No way man, buffalo top out at 35mph and can outrun their hunters. What you see here is a domesticated, overfed cow in a field. Side note: I've seen that vacant gaze before, one of our heifers had it when she got her hoof caught in a groundhog hole during a stampede. Those cows are so fucking stupid they run from the hand that feeds them, hurting themselves in the process, and yet even though they literally live on an open field of food, they still don't eat themselves to death.
