A kind of intensive breeding method for soft-shelled turtle breeding period

Abstract

The invention relates to an intensive cultivation method for use at the breeding season of parent turtles. The method comprises the following steps: preparing a cultivation pond; selecting and pairing the parent turtles; performing feeding management. During feeding, a formula I feed and a formula II feed are adopted for feeding, and each cycle lasts for seven days. On the first and second days, the formula I is fed at the daily feeding amount of 5-10 percent; on the third day, the formula II is fed at the daily feeding amount of 5-10 percent, and 5 international units of vitamin E is added to every kilogram of bait; on the fourth day, the formula I is fed at the daily feeding amount of 5-10 percent; on the fifth, sixth and seventh days, the formula II and a full-value turtle feed are fed at the daily feeding amount of 4-8 percent, and 5-10 international units of vitamin E is added to every kilogram of bait. By adopting the optimized parent turtle production management method, a stable and regular living environment is created, the egg yield, fertility rate, juvenile soft-shelled turtle survival rate and the like of the turtles are increased, and the egg laying quality is enhanced.

Description

technical field [0001] The invention relates to a method for intensifying breeding of soft-shelled turtles. Background technique [0002] In the natural environment, the egg production, fertilization rate, hatching rate, and survival rate of juvenile soft-shelled turtles are very low. After artificial domestication, due to sufficient nutrition, no invasion of predators, and improvement of artificial hatching equipment, the fecundity of soft-shelled turtles has been greatly improved. . At present, most fine-bred soft-shelled turtle farms can achieve an annual egg production of more than 50 female soft-shelled turtles, a fertilization rate and hatching rate of more than 80%, and a survival rate of juvenile soft-shelled turtles of more than 60%. The fecundity and juvenile soft-shelled turtle quality will be further improved, thereby improving production efficiency and increasing enterprise benefits. Among them, the egg production, egg quality, and fertilization rate of the fe...

Problems solved by technology

[0003] At present, in the reproduction process of soft-shelled turtles, female soft-shelled turtles often produce few or no eggs, low fertilization rate, uneven hatching of juvenile soft-shelled turtles, and low survival rate of juvenile soft-shelled turtles. Optimize production management methods, rationally mix bait, etc.
