Compound feed with low content of fish meal for epinephelus coioides

Abstract

The invention discloses a compound feed with low content of fish meal for epinephelus coioides, and relates to the technical field of fish feeds. The compound feed consists of the following components in parts by weight: 12 to 18 parts of fish meal, 28 to 40 parts of casein, 7 to 10 parts of gelatin, 2 to 4 parts of fish oil, 2 to 4 parts of soybean oil, 1 to 3 parts of granulesten, 8 to 35 parts of corn starch, 1 to 2 parts of monocalcium phosphate, 0.2 to 0.6 part of compound vitamin premix, 0.2 to 0.6 part of compound trace element premix, 0.3 to 0.8 part of taurine, 1 to 2 parts of sodium alginate, 0.1 to 0.3 part of choline chloride, 2 to 12 parts of zeolite powder, and 2 to 12 parts of microcrystalline cellulose powder; the raw materials are crushed, screened, mixed and granulated, so as to prepare the compound feed for the epinephelus coioides. The compound feed has the advantages that the obtaining of raw materials is easy, the nutrients are balanced, the processing is simple and convenient, the usage ratio and amount of fish meal in the feed for the epinephelus coioide are reduced, the cost is low, and the compound feed is suitable for industrialized popularization.

Description

technical field [0001] The invention relates to the technical field of fish feed, in particular to a low-fishmeal compound feed for grouper. Background technique [0002] Grouper is an important marine fish cultured in my country. In the past ten years, the grouper aquaculture industry has developed very rapidly. As of 2014, the grouper aquaculture output in mainland China reached 88,130 tons (2015 China Fishery Yearbook). It ranks fourth in the production of aquaculture. However, there is a clear contrast between the rapidly developing grouper aquaculture industry and the serious lag in research and development of grouper artificial compound feed products and the serious shortage of use. At present, grouper farming still relies heavily on chilled trash fish, with an annual consumption of about 400,000 tons, accounting for 10% of the national aquaculture chilled trash fish consumption, while the proportion of grouper cultured with compound feed is less than 10%. The main re...

Problems solved by technology

[0013] The above-mentioned technical scheme mainly highlights the technical characteristics such as the regulation of intestinal health, liver protection and immune promotion of grouper, and solves the deficiencies of the existing technology to a certain extent. There are many species of fish, and there are great differences in feeding habits and nutritional requirements of different species. The specificity of the compound feed is not strong, and the accuracy of the formula needs to be further improved. It is necessary to develop a high-efficiency compound feed suitable for different species of grouper

In addition, the proportion of fishmeal used in the prior art is generally high. In order to reduce the proportion of fishmeal used, some technical solutions have complex formulas and use some unconventional raw materials, which are not easy to obtain. Some technical solutions require more complicated operations and process, the operability in production is not strong, and the cost is also high, which is not conducive to industrialization promotion

[0014] Slanted grouper is a kind of grouper that has been cultured earlier in my country and has a higher breeding yield. There has been no report on the compound feed for its culture. Based on this, it is particularly necessary to invent a low-fishmeal compound feed for slanted grouper
