Anorexia as the probable cause of plasma alpha-lipoprotein changes seen in avian erythroblastosis

The plasma alpha-lipoprotein bands seen on starch-gel electrophoresis are progressively split and retarded as avian erythroblastosis progresses. Similar changes may be produced in normal birds by starvation, and by pair-feeding methods. Anorexia appears to be a major cause, if not the total cause, of the plasma alpha-lipoprotein changes seen in erythroblastosis.
