5 kg Brazilian tortoise about 3-5 years, the specific number of years depends on the way of breeding. Generally speaking, the development speed of Brazilian tortoises living in the wild is relatively slow, and it takes them more than 5 years to grow to 5 kg. The Brazilian tortoise in captivity will develop faster, but it also depends on the way it is raised. If they are raised at home, giving them enough food and space, but allowing them to hibernate naturally, they can grow to about 5 kg in only 5 years. If Brazilian tortoises are specially raised, keep the temperature constant indoors all the time, and have sufficient food and nutrition, they can grow to 5 kg in only about 3 years.

To determine the specific age of Brazilian tortoises, breeders can look at the shields on their carapace. There will be rings on their shields, one ring represents one year old, and the number of rings on the shields plus one is their actual age.

The life span of Brazilian tortoises is between 15 and 35 years, and the life span varies with different living environments. Wild tortoises live longer, about 25-35 years. Of course, there are also special ones that can live for more than 35 years, but they are not common. The life span of Brazilian tortoises raised at home is generally between 15 and 25 years, and the specific life span is judged according to their physique and feeding methods.
