High-Protein Dried Silkworm Pupae for Animal Feed
High-protein dried silkworm pupae have rapidly established themselves as one of the most cost-effective and nutritionally superior insect-based feed ingredients in the global animal nutrition market. Derived from the silkworm Bombyx mori, these dried pupae are a valuable by-product of the silk industry, transforming what was once considered processing waste into a premium feed commodity. With crude protein levels consistently exceeding 50% on a dry matter basis and a well-balanced amino acid profile, they are increasingly adopted by aquaculture operations, poultry farms, swine producers, and exotic pet suppliers worldwide. As the demand for sustainable, non-GMO protein alternatives intensifies, dried silkworm pupae offer a compelling solution that aligns with both economic efficiency and environmental responsibility. Their long shelf life, low moisture content, and ease of incorporation into compound feed formulations make them an indispensable ingredient for modern animal husbandry.
What is High-Protein Dried Silkworm Pupae?
Dried silkworm pupae are the desiccated pupal stage of Bombyx mori (Linnaeus, 1758), a domesticated moth belonging to the family Bombycidae. After silk filaments are reeled from cocoons during textile processing, the enclosed pupae are extracted, cleaned, and subjected to controlled drying methods. The resulting product is a compact, amber-to-brown ovoid body measuring approximately 15–20 mm in length and 8–12 mm in diameter, offering a dense, shelf-stable protein source for a wide range of livestock and companion animals.
High-Protein Dried Silkworm Pupae Breeding and Rearing Process
Commercial silkworm pupae intended for animal feed originate from certified Bombyx mori sericulture farms operating under strict biosecurity protocols. Larvae are reared on fresh mulberry leaves (Morus alba) in temperature-controlled environments maintained at 24–28°C and 70–85% relative humidity. Following cocoon formation, pupae are harvested, thoroughly washed, and dried using hot-air drying tunnels or freeze-drying systems at temperatures between 60–80°C to achieve a final moisture content of ≤8%, ensuring microbiological safety and extended shelf stability.
High-Protein Dried Silkworm Pupae Biological Specifications
Our dried silkworm pupae deliver a crude protein content of 52–58% on a dry matter basis, with a fat content ranging from 26–32% and a moisture level of ≤8%. The amino acid profile is particularly rich in lysine (3.2–3.8 g/100g DM), methionine (1.4–1.8 g/100g DM), and threonine (2.1–2.6 g/100g DM). Individual pupae measure 15–20 mm in length with a unit weight of 0.8–1.2 g. Ash content is maintained at ≤5%, and the product is free from artificial additives, preservatives, and antibiotic residues.
