Embodiment Construction

[0006] Weigh 30kg β-glucan, 15kg levamisole, 15kg lentinan, 10kg vitamin A, 20kg vitamin E, 10kg methionine selenium. Mix these 6 kinds of materials evenly to get the composite immune enhancer for pomfret of the present invention. It enhances the resistance to diseases caused by bacteria and viruses by improving the immunity of Pompano ovata.

[0007] From 2005 to 2006, the experiments in Guangdong and Hainan showed that the compound immune enhancer was used in the whole cycle of offshore cage culture of pomfret ovata. Rates were increased by 22.2% and 24.3% (Table 1).

Abstract

The invention relates to a compound immunopotentiator for golden pomfrets, which comprises following ingredients by weight percentages: 20 to 30 percent of beta-dextran, 10 to 20 percent of levamisol, 10 to 20 percent of lentinan, 10 to 15 percent of vitamin A, 10 to 20 percent of vitamin E and 10 to 15 percent of selenium methionine. The invention effectively overcomes the problem of reverse feedback inhibination of golden pomfret organisms, can be used in a complete culture period of the golden pomfrets, is used as a feed additive to be added in golden pomfret feed by only 0.1 percent to 0.2 percent, obviously enhances the organism immunity of the golden pomfrets, improves the live rate, and has no influence on the palatability of the feed; and raw materials used in the compound immunopotentiator have stable resources, low cost and simple production technology.

Description

technical field [0001] The invention relates to a feed additive, in particular to a compound immune enhancer for oval pomfret. technical background [0002] Oval pomfret (Trachinotus ovatus), commonly known as golden pomfret, is a rare edible fish with tender meat and delicious taste. It is a kind of marine fish with important economic value in southern my country. Antibiotics are often required during the procedure. 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. 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...
