I couldn't tell you how many, but the large enclosure was called the Kob Meadow (but a year later it was the Ugandan meadow). I vaguely recall seeing at least half-a-dozen including a calf, but there could easily have been more in the vegetation that I couldn't see.
No, I stopped compiling lists at zoos a long time ago, except for wild animals (mainly birds). But I do take lots of photos of anything unusual or noteworthy (if it's visible, of course).
