The objective of the study was to estimate milk lactose and somatic cells in normal and sub-clinically affected dairy buffaloes under field conditions. Four hundred-quarter samples from 100 healthy dairy buffaloes were subjected to Surf Field Mastitis Test (SFMT), direct microscopic somatic cell count (SCC) and milk lactose content analysis. Twenty quarters positive and negative samples for SFMT were subjected to microbiological examination. Mean milk SCC at SFMT score N (negative), T (traces), first degree positive (P1), second degree positive (P2) and third degree, positive (P3) were 2.06 x 105, 3.73 x 105, 9.69 x 105, 31.97 x 105 and 121 x 105 mL-1 respectively. Mean milk lactose at SFMT score N, T, P1, P2 and P3 was 5.10, 4.81, 4.66, 3.92 was 2.66%, respectively. Out of twenty quarter samples with negative score of SFMT, 16 quarter samples showed no growth; whereas, gram negative cocco-bacilli were also isolated from two quarter samples mi xed growth was observed. Out of twenty quarter samples with positive score of SFMT Staphylococcus aureus was isolated from 10 quarters samples, Streptococcus agalactiae from three quarters, mix growth of S. aureus and S. agalactiae from three quarter samples and from four quarter samples coagulsae negative staphylococci (CNS) were isolated.
