Influence of milking techniques on microbial condition of milk and incidence of mastitis

One hundred random samples of cow and buffalo handand machine milking (25 of each) were collected from differentlocalities at Sharkia Governorate, Egypt in a sterile bottle andtransferred to the laboratory in ice-box to maintain its chemicaland microbiological status unchangeable. Each sample wasmixed thoroughly before being divided into three parts. Thefirst was examined for incidence of mastitis, the second forchemical examination, while the last one was used forbacteriological examination.The results of CMT reveal that 12(48%) of the examinedcow hand milking samples were negative and 13(52%) werepositive while in case of examined cow machine milkingsamples 11(44%) were negative and 14(560/0) were positive.In case of buffalo milk, the results show that 15(60%) ofthe examined hand milking samples were negative and1 0(40%) were positive while in case of examined machinemilking samples 14(56%) were negative and 11(44%) werepositive.The MSCC/ml. was studied and reveals that negativesamples contained less than 4x 1 05 MSCC/ml., while thepositive ones contained higher numbers of MSCC exceeded5xl06/ml.The chemical examination of normal and mastitis cowhand milking samples reveal that the mean values of fat%,protein%, lactose%, SNF%, minerals% and chlorides% were
