Embodiment 1

[0030] 1. Main raw materials and tools

[0031] (1) Cow dung: Select fresh cow dung produced by yellow cattle in Yunxi District, Shiyan City, Hubei Province. The water content of cow dung in this area is 83.3%, organic matter is 77.5%, nitrogen is 20.3%, phosphorus pentoxide is 0.16%, and potassium oxide is 0.16%; Crude protein in air-dried cow dung is 11.94%, crude fiber 30.63%, crude ash 18.17%, crude fat 2.19%, nitrogen-free extract 40.90%, calcium 1.400%, and phosphorus 0.36%. The water content in the fermented cow dung is 65-75%, the crude protein content is 40-45%, the cellulose is 17-20%, the lignin is 13-19%, the hemicellulose is 5.5-6.5%, and the pH is 6-7.5 .

[0032] (2) Vitality 99 fermentation agent: purchased from Yichunqiang Microbial Technology Co., Ltd., product batch number: 2016123610.

[0033] (3) Breeding frame or three-dimensional culture pond: specifications 15-25 square meters.

[0034] (4) Breeding box: made of plastic, with a size of 60cm*40cm*25cm. ...

Embodiment 2

[0045] Basically the same as Example 1, the difference is that the preparation of the culture medium is carried out by the following method: select wet cow dung 98%, cornmeal 2%, 0.01% vitality 99 fermentation bacteria agent as the main matrix, and then mix it with water at a ratio of 1:10000 Mix the ratio, adjust the humidity to 60%-70%, carry out composting and sealed fermentation, and raise the temperature from room temperature to 38.3°C within 30 hours, then continue to raise the temperature, raise the temperature to 42.4°C through 62 hours, and then use 85 hours to lower the temperature The temperature was lowered to 38.5°C, and the temperature was stably kept above 36.5°C for 49 hours to complete the fermentation process. This fermentation time is 9.41 days and 226 hours in total.

Abstract

The invention discloses a method for breeding grubs with fermented cow dung, and belongs to the technical field of grub breeding. The method for breeding the grubs comprises the steps of culture medium preparation, egg breeding, egg collecting, staging breeding, grub adult cultivation and the like. The cow dung is selected for breeding the grubs on a large scale, the breeding method is simple, convenient to use and low in cost, animal waste is utilized, pollution to the environment can be reduced, and remarkable economic benefits can be achieved. According to the method, the breeding density,the breeding condition, breeding feed preparation and grub screening and separating are studied, and the grubs can be bred intensively.

Description

technical field [0001] The invention relates to the technical field of grub cultivation, in particular to a method for cultivating grubs by using fermented cow dung. Background technique [0002] Grub, also known as the white star beetle, belongs to the superfamily of beetles and the subfamily of beetles. Its larvae are scavenging and can use animal feces. Traditional Chinese medicine believes that it has the effects of breaking blood and removing blood stasis, improving eyesight, etc. Pharmacological studies have shown that its tea has the functions of constricting blood vessels, anti-tumor, resisting and protecting the liver, etc. According to related reports, grubs are rich in fatty acids , amino acid polypeptides or, protein, sugars, alkaloids and other nutrients, so grubs are not only used as medicinal insects, but also excellent feed raw materials with high economic value. The research results show that grubs are not limited by regional climate conditions. It has the ...
