Description

Technical Field

[0001] The invention belongs to the technical field of breeding, and in particular relates to a breeding method for American cockroaches. Background Art

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

[0003] The American cockroach has a high medicinal value and has a history of thousands of years of medical treatment. The earliest documented record can be traced back to the "Shennong Bencao Jing", which mentions the American cockroach: "It is used to treat blood stasis, hard masses, cold and heat, break up accumulation, throat and pharynx closure, and internal cold and infertility." In traditional Chinese medicine, accumulation of masses is a disease that is seen in the abdomen and has a shape that can be felt by hand, similar to the solid tumor in modern medicine. In the Ming Dynasty, Li Shizhen also described the medicinal animals of the Blattidae family in the "Compendium of Materia Medica" as "the body is like a silkworm moth, the abdomen and back are red, and the two wings can fly", which is exactly the unique feature of the American cockroach. Traditional Chinese medicine believes that the American cockroach has the effects of promoting blood circulation and dispersing blood stasis, detoxifying and eliminating malnutrition, diuresis and swelling, and treating stomach diseases. Modern pharmacological studies have shown that the American cockroach has anti-tumor, anti-liver damage, promoting tissue repair, and improving immunity. Its finished drug preparations are used to treat burns, gastric ulcers, liver cancer, etc.

[0004] Based on the precious medicinal value of American cockroaches, breeding of American cockroaches has become a new hot industry in recent years. How to make them reproduce quickly and produce a large number of high-quality offspring has become a hot topic.

[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 as a larva to sexual maturity as an adult.

[0006] The invention patent with patent number CN101427665B provides an artificial breeding method for American cockroaches. The breeding method is artificially regulated on the basis of adapting to the natural growth law of American cockroaches, and is improved and enhanced in various aspects such as temperature, humidity, feed, growth environment and hatching environment, thereby shortening the growth cycle of American cockroaches, improving the hatching rate of egg sheaths and the survival rate of larvae of American cockroaches, and improving their medicinal components.

[0007] However, the breeding method disclosed in the above patent does have a significant improvement in the breeding cycle of American cockroaches compared to those raised in the wild or by individual farmers, but there is still much room for improvement. In addition, the survival rate of cockroaches also has a lot of room for improvement using the above breeding method.

[0008] In addition, in other prior art studies on the breeding of American cockroaches, cockroach nymphs and cockroach adults are usually raised under the same or different conditions. However, even with current artificial breeding technology, it takes about half a year to breed cockroach nymphs into cockroach adults, and the growth cycle is relatively long. During the entire growth period of cockroach nymphs, 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 deficiencies in the prior art, the object of the present invention is to provide a method for breeding American cockroaches, in which the American cockroach nymphs are raised under different conditions in stages and a new feed formula is adopted to meet the needs of the cockroach nymphs at different growth stages, improve their digestion and absorption functions at different growth stages, shorten the breeding cycle, and improve the survival rate of cockroaches, breeding efficiency and medicinal quality of the product.

[0010] In order to achieve the above object, the solution adopted by the present invention is:

[0011] A method for breeding American cockroaches comprises: (1) feeding young nymphs: using a first feed to breed newly hatched nymphs in a breeding box for 30-40 days to obtain young nymphs; the first feed comprises, by weight, 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 old nymphs: using a second feed to breed young nymphs in a breeding box until adults are obtained; the second feed comprises, by weight, 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 breeding method of American cockroaches provided by the present invention are:

[0013] (1) The processing capacity of the digestive system of American cockroach nymphs at different growth stages is different, especially the secretion amount of digestive enzymes, including total intestinal protease, total amylase and total lipase, is relatively small in the early stage of the cockroach. The breeding method of the American cockroach provided by the present invention is the first to specifically breed the American cockroach nymphs under different conditions in different stages to meet the physiological needs of the cockroach nymphs at different growth stages, thereby specifically improving the digestion and absorption function of the cockroach nymphs at different growth stages, shortening the breeding cycle, and improving the survival rate of the cockroach, breeding efficiency and medicinal quality of the product.

