Fermented brewer's grain feed for Litopenaeus vannamei

Abstract

The invention discloses fermented brewer's grain feed for Litopenaeus vannamei. The fermented brewer's grain feed comprises raw materials in parts by weight as follows: 50-60 parts of fermented brewer's grains, 5-10 parts of fish meal, 10-15 parts of cuttlefish paste, 4-8 parts of clam meat powder, 2-5 parts of egg powder, 2-5 parts of yeast powder, 2-5 parts of shrimp shell meal, 3-5 parts of pumpkin powder, 2-3 parts of dry honey powder, 0.5-1 part of calcium peroxide, 0.005-0.008 parts of vitamins, 1-2 parts of magnet powder, 1-1.5 parts of minerals and 1-3 parts of an additive. A preparation method of the fermented brewer's grains comprises the following steps: brewer's grains are smashed, soaked in a hydrogen peroxide solution for 3-5 h, inoculated with Trichoderma viride for aerobic fermentation for 1-2 days and inoculated with photosynthetic bacteria for anaerobic fermentation for 3-6 days, then a fermented product is soaked in a glycine solution for 2-3 days and dried, and the fermented brewer's grains are obtained. By means of the fermented brewer's grain feed, the growth speed of the Litopenaeus vannamei can be increased obviously, and the diseases resistance of the Litopenaeus vannamei can be improved obviously.

Description

technical field [0001] The invention relates to aquaculture technology. More specifically, the present invention relates to a fermented brewer's grain 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.
