Feed additive for industrial prawn aquaculture

Abstract

The invention provides a feed additive for industrial prawn aquaculture. The feed additive comprises the following components in parts by weight: 30-40 parts of shrimp shell meal, 5-20 parts of cysteamine, 1-3 parts of cellulose, 2-5 parts of lecithin, 2-5 parts of calcium carbonate, 0.1-0.5 part of phytase, 0.5-2.0 parts of bacillus, 1.0-3.0 parts of candida utilis, 0.1-0.4 part of bio-active humic acid, 0.1-0.4 part of chitosan, 0.3-0.7 part of tea polyphenol and 1.2-4.0 parts of trace element additives. The feed additive disclosed by the invention is enriched in various essential protein sources, trace elements, special mineral substances and vitamins, and the requirements on various nutritional ingredients at the growth stage in the earlier stage of the prawn aquaculture are met; and moreover, the feed additive disclosed by the invention does not have any harmful effect on palatability of a feed, prawns fed by the feed added with the feed additive is fast in growth and healthy, and high economic benefits and ecological benefits are brought to enterprises and farmers.

Description

technical field [0001] The invention belongs to the technical field of aquatic product cultivation, and in particular relates to a feed additive for industrialized cultivation of prawns. Background technique [0002] Feed additives refer to the addition of a small or trace amount of nutritive or non-nutritive substances to feed in order to improve feed utilization, ensure or improve feed quality, meet the nutritional needs of animals, promote animal growth, and ensure the health of animals. [0003] Prawns have become a common seafood on people's tables and are deeply loved by people. Feed additives are also used in the prawn farming process to obtain high quality prawns. In the 1980s and 1990s, in order to improve the level and efficiency of farming, the farming industry of various countries in the world successively used additives such as exogenous hormones or psychotropic drugs in feed and drinking water, but the residues of such drug additives are harmful to human body ...

Problems solved by technology

[0005] With the rapid development of industrialized shrimp farming, due to the unsatisfactory effect on the pollution control of the aquaculture environment, the aquaculture environment has been polluted, especially the degree of pollution of the aquaculture water body has been far greater than the purification ability of the water body itself, resulting in the pollution of the water body. The increase of ammonia nitrogen, nitrite nitrogen, phosphate, sulfide, organic matter and other pollutants will lead to serious eutrophication of the water body, destroying the normal micro-environmental ecosystem of the water body, and ultimately affecting the yield and quality of prawns