[0014] (2) The breeding method of the American cockroach provided by the present invention comprises feeds for different stages consisting of basic grains, compound acid-base feeds and compound Chinese herbal medicines. In the present application, the raw materials in the above system are used for combination, which can synergize with each other, not only improving the digestion and absorption capacity of the cockroach nymphs themselves, but also promoting the conversion of nutrients in the feed, improving the feed utilization rate, and preventing the cockroach from generating excessive oil during the growth process.

[0015] (3) The breeding method of the American cockroach provided by the present invention adjusts the formula ratio of the feed according to the cockroach nymphs at different growth stages, so as to achieve the purpose of focusing on improving the secretion of digestive enzymes in the young nymphs at the early stage, and controlling the formation of fat while improving the secretion of digestive enzymes in the old nymphs, thereby improving the digestion and absorption capacity of the American cockroach nymphs throughout the entire growth cycle, while reducing the cost of fat removal in the later stage, shortening the breeding cycle, and improving the medicinal value. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be described clearly and completely below. If the specific conditions are not specified in the embodiments, they are carried out according to conventional conditions or conditions recommended by the manufacturer. If the manufacturer of the reagents or instruments used is not specified, they are all conventional products that can be purchased commercially.

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

[0018] A method for cultivating American cockroaches comprises:

[0019] (1) Feeding of young nymphs: Use the first feed to feed the newly hatched nymphs in a breeding box for 30-40 days to obtain young nymphs; the mass ratio of the first feed to the nymphs is 1-2:100; in terms of 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; the breeding temperature is 28-29°C, the relative humidity is 68-72%, and the environment is natural light. The first feed is mixed with water in a mass ratio of 1:1, steamed in a steamer, cooled to 28-30°C, cut into small pieces or powdered, and placed on each breeding rack.

[0020] The digestive system of young nymphs is not fully developed, the digestive enzymes that can be secreted are limited, and their physique is relatively fragile. In this embodiment, the above-mentioned feeding conditions are used in conjunction with each other, which is not only conducive to improving the secretion of digestive enzymes in young nymphs and increasing their absorption of various nutrients in the feed, but also can improve their adaptability to the feeding environment, enhance their physique, and facilitate their growth and development.

[0021] (2) Feeding of older nymphs: Use the second feed to continue raising younger nymphs in the breeding box until they become adults; the mass ratio of the second feed to the younger nymphs is 4-5:100; in terms of 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; the breeding temperature is 30-31°C, the relative humidity is 73-75%, and the environment is natural light. The second feed is mixed with water in a mass ratio of 1:1, steamed in a steamer, cooled to 28-30°C, cut into small pieces or powdered, and placed on each breeding rack.

[0022] Compared with younger nymphs, the digestive system of older nymphs is relatively well developed and can secrete more digestive enzymes, but at the same time, their absorption of various nutrients in the feed will be enhanced. In this embodiment, the above-mentioned feeding conditions are used in conjunction with each other, which is still beneficial to improving the digestion and absorption capacity of older nymphs and increasing their absorption of various nutrients in the feed. At the same time, it is expected to improve their absorption of various nutrients in the feed while reducing the synthesis of oils and fats, and can also improve their adaptability to the feeding environment, enhance their physical fitness, and facilitate their growth and development.

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

[0024] In order to make the cockroach nymphs further absorb and digest the feed, the solid raw materials in the first feed or the second feed are washed, dried, crushed and sieved through a 40-60 mesh sieve before being added as feed raw materials.

[0025] The first feed and the second feed provided in this embodiment are adjustments made according to the specific technical solution of this embodiment, and are intended to improve the digestion and absorption capacity of the cockroach nymphs according to the growth and development characteristics of the cockroach nymphs at different stages.

[0026] The American cockroach breeding steps not mentioned in this embodiment can refer to the part mentioned in the patent number CN101427665B, and the patent name is the artificial breeding method of American cockroach.
