Trend in cow mastitis pattern in Croatia

Cow mastitis is a permanent problem in dairy production due to several reasons such as plenty of possible pathogens, possibility of transmission among cows, contaminated cow environment, highly producing cows prone to infection etc. Total of 385 cows from 15 farms were included in the research. Farms were visited at evening milking time during the period from February to April 2015. Samples for bacteriological examination were taken from previously prepared udder quarters of all lactating cows at the time of visit and transported to the laboratory on ice. California mastitis test and bacteriological examination were carried out according to the National mastitis council recommendation. Obtained data concerning the occurrence of udder infection, occurrence of pathogens, distribution of infection among quarters was compared with results from similar researches formerly carried out. CMT positive reaction was noticed in 211 (13.7%) individual udder quarters. 145 out of 385 (37.3%) cows had at least one CMT positive or permanently dried off quarter. From 175 udder quarters (11.56%) mastitis pathogens were isolated. Among 363 cows with all functional udder quarters, 106 or 29.2% had at least one infected udder quarter. The most commonly isolated udder pathogen was Staphylococcus aures (69 or 4.56%), followed by the group of streptococci (37 or 2.44%), Trueperella pyogenes (26 or 1.7%) and Corynebacterium spp. (26 or 1.6%). There was no statistical difference in the level of infection between front and rear udder quarters. CMT results and results of microbiological examination were moderately correlated (Kappa coefficient 0.4662). Positive trend in udder health is obvious if results are compared with the results of former similar researches carried out 1997 and 2004. CMT positive reactions in those researches were noticed in 34% and 28% of examined quarters. Mastitis pathogens were isolated from 21.5% and 22% of quarters, respectively. Conclusion. Udder health improvement in cows on Croatian dairy farms is influenced mainly by adoption of EU legislation regarding milk quality whose implementation in Croatia started in 2001.
