Abstract

The invention provides feeds special for crawfish. The feeds are mainly prepared from the following components in parts by weight: 5 parts of bacillus subtilis liquid, 20 to 40 parts of soybean cakes, 30 to 60 parts of corns, 25 to 45 parts of wheat bran, 10 to 20 parts of gastrodia elata, 15 to 25 parts of cortex acanthopanacis, 5 to 15 parts of astragalus, 12 to 24 parts of safflowers, 18 to 26 parts of rhizoma corydalis, 10 to 20 parts of remote lemongrass herb, 1 to 5 parts of salt, 2 to 8 parts of squid powder, 0.2 to 0.6 part of zinc-amino acid chelate and 0.2 to 0.8 part of methionine. The invention further provides a preparation method for the feeds special for crawfish. Compared with the prior art, the obtained feeds special for crawfish have the advantages that the food uptake and digestion of crawfish can be promoted, the breeding of harmful germs can be suppressed, the feeds are nutrient-rich, the growth of crawfish can be remarkably promoted, and the survivability of crawfish can be improved.

Description

technical field [0001] The invention relates to an aquatic feed, in particular to a nutrient-rich special feed for crayfish. Background technique [0002] Since the middle and late 1970s, the development of my country's feed industry has experienced three stages of emerging, growth, and adjustment, and a complete feed industry research, production, promotion, and sales system has been initially established, and remarkable achievements have been made. . my country's feed industry has developed rapidly, and feed production has increased rapidly, which has greatly enriched the market supply of feed. my country has become the world's second largest feed producer, second only to the United States. In the past ten years, the output of my country's feed products has developed steadily, the quality has been steadily improved, the structure has become more reasonable, and the overall level has continued to improve. However, my country's feed industry still has problems such as low ...
