Embodiment 1

[0030] A golden pomfret young seedling feed formula, comprising the following components by weight:

[0031] 20 parts of fish meal, 30 parts of soybean meal, 20 parts of high-gluten flour, 5 parts of squid paste, 3 parts of yeast powder, 12 parts of CMC, 4 parts of fish oil, 0.5 parts of magnolia alkali, 2 parts of agaricus blazei polysaccharide, 2 parts of fermented herb 1 part, 1 part of calcium dihydrogen phosphate, 0.5 part of lutein.

[0032] The fermented product of Huangzicao is prepared through the following steps:

[0033] S1. Take the whole herb of Hainan Huangzicao, wash it, dry and pulverize it into powder, and mix the dried Huangzicao powder and the Lactobacillus liquid to obtain a pre-fermented mixture (add 3-5 mL of Lactobacillus liquid per gram of Huangdicao dry powder); Wherein, the Lactobacillus bacterium liquid is obtained by inoculating Lactobacillus delbrueckii subsp. 7 CFU / mL;

[0034] S2. Fermentation treatment of the pre-fermented mixture obtained in...

Abstract

The invention discloses a feed formula for trachinotus ovatus at the fry stage. The feed formula comprises the following components: fish meal, soybean meal, high-gluten flour, squid visceral ointment, yeast powder, carboxymethyl cellulose (CMC), fish oil, 0.5-1.0 parts by weight of magnoflorine, 2-3 parts by weight of agaricus blazei murill polysaccharide, 2-5 parts by weight of fermented acanthaceae championella tetrasperma, monocalcium phosphate and xanthophyll. The feed formula disclosed by the invention is suitable for the trachinotus ovatus at the fry stage; the feed contains functionalcomponents including the magnoflorine, the agaricus blazei murill polysaccharide, the fermented acanthaceae championella tetrasperma and the like; through the synergistic effect of all the components,the survival rate of fries reaches 95%-98%, -98%, the specific growth rate reaches 3.1%-6.2%, and the infection death rate is as low as 8.2%-3.5% after the trachinotus ovatus is fed with the feed for60 days. The raw materials of the feed formula are easy to obtain, the preparation method is simple, and the feed formula is easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a golden pomfret feed formula at the seedling stage. Background technique [0002] Golden pomfret (Trachinotus ovatus) belongs to the class Teleost, Perciformes, Trevalidae, and the genus Pomfret. The fish is tender and delicious. It is one of the famous and valuable marine economic fish in the south. Now the coastal areas of Guangdong, Guangxi, Hainan and Fujian are the main producing areas of golden pomfret. At present, there are many feed formulas dedicated to golden pomfret, but there are relatively few feed formulas for the young seedling stage, and most of them are for the purpose of meeting nutritional needs, and few feed formulas can effectively improve the disease resistance of fish fry. Along with the golden pomfret breeding scale increases year by year, golden pomfret disease is also more and more, has influenced the development of golden pomfret breeding ind...
