Abstract

A total of 115 dairy cows were screened by California mastitis test  (CMT) to estimate the prevalence of subclinical mastitis in a dairy herd in Beni-Suef Governorate, as well as Somatic cell count ( SCC) of 28 bulk tank milk samples were estimated using De-Laval cell counter. Mean bulk tank SCC (BTSCC) was 9.5 x 105  +   7.5 x 104    with the highest frequency of distribution (64.3%) lies within the range of 5x 105 to 1 x  106 . The prevalence of subclinical mastitis was 15.2 % on an udder quarter basis and 39.1% on a cow basis. The organisms that were most frequently isolated were E.coli (35.4%), Str.bovis (21.5%), Str.agalactiae (10.8%), Coagulase negative Staphylococci (CNS) (7.7%), S.aureus (6.2%), Str.dysgalactiae (3.1%) and Str.faecalis (3.1%) for single infection while for double infection were Str.bovis with S.aureus (6.2%), Str.bovis with E.coli (3.1%), Str.agalactiae with S.aureus (1.5%) and Str.bovis with CNS (1.4%). In conclusion subclinical mastitis is a serious problem in dairy industry and its early detection is the corner stone in its control.
