example 1

[0016] Example 1. Feed with selenium-enriched wheat bran

[0017] Put the obtained black soldier fly adults in a 2m*2m*2m gauze, put rotten flowers, fruits, vegetables or poultry manure in the gauze as the egg-guiding substrate, keep the humidity at 60-90%, and place the fertilized eggs above the substrate at the same time. For egg box, the temperature is controlled at 20-40°C, the air humidity is 40-90%, and the egg-laying is stimulated under the condition of natural light. Eggs collected on the same day were placed in an incubator under the same conditions for incubation. After 2 to 5 days after the larvae hatched, wet feed was added to the larvae cultivation pot for cultivation. The feed used is moist wheat bran with a water content of 60-90%, and 40 mg of selenium-enriched yeast (based on the weight of selenium element) is added per kilogram of feed. The inoculation ratio is 1000-2000 young larvae / kg larvae feed, the temperature of larvae feeding and transformation is con...

[0018] Example 2 Feed with selenium-enriched rice bran

[0019] Put the obtained black soldier fly adults in a 2m*2m*2m gauze, put rotten flowers, fruits, vegetables or poultry manure in the gauze as the egg-guiding substrate, keep the humidity at 60-90%, and place the fertilized eggs above the substrate at the same time. For egg box, the temperature is controlled at 20-40°C, the air humidity is 40-90%, and the egg-laying is stimulated under the condition of natural light. Eggs collected on the same day were placed in an incubator under the same conditions for incubation. After 2 to 5 days after the larvae hatched, wet feed was added to the larvae cultivation pot for cultivation. The feed used is rice bran with a water content of 60-90%, and 40 mg of selenium-enriched mineral powder (based on the weight of selenium element) is added per kilogram of feed. The inoculation ratio is 1000-2000 young larvae / kg larvae feed, the temperature of larvae feeding and transformation is con...

[0020] Example 3 Feed with fresh pig manure enriched with selenium

[0021] Put the obtained black soldier fly adults in a 2m*2m*2m gauze, put rotten flowers, fruits, vegetables or poultry manure in the gauze as the egg-guiding substrate, keep the humidity at 60-90%, and place the fertilized eggs above the substrate at the same time. For egg box, the temperature is controlled at 20-40°C, the air humidity is 40-90%, and the egg-laying is stimulated under the condition of natural light. Eggs collected on the same day were placed in an incubator under the same conditions for incubation. After 2 to 5 days after the larvae hatched, wet feed was added to the larvae cultivation pot for cultivation. The feed used is fresh pig manure with a water content of 60-90%, and 40 mg of sodium selenite (calculated by the weight of selenium element) is added per kilogram of feed. The inoculation ratio is 1000-2000 young larvae / kg larvae feed, the temperature of larvae feeding and transformation...

Abstract

The invention provides a breeding method of selenium enriched black soldier fly larvae. Inorganic selenium or organic selenium is added into feed of the black soldier fly larvae and the concentration of selenium content in the feed of the black soldier fly larvae is controlled at 10 to 80 mg every kg. The selenium is added into the breeding feed of the black soldier fly larvae to obtain the high selenium content of black soldier fly larva products and accordingly the functional value of the black soldier fly larvae is significantly improved. The selenium is combined with protein and polysaccharide organically in the black soldier fly larvae after bioconversion and accordingly the toxic and side effect and the gastrointestinal stimulation of the chemical selenium are eliminated and the selenium can be absorbed and utilized efficiently and securely.

Description

technical field [0001] The invention relates to a selenium-enriched cultivation method for insects, in particular to a selenium-enriched cultivation method for black soldier fly larvae. Background technique [0002] Black soldier fly larvae are high-quality protein resources with comprehensive nutrients. They contain 42% crude protein and 35% fat. Gadfly larvae also contain a variety of trace elements needed for life activities. They are excellent animal protein feeds and delicious fresh bait for special economic animals. etc., the growth is significantly accelerated, and the effect of increasing production is good. It is a good feed additive and food attractant for various animals and pets. Fly maggots also contain other necessary nutrients in a sufficient amount of human food, and each nutritional index is greater than protein nutrients such as chicken, pork, beef, and soft-shelled turtle. [0003] Selenium is a multifunctional life nutrient, which can scavenge free radi...
