms to grow healthily. To meet these strict requirements, we invested in an air conditioning system to maintain a stable temperature, creating favorable conditions for silkworms to grow and develop.”

The development process of silkworms goes through 5 stages, called 5 ages, each age lasts about 2 to 3 days. After each molt, the silkworm enters a new age. Starting from the second age, the silkworm enters a period of strong feeding, also known as the "silkworm feeding" stage. At this time, the nutritional needs increase, requiring the breeder to continuously provide fresh mulberry leaves to ensure good silkworm development.

When the silkworms reach the “ripe” stage – that is, they have developed to the point of forming cocoons, the breeders will move them into “nests”. Each silkworm will find a cell to live in, begin the process of spinning silk, wrapping its body and forming a cocoon. It is known that the cooperative currently has 120 silkworm nests.

Cleaning and disinfecting the silkworm breeding area is always a top priority, because silkworms are extremely sensitive to the environment. All cleaning steps must be carried out carefully and according to the correct procedures to ensure that the breeding space is always clean, minimizing the risk of disease or harmful agents. “Silkworm breeding does not allow any subjectivity. To achieve high efficiency, it is imperative to strictly follow the technical procedures, just a little negligence can affect the entire silkworm brood” – Mr. Nguyen Van Cuong shared.





Each box of silkworms weighs 100 grams, after about 15 days of care, will consume about 800 kg of mulberry leaves and harvest 45 - 50 kg of cocoons. With the current market price fluctuating between 180,000 - 200,000 VND/kg, breeders can earn from 14 - 16 million VND/month.

Mulberry cultivation and silkworm rearing are proving to be an effective direction with income levels that are superior to many traditional crops. According to practical experience, ineffective cultivated land areas, if converted to mulberry cultivation combined with silkworm rearing, will bring significantly higher economic value. Up to now, the Cooperative has proactively connected and cooperated with the Mulberry Silk Joint Stock Company (Yen Bai province) to ensure stable output for silkworm cocoon products.

From the practical results, the Cooperative also expressed its hope that people in the areas of Huong Son will promptly grasp the trend and convert ineffective agricultural land to the model of growing mulberry and raising silkworms, creating a new, sustainable and potential direction in rural economic development.
