Mastitis survey in Bolivia.
Quarter milk samples were taken from 1,090 cows on 24 dairy farms in southeastern Bolivia. Nineteen per cent were positive in the milk quality test for subclinical mastitis, 12% for presence of potentially pathogenic bacteria and 4% for both. The prevalence of infection was related to management factors.
