This is going to sound very odd indeed, but would it be possible for people in-situ to somehow get semen from wild bulls and then use this in AI to get captive females pregnant? How possible is this, and could it be successful in trying to make a more diverse group without having to capture any animals from the wild?
This is quite off-topic in general, but relevant to what I was asking above as well, it would be interesting to know. In an attempt to try and get a secure captive population of Javan Rhinos, how possible would it be to take semen from wild bulls and again use this for AI, implanting it in a female Indian Rhino? I know a hybrid scenario would never be ideal, but hybrids are often born healthy and fertile (an example being Sumatran/Bornean Orang hybrids). If they could get a healthy population of hybrids, could it be possible then to selectively breed in an attempt to get a pure specimen. This would save having to remove any from the wild and could possibly bring about a back-up captive breeding programme. As you can probably tell genetics is not my strongest area, and this is probably a massively bad idea. But hey, off-topic
