Compound feed of mature trionyx sinensis and preparation method thereof

Abstract

The invention provides a compound feed of a mature trionyx sinensis and a preparation method thereof. The compound feed comprises fish meal, alpha-starch, fermented soya bean meal, fish oil, yeast, methionine, lysine, milk powder, yolk powder, compound mineral premix for trionyx sinensis feeds, compound vitamin premix for the trionyx sinensis feeds, monocalcium phosphate, enzymic preparations and Chinese medicinal herb additives. The preparation process comprises the following steps of: charging materials; initially cleaning; mixing for the first time; removing iron; smashing; mixing for the second time; and packaging. The invention has scientific and reasonable collocation of a feed formula, enhances the disease resistance of the mature trionyx sinensis, selects feed raw materials with high digestive absorption rate, enhances the conversion rate of the feed, decreases the diseases of the mature trionyx sinensis by reducing the discharge of pollutants, i.e. nitrogen, phosphorus, and the like, and the pollution of culturing water bodies, finally meets the requirements for ecological culture by reducing medicine dosage, enhances the absorption utilization rate of the feed, and can meet the nutritional requirements of the mature trionyx sinensis, reduce the culture cost and also reduce the pollution of the water bodies; in addition, the preparation method is scientific and reasonable and has outstanding economic benefit and environmental benefit.

Description

technical field [0001] The invention belongs to the technical field of feed, and more specifically relates to a compound feed for soft-shelled soft-shelled turtles and a preparation method thereof. Background technique [0002] Chinese soft-shelled turtle ( Trionyx Sinensis ) are 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, Chinese soft-shelled turtle and Shanrui soft-shelled turtle), all of which are produced in temperate and subtropical Asia. Soft-shelled turtle has been favored by people since ancient times because of its high nutritional and medicinal value and delicious taste, and is popular in domestic an...

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.
