dc.description.abstractMilking operation is the major activity of every dairy farm affecting the quantity, quality and the cost of the milk produced. This study was envisaged to compare and evaluate electrical milking machine (T1), hand milking (T2) and manual milking machine (T3), on crossbred dairy cattle. Fifteen freshly calved crossbred dairy cows were randomly selected and allotted to three different treatment groups adopting switch-over design. The cows were milked for 60 days both in the morning and evening sessions. There was no significant difference in the average daily milk yield obtained by different milking systems. The average total retained milk was significantly (P <0.01) higher in T3 compared to T1 in both the milking sessions. The average milk extraction rate was significantly (P <0.01) higher in T1 (i.e. 1.26 ± 0.10 kg/min) compared to T2 and T3 (0.69 ± 0.04 kg/min and 0.66 ± 0.05 kg/min, respectively). 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. The mean average electrical resistance of milk was significantly (P <0.01) higher in T1 and T3 compared to T2. The physiological parameters of the milker (Blood Pressure, Heart Rate and Respiratory Rate) compared before and after milking revealed that, the stress undergone by the milker was higher in T2 compared to T1 and T3. 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 bacteria in milk was significantly (P <0.01) higher in hand milking (T2) (456.867 ± 37.838 x 103 cfu/ml) than in T1 and T3 (280.70 ± 30.428 and 312.93 ± 29.705 x 103 cfu/ml). The study revealed that, hand milking caused much stress to the milker and the microbiological quality of milk was poor. The cost of milk production was least in T3 compared to T1 and T2. The Electric milking machine was found to be superior in terms of quality of milk and ergonomics of milking. However, Manual milking machine, intermediate in terms of cost, quality and ergonomics, can be recommended for small holder dairy farmers with the benefit of cost effectiveness and improved milk quality than hand milking. Key words: Milking systems, ergonomics, milk quality, hand milking, machine milking.en_US
