Abstract

The invention provides a culturing method of selenium-enriched maggots, which adds selenium-enriched yeast in the seed-corn maggot feed of germ-free seed-corn maggots, and the weight ratio of the selenium-enriched yeast and the seed-corn maggot feed is 1/3-5; and selenium-enriched yeast maggot feed is put in a spawning plate of the seed-corn maggots, and the weight ratio of the selenium-enriched yeast and the seed-corn maggot feed is 1/9-11. Because the selenium-enriched yeast is added during the breeding and culturing processes of the seed-corn maggots and the maggots, the invention obtains germ-free selenium-enriched maggots containing high content of selenium, obviously improves the functional value of the maggots, and simultaneously, selenium element, protein and polysaccharide are organically integrated and transformed into bioselenium, and thereby eliminating the toxic side effect and intestines and stomach stimulation of chemical selenium, and the selenium can be more efficiently and more safely absorbed and utilized.

Description

A kind of cultural method of rich selenium fly maggot

Technical field

The present invention relates to the cultural method of a kind of insect, specifically a kind of cultural method of rich selenium fly maggot.

Background technology

Fly maggot is the comprehensive high-quality protein resource of nutrient component, contain crude protein 59%-65%, fat 2.6%-12%, 17 kinds of amino acid that animal is required, and amino acid is formed rationally, azelon is few, be easy to digest and assimilate, simultaneously, fly maggot also contains the needed trace element of multiple vital movement, it is the premium animal protein feed, also be the delicious fresh food of special economic animal, feed soft-shelled turtle, wood frog, fish, shrimp, eel, swamp eel, various birds, mink etc., growth is obviously accelerated, effect of increasing production is good, is the good feed addictive of various animals and pet, bait.Fly maggot also contains necessary other nutrient components in the sufficient amount human foods, every nutritive index is all greater than protide nutriments such as chicken, pork, beef, soft-shelled turtles, all there is the example of food fly maggot product various countries, and the existing many food companies of China are as food additives.In addition, fly maggot still is good medicinal materials.

Selenium is a kind of multi-functional life nutrient; can remove free radical, anti-oxidant, powerful generation, raise immunity, the protection biological cell membrane that suppresses lipid peroxide, strengthen the prostate regulatory function, prevent blood clot, remove cholesterol; have the effect identical, can obviously promote ability, the blood circulation of cellular uptake sugar to prevent skin aging, reduce that luring of carcinogen is carcinous, the cancer cell of eliminating vivo mutations, the division that stops cancer cell and growth etc. with insulin.Along with the reach of science, selenium more and more is familiar with by the mankind, is called as " the special effect element of life ", " life five elements ".It is 0.1mg/kg to the demand of selenium that NRC (1994) recommends poultry, and maximal tolerance dose is 2mg/kg, and scarce selenium can cause that poultry nutrition is bad, and diseases such as pancreas sex change are mended selenium and can be prevented the animal's liver disease, ensure body health, improve the animal product quality.Traditional benefit selenium method is to add the inorganic selenium of forms such as sodium selenite, sodium selenate in daily ration.Though inorganic selenium is cheap, toxicity is big, uses the difficult grasp of metering and absorb conversion ratio low.In recent years, people turn to sight on the organic selenium that toxicity is little and bioavailability is high gradually.

At present, the cultural method of fly maggot is comparatively ripe, and the further raising but the selenium content of fly maggot awaits is to increase the economic worth of fly maggot.

Summary of the invention

The cultural method that the objective of the invention is a kind of rich selenium fly maggot to improve the selenium content of fly maggot, increases its economic worth.

The technical solution adopted for the present invention to solve the technical problems is: add Se-enriched yeast in the kind fly feed of no bacterial classification fly, Se-enriched yeast is 1: 3～5 with the weight ratio of planting the fly feed; Put into the fly-maggot feed that contains Se-enriched yeast in the ovigerous disk of kind of fly, the weight ratio of Se-enriched yeast and fly-maggot feed is 1: 9～11.

