Description

Technical Field

[0001] The invention belongs to the technical field of feed processing, and in particular relates to an American cockroach nymph feed and a preparation method thereof. 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 stage, which is completed in the egg; the second stage is the post-embryonic development stage, from hatching as a larva to the sexual maturity of the adult. Due to the different intestinal digestive physiology and development of American cockroach nymphs and adults, American cockroach nymphs and adults are usually fed with different feeds.

[0006] The invention patent with patent number CN103262955B provides a special feed for American cockroach nymphs and a preparation method thereof, which is prepared from the following raw materials in weight ratio: 40-50 parts of corn, 10-20 parts of wheat, 8-15 parts of soybean meal, 6-10 parts of fish meal, 4-10 parts of silkworm pupae, 3-6 parts of dry yeast, 3-7 parts of rice bran, 3-5 parts of peas, 1-3 parts of white sugar, 1-2 parts of bone meal, and 0.1-0.5 parts of salt. The feed with rice can solve the technical problems of unreasonable nutritional matching and production of traditional feed formulas in large-scale breeding of American cockroaches, resulting in small feed intake and low feed conversion rate of American cockroach nymphs, which in turn leads to slow growth and high mortality.

[0007] However, the formula of the special feed for American cockroach nymphs provided in the above patent still has a large room for improvement. According to the above formula, the digestion and absorption capacity of the nymphs cannot be improved, and the accumulation of nutrients in the nymphs can only be obtained by their own continuous eating metabolism. Summary of the invention

[0008] In view of the above-mentioned deficiencies in the prior art, the first object of the present invention is to provide a nymph feed for American cockroaches, which can significantly improve the absorption and digestion of feed nutrients by cockroach nymphs through the improvement of the feed formula, thereby obtaining cockroach adults with a shorter nymph period, better growth and development, and higher nutritional value.

[0009] In view of the above-mentioned deficiencies in the prior art, the second object of the present invention is to provide a method for preparing a feed for American cockroach nymphs, which is simple to operate, is conducive to improving fertilizer efficiency, and is suitable for large-scale production.

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

[0011] A feed for American cockroach nymphs, the raw materials of which include, by weight, 30-36 parts of basic food, 1-6 parts of compound acid-base feed, and 1-7 parts of compound Chinese herbal medicine.

[0012] A method for preparing the above-mentioned American cockroach nymph feed comprises: (1) washing and drying seabuckthorn leaves, lemon leaves, grapefruit peels and bitter buckwheat, and then crushing them to obtain seabuckthorn leaf powder, lemon leaf powder, grapefruit peel powder and bitter buckwheat powder; (2) mixing and crushing seabuckthorn leaf powder, lemon leaf powder, grapefruit peel powder, Liushenqu, red yeast rice residue, bitter buckwheat powder, corn, wheat, rice bran, soybean meal, fish meal and cicada pupae by weight, and passing through a 40-60 mesh sieve, and then adding phosphoric acid and sodium bicarbonate and mixing evenly to obtain a premix; (3) adding hot water to the premix, stirring evenly, cooling to 25-30°C, and then steaming in a steamer, and then covering with a heat-insulating material and stacking at room temperature for 3-4 days to obtain the premix.

[0013] The American cockroach nymph feed and the preparation method thereof provided by the present invention have the following beneficial effects:

[0014] (1) The American cockroach nymph feed provided by the present invention comprises a basic food, a compound acid-base feed and a compound Chinese herbal medicine. The compound acid-base feed provided by the present application can promote the secretion of digestive enzymes in the digestive system of the American cockroach nymphs and improve the activity of digestive enzymes, improve the digestibility of protein and energy in the basic food by the American cockroach nymphs, form easily absorbable complexes with minerals in the basic food, improve the absorption of minerals, and can also cover up the smell of fish meal or cicada pupae; the compound Chinese herbal medicine can regulate the synthesis of fats and oils in the American cockroach nymphs after absorbing the basic food.

[0015] A new feed system can be obtained by appropriately mixing basic food, compound acid-base feed and compound Chinese herbal medicine. They work together to significantly improve the absorption and digestion of feed nutrients by cockroach nymphs, while controlling the oil content, thereby obtaining cockroach adults with shorter nymphal period, better growth and development, and higher nutritional value.

[0016] (2) The American cockroach nymph feed provided by the present invention is a composite acid-base feed obtained by mixing an organic acid, an inorganic acid and a weak base in a certain proportion.

[0017] Among them, the organic acid comes from waste biomass, which is low-cost and naturally green, and has a natural fragrance that can cover up the smell of feed and improve the palatability of feed. Specifically, in the present invention, the organic acid biomass includes a certain ratio of sea buckthorn leaf powder, lemon leaf powder and grapefruit peel powder. Among them, sea buckthorn leaf powder mainly contains organic acid and crude fat and crude fiber, lemon leaf powder mainly contains organic acid and minerals, and grapefruit peel powder is rich in vitamins and organic acids. Biomass as a source of organic acid can not only provide organic acid, but also supplement the nutrients of feed. In addition, grapefruit peel powder, due to its loose and porous structure, can also disperse the remaining raw materials to promote better absorption and utilization of the raw materials.

[0018] Compared with organic acid, inorganic acid has stronger acidity and obvious effect with less dosage. In the present invention, the composite acid composed of organic acid and inorganic acid is used, which has good buffering and biological properties, and can quickly reduce the pH value and reduce nutritional diarrhea.

[0019] The compound acid can reduce the alkalinity of animal diets by effectively providing hydrogen ions, reduce the acid-binding capacity of feeds, and increase the digestibility of feeds. At the same time, it can promote the secretion of digestive enzymes by cockroach nymphs. It is very beneficial for cockroach nymphs with insufficient gastric acid secretion, and increases the digestibility of protein and energy in feed by cockroach nymphs. It can also play an antibacterial role and reduce the occurrence of intestinal diseases. At the same time, it can promote the absorption of vitamins and minerals in feed by cockroach nymphs.

[0020] The applicant considered that adding compound acid to feed may have an adverse effect on the basic beam ion balance and the acid-base balance in the body. Therefore, sodium bicarbonate was added as a weak base to alleviate the tendency of "becoming acidic" in the body of the cockroach nymphs, thereby giving full play to the acidification effect of the compound acid. In addition, sodium bicarbonate contains sodium salt, so there is no need to add additional mineral sources such as salt to the feed.

[0021] (3) The American cockroach nymph feed provided by the present invention is a composite Chinese herbal medicine obtained by mixing red yeast rice residue, tartary buckwheat powder and Liushenqu in a certain proportion, wherein the red yeast rice residue can reduce lipids and resolve turbidity, Liushenqu can enhance gastrointestinal motility and improve intestinal flora disorder, and tartary buckwheat has the effect of lowering blood lipids. The three ingredients are mixed in a certain amount to inhibit excessive oil synthesis in the American cockroach and reduce subsequent processing costs.

[0022] (4) The method for preparing the American cockroach nymph feed provided by the present invention has a relatively simple processing process and is suitable for large-scale production. In the present invention, hot water is added to the premix, mixed and cooled, and then steamed again before being piled, which can further improve the feed fertilizer efficiency compared to the traditional preparation method.
