The spontaneously hyperlipoproteinaemic rabbit

It is possible to detect among New Zealand rabbits some animals (A. N.Z.) whose plasma lipoproteins patterns are quite different from those of normal rabbits (N.N.Z.). The differences involve VLDL (< 1.006), LDL₁ (1.006–1.019), LDL₂ (1.019–1.063), HDL (1.063–1.210), VHDL (> 1.210) and plasma cholesterol, triglycerides and phospholipids. This lipoprotein pattern seems to resemble human type IIb hyperlipoproteinaemia. A rapid screening procedure for detecting these animals is proposed.
