Activation of lipolysis during milking normally results from faulty design and installation, and inadequate maintenance of milking equipment, and is associated with excessive air intake into the system, causing turbulence. Majority of pipeline milking systems used in Estonian dairy farms have been installed in 70s and 80s. Their mounting does not meet the requirements of ISO 6690 and 5707. In resent years besides installing of new milking equipment, the reconstruction of old ones has been started. There is little information on the effect of that kind reconstruction of old ones has been started. There is little information on the effect of that kind reconstruction on raw milk quality. In this study the effect of three factors on induced lopolysis were investigated on original laboratory experimental equipment. The parameters of studied factors - the time of agitation, the intensiveness of agitation and the rate of aeration were changed independently. A preliminary study showed that with great probability there are different weights and not linear relation between these three factors. Aeration rate was mainly responsible for the increase FFA content of raw milk
