Problems solved by technology

In industrialized production, poultry manure such as chicken manure and pig manure are used as the culture medium, and the culture medium is unstable and easily mixed with harmful bacteria, which is not conducive to the production and subsequent utilization of houseflies; while housefly larvae are harmful to bran, The nutrient utilization rate of solid medium such as bean dregs is very low, and the bran after cultivating housefly larvae can no longer be eaten by other poultry and livestock, so the cost of using bran to cultivate housefly larvae is high, which is not conducive to the industrialization of housefly

Embodiment 1

[0018] Place a piece of sponge carrier (5 cm high, 80 cm long, and 40 cm wide) on the bottom of the housefly larva culture plastic tray (25 cm in height, 80 cm in length and 40 cm in length and width); Containing 8% bran, 5% whole milk powder, 5% brown sugar, 5% carrot juice; sterilized at 100°C for 20 minutes); 25°C) of Saccharomyces cerevisiae; at the same time, spread the housefly eggs evenly on the surface of the sponge block, and the inoculation amount is 40,000 eggs / square meter; at a temperature of 25-30°C, the eggs hatch into larvae; spray on the surface of the sponge block every day The above culture solution was added twice, 100ml each time, and stirred evenly.

[0019] The larvae of the housefly continue to develop and grow using the nutrients in the liquid medium. After culturing at 25-30° C. for 3 days, the housefly larvae developed into mature larvae, and the sponge block, medium and larvae were separated with a 15-mesh screen to obtain 1.48 kg of housefly larva...

Embodiment 2

[0021] Cultivate the plastic foam carrier (high 5cm, long 80cm, wide 40cm) on the bottom of the housefly larva culture plastic dish (height 25cm, length and width respectively 80cm, 40cm); Add 2L culture fluid on the plastic foam carrier in every culture dish (cultivate solution containing 5% bran, 8% whole milk powder, 6% brown sugar, 10% carrot juice; sterilized at 100°C for 20 minutes); , 25 ℃) of Bacillus licheniformis; at the same time, housefly eggs are evenly spread on the surface of the sponge block, and the inoculation amount is 40000 eggs / square meter; at a temperature of 25~30 ℃, the eggs hatch into larvae; Spray the above-mentioned culture solution twice, add 100ml each time, and stir evenly.

[0022] The larvae of the housefly continue to develop and grow using the nutrients in the liquid medium. After culturing at 25-30° C. for 3 days, the housefly larvae developed into mature larvae, and the sponge block, medium and larvae were separated with a 15-mesh screen t...

Embodiment 3

[0024] Cultivate the plastic foam carrier (high 5cm, long 80cm, wide 40cm) at the bottom of the housefly larva culture plastic dish (height 25cm, length and width respectively 80cm, 40cm); solution containing 10% bran, 10% whole milk powder, 8% brown sugar, 12% carrot juice; sterilized at 100°C for 20 minutes); , 25°C) of Enterobacter cloacae; at the same time, housefly eggs are evenly spread on the surface of the sponge block, and the inoculation amount is 40,000 eggs / square meter; at a temperature of 25~30°C, the eggs hatch into larvae; Spray the above-mentioned culture solution twice, add 100ml each time, and stir evenly.

[0025] The larvae of the housefly continue to develop and grow using the nutrients in the liquid medium. After culturing at 25-30° C. for 3 days, the housefly larvae developed into mature larvae, and the sponge block, medium and larvae were separated with a 15-mesh screen to obtain 1.56 kg of housefly larvae.

Abstract

The industrial method of culturing housefly larva includes the following steps: 1. setting adsorptive matter to the container for culturing housefly larva; 2. injecting to the adsorptive matter the liquid culture medium comprising bran 5-10 wt%, whole milk powder 5-10 wt%, brown sugar 5-8 wt%, carrot juice 5- 15 wt% and water for the rest and with probiotics; 3. spreading housefly egg to the surface of adsorptive matter and incubating the egg into housefly larva; 4. cultivating for 4-10 days; and 5. separating housefly larva with screen. The said housefly larva culturing process has high bran utilizing rate and lowered cost, and is suitable for automation of housefly larva culturing.

Description

technical field [0001] The present invention relates to the biotechnology of cultivating housefly larvae on a large scale by using culture liquid. Background technique [0002] The housefly (Musca domestica) belongs to Insecta, Diptera, Cylindrica, and Muscaidae. It is an excellent animal protein feed. It has the advantages of strong fecundity, short life cycle, easy intensive production, and abundant feed sources. It is listed as the first new protein resource in the world. The housefly is the most common and the most abundant species in most parts of our country. At present, the degree of automation of housefly breeding in my country is low, and a large amount of manpower is required for large-scale production, which restricts the industrialized utilization of housefly. [0003] The cultivation of housefly larvae is the most important stage in the production process of housefly. There are two main types of housefly larva culture medium currently used, one is poultry man...
