To continue the Panda conversation here;
In most cases too it has been rare to have two unsuccessful breeding pairs in a row, so Adelaide does have history on their side in this case!
In some instances, but in most Western zoos that have had successful breeding - with only a single breeding pair. For instance, 5/6 of the facilities in North America bred pandas successfully (with one breeding pair at a time). However in Europe there's been a lot more on and off success, with some facilities having success with their pairs and others didn't.Yes I know, hence why I used them as an example. Pandas are not an easy keep species, especially when you consider that even with elephants and people thinking monarto is to dry, asian elephants inhabit the dry grass and semi arid areas of India as well, like the Gir forrest. And are adapted to this. Pandas are not adapted for weeks where night time temps are above 30 degrees C and will need there complex cooled for 6 months of the year. There actual costs, plus the costs to grow and secure food, plus the 1mil to china annually to keep them. Makes them more expansive than a large herd of elephants.
This Is the issue, from the reading (limited) I have done. It seems keeping multiple males on site works better than having just one. Which seems to be the issue in zoos. You either get a dominant enough male for the female to accept or she decides no and its game over red rover. Then you Delve into using repro sciences which are not overly cheap for a species that isnt easy to use AI on. Even elephants are far easier to achieve pregnancy with AI.
