Health turtle additive rich in conjugated linoleic acid and preparation method thereof

Abstract

The invention relates to a feed additive for the aquaculture industry, in particular to a health turtle additive rich in conjugated linoleic acid and a preparation method thereof. The additive comprises the following components in percentage by weight: 2.5 to 5 percent of the conjugated linoleic acid, 0.25 to 0.5 percent of combination of inosine acid and guanylic acid, 1 to 1.5 percent of carnitine, 0.75 to 1.5 percent of glycine, 0.5 to 1 percent of alanine, and the balance of zeolite powder. The preparation method comprises the following steps of: firstly, crushing solid raw materials in raw materials and sifting the crushed solid raw materials with an 80-100 mesh sieve for later use; secondly, mixing and stirring the solid raw materials in proportion for later use; and finally, uniformly adding a liquid raw material namely the conjugated linoleic acid in the raw materials into the well-mixed solid raw materials to obtain the additive. The health turtle additive can effectively improve the health-care features of turtles to realize stable and high-efficiency enrichment of ClA having a plurality of biological activities in turtle muscles, and can improve the nutritive value of the turtles, the content of muscle protein of the turtles, the content of essential amino acid and the content of fresh flavor amino acid.

Description

technical field [0001] The invention relates to a feed additive for aquaculture, in particular to a health-care soft-shelled turtle rich in conjugated linoleic acid (CLA) and a preparation method thereof. Background technique [0002] In the 1980s, the artificial breeding of Chinese soft-shelled turtles developed rapidly, artificial temperature-controlled industrial high-density breeding, light-intensified greenhouse breeding and other breeding forms emerged all over the country, and even those who were eager for quick success blindly added growth-promoting hormones to the feed, which played an important role in disease prevention. Drug abuse during medical treatment. As a result, the yield of soft-shelled turtles has increased, but the quality of the products has declined. At present, there are a series of key problems in my country's soft-shelled turtle farming industry, such as poor taste, heavy earthy smell, reduced umami taste, poor color, and reduced nutritional value...

AI Technical Summary

Problems solved by technology

As a result, the yield of soft-shelled turtles has increased, but the quality of products has declined.

At present, there are a series of key problems in the soft-shelled turtle farming industry in my country, such as poor taste, heavy earthy smell, reduced umami taste, poor color and reduced nutritional value, etc. due to high density, unreasonable nutrition, environmental pollution, and short growth cycle.

At present, the biggest problem exposed in the soft-shelled turtle market is that the supply of low-grade soft-shelled soft-shelled soft-shelled soft-shelled turtles exceeds the demand, but the high-end farmed soft-shelled soft-shelled turtles and wild soft-shelled turtles are seriously out of stock.
