Abstract
A variety of environmental factors such as feeding and climate may influence the plasma cholesterol concentration. Earlier experiments have, however, indicated that genetic differences also exist (Heidenreich et al. 1964). The present study was undertaken to elucidate this possibility in pigs of Danish Land-race reared under strictly standardized environmental conditions. Besides, the plasma cholesterol concentration was compared with other genetically variable blood parameters to examine if any correlations existed. Only the relation to alkaline phosphatase (AP) will be dealt with here.
