Description
Technical field
The invention belongs to field of feed processing more particularly to a kind of feeds that cultivating river crab uses.
Background technique
River crab is shellfish, and feeding habits are very miscellaneous, under field conditions (factors) based on drinking water grass, humus, is also fond of spiral shell, freshwater mussel
Son, worm, insect also prey on small fish, shrimp once in a while, when food deprivation also can cannibalism, or even oneself the ovum of eating, general feelings
Under condition, river crab obtains plant food and comes easy, often constitutes the main ingredient of crab stomach food.It, can under the conditions of artificial breeding
According to needed for river crab growth and development, scientific feeds feed, can be conducive to the growth of river crab, since river crab economic value is high, again
It convenient for artificial breeding, therefore is one of important species of aquaculture.The feed used when the present invention is a kind of cultivating river crab, matches
The feed is made using corn, barley, rape cake, silkworm chrysalis, crab shell powder, blood meal, salt, multi-vitamins as raw material, and with specific work
Skill is formulated, and the feed nutrition is abundant, and palatability is good, after river crab is edible, is able to satisfy river crab in the nutritional need in growth period, is made
The speed of growth of river crab increases, and meat significantly improves, and disease resistance is strong, highly-safe.
Summary of the invention
Present invention mainly solves the problem of be to provide a kind of feed for river crab and its preparation method, produce the product and use raw material
Include: by weight ratio corn 40%-42%, barley 18%-20%, rape cake 18%, silkworm chrysalis 4%, crab shell powder 12%, blood meal 5.5%,
Salt 0.25%, multi-vitamins 0.25%.
The technical solution adopted by the present invention is that:
(1) corn of formula ratio, barley, rape cake, silkworm chrysalis are sent into pulverizer and crushed is powdered rear feeding blender, will be matched
The crab shell powder just measured, blood meal, salt, multi-vitamins are also fed into blender, and appropriate amount of water blending is added uniformly to obtain mixed fodder.
(2) mixed fodder feeding pelletizer is directly granulated, is then fed into drying machine drying, the temperature of dryer is 45
DEG C -50 DEG C, drying time is 1.2-1.4 hour, generally 0.01-0.02 grams again of particle, obtains feed for river crab after drying
Grain.
(3) feeding method of feed for river crab is: feed for river crab is shed in the crab pool.
Preferably, the corn is yellow maize.
Preferably, the multi-vitamins are mixed by the vitamin B1, vitamin B12, vitamin C of equivalent.
The beneficial effects of the present invention are: providing a kind of feed for river crab and its preparation method, the feed nutrition is abundant, mouthfeel
It is good, after river crab is edible, culturing adult river crab is able to satisfy in the nutritional need in growth period, figure improves, and meat significantly improves, and disease-resistant energy
Power is strong, highly-safe.
