Abstract

The invention discloses a preparation method of a biological feed additive based on hermetia illucens. The method comprises the following steps: cleaning hermetia illucens larvae, performing microwave drying, and crushing the dried hermetia illucens larvae to 20-200 meshes to obtain dried hermetia illucens powder for later use; preparing by weight, wherein 50-90% of dried insect powder, 30-50% of corn flour, 1-10% of a mixed microbial agent and 1-10% of a mixed enzyme preparation are adopted; adding sterile water according to the weight ratio to enable the water content of the materials to be 30-60%, and performing constant-temperature and constant-humidity fermentation for 12-36 hours under the conditions that the temperature is 25-40 DEG C and the RH is 40-90%; and dehydrating the fermented material in a freeze-drying manner, crushing the material to 100 meshes, and packaging. Compared with beans, the composition and proportion of amino acid in protein of the hermetia illucens are more suitable for animals to absorb, the proportion and variety of grease of the hermetia illucens are more suitable for animal growth, the nutrition proportion of the hermetia illucens is researched, and the feed additive based on hermetia illucens has guiding significance.

Description

technical field [0001] The invention belongs to the field of feed processing, and relates to a feed biological additive for aquatic product breeding and livestock and poultry breeding and a preparation method thereof, in particular to a preparation method and application of a black soldier fly-based biological feed additive. Background technique [0002] my country is the largest farming country in the world. In 2019, the total output of poultry meat, livestock meat and aquatic products in my country is 165 million tons, and the feed raw materials required are much higher than the domestic production capacity. For this reason, my country needs to import a large amount of feed raw materials every year, and the amount of soybean meal imported by my country from abroad has reached 10,000 tons every year. [0003] Black soldier fly larvae are a brand-new insect feed material, and its protein content and oil content are far higher than those of soybeans. The crude protein conte...
