Embodiment 1

[0031] The preparation method of selenium-enriched bacterial chaff feed comprises the following steps:

[0032] (1) The chaff of selenium-enriched Pleurotus ostreatus purchased from Qingwang Selenium-enriched Edible Mushroom Farmers Professional Cooperative in Xinglong County, with a selenium content of 120-160 mg / kg, was dried at 100°C, and the dried chaff was crushed for 20 Mesh sieve;

[0033] (2) 150 g of selenium-enriched fungus chaff under the sieve is mixed with 800 g of wheat bran and 50 g of soybean meal, and then pulverized through a 30-mesh sieve;

[0034] (3) The sieved feed material is transported into the steam jacketed conditioner, fed with dry saturated steam and stirred for 100 seconds, the stirring speed is 150 rpm, the steam pressure is 0.2MPa, and the feed temperature after conditioning is at 65~75℃, the moisture content can reach 8~12wt% (weight percentage).

Embodiment 2

[0036] The method for cultivating selenium-enriched barley worm larvae (0.5 ~ 1.5mg / kg selenium content), comprises the steps:

[0037] (1) Breeding of 0-30-day-old barley larvae: the optimum temperature for breeding is 28°C-30°C, the relative humidity is 75-85%, and the density of larvae in the breeding box is 12-15 heads / cm 2 , using a feeding method that mainly concentrates and supplemented by green feed (concentrate: green feed = 1:3 (wt%)). The concentrate is the above-mentioned selenium-enriched fungus chaff feed (containing 5-7 wt% of selenium-rich fungus chaff), which can cover the bottom of the breeding box at one time, with a thickness of 2-3cm. The green material can be commercially available cabbage , potatoes, spinach and other non-legume vegetables or stems and leaves of plants, put in once every 3 days, and the amount of each feed is 10% of the weight of the concentrate;

[0038] (2) Breeding of 30-60-day-old barley larvae: the optimum temperature for breeding ...

Embodiment 3

[0041] The method of breeding selenium-enriched barley chrysalis (selenium content is 0.5~0.8mg / kg):

[0042] (1) Breed 70-day-old barley larvae fed with common feed at an ambient temperature of 25°C-27°C, a relative humidity of 65-75%, and a density of 4-6 larvae / cm in the breeding box 2 Under certain conditions, the feeding method is mainly based on concentrate and supplemented by green feed (concentrate: green feed = 1:2 (wt%)). The concentrate is the above-mentioned selenium-enriched fungus chaff feed (containing selenium-rich fungus chaff 15~17wt %), which is fed once a week, and the feeding amount is 30~40% of the insect weight. The green material can be commercially available cabbage, potatoes, spinach The stems and leaves of non-legume vegetables or plants are fed once every two days, and the feeding amount is 20-30% of the insect weight;

[0043] (2) Breed until the pupation period is approaching (the color of the worm body turns yellow, and the larvae are longer tha...

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 [0001] The invention relates to a selenium-enriched fungus chaff feed and a preparation method thereof, and also relates to a method for breeding selenium-enriched barley worms by using the selenium-enriched fungus chaff feed. Background technique [0002] Selenium plays an important role in the life process and is known as a beneficial element of life. Selenium is a component of human erythrocyte glutathione peroxidase and phospholipid hydrogen peroxide glutathione peroxidase. Its main function is to participate in the synthesis of enzymes and protect the structure and function of cell membranes from excessive oxidation and interference. , has many important physiological functions. my country is a big selenium-deficient country, two-thirds of the regions are selenium-deficient and low-selenium regions, and the selenium intake of Chinese residents is seriously insufficient. Relying solely on selenium in natural foods cannot meet the needs of Chinese reside...
