Problems solved by technology

Domestically, the loss of these vitamins is usually increased by increasing the amount of vitamins added, which not only cannot make up for the loss well, but also increases the cost.

preparation example Construction

[0032] The preparation method of described shrimp compound premix, it may further comprise the steps:

[0033] 1) material preparation: prepare various raw materials by the substance composition and the proportioning ratio of the shrimp compound premix described in claim 1, will select the material with poor water absorption, good fluidity, need not be dried;

[0034] 2) Pre-treatment of raw materials: raw materials should be dehydrated, dried and pulverized, including secondary powder, limestone powder and the pulverization of major elements and micro-crushing of trace elements; some micro-materials with strong water absorption need to be dried and then pulverized, The crushing particle size is 100-300 mesh, and the particle size of the carrier limestone powder is 100 mesh;

[0035] 3) Ingredients and mixing: vitamins and minerals are weighed and fed in proportion, and mixed in the mixer. When mixing, the carrier is first put in, and then various corresponding ingredients are...

experiment example 1

[0037] Experimental Example 1: Jinnan District Aquatic Technology Extension Station of Tianjin City raised Penaeus vannamei with the premixed feed of the present invention, and simultaneously compared with the feed without masking agent, put 50,000 seedlings per mu, and through 120 days of cultivation, mu Produce 800 jins, control group yields 710 jins per mu, increase production 90 jins (increasing yield rate 11%).

experiment example 2

[0038]Experimental Example 2: Tianjin Jixian Aquatic Technology Extension Station, raised Penaeus vannamei with the premix of the present invention, and simultaneously compared with the feed without masking agent, put 40,000 seedlings per mu, and through 120 days of cultivation, the yield per mu 695 jin, the yield per mu of the control group was 620 jin, an increase of 70 jin (10.8% yield increase).

Abstract

A premixed composite feed for shrimp contains multiple vitamines, minerals, choline chloride and the ionic masking agent for preventing the suppression of some metallic ions to digestive enzyme. It can increase the growth speed of shrimp and the utilization rate of feed and improve water quality.

Description

technical field [0001] The invention relates to a shrimp premix, in particular to the shrimp premix prepared by using a masking agent, which is applied to the cultivation and production of shrimp. Background technique [0002] In the production of prawns, the input of bait accounts for about 50-60% of the cost of prawns, and the additives play a role in supplementing nutrition in the bait, improving the immunity and stress of the body, improving the quality of aquatic products, and regulating the metabolic process of the body. Its role is self-evident. Many metal ions are trace elements necessary for the growth and development of animals. But these metal ions, especially Cu 2+ Heavy metal ions, such as heavy metal ions, combine with the active groups of digestive enzymes after ingestion, thereby greatly reducing the activity of digestive enzymes, reducing their ability to decompose proteins, fats, carbohydrates and other nutrients, and ultimately affecting the utilization ...
