| Abstract: | The objective of the study was to investigate the influence of dairy cow management techniques and milking methods on hygienic
quality of raw milk. Total Bacterial Count (TBC) and Total Coliform Colonies (TCC) were studied to determine the effects.
Investigations were carried out in fifty dairy farms from August 2007 to December 2007. The mean TBC and TCC for the herds
with comparatively good and poor management practices were 0.9 × 105 cfu/ml and 0.2 × 103/ml and 99 × 105 cfu/ml and >180 × 103/ml, respectively. The overall mean TBC (22 × 105 cfu/ml) and TCC (47 × 103/ml) obtained in this study exceeded the internationally recommended levels for TBC (105 cfu/ml) and TCC (<1,000/ml). The overall results obtained suggested that the raw milk tested was of poor hygienic quality
with the presence of a great variability among milk samples. |
