Mastitis poses significant challenges in dairy farming, particularly when it affects pregnant heifers during critical udder development phases. Infections during late gestation can damage developing mammary cells, leading to reduced milk production and compromised udder health. To mitigate these risks, it’s essential to monitor heifers for early signs of infection using methods like the California Mastitis Test or analyzing somatic cell counts.
Implementing environmental controls, such as maintaining clean bedding and calving pens, reduces exposure to pathogens. In certain situations, administering antimicrobial treatments or applying teat sealants may be necessary, despite the additional labor involved. These proactive measures support the biological preparation of heifers for lactation, promoting their long-term health and productivity.
