Description

Compound feed for improving oxidation resistance and disease resistance of carps
Technical Field
The invention belongs to the field of aquaculture, and particularly relates to a compound feed for improving the oxidation resistance and disease resistance of carps.
Background
Carp, named as carp seed and carp raisin, is a omnivorous freshwater fish which is rich in high-quality protein, has the amino acid variety of more than ten, comprises eight essential amino acids for human body, has the human body digestibility of 96 percent, and can relieve arteriosclerosis and coronary heart disease. The carp has low fat content, proper calcium-phosphorus ratio and low price, and can meet the requirements of consumers.
Carp as one of the most important economic freshwater fishes creates great economic benefit for aquaculture industry in Europe and Asia. The total yield of freshwater fish culture in 2021 years is 2640 ten thousand tons, wherein the total yield of carps is about 283 ten thousand tons. With the rapid development of aquaculture industry, intensive culture mode is adopted for carp culture. However, intensive cultivation methods bring high economic benefits, reduce the growth performance of the cultivated fishes, cause economic losses, increase the risk of infectious diseases, and lead to mass death of the cultivated fishes, thereby limiting the development of aquaculture industry.
To avoid this, many farms abuse antibiotics for disease control and prevention. However, abuse of antibiotics can lead to the development of resistant strains that are detrimental to ecosystem and human health. For the sustainable development of aquaculture industry, an additive which can not only avoid the harm to the aquaculture water area, but also promote the health of the cultured fishes and improve the growth performance is needed. Researches find that the disease resistance and the immune response can be enhanced by adding the antioxidant into the aquatic feed, the aquaculture yield is improved, and the sustainable development is realized.
Coenzyme Q10 is the only endogenously synthesized lipid-soluble antioxidant that occurs naturally in the biological system of the inner mitochondrial membrane and plays a crucial role in the Electron Transport Chain (ETC) and energy synthesis (ATP). Coenzyme Q10 is mainly present in humans, birds and fish and plays an important role in cellular metabolism and oxidative balance. Coenzyme Q10 has both oxidized and reduced forms, and only the reduced form has antioxidant effect, and can scavenge free radicals, protect DNA, cell membrane, lipid and protein from risk of oxidative damage, help vitamin E regeneration, and maintain healthy energy level. Coenzyme Q10 is not naturally formed in animals in sufficient quantities and needs to be provided from an external source. Therefore, exogenous supplementation of this super vitamin in fish feed is suggested. In addition, the solubility of coenzyme Q10 in lipid and organic solvents and the water insolubility make the coenzyme Q10 an ideal additive for aquatic animal feed.
