Analysis of the microbial population that most often causes mastitis in dairy cows
Languages of publication
Mastitis is the most important disease of dairy cows, affecting the major economic losses of milk producers and the dairy industry around the world. In the work on the basis of data from the laboratory dairy plants analyzed the occurrence of microorganisms causing mastitis. Based on microbiological studies, 1462 milk samples taken from quarters of the cows' udders showed that the most common cause of inflammation was Streptococcus agalactiae, whose strains occurred in 27.77% of mastitis cows. In 18.13% of cows mastitis was caused by Staphylococcus aureus, 14.91% by Eschericha Coli, 8.55% by Streptococcus uberis, and 8.82% did not show bacterial growth during microbiological tests. In order to reduce the occurrence of mastitis, appropriate hygiene should be followed during milking of cows and, in the case of disease, cows udder milk should be tested to identify the microorganism causing inflammation and prepare appropriate antibiotic therapy.
