Trionyx sinensis breeding feed and its preparation method

Abstract

The invention discloses trionyx sinensis breeding feed and its use and preparation method. The trionyx sinensis breeding feed comprises trionyx sinensis compound feed and nano-zinc oxide mixed with the trionyx sinensis compound feed. Nano-zinc oxide is a nanoscale nutrient, can diffuse by passive transport so that the physical agility of an aquatic animal is saved, can be transported to tiny blood capillaries so that a zinc absorption rate is improved. Nano-zinc oxide can diffuse fast and thus a body can synthesize zinc-containing substances in a shortest period so that it is caused that the changes of a zinc-containing enzyme level, the secretion of a hormone related to zinc and zinc finger proteins influence the synthesis and the level of insulin, sex hormones and zinc finger proteins. Therefore, protein synthesis is promoted; nitrogen utilization efficiency of an animal is improved; excretion of nitrogen of manure and urine is reduced; and the pollution produced by nitrogen on the environment is reduced. Nano-zinc oxide has a certain moldy feed defense capability and thus when moldy feed enters into an intestinal tract, nano-zinc oxide can adsorb mycin of the moldy feed and discharge the mycin from the body so that disease prevention is realized and a physical ability of an aquatic animal is improved.

Description

technical field [0001] The invention relates to a soft-shelled turtle breeding feed and a preparation method thereof. Background technique [0002] Chinese soft-shelled turtle has high nutrition, delicious taste and medicinal value. It has been favored by nutritionists and the public since ancient times, and has a great market demand. However, the natural source of soft-shelled turtles is limited, the contradiction between supply and demand is increasingly prominent, and the price is high. Therefore, Chinese soft-shelled turtle aquaculture develops rapidly. [0003] The breeding of soft-shelled turtles can be divided into natural ecological breeding mode and indoor constant temperature factory breeding mode. In the natural ecological breeding mode, it takes 2-4 years to obtain a product size of about 1.2 catties / bird, and the product cycle is too long. [0004] Actual farming can take the form of combining constant temperature factory farming and natural ecological farmin...

AI Technical Summary

Problems solved by technology

[0005] Facts show that no matter what farming model is adopted, there are still some problems that affect the growth of soft-shelled turtles

[0006] 1.1 Improper feed formula leads to frequent soft-shelled turtle diseases and decreased survival rate

[0007] 1.2 After the feed is put in, the taste is not right, and the soft-shelled turtle does not like to eat it, resulting in a lot of feed residue, so the feed conversion rate is low, and the residual food will also emit a large amount of harmful substances such as ammonia nitrogen, nitrite, etc., causing serious pollution to the water body of the breeding pond, causing soft-shelled turtles epidemic, increased mortality

[0008] 1.3 Drug treatment was used, and the drug residues in commercial soft-shelled turtles seriously exceeded the standard, which caused adverse effects on consumers, and even poisonous aquatic products incidents occurred, endangering the health of consumers
