Abstract

The present invention discloses a feed for feeding Chinese mitten crabs. A manufacture method comprises the following steps: 1) according to the following parts by weight, raw materials are prepared:23-27 parts of corns; 13-17 parts of soybeans; 13-17 parts of flour; 18-22 parts of small fish strips; 8-12 parts of oil cake; 13-17 parts of silkworm chrysalis; 0.08-0.12 part of chitin; 4-6 parts oflysine; 2-4 parts of polyamine acid; and 0.8-1.2 of allicin; (2) a fermentation mixed liquid is prepared; 3) a raw material mixture is prepared; and 4) the raw material mixture and fermentation mixedliquid are mixed at a ratio of 20:1, and after the mixing, the materials are prepared into granules in a granulator. The feed can promote digestion and absorption of the Chinese mitten crabs, greatlyreduces incidences of the Chinese mitten crabs, and enhances resistance to immunity. A growth and survival rate of the Chinese mitten crabs reaches 99.9%, the Chinese mitten crabs are higher in nutrition values, and 98% or more of diners reflect that the Chinese mitten crabs are delicious and tender in meat quality.

Description

technical field [0001] The invention relates to a feed, in particular to a feed for feeding hairy crabs. Background technique [0002] At present, the raw materials for feeding hairy crabs are mainly corn and other auxiliary materials made into granules. The granules are sprinkled in the pond during feeding. If the hairy crabs cannot be eaten quickly, the granules will soon spread and float in the water. After a long time, The scattered raw materials deteriorate, pollute the water quality, and deteriorate the environment of the pool, resulting in low immunity during the growth of hairy crabs, leading to rampant diseases. Due to the high stocking density, the degenerated raw materials after dispersion will produce unpleasant odor and excessive ammonia gas after fermentation. Hairy crabs are kept in such a harsh environment for a long time, and their immunity is low and they are susceptible to germs. . [0003] Therefore, feeding hairy crabs with the existing feed not only h...
