The article describes the cow traffic dynamics from the waiting yard to the milking parlours using mechanical movers. If the mechanical movers are not used, the cows must be driven by the animal breeders – cow drivers, but it is related to considerable consumption of work. In the research it has been stated that the mechanical moversare practically indispensable using the rotary type milking equipment as in this case continuous traffic of animals should be guaranteed to the milking places. To ensure this, in Latvia cow mechanical movers Cow Mander 600/700 are used that gather concentration in the waiting yard up to 1.1-1.2 m2 per animal. Nevertheless, it exceeds the recommended concentration 1.5-1.6 m2 per animal. If the side by side type milking equipment is used with cow group allowance in the milking places, the task of the cow mechanical mover is to reduce the part of the waiting yard occupied by cows concentrating the animals near the entrance into the milking parlour. In that case the mechanical movers can be operated in manual regime ensuring concentration 1.5-3.0 m2 per animal. Usage of such solution reduces the consumption of work necessary for driving cows for about two times.
