    Area of Science:

    • Veterinary Medicine
    • Animal Science
    • Dairy Production

    Background:

    • Subclinical mastitis is a significant concern in dairy herds worldwide.
    • Bacterial infections in milk can impact animal health and product quality.
    • Understanding prevalence and risk factors is crucial for dairy farm management.

    Purpose of the Study:

    • To determine the prevalence of subclinical mastitis and pathogenic bacteria in dairy cows in southeastern Bolivia.
    • To investigate the relationship between infection prevalence and farm management factors.

    Main Methods:

    • Milk samples were collected quarterly from 1,090 cows across 24 dairy farms.
    • Milk quality tests were performed to detect subclinical mastitis.
    • Bacteriological analysis identified potentially pathogenic bacteria.

    Main Results:

    • 19% of cows tested positive for subclinical mastitis.
    • 12% of cows were positive for potentially pathogenic bacteria.
    • 4% of cows tested positive for both conditions.
    • A significant association was found between infection prevalence and specific management factors.

    Conclusions:

    • Subclinical mastitis and bacterial contamination are prevalent in Bolivian dairy herds.
    • Farm management practices play a critical role in the occurrence of these infections.
    • Targeted interventions focusing on management are recommended to improve herd health and milk quality.
