Description

Technical Field

[0001] This invention belongs to the field of aquaculture technology, specifically, it relates to a method for culturing American cockroaches. Background Technology

[0002] The American cockroach is the largest insect in the Blattidae family. Adults are 31-44 mm long, reddish-brown, and have wings that extend beyond the end of the abdomen.

[0003] The American cockroach has high medicinal value, with its medicinal uses dating back thousands of years. The earliest written record can be traced back to the *Shennong Bencao Jing* (Shennong's Classic of Materia Medica), which mentions that the American cockroach "treats blood stasis, masses, chills and fever, breaks up accumulations, throat obstruction, and internal cold causing infertility." In traditional Chinese medicine, masses are palpable, tangible ailments in the abdomen, similar to solid tumors in modern medicine. Li Shizhen, in his *Compendium of Materia Medica* (Compendium of Materia Medica) of the Ming Dynasty, also described the cockroach family as having a body resembling a silkworm moth, with red markings on its abdomen and back, and wings capable of flight—a unique characteristic of the American cockroach. Traditional Chinese medicine believes that the American cockroach has effects such as promoting blood circulation and removing blood stasis, detoxifying and eliminating sores, promoting diuresis and reducing swelling, and treating stomach ailments. Modern pharmacological research shows that the American cockroach has anti-tumor, anti-liver damage, tissue repair-promoting, and immunity-enhancing effects, and its prepared medicines are used to treat burns, gastric ulcers, and liver cancer.

[0004] Given the valuable medicinal properties of the American cockroach, its farming has become a new and popular industry in recent years. How to rapidly reproduce it and produce a large number of high-quality offspring has become a current focus.

[0005] The life cycle of the American cockroach is divided into two stages: the first stage is the embryonic development period, which is completed inside the egg; the second stage is the post-embryonic development period, from hatching into a larva until sexual maturity as an adult.

[0006] The invention patent with patent number CN101427665B provides an artificial breeding method for American cockroaches. This breeding method, based on adapting to the natural growth pattern of American cockroaches, adds artificial regulation to improve and enhance various aspects such as temperature, humidity, feed, growth environment, and hatching environment, thereby shortening the growth cycle of American cockroaches, increasing the hatching rate of egg cases and the survival rate of larvae, and improving its medicinal components.

[0007] However, while the breeding method disclosed in the above patent does significantly improve the breeding cycle of American cockroaches compared to wild or small-scale farming, there is still considerable room for improvement. Furthermore, the survival rate of cockroaches using the above breeding method also has significant potential for improvement.

[0008] Furthermore, in other existing studies on the rearing of American cockroaches, nymphs and adults are typically reared under the same or different conditions. However, even with current artificial rearing techniques, it takes about six months for cockroach nymphs to develop into adults, a relatively long growth cycle. Throughout the entire nymphal growth period, there are significant differences in the intestinal digestive physiology and development of cockroach nymphs. Summary of the Invention

[0009] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide a method for breeding American cockroaches. This method involves feeding American cockroach nymphs under different conditions in different stages and using a new feed formula to meet the needs of the nymphs at different growth stages, improve their digestive and absorptive functions at different growth stages, shorten the breeding cycle, and improve the survival rate, breeding efficiency and medicinal quality of the products.

[0010] To achieve the above objectives, the solution adopted by the present invention is as follows:

[0011] A method for raising American cockroaches includes: (1) feeding young nymphs: newly hatched nymphs are raised in a rearing box for 30-40 days using the first feed to obtain young nymphs; by weight, the first feed includes: 30-36 parts of basic food, 4-5 parts of compound acid-base feed, and 1.2-1.8 parts of compound Chinese herbal medicine; (2) feeding older nymphs: young nymphs are raised in a rearing box using the second feed until they become adults; by weight, the second feed includes: 30-36 parts of basic food, 2-3 parts of compound acid-base feed, and 4-6 parts of compound Chinese herbal medicine.

[0012] The beneficial effects of the American cockroach farming method provided by this invention are:

[0013] (1) The digestive system of American cockroach nymphs at different growth stages has different processing capabilities, especially their digestive enzymes, including total intestinal protease, total amylase and total lipase, which are secreted in small amounts in the early stages of cockroach growth. The American cockroach breeding method provided by this invention is the first to specifically raise American cockroach nymphs under different conditions in different stages to meet the physiological needs of cockroach nymphs at different growth stages, thereby specifically improving their digestive and absorptive functions at different growth stages, shortening the breeding cycle, and improving the survival rate, breeding efficiency and medicinal quality of cockroach products.

