Quick-frozen fresh feed for aquatic products and preparation method of quick-frozen fresh feed

Abstract

The invention discloses a quick-frozen fresh feed for aquatic products and a preparation method of the quick-frozen fresh feed. The quick-frozen fresh feed consists of the following formula components in parts by mass: 5-15 parts of cooked lobster pulp, 4-6 parts of flavomycin, 2-4 parts of rovimix, 8-12 parts of cooked silver carp pulp, 12-14 parts of cooked pork livers and lungs, 3-5 parts of vitamins, 2-4 parts of a compound enzyme, 7-9 parts of rhubarb-baical skullcap root-Chinese corktree bark powder, 16-18 parts of pig blood, 15-25 parts of cooked soybean meal, 3-5 parts of choline chloride, 13-15 parts of patent flour, 5-7 parts of calcium dihydrogen phosphate, and 1-3 parts of quinocetone. The invention provides a quick-frozen fresh feed for special aquatic products, which is high in production speed and yellow in color, has no scars and boils, is nutritional and delicious in meat quality, and can reduce disease incidence, and a production process thereof.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a quick-frozen fresh feed for aquatic products and a preparation method thereof. Background technique [0002] In the aquatic industry, aquatic products such as turtles, soft-shelled turtles, eels, shrimps, and crabs are usually called special aquatic products. Due to their high nutritional value, people began to breed them in large quantities. The current formula of soft-shelled turtle feed in the market is: white fish meal 33% Peruvian fish meal 28% brewer's yeast powder 5% whole milk powder 4% puffed soybean 8.1% cooked starch 17% calcium dihydrogen phosphate 1.4% premix 3.5%. There are two forms of production: one is pure dry powder, which must be mixed with appropriate water (fish paste) and 2-3% fish oil to form a dough when feeding, which is laborious and time-consuming. For a long time, there is a fever (oxidation reaction) in the feed. The temperatu...

Problems solved by technology

There are two forms of production: one is pure dry powder, which must be mixed with appropriate water (fish paste) and 2-3% fish oil to form a dough when feeding, which is laborious and time-consuming. For a long time, a fever occurs in the bait (oxidation reaction)

The temperature difference between the inside and outside of the material is 2-3°C. Turtles eat high-calorie food and frequently eat unclean water in fish ponds, which can easily lead to digestive system infections, reduce the immunity of the turtle itself, and lead to a large number of individual deaths in severe cases.

Another kind of extruded granulation or granule floating feed. During the processing of this material, the raw material can only be formed after being matured by the modulator. The temperature of the modulator is mostly controlled above 92°C. The high temperature and high pressure steam seriously damages the protein and protein of the raw material itself. Vitamins, resulting in incomplete feed nutrition, affecting the digestion and absorption of soft-shelled turtles. If the puffed material floating in the water is not eaten in a short time, it will be quickly lost in the pond, polluting the water quality and causing illness

Therefore, at present, special aquatic products cannot be directly fed. The residual bait and bad water will quickly cause many diseases, and the feed price is high, making the aquaculture industry a high-risk and high-input industry, which seriously dampens the enthusiasm of farmers.
