I know that "a herd of cattle" and "many herds of cattle" are correct, but what about "cattle herds"? For example,
We drove by cattle herds.
Is that grammatical?

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. If this question can be reworded to fit the rules in the help center, please edit the question.
"Cattle herds" would be ok because it is specifying the type of herd with the word, "cattle," acting as a modifier. It's just like, "cement road," or, "glass wall."