[0014] (2) The American cockroach breeding method provided by the present invention consists of a basic feed, a compound acid-base feed and a compound Chinese herbal medicine at different stages. In this application, the raw materials in the above system are used to form a compound feed, which can synergistically enhance each other. This not only improves the digestive and absorption capacity of the cockroach nymphs, but also promotes the conversion of nutrients in the feed, improves the feed utilization rate, and avoids the cockroach from generating too much oil during its growth.

[0015] (3) The method for raising American cockroaches provided by this invention adjusts the feed formula ratio for cockroach nymphs at different growth stages, in order to focus on increasing the secretion of digestive enzymes in young nymphs, and while increasing the secretion of digestive enzymes in older nymphs, control the formation of oil, thereby improving the digestive and absorption capacity of American cockroach nymphs throughout the entire growth cycle, while reducing the cost of degreasing in the later stage, shortening the breeding cycle, and improving the medicinal value. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0017] The following is a detailed description of a method for cultivating American cockroaches provided by an embodiment of the present invention.

[0018] A method for cultivating American cockroaches includes:

[0019] (1) Feeding young nymphs: Newly hatched nymphs are fed in a breeding box for 30-40 days using the first feed to obtain young nymphs; the ratio of the amount of the first feed to the mass of the nymphs is 1-2:100; by weight, the first feed includes: 30-36 parts of basic feed, 4-5 parts of compound acid-base feed, and 1.2-1.8 parts of compound Chinese herbal medicine; the breeding temperature is 28-29℃, the relative humidity is 68-72%, and natural light is used. The first feed is mixed with water at a mass ratio of 1:1, steamed and cooled to 28-30℃, cut into small pieces or powder, and placed on each breeding rack.

[0020] The digestive system of young nymphs is not fully developed, and they can only secrete a limited amount of digestive enzymes. In addition, their bodies are relatively fragile. In this embodiment, by using the above-mentioned feeding conditions in combination, it is not only beneficial to improve the secretion of digestive enzymes in young nymphs and increase their absorption of various nutrients in the feed, but also to improve their adaptability to the feeding environment, strengthen their bodies, and promote their growth and development.

[0021] (2) Feeding of older nymphs: The younger nymphs are fed with the second feed in the rearing box until they become adults. The ratio of the amount of the second feed to the weight of the younger nymphs is 4-5:100. The second feed consists of 30-36 parts of basic feed, 2-3 parts of compound acid-base feed, and 4-6 parts of compound Chinese herbal medicine. The rearing temperature is 30-31℃, the relative humidity is 73-75%, and the light is natural. The second feed is mixed with water at a weight ratio of 1:1, steamed and cooled to 28-30℃, cut into small pieces or powder, and placed on each rearing rack.

[0022] Compared to younger nymphs, older nymphs have a better-developed digestive system and can secrete more digestive enzymes. At the same time, their absorption of various nutrients in the feed is also enhanced. In this embodiment, by using the above-mentioned feeding conditions in combination, it is still beneficial to improve the digestive and absorptive capacity of older nymphs, increase their absorption of various nutrients in the feed, and at the same time, reduce the synthesis of oil while improving their absorption of various nutrients in the feed. It can also improve their adaptability to the feeding environment, enhance their physical condition, and promote growth and development.

[0023] In this embodiment, by weight, the basic grains include: 30-45 parts corn, 20-35 parts wheat, 4-12 parts rice bran, 8-15 parts soybean meal, 2-8 parts fish meal, and 1-7 parts cicada pupae; the compound acid-base feed includes: 20-24 parts organic acid biomass (by weight, 2-4 parts sea buckthorn leaf powder, 2-4 parts lemon leaf powder, and 1-3 parts grapefruit peel powder), 3-5 parts phosphoric acid, and 0.8-1.6 parts sodium bicarbonate; the compound traditional Chinese medicine includes: 1-3 parts red yeast rice residue, 1-3 parts tartary buckwheat powder, and 1-3 parts Shenqu (a traditional Chinese medicine formula).

[0024] To enable cockroach nymphs to further absorb and digest the feed, the solid raw materials in the first or second feed are washed, dried, and then crushed and added as feed ingredients after passing through a 40-60 mesh sieve.

[0025] The first and second feeds provided in this embodiment are adjustments made according to the specific technical solution of this embodiment, which are intended to improve the digestive and absorptive capacity of cockroach nymphs at different stages of their growth and development.

[0026] For the American cockroach breeding steps not mentioned in this embodiment, please refer to the parts mentioned in patent number CN101427665B, patent titled "Artificial Breeding Method of American Cockroach".
