in dairy cows by using California Mastitis Test (CMT) and
microbial cultuer of positive California Mastitis Test milk sample .
880 quarter milk samples of 220 healthy cows were te
sted using ()
followed by bacteriological examination to identify the major

Thirty native Awassi yearlings, without previous pregnancy or servicing
were used to study the level of somatic cell counts (SCC) in milk and their
relation to the other methods for detection of subclinical mastitis during the
first lactation .
T
hese results confirmed that SCC in milk and CMT can be used as reliable
methods for detecting subclinical mastitis in Awassi ewes . ER and percentage
of lactose are less accurate than CMT in detection of subclinical mastitis.
