Electricity in the Production of Quality Milk

There are two parts to the production of quality milk: The first is that the dairyman must start with quality milk, and second, the milk must be kept good. No amount of equipment, or doctoring, will make good milk, butter or cheese from poor milk. Assuming that the farmer has good cows, and that by good management they produce good milk, what tools are available to help him keep that milk good and put a quality product on the market? There are many in this modern age. Good barns, properly designed milk houses, reliable feed and milk handling equipment, and efficient cooling and sterilizing facilities are only a part of the list, I am naturally interested in the part that electricity plays, or may play if given an opportunity, in the production of quality milk. Garver discusses pasture irrigation, electric fences, feed grinders and mixers, water systems, milking machines, coolers, and sterilizers.
