Abstract
The invention relates to feed, in particular to feed for mixed breeding of crabs and shrimps. The feed is prepared from the following raw materials in parts by weight: 11-42 parts of snail meat, 9-28 parts of soya bean meal, 20-30 parts of lean pork, 25-35 parts of corn flour, 5-10 parts of edible oil, 8-29 parts of rice bran, 5-21 parts of peanut meal, 6-18 parts of fish meal, 5-9 parts of silkworm chrysalis, 3-9 parts of medical stone, 5-15 parts of wheat bran, 0.3-0.6 part of radix bupleuri, 0.2-0.5 part of astragalus, 1-2 parts of table salt, 5-7 parts of sugar, 0.05-0.1 part of ecdysone and 0.03-0.05 part of a mildew preventive. The feed disclosed by the invention is comprehensive and balanced in nutrition and achieves the effects of solving the problem of mismatching of the feed for mixed breeding of crabs and shrimps, improving the utilization ratio of the feed and reducing aquaculture water pollution caused by excessive feed; moreover, the feed disclosed by the invention has the effects of killing insects, inhibiting bacteria and purifying water, the survival conditions of the crabs and shrimps are improved, and the yield, quality and breeding benefits are improved.
Description
technical field [0001] The invention relates to a feed, in particular to a feed for mixed cultivation of crabs and shrimps. Background technique [0002] With the rapid development of my country's freshwater shrimp and crab aquaculture industry, the continuous expansion of the aquaculture area and production scale, the sharp increase in the aquaculture output and the continuous improvement of the degree of intensification, in order to make full use of the water body space and realize the ecological and economic benefits of the water , the implementation of shrimp and crab polyculture has been accepted by more and more farmers. Shrimp and crab polyculture mode is divided into two modes: shrimp-based and hairy crab-based. But the survival rate of shrimp is very low, and unsurviving shrimp can rot in the crab pond, which not only reduces the original economic benefits of crabs, but also brings harm to the water quality of the crab pond. [0003] Crab is a kind of aquatic produ...
