Technical measures to improve the hatching rate of turtle eggs

As we all know, turtles have strong vitality, few epidemic diseases, and are easy to raise and manage, but this is for adult turtles. In the whole process of @ # @ 238 eggs @, carelessness in some links and details will not work. The hatching of turtle eggs is a more technical link, and if it is not done well, it will fail.

1. Scientific cultivation of parent turtles and selection of improved varieties is the first condition to improve the hatching rate of turtle eggs. Parent turtles should be enlarged, strong, without disability and suitable for age. Female turtles are required to be over 6 years old, with wrinkled and slightly hard leathery skin at the posterior edge, while males are required to be 3-4 years old, with a stocking density of 7 animals per square meter, with a male-to-female ratio of 3 ∶ 1.

Second, pay attention to the time of egg collection, the embryo of the egg is fixed only after 830 hours of spawning, so the time of egg collection should be after 3 pm. When there is a heavy rainstorm in the high temperature season, it should be collected in advance.

Third, carefully check that there is a white spot on the top of the well-fertilized egg shell, and its edge is clear and smooth, and the egg is bright pink or white. There is no white spot on the top of the shell, and the color is basically the same, which is an unfertilized egg. The white spot on the top of the shell shows a large irregular leukoplakia, which is a stunted egg. Neither of these eggs can be hatched in the box.

Fourth, there are many materials to use pine as incubator, but pine is better, poplar and willow should not be used. The sand bed of the incubator should maintain a certain humidity. Poplar and willow trees are very easy to grow white mold hyphae after damp. This kind of hyphae permeates among the sand grains, so that the sand grains are impermeable, and the eggs will suffocate and die.

Fifth, using river sand to hatch river sand has good aeration performance and good water retention performance, so the hatching rate is high.

6. the most important thing in controlling the hatching conditions is the temperature and humidity of the sand contacted by the turtle eggs. The temperature should be controlled at 2832 ℃, the highest should not exceed 34 ℃, the lowest should not be less than 25 ℃, and the water content should be 515%, that is, it is appropriate to hold the sand into a ball with one hand and loosen it naturally. Always check the temperature and humidity, if there is any discomfort, you should adjust it in time.
