A32-lancaster Farming Saturday, January 23, ,I£BB Garner Speaks At Berks READING Sub-clinical mastitis is an invisible thief that robs dairymen of thousands of dol lars every year, according to Dr. Charles Gardner, a veterinarian and farm columnist. “A cow with a somatic cell count of 600,000 produces three pounds of milk a day less than she would if her cell count were at 150,000,” Gardner told a group of about 100 dairymen Wednesday at the annual Berks County Dairy Day. Gardner, a graduate of the Cornell School of Veterinary Medicine, has a practice in Ackcr manville, Pa. Dairy Day is sponsored each year by Berks County Extension. Gardner’s appearance at the edu cational event was sponsored by the Agribusiness Lending Depart ment of Meridian Bank. Meridian also used the occasion to formally launch the "Ag Letter,” a quarterly publication which will go to far mers and agribusinessmen in the 10 counties of Southeast Pennsylvania. Gardner said sub-clinical masti tis - the kind that can’t be seen - costs dairymen much more than the diseases clinical form, which is readily evident in milk from afflicted cows. “A realistic goal for a somatic cell count is 150,000,” said Gard ner. “Herds do achieve this goal, and your herds can, too. If your cell count is 300,000, you might think you’re doing a pretty good job, and you are. “But each cow is giving you a pound and a half less a day than she would be producing at a cell count of 150,000. At a cell count of 600,000, your cows are producing three pounds less a day than they could be.” BLOWN INSULATION Cellulose & Fiberglass Ceilings, Sidewalls.

Gardner asked his listeners to call out the causes of mastitis. They responded with; Stress. Bac teria. Equipment. Injuries. Weath er. Environment. Even “people” were listed as a cause. Gardner raised a laugh - one of many when he said, “It’s been said that mastitis is a disease of people that shows up in their cows.” Mastitis can be triggered whenever bacteria enter the teal canal, he said. Damp weather, dir ty housing and poor sanitation in the milking parlor can all contri bute. He told the dairymen they should wash their cows’ udders with clean towels - one towel per cow. Udders should be dried after they’re washed and before the milkers are attached. He advocated Dairy Day a pre-milking teat dip in herds with mastitis problems, and a post milking dip in all herds. He also stressed the importance of keeping milking equipment in lop working order. Gardner’s mastitis talk was one of two he gave on Wednesday. He also talked about the use of ani mals records.
