Patrick- yes, if they have collected semen from Torgamba it may prove useful somewhere down the line- its a great shame they haven't been able to breed from him. Unlike Port Lympne's two females, he was a much younger animal but it seems both at Port Lympne and later at Way Kambas he has had older/non fertile(?) partners. Now they have young females at Way Kambas,it seems too late for him as he isn't in 100% good health anymore. Its all enormously frustrating. Perhaps with Andalas, Rosa & Ratu things will finally come together as these three are all perfectly aged for success....
Mark- no, it wasn't Port Lympne's fault really they failed with the Sumatrans. They certainly feed their animals(all species) a better diet than just about any other zoo- no expense was spared with their care either. The 2nd female was called Meranti- after she died I think the post mortem showed the usual tumours in her uterus etc indicating yet another elderly female. The irony is that Torgamba was a relatively young male in those days.
It seems many of the females which were captured and then randomly dstributed among the zoos during the 1980's turned out to be elderly so those zoos were doomed to fail right from the start. I think seven went to the U.S. but by chance only Los Angeles got a young female- Emi, and an older male which died, so Emi was then 'loaned' to Cincinnati who had the only remaining male- Ipuh (plus Rapunzel, another elderly female). You know the rest....
