Intramammary infections and somatic cell counts in meat and pelt producing ewes with clinically healthy udders

To conclude, one third of Swedish meat- and pelt producing ewes without clinical signs in the udder had IMI in one or both udder halves at weaning and or after lambing, and CoNS was the most common bacterial finding. A high SCC (≥400,000-500,000 cells/ml) was associated with IMI and a difference in having a high (CMT 3-5) or low (CMT 1-2) between udder halves can be used as an indicator of IMI under field conditions.
