Study on Quality of Raw Milk in Smallholder Dairy Farms in Jimma Town,South-Western Ethiopia
A cross-sectional study was carried in Jimma town,western Ethiopia to assess the milk quality in 47 dairy herds during the months of December 2009 to January 2010.Bulk milk samples were collected from all 47 dairy herds once in a week for four consecutive times.Somatic cell count,total bacterial count,coliform count and antibiotic residues tests were performed using standard laboratory procedure.Bulk milk somatic cell count (BTSCC)was measured by using Delaval Direct Cell Counter (DCC)while enumeration of total bacterial counts (TBC)and coliform counts (CC)was done by inoculation on Petrifilm plates; antibiotics residues in milk was also determined by using Copan Milk Test (CMT).The geomean SCC in bulk milk was 6.25×105 cells/mL and the mean total bacterial count and coliform counts was 9.62×105 and 2.26×105 CFU/mL,respectively.A positive antibiotic residue was recorded in 55.3% of the studied herds.Significantly higher correlation was observed between TBC.and CC (r = 0.71,P<0.05 )of the milk quality parameters.The study revealed that milk produced in the study area is of poor hygienic quality and with antibiotic residues and for this reason raw milk should be used at least after boiling in the study area and farmers should get awareness on the negative effect of antibiotics on public health.
