Lysosomal enzyme activities and milk performance Lysosomal enzymes were gai
ned from plasma and leucocytes using 1011 blood samples of 786 dairy cows.
There is a correlation between enzyme activities and milk production traits
with significant correlation coefficients r(p) = 0,4-0,5 for the daily mil
k yield at control as well as for the lactation performance in 305 days dur
ing the second third of the first lactation. The level of enzyme activities
shows a higher effect on the performance than the proteolysis. No addition
al gain of information is to be expected from the leucocytes what limits th
e pallet to the plasma enzymes.
