It's the herd (singular) that's doing the migrating. "Of cows" is a qualifier for herd, i.e. if you leave out "of cows" the sentence becomes "a herd on their annual migration" which is clearly wrong. So technically "its" is correct.

But you knew this, you tease!

Hmm. You might just be correct in grammatically precise terms :-) ... but 'a herd on their annual migration' isn't too displeasing to the ear, as we know that 'herd' is a collective noun ... I think.
