A dairy herd in the state is facing an outbreak of viral pneumonia of unknown origin, according to Maine Organic Farmers and Gardeners Association. The herd has been closed for years, and cows are bred artificially, so the outbreak apparently originated off the farm.
Pneumonia isn’t a disease that only affects young calves, and this is the season for outbreaks, as the weather fluctuates and the agricultural fair season draws to a close. So, MOFGA strongly urges producers to consider cooperating with their veterinarian to build a vaccination protocol for pneumonia and/or to make sure their herd is up to date on boosters. Most vaccines cover IBR, BRSV, PI3 and BVD.
IBR and BRSV have been known to attack adult cattle, often causing abortions, and are not treatable with antibiotics. IBR has a high morbidity/mortality rate and affects milk production and future fertility.
Farmers can take other measures to reduce the risk of infection. Make sure barns are properly ventilated, even on cold, rainy days. Turn on fans above the backs of cows to keep air circulating.
Set up a boot wash station with signs describing how to use it. MOFGA recommends using a sanitizing scrub such as Ster-Bac Quat, or chlorhexidine (follow the directions on the bottle for dilution rates). It does not recommend using bleach, as its disinfecting power can become compromised quickly by excess matter such as dirt and manure.
In addition, wash hands with hot water and soap, and change clothes and shower after visiting other farms and before entering your own barns.
