As we all know, turtles have strong vitality, few epidemics, and are easy to raise and manage, but this is true for adult turtles. In the entire process of raising a turtle, certain links and details are careless. The hatching of turtle eggs is a technically strong link, and if it fails, it will fail. The 6-point method for increasing the hatching rate of turtle eggs is described below.
First, science nurtures turtles
Selecting good breeds is the primary condition for improving hatchability of turtle eggs. Turtle should be individual hypertrophy, robust, no disability, age appropriate. Female turtles require more than 6 years of age, and the trailing edge of the leathery skin has wrinkles and is slightly stiff; males require 3rd to 4th instars, and stocking density is 7 per square meter, with a ratio of 3:1 male to female.
Second, pay attention to the time of picking eggs
After the turtle lays eggs for 8 hours to 30 hours, the eggs' embryos are fixed, so the time for picking eggs should be after 3 pm. When there is heavy rain in hot seasons, it should be collected in advance.
Third, carefully check the fertilized eggs
Well-developed fertilized egg shells have white spots on the top, and their edges are clear and sleek, and their egg color is bright pink or white. The white spots on the top of the shell are not visible, and the color is basically the same, which is an unfertilized egg. The white spots on the top of the shell are large irregular white spots and are stunted eggs. Both eggs cannot be hatched.
Fourth, using pine to do incubator
There are many materials for incubators, but pine is better than poplar and willow. Incubator box sand bed to maintain a certain humidity, poplar, willow wood easily grow white mold hyphae, the hyphae infiltrated between the sand, so that sand compacted impermeable, eggs will suffocate premature death.
V. Using river sand hatching
River sand ventilation performance, water retention performance, and therefore high hatching rate.
Six, control hatching conditions
The most important of the hatching conditions is the temperature and humidity of the sand the turtle eggs are in contact with. The temperature should be controlled at 28 °C ~ 32 °C, the maximum can not exceed 34 °C, the minimum must not be less than 25 °C, the water content of 5% to 15% is appropriate, that is, a hand hold sand into the group, loosen the natural spread is appropriate . Always check the temperature and humidity, if any, adjust in time.
