Good-palatability feed for juvenile soft-shelled turtles

Abstract

The present invention relates to a good-palatability feed for juvenile soft-shelled turtles. The good-palatability feed is prepared from the following components in parts by weight: 25-35 parts of fish meal, 4-6 parts of eel bones, 4-6 parts of donkey blood, 1.5-2.5 parts of roots of glutinous rice, 0.1-0.3 part of sandalwood oil, 4-6 parts of purple sweet potato flour, 4-6 parts of zein, 0.1-0.3 part of sweet peptide, 1.5-2.5 parts of rice protein, 15-25 parts of vegetable feed, 4-6 parts of earthworm flour and 0.1-0.3 part of fennel powder; during preparation, the components are mixed uniformly and are fed to a granulator for granulation. According to the good-palatability feed for the juvenile soft-shelled turtles, all raw materials do not contain substances harmful to health and growth, the source of the raw materials is wide, the preparation process is simple, the cost is low, and the juvenile soft-shelled turtles can be rapidly attracted to feed and additionally feed, so that the survival rate and growth speed of the juvenile soft-shelled turtles are increased, and the autoimmunity of the juvenile soft-shelled turtles is enhanced.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a young soft-shelled turtle feed with good palatability and high nutrient content. Background technique [0002] Soft-shelled turtle, commonly known as soft-shelled turtle, yuan fish, group fish, water fish, bastard and so on. In animal taxonomy, it belongs to the phylum Vertebrate, Class Reptilia, Order Turtle, Turtle Branch, and Genus Turtle. There are more than 20 species and subspecies in this genus (there are only 2 genera and 3 species of soft-shelled turtles in China, 1 species of soft-shelled turtle, 2 species of soft-shelled turtle, juvenile soft-shelled turtle and Shanrui soft-shelled turtle), all of which are produced in temperate and subtropical Asia. Juvenile soft-shelled turtles have been favored by people since ancient times because of their high nutritional and medicinal value and delicious taste, and are popular in domestic and foreign markets. Due to the sharp re...

Problems solved by technology

However, high-input, high-yield, high-tech factory breeding of soft-shelled turtles has certain risks. If the daily management is not in place and the selection of compound feed is improper, it is likely to cause frequent soft-shelled turtle diseases and high mortality.

In addition, after many soft-shelled turtles are fed with feed, the soft-shelled turtles do not like to eat, there are many residues, the conversion rate is low after feeding, and a large amount of nitrogen and phosphorus are emitted, which causes serious pollution of the breeding water, causing the prevalence of soft-shelled turtle diseases and serious death

Some farmers use a large amount of drugs for unscientific disease prevention and control. As a result, the drug residues in commercial soft-shelled turtles seriously exceed the standard, endangering the health of consumers. In recent years, there have been frequent incidents of toxic aquatic products in my country, all of which are caused by the indiscriminate use of drugs.
