Problems solved by technology

[0003] 2. The digestive tract of aquaculture species is short, especially shrimp and crabs, and the digestive enzymes are lacking. After being eaten, the conventional feed cannot be fully digested and absorbed in the body, resulting in more than 60% of protein decomposition products. The waste nitrogen is discharged into the water, and about 53% of the phosphorus in the minerals is discharged into the water in the form of waste phosphorus. The two elements disc

Embodiment Construction

[0010] 1. Raw material screening

[0011] (1) Choose imported fishmeal, soybean meal, rapeseed meal, cotton meal and other protein raw materials, select the best combination according to different breeding objects, and mix it with various vitamins, minerals, lecithin, squid powder, and combine with refined Flour or extra flour is combined with energy raw materials to design a raw material formula that balances the needs of five major nutrients for different aquaculture targets fish, shrimp, and crabs.

[0012] (2) Select phytase, which has a strong digestion and absorption function for phosphorus, and cellulase, which has a good digestion and absorption function for aquatic animals, to prepare special enzyme preparations.

[0013] (3) Select small peptide preparations that can improve digestion and absorption.

[0014] (4) Select hydroxy iron salts and potassium aluminum sulfate which have adsorption functions for waste nitrogen and phosphorus to prepare waste nitrogen and ph...

Abstract

A nutritive mixed feed without environmental pollution for culturing aquatic animals is prepared from microecological preparation, Chinese-medicinal preparation, enzyme preparation, micropeptide preparation, and the adsorbent of waste N and P. It has high effect to clean water, provide nutrients and prevent and treat diseases.

Description

1. Technical field [0001] The invention belongs to the field of modern agricultural technology. The purpose of the invention is to provide the aquaculture industry with a compound feed that can not only meet the comprehensive needs of the breeding objects for nutrients, but also avoid water pollution and maintain a good ecological environment of the water body. 2. Background technology [0002] 1. my country's aquaculture industry has become an important pillar industry in agriculture. The development of aquaculture plays an extremely important role in supporting "agriculture, rural areas and farmers", increasing farmers' income, meeting people's demand for high-quality protein and highly unsaturated fatty acids, improving people's health, and enriching the vegetable basket project. However, as the basis for the development of the aquaculture industry, the status quo of aquatic feed has the serious defects of unbalanced nutrition, low digestion and absorption rate, and poll...
