This study concentrated on the effect of different groups of milking systems installed at Estonian dairy farms on the free acid (FFA) content of farm bulk milk. Dairy farms supplying two Estonian dairies were included in this study. Bulk milk samples were taken from August 1999 to June 2000 from all farms supplying Dairy Imonthly and twice during the period from January 2001 to May 2001 from the largest farms suppling Dairy II. Free fatty acid content was determined using the "copper soap" method. Milking systems used on farms of the Dairy I were divided into eight groups to evaluate the effect on FFA content: 1)new milking parlours - installed after 1994; 2)old milking parlours; 3)old pipeline milking systems with a long milkline - incorrectly installed system with 1...4 vertical ascents; 4)reconstructed milking systems with a long milkline - old equipment with proper slope and removed vertical ascents; 5)new pipeline milking systems installed after 1994; 6)properly installed pipeline milking systems with a short milkline; 7)bucket milking, milk transport from shed to tank by milkline
