Embodiment 1

[0014] Penaeus vannamei feed during the ovipositing stage, the feed ingredients and parts by weight are: 12 parts of fish meal, 20 parts of fermented peanut meal, 3 parts of fish oil, 2 parts of soybean lecithin oil, 40 parts of flour, 0.1 part of choline chloride, 0.8 parts of brewer's yeast part, bile salt 0.1 part. The preparation of the feed includes the following steps:

[0015] 1) Activation culture: first inoculate Bacillus subtilis on the slant medium in an aseptic manner, and culture at 29°C for 2 days. The components and parts by weight of the slant medium are: 0.2 parts of beef extract, 1 part of peptone, sodium chloride 0.4 parts, 2 parts of agar, 90 parts of water; then pick 1 ring of bacteria from the slant culture medium and put it into the liquid activation medium, shake it at 32°C and 170r / min for 6h, the components and weight parts of the liquid activation medium are : 1.4 parts of beef extract, 5 parts of peptone, 2.4 parts of sodium chloride, 400 parts of ...

Embodiment 2

[0019] Penaeus vannamei feed during the ovipositing stage, the feed ingredients and parts by weight are: 16 parts of fish meal, 24 parts of fermented peanut meal, 5 parts of fish oil, 5 parts of soybean lecithin oil, 45 parts of flour, 0.3 parts of choline chloride, 1.2 parts of brewer's yeast part, bile salt 0.2 part. The preparation of the feed includes the following steps: first, inoculate Bacillus subtilis on the slant medium in an aseptic manner, and cultivate it at 33°C for 3 days. 0.7 parts of sodium chloride, 3 parts of agar, 95 parts of water; then pick 2 rings of bacteria from the slant culture medium and insert them into the liquid activation medium, shake and culture at 37°C and 180r / min for 7h, the composition and weight of the liquid activation medium The parts are: 2.5 parts of beef extract, 7 parts of peptone, 3.5 parts of sodium chloride, and 450 parts of water. The Bacillus subtilis used was purchased from China Agricultural Microorganism Culture Collection ...

Abstract

The invention discloses a feed for penaeus vannamei at an oogenesis period. The feed comprises the components in parts by weight: 12-16 parts of fish meal, 20-24 parts of fermentation peanut meal, 3-5 parts of fish oil, 2-5 parts of soybean phospholipid oil, 40-45 parts of flour, 0.1-0.3 part of choline chloride, 0.8-1.2 parts of beer yeast, and 0.1-0.2 part of bile salt. The feed has the beneficial effects that bacillus subtilis is used for performing fermentation treatment on the peanut meal, so that various antigenic components and anti-nutrition factors in the peanut meal are effectively reduced and removed, protein in the peanut meal is also decomposed into a great quantity of small peptides, and the small peptides free from antigen are easy to absorb by the penaeus vannamei, so that the oogenesis quantity of the penaeus vannamei can be notably increased; and besides, remaining of the feed in water bodies is reduced, so that the content of ammonia nitrogen in the water bodies is reduced, and environment-friendly requirements are met.

Description

technical field [0001] The invention relates to the field of aquatic feed, in particular to a feed for Penaeus vannamei in the ovipositing stage. Background technique [0002] Penaeus vannamei belongs to the prawn family, and its scientific name is Litopenaeus vannamei. It is one of the three species with the highest production of farmed shrimp in the world. Penaeus vannamei has a thin shell and fat body, fresh and tender meat, with a meat yield as high as 65%, rich in nutrition, and is popular in domestic and foreign markets; the growth speed is fast, and it can reach the market specification in 60 days; the suitable salt range is wide (0-40% ), can adopt pure fresh water, brackish water, and seawater a variety of breeding modes, and can grow from natural sea areas to freshwater ponds, thus breaking the geographical restrictions, and has high temperature resistance and strong disease resistance. It is a high-quality variety and is a cultured shrimp with great development p...
