Speakers at NMC meeting emphasize technology, research
The 41st annual meeting of the National Mastitis Council provided information on new and exciting opportunities in the areas of mastitis control and prevention. More than 400 attendees enjoyed the presentations and festivities at the meeting, Feb. 3-6 in Orlando, Fla. Year in review Mastitis prevention goes high tech If successful, incorporation of the lysostaphin genome could help protect cows against intramammary infection with Staphylococcus aureus. Although it appears that the scientific techniques exist to produce transgenic cattle that have increased resistance to mastitis, the public debate on the health and safety of these procedures and the products obtained from genetically altered animals will have a major influence on the acceptance and applicability of this technology. One of the sessions provided information on the periparturient period of cows and the effects that various factors such as nutrition and management during this stressful period have on the immune system of cattle. In another session, speakers discussed the use of vaccines developed against pathogenic bacteria to prevent or treat mastitis in dairy cows. Amid all the information about antigens and antibodies and bacterial cultures, several speakers provided details of the management techniques they use in their daily operations to minimize stress on dairy cattle so that the cattle will remain healthy and produce high-quality milk. Changes in SCC limits The debate over the acceptable limit of SCC may be raising concerns about the safety of our milk supply in the minds of U.S. consumers. Therefore, a task force has been formed to evaluate the NMC stance on this topic and provide guidance. The NMC hopes to include members of regulatory agencies and milk cooperatives as well as those involved in research and veterinary medicine in its quest to provide dairy consumers with a wholesome product. Additional highlights The National Quality Awards Program, in its second year under the NMC banner, drew 52 nominations. Jim Dickrell, Monticello, Minn., announced the four regional winners and the national winner, Meekhof Dairy in McBain, Mich. The National Mastitis Research Foundation also was in the spotlight. Dr. Keith Sterner, Ionia, Mich., announced the presentation of the second research award. A grant in the amount of $7,500 was awarded to graduate student Dr. Fiona P. Maunsell and faculty member Mary B. Brown, PhD, Department of Pathobiology, College of Veterinary Medicine, University of Florida. The title of their research project is "Mycoplasma bovis mastitis: the influence of strain of organism on disease expression and localization within the mammary gland." The auction held during the NMC reception was a gala affair. Dr. Jim Jarrett's fast-paced chatter loosened the purse strings of several bidders. The auction raised $2,900, which will be used to replenish the coffers of the National Mastitis Research Foundation. New leaders Other officers elected at the annual business meeting were Dr. Andy Johnson, Seymour, Wis., first vice president; Dr. Leo Timms, Ames, Iowa, second vice president; Dr. Paul Rapnicki, St. Paul, Minn, secretary; and Dr. Pam Ruegg, Madison, Wis., treasurer. | |
