The rate of growth and development of the Brazilian turtle and the basic conditions for its survival

First, look at the latitude, if the winter has been below freezing, absolutely not.

Second, look at the medium during hibernation, soil, hay, etc., which can play a role in heat preservation.

Third, depending on the physique of the turtle, if the turtle is sick or poorly nourished, it must not hibernate.

In summary, natural hibernation below 5 degrees is not recommended.

<> Brazilian turtle grows faster in the early stage, growing 40-100 grams a year. Generally, a one-year-old turtle has about 15 grams, a two-year-old turtle has almost 50 grams, a three-year-old turtle has almost 100 grams, and by the age of four, they can weigh about 200 grams. To grow them, you need to prepare a glass container with water and sand in it.

Fish, shrimp and snails can be fed at ordinary times, and synthetic turtle food can also be fed.

<> red-legged tortoise When it comes to calculating the age of the tortoise, many people's first reaction is to count the lines on the tortoise shell like counting the rings, is this really accurate? The shell of some wild turtles can really see the lines clearly after the baptism of time?

1. Concentric rings on the shield

With the periodic change of nature, the turtle has an obvious growth period and hibernation period, the dorsal carapace shield grows like the body during the growth period, forming a loose and wide concentric ring circle, the tortoise enters a dormant state during the hibernation period and stops growing, and the dorsal carapace shield almost stops growing, forming a narrow and tight concentric ring circle. Such dense concentric rings are similar to the age of a tree based on its growth rings, and a growth ring occurs when it experiences a winter when development stops. Based on this, the age of the turtle can be determined, that is, the number of concentric rings on the shield, and then add 1 (the broken shell is born as a ring), which is equal to the actual age of the turtle.

This method can only be calculated when the concentric ring pattern of the turtle's back carapace is clear, the annual ring of the turtle is clearer before the age of 10, and soon after the birth of the juvenile turtle, the shield outside the shell ** on the outer hard ** see some radial lines, and there is no round wheel, there are several rings of the turtle's back carapace, that is, how old the turtle is, the longer the age is more difficult to identify with the naked eye, only according to the weight of the turtle to calculate, except for artificial breeding, the wild turtle per 500g weight of the turtle age, about 20 years in the south of our country, about 40 years in the north of the turtle.

2. Weight

The growth rate of the turtle is relatively slow, under normal conditions, the growth rate of the female turtle is about 15 grams, the weight of the first-year-old turtle is about 15 grams, the second-year turtle is 50 grams, the third-year turtle is 100 grams, the fourth-year-old turtle is 200 grams, the fifth-year-old turtle is 250 300 grams, and the six-year-old turtle is about 400 grams. Male turtles grow slowly, and the maximum sexual maturity is generally less than 250 grams.

3. Turtle shell pattern

The approximate age can be derived from the texture of the turtle shell**, the darker the color orange cherry, the clearer the texture and the older, and vice versa, it is tender, if it is the actual age, it is difficult to judge. Methods for identifying the age of a tortoise. It is to look at the lines on the carapace on the back of the turtle, that is, the number of circles, there are circles on each carapace, and the number of circles represents the age.

The more laps you have, the older you get. The age of the turtle is generally calculated by the number of concentric rings on the shield on the back of the turtle, and each circle represents a growth cycle, that is, one year. The number of concentric rings on the shield, and then add 1 (one year after the broken shell is born) is the age of the turtle.

This method can only be calculated accurately when the concentric rings of the tortoise carapace are clear, and the approximate age of the old turtle or the concentric rings are blurred, can only be estimated.

Normal feeding can be seen through the above 3 methods, but some turtles, early feeding is turtle food, everyone knows that turtle food has hormone components, so the turtle will grow faster, so it is difficult to calculate his age, can only be roughly judged, so that the above methods can really only be referenced. There are also some turtles that are caught from the river or other places, and this one is released or wildened, so the approximate age can only be obtained by the above method, which is not accurate.

In the case of tortoises, they distinguish between water turtles and semi-water, so the calculation method is also different, so it is not suitable to use the above method to calculate.

The Brazilian turtle has no effect on its growth period at a temperature of around 25°.

The Brazilian turtle is an aquatic turtle, which likes to be quiet and afraid of noise, likes warmth and is afraid of cold, is active by nature, and has a strong ability to adapt to the environment, such as its tolerance to temperature changes is stronger than that of domestic turtles such as turtles and yellow-throated turtles. The water temperature suitable for search and growth is 20 degrees Celsius to 30 degrees Celsius, and the optimal water temperature for growth is between 25 degrees Celsius and 30 degrees Celsius.

