Animal extracts are made from animal bodies or animal tissues or organs by extraction and boiling with mild enzyme, then concentrated and spray dried into meat extracts. They are a new industry that corresponds to plant extracts. Formerly, they are commonly used as raw products and biochemical raw materials. Its main categories are: amino acids, peptides, proteins, enzymes and coenzymes, polysaccharides, lipids, nucleic acids and their derivatives. The biggest characteristic is that it can dissolve into water. Natural chicken extract, natural pork extract, natural beef extract, natural seafood extract. There are many kinds of seafood, such as shrimp, oyster, abalone, squid, tilapia, crab and so on.

First, build a good yellow, muddy pool
The ponds that feed yellow trout and muddy should choose to use a cement pool or earthen pond in a sheltered, sunny area where the water source is convenient, or in cages, ponds, gutters, and rivers. The size of the area is generally 20 to 100 square meters, too big to manage. If cement ponds are used for raising earthworms and earthworms, debasing treatment must be carried out before releasing the seedlings, in order to store yellow seedlings and muddy seedlings. If earthworms are used to raise earthworms and mud, the soil is hard and the bottom of the pond must be compacted. The shape of the rearing pond is determined by the topography. The square can be round, the pool is 0.7-1 meters deep. Whether it is a cement pond or an earth pond, it must be filled with a mud layer at the bottom of the pond, 30 cm thick, containing the organic matter. More fertilizer is better, and it is beneficial for the scutellaria and loach to dig caves. Pay attention to the installation of the inlet when building the pool, overflow, water depth is maintained at 10-15 cm. Water inlets and overflow ports are tied with bar nets to prevent yellow locust and mud lice from fleeing. About 10 days before planting, thoroughly disinfect with lime, and drain water and inject fresh water 3-4 days before planting.
Second, choose a good yellow loach, loach seedlings
Raising seedlings and loach seedlings is the key. Huangpi seedlings are best cultivated by artificial cultivation of the deep yellow or large brown cantharidin varieties, can not use variegated seedlings and untrained seedlings, but can not believe "super big bang" "Thailand big bang" . The seedlings of Scutellaria baicalensis should be 50-80 pieces per kilogram, which is too small for poor food intake and low survival rate. The stocking density is generally 1 to 1.5 kg per square meter. After 20 days of stocking, the nymphs are stocked with 1/10 of the loach seedlings, and the loach seedlings should be cultured artificially. The survival rate of artificial breeding is high.
Third, feeding compound feed
Firstly, the feed stand is installed, and the feed stand is made of wood or plastic board. The area is set according to the size of the pool and is 5 cm below the water surface. Then the seedlings of Scutellaria baicalensis should be put in the first three to six days, so that the Scutellaria baicalensis should be suitable for the environment. The feed should be fed from the 4th to the 7th day. It is best to feed the feed at around 7:00 pm every day. At this time, the feed intake of Scutellaria baicalensis is the highest. Artificial rearing of jaundice is mainly based on feed, and some pupa, locust, and mealworm are properly fed. Artificially trained jaundice, compound feeds and quail are the favorite feeds. The compound feed can use the Yangtze River brand Astragalus full-priced feed or Dajiang Group's Astragalus compound feed, and can also be self-aligned. The formula is: 21% of fishmeal, 19% of cake, 37% of energy feed, and 12% of dried fruit (dry) Minerals 1%, yeast 5%, multivitamins 2%, binder 3%. Artificially cultivated dark yellow large-spotted miao seedlings were fed with this compound feed, and the fed amount was 3-5% of the weight of the scutellaria baicalensis. Feed 1 to 2 times a day (depending on the weather and water temperature). Using the principle of timing, quantitative, 20 grams of astragalus seedlings a year can grow to 200-300 grams, high breeding efficiency. Loach in the pond is mainly eaten by the feces of the yellow crickets and the uneaten jaundice feed. The loach naturally reproduces quickly. When the ratio of the pond loach is more than 1/10, wheat bran can be fed once a day.
Fourth, feeding and management
The growth season of Huangqi and Muddy is from April to November, and the peak season is from May to September. During this period, the management must be “difficult†and “fineâ€, that is, diligent patrol pool, diligent management, and finding problems to solve quickly; careful observation The growth dynamics of jaundice and loach in ponds allow timely measures to be taken. The habit of jaundice and loach is nocturnal. Keep the water in the pool fresh and the pH between pH 6.5-7.5. The water level is suitable.
V. Prevention of rickets
Take care to prevent rickets. Once the onset of jaundice, the treatment effect is often unsatisfactory. There must be no disease to prevent it first, and there must be a way to prevent it from becoming ill and prevent it from being healed. Can't believe in the lie that "Huang Xi was not sick". Frequent use of 1-2ppm bleach Quanchiposa, regular use of copper sulfate, scorpion disease, squid to stop disinfection of the whole pool to prevent disease, annual spring and autumn with crystal trichlorfon repellent, in the aphid culture pond sets Mudworms can also reduce jaundice diseases. Because muddy grasshoppers are in culture ponds, they like to move up and down, and also eat away the sundries in water bodies, which can purify water and increase oxygen.
Astragalus and loach high-yielding nesting techniques
Astragalus and loach are delicious and nutritious, and they are the best in freshwater fish. In recent years, due to artificial overfishing, pesticide poisoning, and environmental pollution, the resources of natural wild yellow locust and muddy grass have decreased, and the market is in short supply. Therefore, the development of artificial breeding of yellow earthworms and loach has broad prospects. After eight years of research and practice, the Huangqi and Muddy project team at the Mingte Fisheries Research Institute in Macheng City has used the compound feed to feed the yellow cockroach, and the yellow cockroach grows quickly and sets up the loach in the yellow cocoon breeding pond. The benefits are high, and its high-yielding farming techniques are as follows:
NMN Powder (nicotinamide mononucleotide): full name[ β- Nicotinamide mononucleotide "is a kind of naturally occurring biologically active nucleotide. The decline of NAD in aging process is considered to be the main cause of disease and disability, such as hearing and vision loss, cognitive and motor dysfunction, immune deficiency, arthritis, metabolic disorder and cardiovascular disease caused by autoimmune inflammatory reaction disorder. Therefore, NMN supplementation can increase the content of nad+ in vivo, thus delaying, improving and preventing aging related phenotypes, or age-induced metabolic disorder, aging diseases, etc. Furazolidone powder is mainly used for bacillary dysentery caused by sensitive bacteria, enteritis, cholera, typhoid, paratyphoid, giardiasis, trichomoniasis, etc. Combined with antacids and other drugs in the treatment of gastric sinusitis caused by Helicobacter pylori. Fenbendazole powder, fenbendazole is a kind of benzimidazole insecticide. It not only has high repellent activity to adults and larvae of gastrointestinal nematodes, but also has good effect on reticulum, Fasciola and cestode, and has strong insecticidal effect on eggs. Levamisole hydrochloride is an insect repellent and immunomodulator. It has good curative effect on Ascaris lumbricoides, hookworm, Enterobius vermicularis and strongyliasis faecalis. Albendazole powder is a highly effective and broad-spectrum insect repellent. It is one of the benzimidazole drugs with wide insect repellent spectrum and the strongest insecticidal effect. It can be used to expel Ascaris lumbricoides, pinworm, hookworm, whipworm, treat all kinds of cysticercosis, and also be used to expel livestock.
