Cultivating method of zinc-rich yellow mealworm

Abstract

The invention relates to a cultivating method of zinc-rich yellow mealworm, belonging to the technical field of cultivation. The method comprises the steps of cultivating larvae and cultivating enriched zinc, specifically comprising the steps of: cultivating the yellow mealworm to be middle-age stage and old-age stage according to a routine method; transferring the middle-aged yellow mealworm andthe old-aged yellow mealworm into a special cultivating box; cultivating with wheat bran; daily cultivating with 0.6-5%-2.0% of zinc sulfate water solution with a water drinking device in a special cultivating box, wherein the usage amount is 600ml/kg polypide; and collecting and using after the 12-15 days of continues cultivation. The method can improve the content of microelement zinc in the yellow mealworm by 3-4 times to reach about 400mg/kg.

Description

Technical field [0001] The invention relates to a method for breeding yellow mealworms, belonging to the technical field of breeding. Background technique [0002] Tenebrio molitor (also known as yellow powder beetle, commonly known as breadworm, dry shrimp) Tenebrio molitor Linnaeus belongs to Coleoptera Coleoptera, Carabidae, mealworm belongs to Tenebrio. The adult body of Tenebrio molitor is about 18mm long, flat, oblong, dark brown and shiny; the larva is golden needle type, the newly hatched larva is white, and the later is yellowish brown. The back and front edges of each node are light brown, and the internodes and ventral surface are light yellow White, mature larva body length is 28~33mm. Tenebrio molitor is a kind of warehouse pest distributed all over the world. Because it is rich in protein (the larval protein content is 48% to 59%), it is a high-quality animal protein source with high nutritional value and a wide range of feed sources. The feed conversion rate is h...
