Description

Compound feed preparation for enhancing body color and immunity of Chinese soft-shelled turtles, feed containing compound feed preparation and application of compound feed preparation
Technical Field
The invention belongs to the field of feed preparations, particularly relates to a feed preparation for enhancing body color and immunity of Chinese soft-shelled turtles, and also relates to a feed containing the feed preparation and application thereof.
Background
The Chinese soft-shelled turtle is an important economic variety for aquiculture in China, and has rich nutritional value, medicinal value, ornamental value and economic value. With the rapid development of economy and the improvement of the living standard of consumers, the demand of people on the yield and the quality of the Chinese soft-shelled turtles is higher and higher, the increasing demand of consumption cannot be met only by wild soft-shelled turtle resources, and the high-quality demand cannot be met by the traditional breeding mode. Under the background of pursuing high yield, the domestic breeding mode of the Chinese softshell turtles, whether greenhouse breeding or external pond breeding, is mainly high-density; in addition, the quality consciousness and brand consciousness of the Chinese soft-shelled turtle culture production are thin, so that the quality of the product is mixed, the image of the Chinese soft-shelled turtle food is damaged, the price of the Chinese soft-shelled turtle is lowered, and the culture economic benefit is landslide. The method has the advantages of improving the body color of the Chinese soft-shelled turtle, improving the product quality of the Chinese soft-shelled turtle, strengthening the immune function of the Chinese soft-shelled turtle, reducing the application of medicaments for preventing and treating diseases, meeting the production requirements of organic agricultural products and being a research hotspot of the current aquaculture. Therefore, the research and development of the green, environment-friendly, efficient, pollution-free and residue-free feed immunopotentiator and body color enhancer for the Chinese soft-shelled turtles are particularly important, so that the harm of diseases to the Chinese soft-shelled turtles is reduced, and the healthy development of the breeding industry of the Chinese soft-shelled turtles is guaranteed.
The large processed products of shrimps in China are mostly frozen headless shrimps and frozen shrimp meat, so a large amount of leftovers such as shrimp heads, shrimp shells and the like are generated in the processing process, and due to the restriction of the processing industry, a large amount of leftovers cannot be effectively utilized in a value-added manner. The processing byproducts such as the shrimp heads and the like have comprehensive and high content of protein and amino acid, are rich in DHA, EPA, astaxanthin and various mineral elements, can be directly absorbed and quickly decomposed by partial components, and have high digestibility and bioavailability. Therefore, the shrimp processing by-product is a high-quality feed raw material after being processed and utilized. At present, common utilization ways of leftovers such as shrimp heads and the like mainly comprise: (1) as a raw material for preparing chitin; (2) processing to obtain shrimp shell powder feed.
Crustacean shells are the most important commercial source of chitin. At present, chitin has potential application in agriculture, food, medical treatment, biological medicine industry and the like. The leftovers such as the shrimp heads, the shrimp shells and the like are processed into the shrimp shell powder through the working procedures of high-temperature cooking, disinfection and sterilization, drying, sieving and the like, and the shrimp shell powder generally contains abundant chitin, astaxanthin cholesterol, calcium, phosphorus, iron, manganese and other beneficial elements. A large number of tests report that the shrimp shell powder can improve the palatability of the feed, provide protein for animals, not only has good food calling effect, but also can enhance the disease resistance of the animals, promote growth, and improve the body color and the product flavor.
The Chinese herbal medicine is treasure in China, has long-term source and has application history for thousands of years, and has a series of characteristics of wide source, various types, good effect, low cost, no drug resistance, no residue, no toxic or side effect, no environment pollution and the like. The Chinese herbal medicine not only has direct inhibition and killing effects on pathogenic microorganisms, but also can enhance the disease resistance of organisms by mobilizing the anti-stress capability of the organisms, improving the immunity and defense functions of the organisms, and in recent years, the Chinese herbal medicine is widely applied to aquatic animal culture as an additive, and the application of the Chinese herbal medicine in aspects of growth promotion, disease control and the like in Chinese soft-shelled turtle culture is reported.
In the disease prevention and treatment of the Chinese soft-shelled turtles, a method of adding chemicals into feed is generally adopted, which easily causes the diseases of the Chinese soft-shelled turtles, increases the death rate and causes the loss of cultivation. Therefore, there is a need to develop a green and healthy feed preparation for enhancing the body color and improving the immunity of the Chinese soft-shelled turtles.

The Chinese herbal medicine extract is prepared by uniformly mixing astragalus, acanthopanax, honeysuckle, wild chrysanthemum, liquorice, houttuynia, poplar flower, hawthorn, purslane and dandelion in the same weight ratio, decocting and drying. The preparation method comprises the following steps of taking radix astragali, acanthopanax, honeysuckle, wild chrysanthemum, liquorice, houttuynia cordata, poplar flower, hawthorn, purslane and dandelion according to the same weight ratio, mixing uniformly, adding water which is 8-10 times of the total weight of the medicines, soaking for 30-60 minutes until the water is soaked, covering and decocting, boiling with strong fire, decocting with slow fire for 60-80 minutes after boiling, cooling, removing medicine residues, and performing spray drying on the obtained medicine liquid by taking starch which is 3-4 times of the weight of the medicine liquid as a carrier to prepare the traditional Chinese medicine powder.
The shrimp shell powder is prepared by using leftovers of crawfish after processing as raw materials, cleaning, sterilizing, drying, and crushing by using a 500-mesh nano crusher. Preferably, the temperature for disinfection and sterilization is 120-135 ℃, and the time is 0.5-1 hour; the drying is to dry for 1.5 to 2 hours at the temperature of 50 to 80 ℃ by steam; the leftovers include shrimp head, shrimp shell, etc.
The obtained shrimp shell powder mainly contains: oligochitosan, astaxanthin, phospholipid, long-chain polyunsaturated fatty acid, 19 amino acids (threonine, valine, methionine, isoleucine, leucine, phenylalanine, lysine, histidine, arginine, glycine, cystine, tyrosine, aspartic acid, serine, glutamic acid, proline, alanine, tryptophan and taurine) and 8 trace elements (calcium, phosphorus, iron, zinc, sodium, potassium, magnesium and sulfur). Because the chitosan molecule has amino, hydroxyl and other groups, many metal ions can be chelated by hydrogen bonds, and therefore, the metal ions in the solution can be effectively adsorbed and separated. Not only can remove macromolecular substances in Chinese medicinal extract, but also can trap heavy metal ions, so that the heavy metal content can be reduced, and the quality of medicine and product can be improved. The oligosaccharide can be combined with effective components of Chinese medicinal materials to form chitosan composite medicinal film, and has antibacterial and antiviral effects.
