[Cell count and Schalm test results of milk from dairy sheep with healthy udders during the course of a complete lactation].
The somatic cell count (SCC) was determined in 28 milk sheep with normal udder health using the California Mastitis Test (CMT) and a fluoro-opto-electronic cell counter (Partec Counter). The examinations were made at two week intervals throughout the lactation period. 92% of the premilking samples had a negative CMT reaction and in 0.5% of the samples the reaction was distinctly positive. In 95% of the premilking samples the SCC showed less than 200,000/ml and in 95% of the individual total milkings it was less than 350,000/ml. Elevated SCC were common towards the end of lactation when milk yield was low.
