To prevent environmental bacterial infections, maintain good sanitation by minimizing exposure of teat ends to environ- mental organisms. Action of immunological agents such as leucocytes and lactoferrin is enhanced within the gland, reducing the risk of infection. However, the low risk does not preclude use of good sanitation and watching for flare ups at this time. Also, with the onset of gland secretory activity, the intramammary environment is highly conducive to bacterial growth. Antibiotic concentrations from dry treatment fall below the level required to prevent new infections at this time.
Prevention depends on good sanitation and minimizing the exposure of teat ends to bacteria.
If this happens, consult the herd veterinarian for treatment and handling procedures. Also, consult the veterinarian about all phases of mastitis control. An integrated approach to mastitis diagnosis and control is essential. Therefore, preventing dry period infections is a major key to mastitis control in the dairy herd. Past literature and promotion of dry cow therapy products have led the dairy industry to a false sense of security when using these products.
