Feed additive for reducing freshwater fish body fat content and preparation method thereof

Abstract

The invention discloses a feed additive for reducing the freshwater fish body fat content and a preparation method thereof. The feed additive is prepared from clofibrate, soybean oil and a zeolite powder in a certain proportion. The preparation method comprises the steps: A, crushing the zeolite powder to pass through a 70-90 mesh sieve, and weighing the components of clofibrate, the soybean oil and the zeolite powder in proportion; B, mixing uniformly clofibrate and the soybean oil, then mixing uniformly with the zeolite powder in a mixing machine, and making the variation coefficient of the mixture not more than 5%, wherein the mixture is the feed additive for reducing the freshwater fish body fat content. The method is simple to implement, convenient to operate, and obvious in effect; the product with the amount of 0.5-1.5% is added into a freshwater fish feed, after feeding for 9 weeks, the freshwater fish body fat content can be significantly reduced by 16-25%, the liver fat content can be reduced by 6-11%, the abdominal fat content can be reduced by 22-35%, generation of related diseases can be effectively prevented from being induced because of excessive accumulation of the fish body fat in freshwater aquaculture, and the healthy and sustainable development of the freshwater aquaculture is promoted.

Description

technical field [0001] The invention relates to the field of feed additives for freshwater fish, in particular to a feed additive for reducing body fat content of freshwater fish, and more particularly to a preparation method of a feed additive for reducing body fat content of freshwater fish. Background technique [0002] In recent years, as the prices of protein sources such as fishmeal continue to rise, high-energy feeds have gradually become the development trend of aquatic feeds. Increasing the energy level in aquatic feed can save protein, reduce the pollution of fish body nitrogen excretion to aquaculture water, and reduce feed cost. Then, with the use of high-energy feed and the increase in feeding frequency, excessive accumulation of fish body fat will often result. This will not only cause a waste of feed resources, affect the muscle quality and flavor of freshwater fish, but also accumulate a large amount of fat in the fish body will increase its peroxidation rea...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem that the yield and quality of freshwater fish are reduced due to fat accumulation in the body of the freshwater fish proposed in the background technology, the purpose of the present invention is to provide a feed additive for reducing the body fat content of freshwater fish

The dosage of this product is small, the method is easy to operate, and the effect is remarkable. It overcomes the problems of the current lipid-lowering additives, such as unsatisfactory effects and poor pertinence. It is a new type of feed additive that regulates fat metabolism in fish from the genetic level.
