When playing in a survival or (creative) world with, no resource or behaviour packs, and in single-player; breeding animals has an incredibly short cooldown of only one minute compared to the usual five. I have tested this with cows and sheep, exiting and entering has not fixed the bug and the extra baby animals remain.
edit: tested in creative
