The major aspects influencing parlour throughput: How fast cows enter the parlour How soon units are attached How soon peak flow rate is achieved after unit attachment How soon units are detached
Milking Phases The milk flow during the milking of a properly stimulated individual cow can be speculated as having 5 phases .
Phase 0 – Start-up from attach to first flow – cisternal emptying?
Phase 1 – Rise up from first flow to peak flow
Phase 2 – Peak flow: peak (plateau) milk flow
Phase 3 – Slope down post-peak, still above take-off settings
Phase 4 – Dribble waiting for take-off to function
Take-Off Settings
The ability to adjust take-off settings varies from manufacturers. There are two general settings: minimum flow before automatic detachment and maximum time before detach.
Because of the difference among the manufacturers The National Mastitis Council is looking for a standard definition for unit-on-time, peak flow, duration of time in low flow, and a standardized method of evaluating take-offs.
Currently, we use the following:
Unit-on-time Total vacuum-on duration (not dump-to-dump)
Peak flow Average flow rate (total yield) during the second minute
Time is low flow Total duration with flow less than 1 kg per minute
Operation of Automatic Cluster Remover
Decrease the take-off wait time to 5 second, and then make gradual increases in the take-off flow rates. If the maximum unit-on-time can be controlled, starting at 10 minutes is probably safe. Some manufacturers do not have this- facility Continue decreasing maximum unit-on time and increasing take-off flow rates on a weekly basis until no further improvement is seen. Eventually, once the proper functioning of the take-offs has been substantiated, the milking vacuum level can slowly be raised.
