I always called my cows (and they were cows, not cattle) with "Ho Boss"
And it is amazing watching a 1 ton cow (old genetics Simmentals when we first started out in the early 90's) come running down the steep hill in the back pasture - which we called the "back 40" even though it was just a 12 acre pasture - when I would step outside my door and yell "Ho Boss".
And they were cows in Wisconsin, cattle in Nebraska.
And my sheep were "sheeps" ('cause it was fun).
I no longer farm now
