(@Vadia) Are you contradicting Wikipedia, there? (How could you!! Everyone knows Wikipedia is infallible!!
)
Anyway, milk or beef cattle differ, generally. Beef cattle are going to be particularly large. Because you want a whole lot of beef. It's in the name. (A beef bull is a sight to behold. At a safe distance, or behind a barrier you actually trust.)
Dairy cattle may be smaller because of various other selective pressures. But, while I haven't
weighed any dairy cows recently (or even tried to tip them) they're still
big. I can believe the weights quoted.
I was actually
in a field of cows a few weeks ago[1][2], and I think I can guarantee that they were in no way small. And these were hill-raised cattle, smaller than even a good milker, as seen elsewhere.
I may have photos to share. Although I doubt any of them would convey scale (let alone the product of volume and density, required to convey the weight). And somewhere I've got one of a sheep that looks like a cow. Really, it did. Only smaller. (Shortly after that, I nearly got caught in a sheep-stampede, which is bad enough. But nothing like a cow stampede could be.)
[1] One field amongst several, through whose open gates they openly wandered. Never mind why I was in there, it's largely irrelevant to the discussion at hand, save that I made sure I had a reasonable chance of getting to, and over, a nearby fence if any that were wandering through looked like they might take exception to my presence. With the privilege of a fence betwixt me and them, I even managed to pat one on the shoulder.
[2] Wait, I was also in a field of cattle last
week! How could I forget. This was a much more hilly field, with very long grasses, and I think the cattle were of the smaller kind, more capable over hilly ground, but I kept an eye on the herd at the other end of the field, for much the same purpose as with footnote-1, of course. I had no doubt they'd come charging through the vegetation faster than I could run, should they have been so inclined. (I was trusting that they weren't going to be so devious as to send a separate unit of attackers through the gate into the next field, should they attack, that next field being my only practical "over the fence" option until I got back to the farm-track at the bottom of the slope.)
