Compound immunopotentiator for left-eye and right-eye flounders and preparation method thereof

Abstract

The invention discloses a compound immunopotentiator for left-eye and right-eye flounders, which contains burdock oligosaccharide, chitosan, chlorogenic acid, vitamin C, vitamin E and sodium alginate, wherein every 100 parts of the compound immunopotentiator contains the following components in parts by weight: 25 to 35 parts of the burdock oligosaccharide, 20 to 30 parts of the chitosan, 15 to 25 parts of the chlorogenic acid, 5 to 15 parts of the vitamin C, 5 to 15 parts of the vitamin E and 2 to 8 parts of the sodium alginate. The compound immunopotentiator for left-eye and right-eye flounders has the advantages of good performance and only 0.1 to 1.0% of the addition amount, can prominently enhance the immunity and the disease resistance of the flounders and raise the survival rate and the growth rate, has higher immune effect than other immunopotentiators, overcomes the immunosuppression phenomenon represented after long-term use of a single product and can be used in a full period; in addition, the compound immunopotentiator for left-eye and right-eye flounders overcomes the harm to cultivated aquatic products and human body caused by chemical disinfectants and antibiotics in prior disease control techniques, and settles the problems of strong specificity and high cost in prior aquatic vaccines.

Description

technical field [0001] The invention relates to a compound immune enhancer and a preparation method thereof, in particular to a compound immune enhancer for flounder and flounder in aquaculture and a preparation method thereof. Background technique [0002] The aquaculture of flounder and flounder in my country began in the middle and late 1980s. At present, flounder and flounder such as flounder and turbot are the main species of industrial farming in northern my country. Flounder and plaice grow fast, have good meat quality and high economic value. With the vigorous development of flounder and flounder aquaculture in my country, especially the rapid growth of industrialized aquaculture, the aquaculture environment is deteriorating and the resulting diseases are becoming more and more serious, which has become a constraint to the sustainable development of flounder and flounder aquaculture. the bottleneck. [0003] In order to prevent and control the losses caused by the f...
