A34-Uncast«r Farming, Saturday, March 1,1986 BY ROBIN PHILLIPS Staff Correspondent LEESPORT - “A lot of dairy farmers could increase their production if they would un derstand the mammary system and treat it accordingly,” stated Clyde Myers, Berks County Agent, as he began the program at the Southeast Pennsylvania Ex tension, “Mastitis and Milking Equipment Update” meeting last week. The lineup of experts at the seminar attempted to enhance such an understanding by indepth discussions on mastitis. Going beyond merely stressing the need to teat dip and dry treat, the topics of the meeting dealt with exotic forms of mastitis, milking equipment problems and research, milk recording devices, teat dips and dry cow treatments, somatic cell counts, and new developments in milking equipment. On hand to provide a very in formative presentation and field many questions throughout the day were Dr. Larry Hutchinson, PSU Extension veterinarian, and Steve Spencer, PSU Extension dairy ■aßßaaßHaHaaßßanwaaßHa Dr. George F.

The understanding of somatic cell counts and the use of that knowledge was stressed throughout the day. The somatic cell count (SCC), a measurement of the leukocytes fighting infection in the cow’s udder and present in a milk sample, is provided to par ticipating dairymen on their monthly DHIA reports. The coded results on each cow can give ad vance notice to a dairyman of subclinical mastitis or an on coming infection. At a “code 3” or a measurement of 141,000 SCC, subclinical mastitis is present in the udder, and production loss begins. By a code of “5” or SCC of 500,000, clinical infection is obvious and the loss in production is critical. It is estimated that $75.00 to $160.00 per cow/per year is lost to high SCC or mastitis, and as much as one-half of all dairy cows may be infected in two quarters. It has also been shown that excessive somatic cell levels in milk indicate up to a 25% loss of production potential for the the herd. Myers recommended looking at the herd’s trends over a year’s time. By screening the SCC each month and possibly charting a cross section of the herd, trends in codes may be seen to lead to a problem within the herd. Ac cording to these trends, stated Myers, a dairyman can determine if housing problems, milking system performance, or spreading mastitis is in his herd and costing him daily and substantial losses. High somatic cell counts in first calf heifers when they freshen could be a sign of a sucking problem in group pens, or a housing problem with younger stock. Older cows developing high counts could be spreading mastitis within the herd. If a certain time of the year seems to be leading to higher SCC in the herd, poor housing or muddy conditions could be the source of the problem. A thorough screening of the SCC and the use of the CMT (California Mastitis Test) to determine which quarters are infected can help the dairyman control the problem in FARMERS AgCREDIT 9 EAST MAIN STREET, LITITZ, PA 717-626-4721 WSSBM Enjoy ■ Wm iflr Youngs advantage.

Fewer herd replacements are necessary when mastitis is controlled. Dr. Larry Hutchinson discussed “The Environment and Mastitis.” “A cow can repair (the udder) somewhat after the infection period,” Hutchinson began, “but she can never grow new milk (Turn to PageA3s) • Open Houses • Company Picnics • Private Parties Pig Roast, Ox Roast, and More LANCASTER CO. 717-464-3376 i^yonnii’s Spring Pa 16673^^^ X3»^® Livestock Nutritional Services
