Embodiment Construction

[0006] Weigh 35kg β-glucan, 15kg A3α-peptidoglycan, 15kg vitamin C-2-polyphosphate, 15kg levamisole, 10kg ginsenoside, 10kg vitamin E. Mixing these 6 kinds of materials evenly is the compound immune enhancer for grouper of the present invention. It enhances the resistance to diseases caused by bacteria and viruses by improving the immunity of the grouper.

[0007] From 2005 to 2006, experiments in Guangdong and Hainan showed that the grouper feed coefficient was reduced by 18.7% and 19.1%, respectively, and the survival rate was 18.7% and 19.1% lower than that of the control group, respectively, when the compound immune enhancer was used in the whole cycle of grouper inshore cage culture. An increase of 21.9% and 25.0% (Table 1).

Abstract

The invention relates to a composite immunity intensifier for groupers, which comprises the following components according to weight percentage: 30 to 40 percent of Beta-dextran, 10 to 20 percent of A3 Alpha peptidoglycan, 10 to 20 percent of vitamin C-2- polyphosphate ester, 10 to 20 percent of levomisole, 5 to 10 percent of ginsenoside and 5 to 10 percent of vitamin E. The invention has the advantages that: firstly, the composite immunity intensifier effectively overcomes the problem that the body reverse feedback of the groupers is restrained and can be used in the whole culturing period of the groupers; secondly, the composite immunity intensifier as a feed additive is used in the compound feed of the groupers and only has 0.1 to 0.2 percent of addition amount; thirdly, the body immunity of the groupers is intensified obviously and the survival rate is improved; fourthly, the composite immunity intensifier has no bad effect on the palatability of feed; and fifthly, the raw material used by the composite immunity intensifier has stable source, low price and simple production process.

Description

technical field [0001] The invention relates to a feed additive, in particular to a compound immune enhancer for grouper. technical background [0002] Grouper is a warm-water offshore bottom rare fish. The meat is plump, tender, and nutritious, and is highly praised by people. Live fish is sold in Hong Kong and Macao markets, and is regarded as a first-class delicacy, and the supply exceeds demand. It is expensive and has high economic value. At present, it has become a kind of mariculture fish with important economic value in southern my country. In order to improve the survival rate of breeding, it is often necessary to use antibiotics in the breeding process. Due to problems such as drug residues and bacterial resistance, there is an increasing call to limit the use of antibiotics internationally. If the immunity of aquatic animals is improved by adding immune enhancers to the feed, the use of antibiotics in the breeding process can be reduced or even eliminated. Th...
