Embodiment 1

[0018] The effect of embodiment 1 different ratio NaOH to leftovers alkali hydrolysis

[0019] The leftovers are processed as follows: the leftovers, alkali and water are respectively 100:2:300, 100:2.5:300, 100:3:300, 100:3.5:300, 100:4:300, 100:4.5: 300, 100:5:300, 100:5.5:300 weight ratios for alkaline hydrolysis treatment, fermented at 30°C for 25 days, and when the pH dropped to 7, it was used to prepare feed for housefly larvae.

[0020] Feed preparation and feeding methods are as follows: Weigh 1.5kg of fresh wheat bran and 6.5kg of leftovers from alkaline hydrolysis fermentation, mix them evenly, put them into plastic boxes of 68cm×45cm×18cm, and then receive 55,000 eggs of housefly in each box, Breed at a temperature of 26°C and a humidity of 60%. After 4 days, the larvae were separated from the compost, and the weight of the separated larvae and the weight of a single larvae were weighed. Repeat 6 times. The control was fed with 100% fresh wheat bran (2.5kg of fre...

Embodiment 2

[0024] Embodiment 2: the influence of water on the alkaline hydrolysis effect of leftovers

[0025] The leftovers are processed as follows: the leftovers, alkali and water are respectively 100:4:150, 100:4:200, 100:4:250, 100:4:300, 100:4:350, 100:4: The weight ratio of 400 is subjected to alkaline hydrolysis treatment, and fermented at 30° C. for 25 days. When the pH drops to 7, it is used to prepare feed for housefly larvae.

[0026] Feed preparation and feeding methods are as follows: Weigh 1.5kg of fresh wheat bran and 6.5kg of leftovers from alkaline hydrolysis fermentation, mix them evenly, put them into plastic boxes of 68cm×45cm×18cm, and then receive 55,000 eggs of housefly in each box, Breed at a temperature of 26°C and a humidity of 60%. After 4 days, the larvae were separated from the compost, and the weight of the separated larvae and the weight of a single larvae were weighed. Repeat 6 times. The control was fed with 100% fresh wheat bran (2.5kg of fresh whea...

Embodiment 3

[0030] Embodiment 3: the influence of temperature on the fermentation of leftovers of alkaline hydrolysis

[0031] The leftovers are processed as follows: the leftovers, alkali and water are subjected to alkaline hydrolysis treatment in a weight ratio of 100:4:300, and they are respectively placed at 13, 18, 23, 28, 33, 38, and 43°C for fermentation until the pH drops At 7 o'clock, prepare housefly larvae feed.

[0032] Feed preparation and feeding methods are as follows: Weigh 1.5kg of fresh wheat bran and 6.5kg of leftovers from alkaline hydrolysis fermentation, mix them evenly, put them into plastic boxes of 68cm×45cm×18cm, and then receive 55,000 eggs of housefly in each box, Breed at a temperature of 26°C and a humidity of 60%. After 4 days, the larvae were separated from the compost, and the weight of the larvae, the weight of each larvae and the survival rate of the larvae were measured. The results are shown in Table 3.

Abstract

The invention belongs to the artificial feeding field of insects, and particularly relates to a method for refeeding fly maggots with leftovers of wheat bran after being utilized for the cultivation of housefly larvae. The method comprises the following steps: performing alkaline hydrolysis and fermentation on the leftovers of wheat bran after being utilized for the cultivation of the housefly larvae, blending with fresh wheat bran in a certain proportion to prepare a housefly larvae compost for breeding the housefly larvae. According to the method, the recycling of the leftovers is fully realized, the application amount of the wheat bran during the production process of the fly maggots is greatly reduced, and the cost of raw materials is reduced by two to three times. The method provides powerful technical support for utilizing the wheat bran to breed the fly maggots cleanly with a low cost.

Description

technical field [0001] The invention belongs to the field of artificial breeding of insects, and in particular relates to a method for raising fly maggots by using leftovers after breeding housefly larvae with wheat bran. Background technique [0002] Housefly larvae can be reared in culture materials such as animal manure, rice bran, milk powder, distiller's grains and wheat bran. Wheat bran is characterized by its large yield, convenient handling and no parasitic mites. Therefore, since Richardson (1932) reported the artificial breeding of houseflies, it has become the main material for raising housefly larvae. However, the protein utilization rate of housefly larvae to wheat bran is very low, generally less than 50%. Therefore, the crude protein content of leftovers after feeding fly maggots can still reach 7-8% (the crude protein content of wheat bran without feeding housefly larvae Protein is about 13%), but these leftovers cannot continue to be used to raise housefly...
