Abstract
Background:
Statistics indicate that fresh dairy product consumption in Indonesia will increase to 3.82 kilograms per capita by 2030. To meet the increased public demand for milk, dairy farmers must enhance their milk production and prioritize milk quality to ensure adequate nutrition for the public. Mastitis is a factor contributing to the low production and quality of milk. Mastitis is an inflammation of the udder that can be caused by infection.

Aim:
This study aimed to determine the prevalence and risk factors of mastitis in dairy cows at Guranteng Dairy Farm, Tasikmalaya, Indonesia.

Methods:
This research was a cross-sectional study. The study was conducted on 45 lactating cows and 45 dairy farmers. Data were collected through direct observation and farmer interviews. Mastitis status was assessed using the California Mastitis Test (CMT) and visual inspection of cow udders. Risk factors were further explored through interviews with the farmers. The statistical analysis was performed using chi-square and logistic regression.

Results:
The prevalence of mastitis in dairy cows in Guranteng reached 47%, 20% clinical mastitis, and 27% subclinical mastitis. The risk factors significantly correlated with mastitis at Guranteng Dairy Farm were age, stage of lactation, parity, udder position, udder washing before milking, washing hands before milking, cleanliness of milker’s nails, and cleanliness of milker’s clothing.

Conclusion:
Farmers are encouraged to implement targeted education programs on preventing mastitis in dairy cows, enforcing proper milking sanitation procedures, and integrating regular udder health monitoring into farm management practices, thereby enabling them to achieve milk production rates and contributing to maintaining food safety and security.
