Silkworm frass, also known as silkworm excrement, is a highly nutritious feed ingredient. With a crude protein content of 15.4%, it ranks just behind wheat bran and surpasses rice bran and grass, making it an excellent feed option for livestock and poultry. Incorporating silkworm frass into animal diets has proven to be highly effective in many cases.
First, when fed to pigs, silkworm frass helps reduce the need for fine feed while promoting rapid weight gain and increasing the slaughter rate. Sows that consume silkworm frass tend to produce more milk, which benefits their piglets' growth and development.
Second, sheep fed with silkworm frass show increased milk production and higher wool yield. The wool quality is also improved, with some sheep producing hair as long as 14 cm.
Third, cows that are fed silkworm frass become more resilient and better able to handle physical stress, which can improve overall health and productivity.
Fourth, rabbits that consume silkworm frass tend to accumulate more fat and have lower water content, which can enhance meat quality.
Fifth, adding 5% silkworm frass to chicken feed significantly improves the color of egg yolks, making them richer and more vibrant, which is often preferred by consumers.
Sixth, fish raised on silkworm frass experience fewer diseases and grow faster. For every 1,000 kg of silkworm frass used, approximately 100 kg of fresh fish can be produced, making it a cost-effective and efficient feed source for aquaculture.
Despite its high nutritional value, fresh silkworm frass has a short shelf life and is prone to spoilage and mold if not properly stored. To extend its usability, it should either be dried to reduce moisture content to below 15%, or preserved through silage using large containers, cement pits, or other suitable structures. It should be tightly packed and compacted to encourage lactic acid fermentation, which helps preserve the material.
Additionally, it's important to note that silkworm frass may contain pathogens that affect silkworms. Therefore, it should never be mixed with silkworms or kept in close proximity to them to prevent contamination and disease spread. With proper handling and storage, silkworm frass can be a valuable and sustainable feed resource for various animals.
