[Determination of the cell count in sheep's milk]

A prospective study was done to examine the extent to which the 'regulation concerning the method of examining milk using the Coulter counter' was also applicable to sheep's milk. This was found to be the case, provided the milk is previously mixed with a Vortex mixer for 0.5 minutes. In view of the studies done by others, the threshold value was reduced to 4.5 mu. The levels recorded by this method were readily reproducible. Any statement regarding the relationship between the cell counts recorded and the cells actually present in the milk cannot be based on these studies.
