The milk lipids from the dams of two strains of rabbits differing in their cholesterolaemic response, one hyperresponsive and one hyporesponsive to dietary cholesterol, were analyzed. The hyperresponsive dams had significantly higher (P<0.05) cholesterol and phospholipid concentrations than the hyporesponsive dams but similar triglyceride concentrations. Cross fostering experiments with hyporesponsive and hyperresponsive offspring were carried out. Offspring from hyporesponsive parents suckled on hyper‐responsive dams resembled hyperresponsive offspring in their cholesterolaemic response. However, offspring from hyper‐responsive parents responded as hyper‐responsive whether they were raised on their natural dams or on foster hyporesponsive dams. We conclude that the trait for hyperresponder characteristics is un‐influenced by rabbit milk, while the trait for hyporesponder characteristics is dependent upon the cholesterol and phospholipid concentrations in milk.
