Abstract

By gel filtration a high level of LDL and a low level of HDL were found in the serum of calves immediately after birth, showing a distribution patterns almost similar to those of adult human. The LDL level was decreased and the HDL level increased on day 6 after birth, attaining the pattern of growing dairy cows. In dairy cows the LDL fraction disappeared at 30 days before parturition and remained undetectable throughout the milking period. The HDL fraction began to increase after parturition, but it was estimated to be lower in specific gravity and larger in size, possibly cmtaminating the LDL fraction.
