Juvenile Chinese softshell turtle expanded feed and preparation method thereof

Abstract

The invention relates to a juvenile Chinese softshell turtle expanded feed. The juvenile Chinese softshell turtle expanded feed comprises the following components in parts by mass: 20 to 25 parts of small trash fishes, 10 to 15 parts of water earthworm meal, 5 to 10 parts of yam flour, 8 to 10 parts of purple sweet potato flour, 4 to 6 parts of orange peel powder, 5 to 8 parts of egg yolk, 4 to 7 parts of egg white, 0.06 to 0.1 part of glycine, 0.5 to 0.8 part of krill oil, 0.1 to 0.15 part of tea polyphenol, 0.05 to 0.1 part of glycine betaine, 0.02 to 0.04 part of monocalcium phosphate, 0.1 to 0.25 part of soybean oligosaccharides, 0.1 to 0.18 part of xylooligosaccharide, and 0.08 to 0.1 part of plant adhesive. The invention also relates to a preparation method of the juvenile Chinese softshell turtle expanded feed. Compared with the prior art, the juvenile Chinese softshell turtle expanded feed has the advantages that the nutrition is rich, the nutrition required by the growth of juvenile Chinese softshell turtle is provided, the survival rate and growth rate of juvenile Chinese softshell turtle are obviously improved, the feed coefficient is reduced, the stability in a water body is good, the easiness in disintegration is avoided, the waste of feed is little, and the pollution to water quality is little.

Description

technical field [0001] The invention relates to the field of aquatic product feed, in particular to a Chinese soft-shelled soft-shelled turtle puffed feed and a preparation method thereof. Background technique [0002] Soft-shelled turtle, also known as soft-shelled turtle, is a common farmed turtle species. Soft-shelled turtle has a unique flavor and rich nutrition. It is a high-protein and low-fat food material. Its tissues are rich in polysaccharides, collagen, taurine, and vitamin B- 17 and other functional factors have certain effects in the prevention and treatment of cardiovascular and cerebrovascular diseases, anti-tumor, enhancing immunity and delaying aging. [0003] The growth and development of soft-shelled turtles can generally be divided into three stages: immature soft-shelled turtles, juvenile soft-shelled turtles and adult soft-shelled soft-shelled turtles. At present, special feeds suitable for juvenile soft-shelled turtles and adult soft-shelled turtles h...

AI Technical Summary

Problems solved by technology

However, there is no special feed for juvenile soft-shelled turtles, and juvenile soft-shelled turtles have higher requirements for feed, requiring feed that is refined, fine, soft, fresh, tender, comprehensive in nutrition, and good in palatability.

In the traditional feeding method, red worms, mysis shrimp, silk earthworms, chironomus larvae, etc. are usually fed within one month after juvenile soft-shelled turtles emerge from their shells. Chicken, duck egg yolk, animal liver, etc. can also be fed. Maggots, earthworms, small shrimps, minced surimi, animal offal, large fish and shrimps, river mussels, snails, etc. are troublesome to raise
