I don't know much about heifer behavior, as I don't really deal with the heifers at work until they freshen, and Libby-Belle is the first heifer I've raised. She will be a year old next month. (My, how time flies! :waa: ) OK, so here's the situation/question. L-B has had a lot of attention and human interaction, since she stayed with her momma, who was our family milk cow. She is friendly; I can walk right up to her, pet her, run my hands down her legs, touch her udder, etc. Her mother was a calm and friendly cow. (I have no idea what her sire was like.) The problem is, sometimes when I'm petting her, she'll begin rubbing her head on me. Because she has horns, and because at least in horses, head-rubbing is considered a sign of disrespect, I have been trying to discourage this. If she doesn't stop right away when I say no, I'll tell her to "Back Off!" in a loud threatening voice, which usually makes her jump back a couple steps. Then I'll tell her "OK" and continue to pet her. Recently, this happened when Gary (husband) was out in the yard, and I commented to him that I was worried that L-B was displaying signs of aggression that might be problematic later. He told me I was being silly, and showed me how he "plays" with her by grabbing her by the horns and twisting her head around. She clearly enjoyed this (she was licking him while trying to hook him with her horns!) but it still strikes me as not being such a great idea. He says heifers are not naturally aggressive, though, and there is nothing to worry about. What do you all think?
