Embodiment Construction

[0006] Weigh 40kg β-glucan, 18kg A3α-peptidoglycan, 27kg vitamin C-2 polyphosphate, 14.8kg vitamin E, 0.2kg ethoxyquinoline, wherein β-glucan and A3α-peptidoglycan are Powder formed after spray drying. Mix these 5 kinds of materials evenly to get the prawn compound immune enhancer of the present invention. It enhances the resistance to viral diseases caused by white spot virus and Torah virus by improving the non-specific immunity of prawns; experiments have shown that the use of this compound immune enhancement in the whole cycle of Chinese prawns, Penaeus monodon and Penaeus vannamei agent, the survival rates were increased by 25-31%, 18-25%, and 22-26%.

Abstract

A composite immunopotentiator for prawn is prepared from beta-glucosan, A3 alpha-peptidoglycan, VC-2-polyphosphate, VE and ethoxyquinoline in a certain proportion. It can prevent the negative feedback suppression of prawn organism.

Description

technical field [0001] The invention relates to a feed additive, in particular to a compound immune enhancer for prawns. technical background [0002] Due to problems such as drug residues and bacterial resistance, there is an increasing call to limit the use of antibiotics internationally. Improving the immunity of aquatic animals by adding immune enhancers to the feed can reduce the use of antibiotics. There have been many reports on the application of single-component immune enhancers in aquatic products at home and abroad, but the existing single-component immune enhancers not only have limited effects and unstable effects, but also often cause negative feedback in long-term use in aquaculture. Suppression problem. Contents of the invention [0003] The purpose of the present invention is to provide a kind of composite immune booster for prawns, which can overcome the above-mentioned shortcomings of the existing single-component immune booster. [0004] A compound i...
