Al4—Lancaster Farming, Saturday, March 1,1950 Mastitis, prostaglandin featured BY PATRICIA GREEK DOVER The annual York County Dairy Day program was held Thursday, February 21 at the Dover Fire Hall. The program began with Steve Spencer, Penn State extension dairyman, speaking on mastitis control. According to Spencer, the most prevalent form of bacterial mastitis is Strep A. This type is highly con tagious and immune to many mastitis treatments. All forms of bacteria that cause mastitis enter the udder through the teat end. They normally live only in a cow’s udder, but can live on a human’s hands for 48 hours. Thus, the infection can be transmitted from one cow to the next. Spencer noted that teat dipping does influence mastitis control. A study was made using 19 herds that used teat dip and 10 that did not. There were fewer cases of mastitis in the dipper herds than in the herds that were not dipped. Dry treating a cow also helps, Spencer said.
