What are the benefits of cooperative rearing of young silkworms? Silkworm farmers who know early benefit early

From hatching to cocoon spinning, silkworms generally go through 4 molts and 5 instars. Instars 1 to 3 are called young silkworms, and instars 4 to 5 are called large silkworms or mature silkworms.

The young silkworm stage is the period for building up physical constitution and is the foundation of the entire silkworm rearing period. If young silkworms are raised well, the silkworms have a strong constitution, and in the large silkworm stage they can better resist adverse environments and pathogens. This is beneficial for a bumper cocoon harvest. Therefore, raising young silkworms well is the key to achieving a bumper cocoon harvest.

(1) It facilitates scientific @#@250@#@: the young silkworm stage requires higher temperature and humidity, and a dedicated person must regulate and control temperature and humidity day and night, while a single household finds it difficult to meet the requirements.

(2) It facilitates creating a good rearing environment and doing a good job of disinfection and disease prevention: after implementing cooperative rearing of young silkworms, suitable houses can be selected and built as cooperative rearing rooms for young silkworms, achieving heat preservation and moisture retention, unified disinfection, and effectively separating young silkworms from large silkworms in rearing, which helps young silkworms with very weak disease resistance develop and grow healthily in a safe environment.

(3) It saves labor, materials and mulberry leaves: if 20 households raise 30 sheets of silkworm eggs, 20 people are needed. With cooperative rearing of young silkworms, 1 rearer can handle 4 to 5 sheets in instars 1 to 2. For 30 sheets, only 6 to 8 people are needed, saving about 60% of labor. For expenses such as heating fuel, disinfectant medicines, paper and lighting, cooperative rearing of young silkworms can save more than 50%. Implementing cooperative rearing allows reasonable storage of mulberry leaves, keeps mulberry leaves fresh well, and with fewer feedings, mulberry leaves can be greatly saved.

(4) High economic benefit: implementing centralized supplemental incubation of silkworm eggs gives a high hatching rate of newly hatched silkworms, and the collection of newly hatched silkworms is uniform. This creates important conditions for carrying out scientific silkworm rearing throughout the entire rearing period. Cooperatively reared young silkworms are lively and healthy, with few losses, and cocoon yield and income are 10% to 20% higher or more than without cooperative rearing.
