As a volunteer zookeeper at a mid-sized, AZA accredited US zoo, I think this is all a bunch of malarkey. We have our lions, tigers, and giraffes on birth control, and there are only 1 mated pair of each species at our zoo to care for. I have seen no ill effects on any animal on contraception. To allow giraffes or any zoo animals to "do as they do in the wild" and indiscriminately breed is poor, lazy and careless animal husbandry practice, to put it very mildly.

Why are the giraffes not given contraceptives?
In Copenhagen Zoo we let the animals breed naturally. With naturally we mean that they will get young within the same intervals as they would in the wild. That means that the animals get to carry out their natural behaviours. Parental care is a big part of an animals behaviour. It is a 24 hour job in longer periods of their lives and we believe that they should still be able to carry out this type of behaviour also in captivity. Contraceptives have a number of unwanted side effects on the internal organs and we would therefore apply a poorer animal welfare if we did not euthanize.[/QUOTE]
