Abstract

The invention discloses a preparation method of a penaeus vannamei feed. The preparation method comprises the following steps of making bone meal, wheat flour, bean cake powder, wheat bran, potato flour, peanut cakes, soybean lecithin, animal oil, table salt, beer yeast, flavonol and a armadillidium vulgare protein extract into a first mixture, then performing vacuum sintering treatment, adding high-protein powder consisting of omphisa fuscidentalis hampson, earthworms, bean worms, diplopod and cicada pupa, adding Chinese herbal medicine filter mud, performing fermentation, performing granulation, and finally performing film forming treatment through medium and trace element microemulsion so as to obtain the penaeus vannamei feed. According to the feed prepared by the preparation method disclosed by the invention, the appetite, the food consumption and the disease resistance of penaeus vannamei are improved, and further the growth speed and the survival rate of the penaeus vannamei are increased.

Description

technical field [0001] The invention relates to the field of breeding feed, in particular to a method for preparing a feed for Penaeus vannamei. Background technique [0002] Penaeus vannamei is one of the three major economic shrimps in the world. It has the characteristics of low nutritional requirements, fast growth, strong disease resistance, wide salinity and strong adaptability. With the invention and improvement of the intensive disease-prevention breeding technology of Penaeus vannamei and the breakthrough of the artificial seed breeding technology, an upsurge of the shrimp farming industry in my country has been set off. Artificial compound feed is the material basis for healthy culture of Penaeus vannamei. Some existing aquaculture feeds are unbalanced in nutrition and poor in attracting food, which cannot improve the disease resistance of shrimp, which in turn leads to slow growth and low survival rate of Penaeus vannamei. Contents of the invention [0003] It...
