Anti-stress feed for Procambarus clarkii and production method for anti-stress feed

Abstract

The invention discloses an anti-stress feed for Procambarus clarkii and a production method for the anti-stress feed. The feed comprises a cottonseed meal enzymolysis product, a water extract of full honeysuckle and a dried yeast culture in a weight ratio of (4-6):(1-1.5):(0.05-0.1). The anti-stress feed for the Procambarus clarkii according to the formula can remarkably improve growth performance, survival rate and stress resistance of shrimps; the palatability of the feed is improved; the shrimps are a nuisanceless environment-friendly food after eating the feed; and the feed improves economic benefits for feed producers and farmers, and is favorable for the sustainable development of the fishery.

Description

technical field [0001] The invention belongs to the technical field of aquatic product compound feed, and relates to a crayfish anti-stress feed and a production method thereof. Background technique [0002] Crayfish (Procambarus clarkii) belongs to the class Crustacea, the subclass Mollusca, the order Decapod, and the family Crayfish. Because the image is similar to the lobster in the deep sea and the individual is small, it is often called "crayfish". Because of its delicious meat, rich nutrition, and high protein content, it is favored by consumers and has great potential in the international market. It is an excellent variety for my country's export to earn foreign exchange. In recent years, the natural resources of crayfish have decreased sharply, and the natural growth has been transformed into artificial breeding, and the scale of breeding is getting larger and larger, and the demand for artificial feed is becoming more and more urgent. But at present, it mainly fee...

AI Technical Summary

Problems solved by technology

However, artificial compound feeds are rarely used. Even the artificial compound feeds used are not specially designed for the nutritional characteristics of lobsters. They are all replaced by other shrimp and crab feeds, resulting in unbalanced nutrient intake of crayfish in the breeding process. , lead to slow growth of shrimp body, low disease resistance and reduced meat quality, etc. These problems all affect and restrict the large-scale and healthy farming of crayfish in my country

There are few domestic research reports on the nutrient requirements of crayfish, and there is a lack of basic data on the nutrient requirements of crayfish, and there is no uniform standard to follow

In addition, most of the relevant foreign researches were carried out in the 1990s, and due to the differences in breeding models and feed material varieties, the nutrient levels of the research results vary widely or the results are contradictory, so it is difficult to compare and analyze the research results in the actual breeding process. Low referenceability, unable to adapt to the current farming status in my country