It can be seen that because the optimal water temperature for the growth of Brazilian turtles is between 25 and 30 degrees Celsius, there is no effect on the growth of Brazilian turtles when the temperature is 25 degrees Celsius.

At the beginning of July of the first year, the first seedlings are 8 grams, and the feeding amount can grow to 50 grams at the end of November, which is six times longer.

In December and February, hibernation does not last long.

After hibernation in March of the following year, 5% (g day) is fed until December of the following year. It can grow up to 500 grams (another 10 times longer).

December and February, hibernation.

Feeding began in March of the third year, with a feeding amount of 25 grams per day. The conversion rate is 15 grams per day. By December it can reach 5kg

How to know the growth of a Brazilian tortoise: The simplest three can tell if the tortoise is growing.

If you look at the amount of food the turtle eats, the more the turtle eats, the faster it grows. On the contrary, the slower, or not longer.

Second, look at the block seam on the back of the turtle, whether there is a strip of white line, the wider the white line, the faster it grows.

Third, you can weigh the weight with a scale regularly and make a record.

How long do you think it takes to see it grow up?

Depending on the method of feeding, food, etc., the rate of growth will be different. Generally speaking, the more you eat, the faster it grows, and it is obvious that the turtle is growing after 15-30 days.

Biological characteristics of the Brazilian tortoise

1. Morphological characteristics of the Brazilian tortoise

The Brazilian turtle is mainly divided into six species, including the Brazilian golden turtle, the Brazilian chicken turtle, the Brazilian painted turtle, the red-eared turtle, the red-bellied turtle, and the Mississippi turtle, but they are collectively referred to as the Brazilian turtle. In general, the Brazilian painted turtle has a wide head, a longitudinal stripe with yellow and green on the neck, and a red stripe on the back of the eye. The dorsal carapace of the Brazilian painted turtle is flattened, generally emerald green or apple-colored, with a distinct ridge on the back**, and then the shield is covered with yellow and green ring-like stripes.

The limbs are pale green, with grayish-brown longitudinal stripes, webbed between the toes; The most striking feature of red-eared turtles is the presence of red spots behind the eyes, which is also the key point to distinguish red-eared turtles.

Although there are different breeds of Brazilian tortoises, they are all collectively known as Brazilian tortoises and have two distinct characteristics:

1. The Brazilian turtle is colorful, with red and light green stripes on the head, and a blue and dark green belt on the back, showing a regular geometric pattern, and the yellow, white and black oracle bone text patterns are distributed at the web, and the patterns of different Brazilian turtles are varied, so the Brazilian turtle is known as the mahjong turtle;

2. Brazilian turtles are more active, more active and faster than many other turtle species, and generally do not want turtles.

It is slow to move, so the Brazilian tortoise is relatively valuable for its ornamental value.

2. The living habits of the Brazilian tortoise

1. Brazilian turtles like to eat animal feed, such as small fish, small shrimp, mussels, snails, bloodworms, earthworms, lean meat, etc. But when animal-based feed is scarce, they also eat plant-based feed. Usually, if you feed animal feed to Brazilian turtles, you must pay attention to carefully check the feed before feeding, and avoid feeding rotten and spoiled food.

The Brazilian turtle has a wide range of diets and is more mixed, and it is also hungry tolerant, and can endure prolonged hunger.

2. The Brazilian turtle has a strong ability to adapt to the environment, but this does not mean that the Brazilian turtle loves any environment. In captivity, it is found that the Brazilian tortoise prefers a quiet, clean environment. Brazilian tortoises are timid, afraid of sounds, and prefer to roost in quieter places.

3. Among Brazilian turtles of the same age, the tail of the female turtle is generally smaller than that of the male turtle, and the belly is flat or convex. Male turtles have a long, thick tail and a concave belly, but it is difficult to identify newborn chicks.

4. Brazilian tortoises are oviparous animals, generally mating in May and August, and laying eggs in June and September. Around the summer solstice is the peak spawning period for Brazilian turtles, they can lay eggs about 3 or 4 times a year, and the number of eggs is around 40, and the maximum number can reach 90. Brazilian tortoises can hatch on their own at natural temperatures, but artificial hatching is much higher in comparison.

The above is an introduction to the morphological characteristics and living habits of the Brazilian turtle, I hope it can help you understand the Brazilian turtle in-depth. If you want to know more about pet turtles, you can pay attention to the later sharing.
