Hatching method of Annan turtle eggs

Abstract

The invention discloses an Annan turtle egg hatching method which specifically comprises the following steps: stage 1, cleaning the surfaces of picked Annan turtle eggs, and placing the cleaned Annan turtle eggs in an environment of 27-31 DEG C for 5-8 days; stage 2, placing the Annan turtle eggs after the stage 1 is completed in an environment of 25-28 DEG C for 7-28 days, and when strip-shaped blocks are developed on the turtle eggs, placing the turtle eggs in an environment of 28-30 DEG C until the Annan turtles are hatched; or when strip-shaped blocks are developed on the eggs of the Annan turtles in the first stage, the eggs of the Annan turtles are placed in the environment of 28-30 DEG C until the Annan turtles are hatched. According to the method provided by the invention, the hatching of the Annan tortoise is divided into two stages, and by controlling the hatching conditions such as temperature and humidity of the Annan tortoise eggs in the second stage, the sex ratio of the hatched male and female tortoise eggs can be further controlled, the hatching survival rate is higher, and the influence of diseases on hatching is further reduced.

Description

technical field [0001] The application relates to the technical field of feeding or breeding, in particular to a method for hatching Annan turtle eggs. Background technique [0002] Annan turtles are distributed in the central part of Vietnam, and their appearance is very similar to that of the yellow-throated terrapin. The breeding season is from May to October every year, and the spawning season in Guangdong is from May to July. They lay eggs 1-3 times a year, and each time they lay eggs (Number of eggs) 4-9 pieces, the eggs are oblong, off-white, weighing 10-20 grams, with a long diameter of 314-553 cm and a short diameter of 175-267 cm. [0003] The hatching of turtles has a great relationship with temperature and humidity. Famous turtles such as stone money turtles, money turtles, and Annan turtles have more males than females. Many farmers study how to hatch male turtles in order to balance the ratio of males to females. Temperature control is the key to the incubatio...

AI Technical Summary

Problems solved by technology

In a constant temperature environment, when the temperature is maintained at about 29°C, the ratio of male to female can reach 1:1. If the temperature is higher than this temperature, there will be more females, and if the temperature is lower than this temperature, there will be more males. Some farmers use pure vermiculite or pure yellow mud
