Culture method for tea-flavored soft-shelled turtles

Abstract

The invention relates to a culture method for soft-shelled turtles, in particular to a culture method for tea-flavored soft-shelled turtles. The invention mainly solves the technical problem of how to digest, absorb and utilize the nutrient trace elements of green tea for conversion in soft-shelled turtles after green tea powder is added into the feed of soft-shelled turtles. The steps of the culture method are as follows: preparation of puffed feed: feed materials containing the green tea powder are poured into puffing equipment, and after continuous mixing, heating, pressurization, cooking, extrusion out of a mold hole and depressurization, the puffed feed is produced; the formula of the puffed feed and the percentages by mass of the ingredients are as follows: 25 to 35 percent of fish meal, 19 to 25 percent of fermented active soybean meal, 4.5 to 6.5 percent of puffed pig blood powder, 5 to 10 percent of fly maggot powder, 14 to 16 percent of Alpha starch, 7 to 9 percent of puffed corn starch, 5 to 7 percent of yeast, 1 to 2 percent of multiple vitamins, 0.5 to 1.5 percent of multiple mineral substances, 0.1 to 1 percent of monocalcium phosphate, 0.1 to 1 percent of choline chloride and 2 to 4 percent of green tea powder; soft-shelled turtles are then fed two times or more than two times each day according to 0.5 to 2 percent of the weight of the soft-shelled turtle; the color of water needs to be kept normal, and after being cultured for 150 days, grown soft-shelled turtles, each of which is equal to or more than 600g, can be yielded.

Description

technical field [0001] The invention relates to a method for cultivating soft-shelled turtles, in particular to a method for cultivating tea-flavored soft-shelled turtles. Background technique [0002] The soft-shelled turtle is a reptile that lives in water, and has similar living habits and environmental requirements to fish; the soft-shelled turtle is an omnivorous animal with a partial carnivorous nature, which has the functions of nourishing, strengthening and prolonging life, and has high nutritional value. , deeply loved by consumers. What conventional culture soft-shelled turtle generally adopts is " two-step culture method ". That is, juvenile soft-shelled turtles are cultured in the greenhouse, and adult soft-shelled turtles are cultured in outer ponds. A Chinese patent discloses a pollution-free large-scale soft-shelled turtle ecological breeding method (patent publication number: CN 1895034A). The steps are as follows: a. Selection of breeding ecological enviro...
