Fertility question

[petran79]

At what age do male and female chinchillas stop being fertile or it becomes risky for the female and the offspring?

Does it depend on their life span, eg 20 year olds are more years active?

Does active fertility age span differ between males and females?

They don't ever stop being fertile, they don't go through menopause like humans. Most breeders pull their females from breed by about 10 years old though, but often earlier then that. Once the female is having issues, like having trouble producing milk, not recovering well after birth or having trouble giving birth, they should be removed from breeding regardless of age. Even if still producing well, 10 years seems to be the cut off though, at that point it's like a woman in her 50s still having kids, still possible for some, but a lot more risk.

As far as I know so long as the male is still producing well with the females and isn't having any age related issues that can hurt him during mating there is no age limit.

Interesting.

Thanks for the info
