Mastitis Management:  Don’t Forget Your Heifers!  

Dairy heifers represent a major investment in a dairy herd’s future genetics, production, and financial welfare. Prevention and treatment of mastitis in all ages of heifers is crucial to your farm’s future profitability. Many times, heifers are forgotten on the farm. They live away from the main farm where they are not cleaned and bedded as often as the milking herd. This can cause huge mastitis issues when they become a productive member of the milking string.  Read more.
