abstract = "The pulsation system of the milking machine impacts milk flow rate, milk harvesting time, udder health and milk let-down, which are important factors in farm productivity and profit. This study investigated the effect of pulsation ratio on daily milk yield, milk flow rate and milking-on time in a conventional milking parlor with a Multi Lactor (ML) milking system, where each udder quarter is milked separately. In total, 170 dairy cows on two commercial farms were included comparing pulsation ratios of 65:35 with the standard pulsation ratio of 60:40. Vacuum level was 34 kPa and pulsation rate 60 cycles/min. 
Total milk yield per milking, average flow rate and machine-on time differed significantly (P0.001) after the change of pulsation ratio from 60:40 to 65:35. However, total milk yield per milking (13.67 ± 0.33 vs. 14.00 ± 0.33 kg) and average flow rate (1.75 ± 0.05 vs. 1.86 ± 0.05 kg/min) increased, whereas milking–on time (8.36 ± 0.25 vs. 8.03 ± 0.25 min) decreased. Moreover, the highest percentage of increase in the average flow rate was 7%, whereas the lowest reduced milking-on time was 40.2 second/milking after the pulsation ratio changed from 60:40 to 65:35. These results depend on the amount of harvested milk yield per milking and show that milking efficiency could be increased by increasing the pulsation ratio up to 65:35 without negative effects on udder health. 
In conclusion, it is possible that an increased pulsation ratio up to 65:35 can be used to increase milking efficiency in conventional milking parlor with ML milking system
