Complex immunity enhancing agent for colossoma brachypomum fry breeding

[0010] Example 1

[0011] A compound immune enhancer for freshwater pomfret seedlings, used as a feed additive for freshwater pomfret seedlings. When the water temperature of the breeding pond is above 15°C, the dissolved oxygen content of the seedling pond is kept> 5mg / ml during the seedling raising process. Start adding after days, and add 0.3% in the feed until the end of seedling raising;

[0012] The compound immune enhancer is composed of the following raw materials by weight: 18 parts of peptidoglycan, 18 parts of chitin, 14 parts of glycyrrhizin, 6 parts of vitamin C, and vitamin B 2 5 parts, 8 parts of lactoferrin, 10 parts of Grifola frondosa extract, 10 parts of Ganoderma lucidum polysaccharide, 5 parts of Cypress fungus polysaccharide, 4 parts of Sophora japonica extract, 2 parts of Epimedium extract.

[0013] Statistic about the emergence of seedlings, the average seedling size is 23.5mm, and the survival rate is 84.5%.

[0014] Example 2

[0015] A compound immune enhancer for freshwater pomfret seedlings, used as a feed additive for freshwater pomfret seedlings. When the water temperature of the breeding pond is above 12°C, the dissolved oxygen content of the seedling pond is kept> 5mg / ml during the seedling raising process. Start adding after days, and add 0.4% in the feed until the end of seedling raising;

[0016] The compound immune enhancer is composed of the following raw materials by weight: 24 parts of peptidoglycan, 16 parts of chitin, 12 parts of glycyrrhizin, 7 parts of vitamin C, and vitamin B 2 4 parts, 5 parts of lactoferrin, 8 parts of Grifola frondosa extract, 10 parts of Ganoderma lucidum polysaccharide, 6 parts of Cypress fungus polysaccharide, 5 parts of Sophora japonica extract, 3 parts of Epimedium extract.

[0017] According to statistics of emergence, the average emergence size is 21.8mm, and the survival rate is 85.3%.

[0018] Example 3

[0019] A compound immune enhancer for freshwater white pomfret seedlings, used as a feed additive for freshwater white pomfret seedlings. When the temperature of the water in the breeding pond is above 20℃, the dissolved oxygen content of the seedling pond is kept> 5 mg / ml during the seedling raising process. Start adding after days, and add 0.2% in the feed until the end of seedling raising;

[0020] The compound immune enhancer is composed of the following raw materials by weight: 20 parts of peptidoglycan, 14 parts of chitin, 15 parts of glycyrrhizin, 8 parts of vitamin C, and vitamin B 2 5 parts, 6 parts of lactoferrin, 12 parts of Grifola frondosa extract, 6 parts of Ganoderma lucidum polysaccharide, 8 parts of Cypress fungus polysaccharide, 4 parts of Sophora japonica extract, 2 parts of Epimedium extract.

[0021] According to statistics of emergence, the average emergence size is 22.6mm, and the survival rate is 86.4%.
