Insect farming has been suggested as a good alternative to conventional livestock farming for the growing demand of food and feed production. One of the most well-known edible insects is the silkworm, larva of the silk moth (Bombyx mori). This insect is reared because of their commercially valuable products, namely the silk filaments. As for food, sericulture provides larvae or pupae inside cocoons as sources of nutritious proteins. The objective of this study was to investigate if silkworms can be successfully reared on a vitamin D enriched diet and can result in a healthy, high protein, and vitamin D enriched end product. The results may aid the current and worldwide protein transition and it may help in reducing the vitamin D deficiency problem.
