Ornamental rock turtles, also known as Chinese stone turtles. One of the most popular ornamental turtles today. Many farmers can also breed themselves and breed them. So what’s the problem when breeding ornamental rock turtles?
1. Additional evaporation water of ornamental stone turtle eggs
In a dry environment, the water in the egg will evaporate outward. So does it absorb water in a humid environment to complement previous evaporation? If you’ve ever cultivated stone turtles for breeding, you will know that eggs will constantly absorb moisture in the air. However, relying solely on the amount of water inside the egg is not enough.
Therefore, water control is particularly important. If there is too much water, at the end of the incubation period there will appear spider webs. The ornamental stone turtle shell will be immense. Turtle eggs can be deformed. The word oval turns into a circle. If the amount of water is too small, the eggs hatched in the final stage will dry up. Either the inside of the egg will dry out, but the outer shell is not deformed.
2. Role of yolk and egg white
What is the role of egg yolk and egg white? Some rock turtle breeders peel turtle eggs when the turtles are fully developed but egg yolk is still very large. The question is whether end-time nutrition is provided by egg yolk?
Egg yolk and egg whites are all nutrients for turtles. At the early stages of the incubation process, the embryo nutrition is primarily from egg whites. In later stages, baby turtles will absorb the mixture of egg yolk and egg white.
Now there will be a protein membrane covering the whole white. The whites and egg yolk are blended together. This is the yolk sac you see. And after this part is fully absorbed, the baby turtle will eat.
In fact, when the egg is fertilized, the egg yolk will probably sink. You can use LED to observe eggs. And egg whites to keep moisture for ornamental stone turtle eggs.
3. What are white spots on ornamental stone turtle eggs?
When incubating eggs, start from the point where the white spot appears, the direction should be set. Because that position is the position of the embryo. So what is white spot? Why, along with the self-development of the embryo, will the white spot gradually grow?
The appearance of white spots shows the development of embryos. The fact that embryos begin to absorb calcium in eggshells. The more calcium a fetus absorbs, the more white spots will spread. In the later stage of the incubation process, ornamental stone turtle eggs will appear black shadows. This happens when the turtle has grown inside the egg. Maybe the skin is black or the back is close to the shell. This is usually the marker for the upcoming turtle coming out of the shell.
4. Effect of egg migration
The reversal of the egg 180 ° during the incubation process will cause the embryo to stop growing. Because after the eggs are removed from the body, the plant and animal poles will be formed in 24 hours. If turning 180 ° will reverse the formation of the two poles. Therefore the development cannot be done normally. However, at the end of the incubation period, if the overturning is not done properly, it will have no big effect.
In fact, during the incubation process, just not the newly laid eggs, the effect of moving on the eggs is not large. Mistakes are often caused by excessive heat, not movement.
