Compound feed low in carbon for adult anguilla rostrata and preparation method of compound feed

Abstract

The invention discloses a compound feed low in carbon for adult anguilla rostrata. The compound feed comprises the following components in parts by weight: 15-35 parts of hermetia illucens powder, 10-15 parts of clamworm powder, 10-15 parts of powder of a mixture of one or more of pheretima aspergillum(E.Perrier),pheretima guillelmi (Michaelsen),pheretima vulgaris Clen and pheretima pectinifera Michaelsen, 4-8 parts of powder of a mixture of one or more of achatina fulica, helix aspersa and cathaica, 4-8 parts of imported white fish powder, 3-5 parts of fly larva powder, 3-5 parts of bombyx mori linnaeus powder, 3-5 parts of yellow mealworm powder, 3-5 parts of vital wheat gluten, 3-5 parts of whey powder, 2-4 parts of sweet potato flour, 2-4 parts of corn flour, 2-4 parts of strong flour,2-4 parts of soybean flour, 1-2 parts of entermorpha dried marine algae powder, 1 part of yeast powder, 1 part of soybean lecithin, 1 part of multiple vitamins, 1 part of multiple minerals, 0.2-0.4 part of methionine, 0.2-0.4 part of glutamic acid and 0.1-0.2 part of choline. Worm protein is used for replacing fish meal protein, so that the cost is reduced, the mouth feel of the adult anguilla rostrata can also be improved, the taste bud of the adult anguilla rostrata can be stimulated, and the growth rate of the adult anguilla rostrata is increased; and the worm protein also has the effect of improving immunity, and besides, the substances of marine algae polysaccharide and the like are added, so that the corresponding disease resistance and the inverse resistance are achieved, and further the disease resistance of the adult anguilla rostrata is strengthened, and the survival rate of the adult anguilla rostrata is increased.

Description

technical field [0001] The invention relates to the field of compound feed for aquaculture animals, in particular to a low-carbon American eel compound feed and a preparation method thereof. Background technique [0002] American eel (Anguilla rostrata), one of 18 species of eels in the order Anguilla, belongs to the family Anguillaidae. It is a fish of high economic value that is native to the east coast of North America and migrates through rivers. Eel is rich in a variety of nutrients, which have the functions of tonifying deficiency and nourishing blood, removing dampness, and anti-tuberculosis. It is a good nutrient for patients with chronic illness, weakness, anemia, and tuberculosis. In recent years, farming has also been gradually carried out in some areas in the south, and the scale has gradually expanded. [0003] There have been some studies on the requirements of American eel for protein, fat (including essential fatty acids), vitamins, and trace elements, but h...

AI Technical Summary

Problems solved by technology

[0003] There have been some studies on the requirements of American eel for protein, fat (including essential fatty acids), vitamins, and trace elements, but high-efficiency, low-cost, and high-quality artificial compound feeds have not yet been developed, and the compound feeds sold in the market still mainly rely on white fish meal. However, the increasingly scarce and high price of imported white fishmeal has seriously affected the development of the American eel industry, and the high residual bait of commercially available eel compound feed has caused serious water pollution, which has greatly increased the incidence of eel and affected the American eel industry.
