Abstract

Subclinical mastitis continues to be a common issue for small-scale dairy cow farmers in Indonesia. This disease poses significant challenges for farmers as it can lead to a reduction in milk production, resulting in severe economic losses. This study involved 126 dairy cows with lactation periods ranging from 1 to 5, sourced from 29 different farmers, totalling 504 quarters examined. The research utilized a case study method with field exploration conducted in Toyomerto Village, Batu Sub District, Batu City, East Java, Indonesia. The analysis of subclinical mastitis was carried out using the California Mastitis Test (CMT). The findings of the study revealed a prevalence of subclinical mastitis in Toyomerto Village at 69.84% (n=88). Among all the tested teats, 41.47% of them were detected with subclinical mastitis, with the highest prevalence observed in the right hind teats, totalling 27.27%. The prevalence of subclinical mastitis in dairy cows from small farms in Toyomerto Village remains notably high. The continued lack of attention to sanitation and cleanliness remains a primary factor in the high prevalence of mastitis.
