moreThe objectives of this work were: 1) assess in the properties, the operation of 11 milking
systems by checking air intakes, frequency pulse and massages per minute, vacuum production and
lubrication of the pump, 2) determine the percentage correct answers to three multiple choice questions:
How many massages by the minute liner should perform to remove the milk?; Which water temperature
is recommended for washing the milking with alkaline detergent?; And each how many milkings is
recommended to change the liners rubber? 172 farmers were interviewed, of both sexes, in a field day of
cooperative Copagril, and both properties as producers surveyed belong to microregion of Marechal
Cândido Rondon, in west of Paraná. In measurements of milking, it was observed that 55% had anormal
air intake in the system, 64% had frequency per minute above of the recommended, 73% had vacuum
measured below the rated capacity of the pump and another 9% were measured above the vacuum rated capacity. The percentage of correct answers to three questions were less than 50%. It was found that most
producers do not achieve appropriate maintenance of the milking, and this results in malfunctioning of the
same. The answers to three questions revealed that the producers need more technical information and
training on the operation, maintenance and adjustment of milking, in view of the importance of this
equipment daily to perform a proper milking and to getting milk with low microbiological count.
