ONLY HIGH GRADE | MILK WORTH WHILE Poor Quality Production to Be Avoided.

York State Experiment Station. * WNU Service. Meeting the bacterial count requirements for premiums on grade A milk is proving profitable to many New York state dairymen in these days of low milk prices. A first premium is paid on milk with 10,000 or less bacteria per cc and a second premium on milk with a 10,000 to 25,000 count. In one large grade A plant in this state, last June, 60 per cent of the producers deceived the first premium, 20 per cent the second, and 20 per cent no premium. This last group lost about $1,600 in premium money for that month alone. 1 Accurate information on the common sources of bacteria and dirt in milk Is essential for the dairyman who is trying to produce high grade milk. The results of studies show that the average healthy udder produces milk with a bacteria count less than 1,500 per cc, while infected udders may contain hundreds of thousands of bacteria per cc. The number of bacteria added to milk from the dirt that appears as visible sediment under clean conditions is less than 100 per cc, but under dirty conditions it may reach 15,000 to 20,000 per'cc. Dust in the barn adds less than 10 bacteria per cc under average conditions, but it shows as sediment and should be avoided.
