Besides dietary supplementation, vaccination is another way to control mastitis. Several tests and experiments have shown thatStaph. aureus vaccines can be used in heifers to prevent new infections. According to a study, the number of quarters showing chronic intramammary infections during pregnancy was reduced by 43.1 percent. The rate of new intramammary infections during pregnancy was reduced 44.8 percent. Finally, the rate of new intramammary infections at freshening was reduced 44.7 percent. These studies represent possible prevention strategy that may be a major control for managing Staph. aureus.
It is important to keep ahead of heifer mastitis. Knowing what steps to take and how to properly treat can be the success or failure of your incoming milking herd.
