House cows were not fed expensive dairy feed just a few generations ago; why is it so important now? House cows can exist, do well, and produce milk on just good grass and hay; at what point of production does graining the house cow become economically profitable for the small holder producing milk for their family? If, for instance, a house cow averaged 5 gallons a-day milk over a 305 day period with the addition of expensive dairy feed, but the same house cow could produce an average of 2 Â½ gallons a-day over 180 day period fed only grass and hay, would it not be advantageous to the small holder to kept a second cow bred to freshen as the first cows’ milk failed? Considering 5 gallons of milk per day far more than most families can use, the hay for the second cow would cost less than the dairy feed for the first, and there would be an additional calf to sell yearly. As it is, here at Wolf Cairn Moor, the milk we sell from one cow more than pays for the grain needed for six head of cattle, so our costs are not out of pocket, but one never knows what the future will bring, and not everyone out there is in our fortunate situation. Besides the subject seems a good opinion generator.
