Verschil in genezing van subklinische mastitis na wel of niet behandelen bij 1e of 2e verhoging van het koecelgetal voor de major pathogenen

By Jan Siebren Duiven


The difference in bacteriological cure of bovine subclinical mastitis for treated and non-treated quarters during lactation after a first or second elevated somatic cell count was investigated for the major pathogens and coagulase-negative Staphylococcus in this study. In total, 772 quarters were investigated during this study, 264 of them where treated. Only intramammary treatment was used. The cure was determined as the absence of the isolated bacteria pre-treatment in the 2 control milk samples, taken 1 and 2 weeks after treatment. Treated quarters had a higher cure rate after a first elevated somatic cell count in comparison to untreated quarters. All treated pathogens had a significant lower cure rate compared to non-treated pathogens. Except for Streptococcus uberis, no significant effect was found for this pathogen. After the second elevated somatic cell count there was over-all no significant difference between cure rates between treated and non-treated pathogens. But for Staphylococcus aureus penicillin sensitive en coagulase-negative Staphylococcus treated quarters after a second attention did have better cure rates then non-treated quarters.\ud Also the factors associated with cure rate where investigated. Attention, parity and the pathogen were significant related with the cure of subclinical mastiti
