When you get near to a baby animal it makes its sound as if it was already grown up. In iOS they do sound like baby animals.

with me are the sounds of places and break other than IOS (Ipad, Ipod, etc). and also the baby sounds.
(On Android Tablet)
I´m agree with you that in iOS devices can be heard the Baby Animals sounds. If you saw the Minecraft Pocket Edition 0.6.0 Showcase, Daniel Kaplan was on his Android,and in a part of the video it was a baby cow and it sounds like grown up animals
