How old can the "ecological killer" Brazilian tortoise grow in a year? How many jin can you gain at most? How old can you lay eggs?

Although the Brazilian tortoise is recognized as an "ecological killer" in the world and has been listed as a dangerous alien invasive species in many countries, because of its lovely shape, gorgeous color, great ornamental value, and easy to raise, so there are still many people like to keep Brazilian turtles as pet turtles. So, how old can Brazilian turtles grow in a year? How many jin can you gain at most? How old can you lay eggs?

Because of the large food intake of Brazilian turtles, Brazilian turtles grow very fast, and how big can Brazilian turtles grow in a year? it can be said that young turtles hatched from July to September, under normal temperature, adequate food and normal culture conditions, can reach an average of 25-40 grams before overwintering in that year, and more than 200 grams in the next year, and more than 400 grams in the third year.

Intuitively speaking, if you buy a Brazilian tortoise bigger than a coin, the second year is the size of the lid of a purple sand teapot, the third year is the size of a mouse, the fourth year is as big as the mouth of a rice bowl, and the fifth year is as long as an unrolled napkin.

As for the weight of Brazilian turtles, there is no significant difference between females and males in appearance and color, but there is a great difference in weight. Sex can be identified when the female weighs 1000 grams and the male weighs 250g. The weight of the female individual can reach 1000 to 2000 grams, the ventral nail is flat, and the cloacal hole is within the back edge of the dorsal nail, while the male individual weighs no more than 500 grams, the claws of the limbs are longer and the tail is longer. Of course, there are also some differences in size and weight among different individual Brazilian turtles.

In terms of body length, the total length of Brazilian turtles is about 15-25cm, which can grow up to 55.5cm, which was found in the United Kingdom. Due to limited conditions, Brazilian turtles can survive for more than 20 years, and it is not a problem to grow 20 to 30 centimeters. It usually grows about 2-8 centimeters a year.

Of course, how old the Brazilian tortoise can grow depends on the owner's usual feeding, mainly in terms of diet, such as meat, shrimp, fish, etc., anyway, it is necessary to eat very well, pay attention to utensils, temperature, water hygiene, and so on, Brazilian turtles will not get sick. Even if the Brazilian tortoise is sick, it is still willing to eat and it still grows! As long as you notice that the Brazilian tortoise's shell grows a new shell, its limbs and head also begin to molt, which means it is growing!

In order to understand Brazilian turtles in more detail, Professor J.W.Gibbons (1987), an American reptile ecologist, observed the lifespan of Brazilian turtles by sign weight method. After 23 years of research, it was found that only 3.4% of the more than 10, 000 turtles lived for more than 25 years, 7.3% lived for 20-24 years, 21.4% lived for 15-21 years, and 68% lived less than 15 years. Of course, under certain breeding conditions, Brazilian turtles may live longer.

So, how old is the Brazilian turtle to lay eggs? Generally speaking, for turtles of the same age, females are always larger than males. The common Brazilian tortoise male tortoise weighs 300 grams, and the female tortoise weighs 500 grams. Other turtles have different standards according to different species. Generally speaking, Brazilian turtles grow to more than a kilo of sexual maturity before they can lay eggs and hatch their young.

Tips is raised by Brazilian turtles

Young Brazilian turtles can be raised in a flat-bottomed container without difficulty. Plastic pots, plastic tanks or boxes, and aquariums are all suitable, and the water is not too deep. A flat plastic trough sold in the market with an island and a plastic coconut tree in the middle is the least suitable because: (1) it is too small; (2) cannot install an electric heater; and (3) mislead users into using the island as a place to feed. Because the Brazilian turtles eat completely in the water, the result may be that the island is piled with fodder, while the Brazilian turtles are starving.

An ideal nursery must have some specific minimum requirements. Each baby turtle should have five liters of water, and the water depth should not exceed the length of the tortoise, so that the turtle's feet can reach the ground when it comes to the surface to breathe. At the same time, they must also use bricks and stones to make an island. Floating islands are not applicable because young turtles are often unable to climb up. On the other hand, pay attention to the island and decorations do not become dangerous obstacles, the turtle stuck and drowned. An ideal nursery must have some specific minimum requirements.

If it is suitable for its growth temperature, it will grow faster. The suitable water temperature for Brazilian turtle growth is 20-32 ℃, and the best growth water temperature is 25-30 ℃. When the food intake was below 20 ℃, the food intake was reduced and the activity was not active; when the food intake was below 15 ℃, the food intake was basically stopped; and the activity below 10 ℃ was significantly decreased and was in a semi-dormant state.

In addition, Brazilian turtles are omnivorous animals, which are mainly carnivorous when raised, especially in the juvenile and juvenile stage, with small fish and shrimp and lean animals as the main food. In the adult stage, the turtle can also eat plant feed and artificial feed.
