That's a good point. I'd also say that Holstein cows are pretty scary; a cow can flip from "this human is fine" to "I'm going to protect my calf by trampling this human to death" with barely any warning. Factors like floor material also matter. On wet concrete, work boots have decent traction but bull hooves don't, so a bull with a nose ring is a little bit less of a threat. On dirt or dry manure, though, watch out.
