Simple question...
 

I know that this is going to seem like a ridiculously simple question to most of you, but can someone please tell me what the REAL definition of a brood mare is? Is it a mare who can be used for breeding or a horse that is actually pregnant?

Thanks!

just a mare used for breeding, doesn't have to be pregnant :)

Thank you! :) That's what I thought, but someone else was disagreeing with me!

Pretty much. Some people have broodmares and then stop breeding them to ride, or retire them.

Used for breeding.
