Abstract
The invention relates to a selenium-rich mushroom bran feed, a preparation method of the feed, and a method for cultivating selenium-rich barley pests by using the selenium-rich mushroom bran feed. Selenium-rich mushroom bran is taken as a main raw material of the selenium-rich mushroom bran feed; the content of the selenium-rich mushroom bran in the selenium-rich mushroom bran feed is 5-30wt%; the content of selenium in the selenium-rich mushroom bran is 50-250mg/kg; the ultimate content of selenium in the selenium-rich mushroom bran feed is 5-20mg/kg. The preparation method comprises the following steps of: mixing raw materials to obtain a mixture, grinding the mixture, and then drying, grinding, sieving, mixing, grinding and conditioning the mixture. When the selenium-rich mushroom bran feed is used for cultivating the selenium-rich barley pests, barley pest larvae or pupae with high selenium content is obtained, wherein the selenium content of the selenium-rich barley pest larvae is 0.5-2.0mg/kg and the selenium content of the selenium-rich barley pest pupae is 0.5-1.5mg/kg. Through conversion on the selenium-rich mushroom bran by the barley pests, the pollution of mushroom sticks to environment can be effectively avoided, meanwhile the utilization rate of an inorganic selenium additive added in the mushroom sticks is enhanced and therefore, the waste of the selenium element under the condition of the shortage of selenium supply in China is avoided.
Description
Technical field
The present invention relates to a kind of rich selenium edible fungi residue feed and preparation method thereof, the invention still further relates to the method for using rich selenium edible fungi residue feed breeding selenium rich barley worm.
Background technology
Selenium is played an important role in life process, is called as life beneficial element.Selenium is the constituent of human erythrocyte glutathione peroxidase and phosphatide hydrogen peroxide glutathione peroxidase; its Main Function is participate in enzyme synthetic; the structure of Cell protection film and function exempt from over oxidation and interference, have many important physiological functions.China Shi Yigeque selenium big country, 2/3 He Dixi district, regional Wei Quexi district, China resident selenium intake wretched insufficiency.Only rely on selenium in wholefood can't meet China resident's demand, therefore developing selenium-enriched food seems particularly important.
The chemical form kind of selenium compound is a lot, complex structure.The selenium of different chemical form has different biologies to property, and life and health is produced to different impacts.Inorganic selenium hardening agent has advantages of that selenium content is high and cheap, but its biological effectiveness is low, and toxicity is larger, and between dosis toxica and requirement, scope is little, thereby is strictly limited its usage amount.Edible mushroom quality is tender, unique flavor, nutritious, inorganic selenium can be converted into Organic Selenium simultaneously.Therefore, selenium-enriched edible mushroom is one of topmost selenium-rich nutritive food of current China.Yet, be accompanied by the production of selenium-enriched edible mushroom, produce a large amount of bacterium chaffs, their overwhelming majority are discharged in the middle of environment around with the form of discarded object, to environment, have caused very large pollution.
Barley worm is the insect of TRenebrionidae, is China Novel cultivation insect newly developed, is protein sources and the grease source of very high-quality.It can using multiple eating bacterium bacterium chaff as feed resource, can effectively absorb wherein remaining nutrient component, barley worm children, adult polypide have the ability of higher orienting enriching to natural trace element simultaneously, particularly have stronger resistance to selenium and selenium rich ability.At present, substantially also do not have relevant technical staff to study rich selenium edible fungi residue feed.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of rich selenium edible fungi residue feed and preparation method thereof and the method for using rich selenium edible fungi residue feed breeding selenium rich barley worm.
For achieving the above object, first the present invention provides a kind of rich selenium edible fungi residue feed, take rich selenium bacterium chaff as primary raw material formulated, in described rich selenium edible fungi residue feed, the content of rich selenium bacterium chaff is 5 ~ 30wt% (percentage by weight), Se content in described rich selenium bacterium chaff is 50 ~ 250mg/kg, and in feed, final Se content is 5 ~ 20mg/kg.
As preferred version, wherein said rich selenium edible fungi residue feed also contains the raw material of following percentage by weight:
