Carl, these cows are not hard doing under our management. They might in a different environment but they also might be too easy of keeping in a different environment. As for as calving ease, most of the calves weighs under 80 lbs at birth and in the last 10 years the only calves we had to pull were breach or a map presentation of a foot turned or head turned. It is rare that we pull a calf. Granted we are not running large numbers of cattle and most calves around the first of the year. These cattle are not perfect but they function on Bahia, Bermuda, Crabgrass summer pasture with the same kind of hay in winter and Ball clover in the spring and mineral. We also do not creep feed calves. We average about 1 pair to 1.5 to 2 acres.
