Was watching show about tigers few question

Question

you know how people buy cubs and then they outgrow them. and said its hard find homes because zoos wont take them because they cross breeds. why is that? tigers on the danger list so why not

and since somewhat hard for tigers to breed infirst place why not zoo vets take the semem and self induce it into female so they increase the pouplation they can do this even in wild if they wanted to

Answer 1

Well because there not purebred tigers... then there not really scientifically on the list...and the zoo wont breed them with full tigers because they will get more mix tigers. Also some do that but others think its better to let it happen naturally and female tiger dont go into heat alot... and they have to wait along time before it can mate.

Answer 2

they eat caca.

Answer 3

The idea of captive breeding is to ensure genetic diversity and purity. Whilst it's true that a cross between, say, a Bengal tiger and a Siberian tiger is still a tiger, it could not be reintroduced to the wild because it has mixed genes. It might not survive in India because of the Siberian genes it carries, and vice versa, and if it did survive it would dilute the existing population with its foreign genes when it bred. This is why zoos prefer not to breed from crossbred animals.

Artificial insemination is difficult in cats because they are induced ovulators - this means females require the stimulus of mating before their bodies release eggs. Just putting sperm inside them when they're in heat would have no effect - there would be no eggs there to fertilize. To artificially impregnate a tiger, you would have to harvest eggs from a female and mix them with the sperm from a male, then introduce the embryos into the uterus. As with humans, most embryos introduced like this do not survive, and the procedure is very costly.
