SUMMARY
In this study ten machine milked cows (MM) and ten suckled +hand milked (HM) Holstein cows were studied for plasma lipid concentrations. Used blood samples were collected from the jugular vein of the cows on the last day of the second (2nd) and fourth (4th) week of the early lactation period.Total lipid levels were lower in MM treatment for second and fourth week (P<0.05) but triglyceride and cholesterol rates of plasma were similar for both groups during study (P>0.05). Further researches are needed to improve the interpretations knowledge of about lactation biology in machine milked cows considering the reasons for lower plasma total lipids.
Key words: Plasma lipids, machine milking, early lactation
