Feed grade dried silkworm pupae key information
- Nutritional Information
- protein: The content is 50% - 70%, with complete amino acids and rich in essential amino acids, which is better than fish meal.
- Fat: Crude fat 24% - 33%, with a high proportion of unsaturated fatty acids.
- Vitamins: Rich in vitamin B2, D3, etc.
- Minerals: High phosphorus content, contains a variety of major and trace elements.
- other: Contains about 4% active substances such as polysaccharides and antimicrobial peptides.
- Feed Application
- poultry: To improve palatability, add 2.5% - 5% to broilers and 2% to laying hens. Too much will cause off-flavor in meat and eggs.
- Aquatic: Special fish attractant that can partially or completely replace fish meal.
- livestock: Add about 2% to pig feed and 10% - 12% to ruminant feed.
- Advantages
- Protein: High-quality protein source, balanced amino acids, and reduced dependence on fish meal.
- Wide sourcemy country is rich in silkworm pupa resources, with an annual output of 100,000 to 200,000 tons of dry products.
- Low cost: The price is lower than fish meal, reducing feed costs.
The following are frequently asked questions (FAQ) about feed-grade dried silkworm pupae:
Nutrition
- What are the main nutrients of feed-grade dried silkworm pupae?
Rich in protein (over 50%), multiple amino acids, fat, carbohydrates, ash, vitamins A, B2, D and ergosterol. - What are its nutritional advantages compared with other common protein feeds?
Compared with fish meal, it has similar content of most amino acids and better price. Compared with plant protein feeds such as soybean meal, it has a more balanced amino acid composition and a high content of sulfur-containing amino acids.
Quality Standards
- What are the industry quality standards for feed-grade dried silkworm pupae?
Crude protein, crude fiber and crude ash are used as indicators. For example, for silkworm pupae, the first-grade crude protein is ≥50.0%, crude fiber is <4.0%, and crude ash is <4.0%; the second-grade crude protein is ≥45.0%, crude fiber is <5.0%, and crude ash is <5.0%; the third-grade crude protein is ≥40.0%, crude fiber is <6.0%, and crude ash is <6.0%. - How to judge the quality of feed-grade dried silkworm pupae?
The high-quality ones are in the form of brown pupa particles and a small amount of fragments, with uniform color, no mold, lumps or odor. It can also detect whether the indicators such as moisture and crude protein meet the standards.
Application
- What animal feeds are feed-grade dried silkworm pupae suitable for?
It is suitable for poultry, livestock and aquaculture animal feeds. - What is the general addition ratio in animal feed?
Ruminants account for 10%-12% of the total feed; chickens, ducks and geese account for 5%-7%; pigs account for 15% and quail account for 5%.

Prevent insect infestation and mildew, conduct regular inspections, and handle abnormalities such as moisture in a timely manner.
Processing
- How are silkworm pupae processed into feed-grade dry silkworm pupae?
It is first dried, sieved to remove impurities, and crushed. It is then degreased and deodorized by boiling and washing methods, and finally dried. - How to ensure that nutrients are not lost during the processing?
The temperature should not be too high and the time should not be too long during drying. Low-temperature drying, freeze-drying and other methods can be used.
