Problems solved by technology

High additions can easily cause sugar metabolism problems in crustaceans; low additions lead to poor stability in feed water and high dissolution rate; 2. In the formula, high plant protein content is beneficial to improve the stability of feed water, but plant protein often It has disadvantages such as poor palatability, unbalanced amino acid content, low digestibility and anti-nutritional factors, and long-term use will lead to growth inhibition of aquatic animals
High-quality fishmeal is the best animal protein source in crustacean feed. However, due to the lack of fi

Abstract

The invention particularly relates to application of clostridium autoethanogenum protein in crustacean feed, and belongs to the field of feed, and the application is as follows: the clostridium autoethanogenum protein is used as a protein source for producing the crustacean feed, and the crustacean feed comprises Chinese prawn feed and river crab feed. According to the crustacean feed prepared by taking the clostridium autoethanogenum protein as the protein source provided by the embodiment of the invention, the dosage of animal/vegetable protein raw materials in the feed can be reduced without influencing the growth performance of crustaceans. Protein raw materials serve as essential nutrient sources of crustaceans, and the protein content, palatability and digestibility of the protein raw materials become important indexes for measuring the quality of the raw materials; the dosage of fish meal/vegetable protein in the formula can be reduced without influencing the growth performance; the stability of the feed in water is improved, and the dissolution rate of the feed is reduced; and the feed cost is reduced and the breeding income is increased.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to the application of ethanol Clostridium protein in crustacean feed. Background technique [0002] Crustaceans generally feed on benthic small animals and plants. Chinese prawns are mainly distributed in the Yellow Sea and the western coast of North Korea. They are the main products exported by my country's aquatic products. At present, my country's prawn aquaculture production has been carried out from Dandong City, Liaoning in the north to the coast of Hainan in the south. The annual output of aquaculture is about 200,000 tons, which greatly exceeds the catch in natural sea areas. River crab is the freshwater crab with the largest output in my country. Crab meat has the advantages of high protein content, low carbohydrate content, rich in various amino acids and vitamins. River crabs not only have high requirements for nutrient content and palatability in the feed, but also have ...
