Problems solved by technology

Composting the gastrointestinal contents of livestock and poultry has a certain risk of pollution
After livestock and poultry are slaughtered, the discarded gastrointestinal contents still contain a large amount of undigested and absorbed protein and other nutrient species. Random discarding will pollute the environment and waste resources

Embodiment 1

[0026] (1) Effect of breeding feed formula on the output of black soldier fly larvae

[0027] By setting different ratio groups of cow stomach content and straw, the breeding method of the present invention is used to breed black soldier flies. The results showed that when the ratio of cow stomach content to straw was 9:1, the yield of black soldier fly larvae was the highest (see Table 1 for details).

[0029]

[0030] (2) The influence of breeding feed formula on the yield and composition of organic fertilizer

[0031] By setting different ratio groups of sheep stomach content and straw, the breeding method of the present invention is used to breed black soldier flies. The results showed that when the ratio of sheep stomach content to straw was 9:1, the yield of organic fertilizer was the highest (see Table 2 for details).

Embodiment 2

[0045] A method for processing the gastrointestinal contents of livestock and poultry discarded after slaughter by using black soldier flies, the specific steps comprising the following steps:

[0046] Step 1, preparation of breeding feed: 9 kg of slaughtered waste cattle gastrointestinal contents were crushed (with a crushing diameter of 10 mm) and 1 kg of crushed rice straw (the crushing diameter was 2 mm) were mixed into a material, and the water content of the material was controlled at 60%; Then 55g of Bacillus subtilis was mixed with 55g of saccharomyces to make fermented bacteria powder; finally, 100g of fermented bacteria powder was sprayed on every 10kg of material, fully mixed and placed for 48 hours as breeding feed for subsequent use;

[0047] Step 2, collection of black soldier fly eggs: place black soldier fly adults in a greenhouse with a length of 3m, a width of 3m, and a height of 3m, and place a tall plant with leaves at a height of 2m in the greenhouse as a r...

Embodiment 3

[0051] A method for processing the gastrointestinal contents of livestock and poultry discarded after slaughter by using black soldier flies, the specific steps comprising the following steps:

[0052] Step 1, breeding feed preparation: mix 9 kg of slaughtered discarded sheep gastrointestinal contents after crushing (the crushing diameter is 10 mm) with 1 kg of crushed crop stalks (the crushing diameter is 3 mm) to form a material, and the water content of the material is controlled at 55% ; Then 55g Bacillus subtilis and 55g saccharomyces are mixed to make fermented bacteria powder; finally, every 10kg of material is sprayed with 100g fermented bacteria powder, fully mixed and placed for 48 hours as a breeding feed for subsequent use;

[0053] Step 2, collection of black soldier fly eggs: place black soldier fly adults in a greenhouse with a length of 3m, a width of 3m, and a height of 3m, and place a tall plant with leaves at a height of 2m in the greenhouse as a resting plac...

Abstract

The invention relates to the technical field of biological treatment of organic garbage and feed preparation, in particular to a method for treating waste gastrointestinal contents of slaughtered livestock and poultry by using hermetia illucens. The specific preparation process comprises the steps of breeding feed preparation, hermetia illucens egg collection, hermetia illucens egg incubation and hermetia illucens larva breeding. According to the treatment method, the waste gastrointestinal contents of the slaughtered livestock and poultry and straw are used as raw materials to feed hermetia illucens larvae, the waste organic garbage can be fully utilized, and the effects of reducing pollution and protecting the environment are achieved; the waste gastrointestinal contents of the livestock and poultry are rich in nutritional ingredients such as high protein and fat, after the hermetia illucens are bred, high-protein solid feed for the hermetia illucens larvae and the hermetia illucens frass organic fertilizer can be obtained, and the additional value of the hermetia illucens is increased; and the hermetia illucens larvae are easy and convenient to breed, the period is short, the equipment investment is low, the cost is low, and the price advantage is achieved.

Description

technical field [0001] The invention relates to the technical field of organic waste biological treatment and feed preparation, in particular to a method for treating the gastrointestinal contents of slaughtered livestock and poultry by using black soldier flies. Background technique [0002] my country is a large agricultural breeding country with a long history of domestication and breeding of livestock and poultry. The slaughtering and consumption of livestock and poultry ranks among the top in the world. With the rapid development of modern animal husbandry and food processing industry, there are relatively complete disposal and utilization methods for the waste or by-products (including blood, bones, viscera, fur, etc.) produced in the slaughtering process of livestock and poultry. Intestinal contents are usually discarded as litter or piled up. Composting the gastrointestinal contents of livestock and poultry has a certain risk of pollution. After livestock and poult...
