Studies on the bacteriological quality of farm bulk milk in giza governorate

studying bac t e.r i.o Log i c a I quality of farm bulkmilk produced in Giza Governorate, one bundred buffalo’smilk samples were collected from two farms (eacb 50 samp-les) in Giza Governorate. Sampling was done every two weeks from morning milk.Collected samples were subjected to bacteriolgical examination, as well as keeping quality tests (aciditypercentage and dye reduction tests).’I’he results of bacteriological examination revealed that, t he total colony count/ml. ranged from 1.2 x 105to 8.1 x 107, w i t h a mean value of (’8 x 105 + 14 x 105•The t her modur i.c count/ml. varied from 3.1 x 102 to9.1 x 105 with a mean value of 114 x IcY +19 x IcY.
