Problems solved by technology

Compared with fish meal, the price of fermented soybean meal is low, but the protein content of fermented soybean meal only accounts for about 55% of fish meal, and its amino acid balance is slightly inferior to that of fish meal. The proportion that can replace fish meal is limited, and it is not suitable for long-term feeding of carnivorous animals. Aquatic animals

[0087] 1. Preparation of biological feed for shrimp

[0088] 1.1 Preparation of fermented vegetable protein feed

[0089] 1.1.1 Preparation of starter

[0090] The activated Aspergillus niger (Aspergillus niger) BFEC180401 was inoculated into a 500ml Erlenmeyer flask containing 100ml of fermentation medium, and incubated at 30° C. for 24 hours, and the fermentation broth was collected to obtain Aspergillus niger seed liquor. Among them, Aspergillus niger (Aspergillus niger) BFEC180401 has been preserved in the General Microorganism Center of China Microbiological Culture Collection Management Committee, and the preservation number is CGMCC No.15990.

Abstract

The invention discloses a biology feed containing hermetia illucens larva powder, for prawns and a preparation method of the biology feed. The preparation method of the biology feed for prawns, disclosed by the invention comprises the steps of adding a fermenting agent to fermentation raw materials using soybean meal as main components to obtain a fermentation system, performing fermentation on the fermentation system, and labeling the obtained fermentation products as a fermentation plant protein feed; and mixing the fermentation protein feed with hermetia illucens to obtain the biology feedfor prawns, wherein the active component of the fermenting agent is the aspergillus niger. Experiments prove that the biology feed for prawns can increase the survival rate of the prawns, the feed coefficient can be reduced, and the biology feed has certain improvement on production properties of the prawns, can high influence on secretion of hepatopancreas digestive enzyme, can reduce the hepatopancreas damage type biochemical indicator concentration, and has good effects of promoting health of the prawns and can promoting production increasing. The biology feed for prawns is indicated to have broad application prospects.

Description

technical field [0001] The invention relates to the field of biological technology, and relates to a shrimp biological feed containing black soldier fly larvae powder and a preparation method thereof. Background technique [0002] Fish meal has high protein, balanced nutrition, high digestion and absorption rate and growth-promoting effect. It is the main protein raw material in aquatic feed. However, with the shortage of resources and rising prices, the cost of breeding will increase. Finding new alternative resources is an inevitable development trend. [0003] Soybean meal is the most important plant-based protein source for livestock and poultry. It has high crude protein content, good amino acid balance, and reasonable price. It has always been one of the most used plant-based protein sources in aquatic feed. However, if a large amount of plant protein is used in carnivorous aquatic animals, the anti-nutritional factors in plant protein will damage the intestinal epithe...
