Abstract

The invention provides a feed additive for improving digestion and absorption functions of fish. The additive is made from the following raw materials in parts by weight: 0.1-0.5 part of calceolarioside B, 10-15 parts of a corn silk extract, 15-30 parts of dry brewer's grains, 1-5 parts of soybean lecithin, 1-10 parts of magnesium oxide, and 1-5 parts of potassium diformate. The feed additive forimproving digestion and absorption functions of fish of the invention can effectively improve the digestion and absorption functions of fish by adding soybean lecithin, calceolarioside B, the corn silk extract, dry brewer's grains, magnesium oxide, and potassium diformate.

Description

technical field [0001] The invention belongs to the field of fish farming, and in particular relates to a feed additive method for improving the digestion and absorption function of fish. Background technique [0002] With the continuous improvement of people's living standards, the consumption of fish and other aquatic products is also increasing. Fishmeal and soybean meal are high-quality protein sources for aquaculture animals. In recent years, with the rapid development of aquaculture, the demand for feed has increased year by year, resulting in tight supply and demand of high-quality protein sources and high prices, seriously restricting the sustainable development of aquaculture. Finding high-quality, cheap and abundant protein sources has become an important way to solve this problem. Contents of the invention [0003] In view of this, the present invention aims to overcome the defective in the prior art, proposes a kind of feed additive that improves fish digesti...
