Method for designing formula of turtle feed in fish-turtle polyculture mode and preparation method thereof

Abstract

The invention provides a turtle feed in fish-turtle polyculture mode and a preparation method of the feed. The feed comprises white fish meal, red fish meal, alpha-starch, extruded soybean, vinegar residue powder, beer yeast, mineral additives, multi-vitamins, feed binder, calcium hydrogen phosphate, sodium dihydrogen phosphate, carnitine, betaine, bile acid, methionine, lysine, nucleotide, choline chloride, and salt. The preparation method comprises the following steps: fully mixing the ingredients with stirring to prepare a feed, then feeding, precleaning, mixing, deironing, crushing, conducting superfine grinding, and mixing. The feed disclosed herein has scientific and reasonable combination, enhances the immunity and contagious virus resistance of the turtle, guarantees the normal growth of the turtle, simultaneously reduces the discharge of nitrogen, phosphor and other pollutants, reduces the pollution to the culture water body, reduces drug dosage, achieves the requirements of ecological breeding, and obviously reduces the cost. The preparation method is scientific and reasonable. The invention has significant economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of feed, and more specifically relates to an environmentally friendly, high-efficiency, and low-cost feed formula for polyculture of fish and turtles and a preparation method thereof. Background technique [0002] Soft-shelled turtle (Trionyx Sinensis) is commonly known as soft-shelled turtle, yuan fish, turtle, 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 the world (there are only 2 genera and 3 species of turtles in China), all of which are produced in subtropical and temperate regions. Because there is a habit of consuming soft-shelled turtles in China, the medicinal and edible value of soft-shelled turtles is highly praised in the theory of traditional Chinese medicine, and has been favored by people since ancient times. However, due to the sharp dec...

Problems solved by technology

However, while industrial farming has high output, it has brought about frequent disease, high mortality, heavy water pollution, and excessive drug residues in soft-shelled turtles. Therefore, it is necessary to seek a safe and reliable breeding model and establish a reasonable breeding feed formula. imminent
