I didn't see your latest reply when I posted my response. But upon reading your latest post, she definitely knows that she's the dominant one and knows she can get in your space even when uninvited. No doubt you thought it was "cute" before when you first got her that she did that, but now it's not so cute since she's a bit bigger. So, not only do you need to be more assertive, but persistent and consistent in teaching her some manners. And you really have to mean it when you holler at her or chase her away. I know you probably already think you mean it when you tell her "No!" and push her away, but if it's kinda half-hearted and you feel sorry or guilty after for being so mean to her, then that in itself loses the effectiveness of the training. It's completely counter-productive, and certainly not helping your situation.
Also, cattle are not horses. Cattle use their heads to push each other around, unlike horses, so simply pushing on her chest and telling her no is, as I mentioned before, just encouraging her to play more with you. You will have to do or say something to scare her and shock her into realizing that you don't want to play with her--and that might meaning having to raise your voice and holler something harsh at her.
