Yep the vulgar term "herd" can be used to name a group of cattle, but I love the word "kine" when referring to groups of domesticated animals. "Herd" also describes groups of wild animals.
i worked on a dairy farm when i was 14 and 15...then I got smart.
The owner was a helluva good man and called his cows a kine.
But then I went to work for a beef ranch and there we called em "herds" because they were "freer" animals.
