Problems solved by technology

[0006] 1. The processing cost is high and the risk of biological safety is high. It is necessary to crush the sick and dead animals. The gaps in the culture material for breeding fly maggots are reduced, which reduces the supply of oxygen for the growth of fly maggots, and the output is low. At the same time, it is not easy to carry out biological safety control.
[0007] 2. The auxiliary materials are wheat bran and sugar, the cost is too high
[0008] 3. The temperature requirement of the treatment process is high, it needs to reach 136°C, which consumes a lot of energy
[0011] 1. The processing technology of this patented method is complex and costly, and the fly maggots need to be squeezed and separated from the fly maggot oil
[0012] 2. The growth of fly maggots requires corresponding culture substrates, which mainly provide the oxygen needed for growth of fly maggots, and the materials are required to be fluffy. The effect of directly using sick and dead livestock and poultry to raise fly maggots is poor

Embodiment 1

[0046] A method for ecological treatment of dead pig fly maggots, comprising the steps of:

[0047] A. Preparation of feed for sick and dead pigs

[0048] The collected dead pigs were soaked in boiling water for 60 minutes, cooled to 30°C, and the dead pig feed and fungus chaff were prepared to make the dead pig culture material for breeding fly maggots, and placed in the fly maggot breeding box for waiting. use;

[0049] B. Preparation of Lucilia sericata eggs and larvae

[0050] Take Lucilia sericata ovum from the kind of fly culture cage, cover 1cm thick with bacterium chaff, hatch out the fly maggot larva for subsequent use;

[0051] C. Cultivation of fly maggots with culture material of sick and dead pigs

[0052] According to the weight ratio of 10g Lucilia sericata hatched maggots to 5 kg sick and dead pig feed, the hatched maggot larvae were inoculated on the dead pig culture feed, the maggot breeding box was placed in the maggot breeding room, and the room temperat...

Embodiment 2

[0056] A method for ecological treatment of dead pig fly maggots, comprising the steps of:

[0057] A. Preparation of feed for sick and dead pigs

[0058] The collected dead pigs were soaked in boiling water for 120 minutes, cooled to 30°C, and the dead pig feed and fungus chaff were prepared to make the dead pig culture material for breeding fly maggots, and placed in the fly maggot breeding box stand-by;

[0059] B. Preparation of Lucilia sericata eggs and larvae

[0060] Take Lucilia sericata ovum from the kind of fly culture cage, cover 1cm thick with bacterium chaff, hatch out the fly maggot larva for subsequent use;

[0061] C. Cultivation of fly maggots with culture material of sick and dead pigs

[0062] According to the calculation of the weight ratio of 5 kg of sick and dead pig feed processed by 20 g of Lucilia sericata eggs hatched maggots, the hatched maggot larvae were inoculated on the sick and dead pig culture material, and the maggot breeding box was placed...

Embodiment 3

[0066] A method for ecological treatment of dead pig fly maggots, comprising the steps of:

[0067] A. Preparation of feed for sick and dead pigs

[0068] The collected dead pigs were soaked in boiling water for 90 minutes, cooled to 30°C, and the dead pig feed and fungus chaff were made into the dead pig culture material for breeding fly maggots, and placed in the fly maggot breeding box stand-by;

[0069] B. Preparation of Lucilia sericata eggs and larvae

[0070] Take Lucilia sericata ovum from the kind of fly culture cage, cover 1cm thick with bacterium chaff, hatch out the fly maggot larva for subsequent use;

[0071] C. Cultivation of fly maggots with culture material of sick and dead pigs

[0072] According to the calculation by weight of 15g Lucilia sericata eggs hatched maggots processing 5 kg sick and dead pig feed, the hatched maggot larvae were inoculated on the dead pig culture material, the maggot breeding box was placed in the maggot breeding room, and the ro...

Abstract

The invention provides a death pig housefly larvae ecological treatment method. The method realizes complete resource utilization of death pigs. The method comprises the following steps of immersing a death pig in boiling water, adding a proper amount of mushroom bran into the death pig to obtain a death pig culture material for housefly larvae cultivation, inoculating the death pig culture material with incubated housefly larvae according to a certain ratio, carrying out culture for 3-4 days to obtain mature housefly larvae, collecting the mature housefly larvae as a protein forage raw material, carrying out further compost fermentation on the collected residue, carrying out air drying to greatly reduce moisture, and carrying out crushing to obtain the products which can be directly used as nutrient-rich biological-organic fertilizer. The method realizes efficient and fast treatment on death pigs, has no latent biosafety problems, does not product secondary pollution, has a low investment cost and has high integrated economic benefits.

Description

technical field [0001] The invention belongs to the technical field of resources and environment, and in particular relates to an ecological treatment method for dead pig fly maggots. Background technique [0002] my country is the largest livestock production and consumption country in the world, but due to the backward concept of production technology and insufficient attention to the ecological safety of livestock, the mortality rate of livestock ranks first in the world. In 2009, there were 46.89 million breeding sows in my country, 490 million pigs in stock, and 660 million pigs were slaughtered annually, but more than 100 million non-slaughter deaths occurred in the year, accounting for about 20%. There are many reasons for the high mortality rate of livestock in our country, and one of the most important reasons is that there are too many diseases. An important reason for frequent animal diseases is that the industry treats livestock carcasses too casually. For many...