Above-mentioned kind of fly feed is milk powder and brown sugar, and the weight ratio of milk powder and brown sugar is 1: 0.8～1.2.

Above-mentioned fly-maggot feed is a humidity at 60～80% moist wheat bran.

Described no bacterial classification fly is that following method obtains, the wild flies of catching is put into the fly cage, in the fly cage, be placed with food dish, water pond and ovigerous disk, the food dish is interior by putting into the fly feed, put into the water of cleaning in the water pond, placement humidity remains on 60～80% wheat bran in the ovigerous disk, move into the larvae cultivation basin with wheat bran in the ovigerous disk and ovum every day at twice, in the larvae cultivation basin, add fresh moist wheat bran every day, after 5 days pupa, with select after the pupa sterilization a big full person put into kind of a fly cage sprout wings aseptic fly kind.

Above-mentioned fly feed is milk powder and brown sugar, and the weight ratio of milk powder and brown sugar is 1: 0.8～1.2.

Beneficial effect of the present invention is: owing to added Se-enriched yeast in the cultivation of kind of fly and fly maggot, breeding process, thereby obtain the high aseptic rich selenium fly maggot of selenium content, improved the function value of fly maggot significantly, and the selenium element combines with protein, polysaccharide organic and is converted into Biological Selenium, having eliminated the toxicity of chemical selenium (as sodium selenite) and stomach stimulates, make selenium can be more efficient, more safely be absorbed and used.

Embodiment

Below the invention will be further described.

The cultural method of rich selenium fly maggot of the present invention comprises:

One, the cultivation of no bacterial classification fly

Do growth, height, wide each square fly cage of 1 meter with the crude iron silk, remove the upper strata and cover with the external application plastic gauze.Wherein one side is stayed the operation circular hole of 20 centimetres of diameters, and the cloth tube of 30 centimeter length is sewed up in the aperture, tightens at ordinary times.The wild flies of catching is put into the fly cage, places food dish, water pond, ovigerous disk in fly cage bottom, put in the food dish be by weight 1: 1 milk powder and brown sugar as the fly feed, stir, the thickness of fly feed is 4～5 centimetres; Put into the water of cleaning in the water pond; Put into humidity in the ovigerous disk and be about 70% moist wheat bran; Move into the larvae cultivation basin with the moist wheat bran in the ovigerous disk and ovum every day at twice, and adds fresh moist wheat bran every day in the larvae cultivation basin, promptly get pupa after 5 days, select after pupa is sterilized an individual big full person put into kind of a fly cage sprout wings aseptic fly kind.

Two, the breed of rich selenium fly maggot

Do growth, height, wide each square fly cage of 50 centimetres with the crude iron silk, the external application plastic gauze covers, and wherein one side is stayed the operation circular hole of 20 centimetres of diameters, and the cloth tube of 30 centimeter length is sewed up in the aperture, tightens at ordinary times.Every cage can be supported kind of fly 1～1.5 ten thousand.In kind of fly cage, place food dish, water pond, ovigerous disk, put in the food dish be by weight 1: 1 put into brown sugar and milk powder as kind of a fly feed, the thickness of planting the fly feed is 4～5 centimetres, and adds Se-enriched yeast in kind of fly feed, and Se-enriched yeast is 1: 4 with the weight ratio of planting the fly feed; Put into the water of cleaning in the water pond, ovigerous disk is put into humidity and is remained on about 70% moist wheat bran as fly-maggot feed, and the adding Se-enriched yeast, the weight ratio of the moist wheat bran of Se-enriched yeast is 1: 10, move into larvae cultivation basin and renewal with material in the ovigerous disk and ovum every day at twice; When finding that material turns black in the larvae cultivation basin, in time change or additional moist wheat bran and Se-enriched yeast, so promptly get aseptic rich selenium fly maggot.
