Abstract:
This research work was carried out to compare and evaluate the effect of electrical milking machine (T₁), hand milking (T₂) and manual milking machine (T₃) on the quality and quantity of milk produced by crossbred dairy cows. Fifteen freshly calved crossbred dairy cows were randomly allotted to three treatment groups adopting switch-over design. The milk composition, revealed no significant difference in the fat per cent, but significant (P<0.01) difference in Solid-Not-Fat, Specific Gravity and Protein. There was no significant difference in the average daily milk yield obtained by different milking methods. The Somatic Cell Count was more in the milk obtained by hand milking followed by manual machine and electrical milking machine (5.145 ± 0.080, 5.791 ± 0.093 and 5.152 ± 0.094 somatic cells/ml). The Total Viable Count of milk was significantly (P<0.01) higher in hand milking (T₂) (456.867 ± 37.838 x 10³cfu/ml) than in T₁ and T₃ (280.70 ± 30.428 and 312.93 ± 29.705 x 10³cfu/ml).The study reveals that the quality of milk is considerably reduced by hand milking compared to machine milking.
