Abstract

The invention discloses a feed of crabs. The feed is prepared from the following components in parts by weight: 10-15 parts of Hanayama bran, 8-12 parts of rapeseed meal, 9-13 parts of soybean meal, 5-10 parts of tubificidae powder, 15-20 parts of fish meal, 10-13 parts of middlings, 5-10 parts of yolk powder, 6-8 parts of chicken liver powder, 5-8 parts of chicken blood powder, 6-8 parts of kelp powder, 4-8 parts of elodea nuttallii leaves, 5-7 parts of vallisneria natans, 4-5 parts of myriophyllum spicatum, a proper amount of salt, and 4-5 parts of a preservative, wherein the preservative is prepared from the following components in parts by weight: 10-15 parts of sorbitol, 4-8 parts of monosaccharides, 1-5 parts of sweet potato powder, 5-8 parts of gluconic acid and 4-7 parts of natamycin. The feed is an ecological and green feed, and is capable of obviously improving the disease resistance of crabs, greatly increasing the survival rate of crabs, ensuring the high breeding speed of crabs and improving the yield of crabs when being used for feeding crabs.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a crab feed and a preparation method thereof. Background technique [0002] River crabs are delicious, nutritious, have high economic value, and are in great demand in the market. In the actual breeding process, in order to increase the output of crabs, a variety of hormone drugs are often added to the feed, while feeding management and drugs are ignored. Abuse leads to drug residues in the product, and feed with insufficient nutrition seriously hinders the growth and development of crabs, prolongs the breeding cycle, and is prone to fish killing each other, which seriously affects the breeding benefits. However, the existing feeding feeds have many diseases. The survival rate is low, the reproduction speed is slow, and the output cannot be improved. Contents of the invention [0003] The purpose of the present invention is to provide a kind of crab feed, eco-environmental...
