Ultraviolet on a dairy farm

At Broadacres Farm in Lebanon, N. J., extensive use of ultraviolet radiation is reported to be producing milk of a superior quality — a bacteria count of less than 1,000 per cubic centimeter whereas grade A pasteurized milk allows for 30,000 bacteria per cubic centimeter and grade B 100,000. Two two-hour sunbaths per day — one beginning at five in the morning and the other beginning at six in the evening — are given to all milk cows through the medium of S-4 lamps hung o n six-foot centers eight feet above the floor down the main aisle of the barn.
