Abstract
After a preliminary finding of ultrasonographically detectable ring st ructure within the yolk of avian eggs, a study was initiated to invest igate these properties. Ultrasonographically detectable alternating hy perechoic and hypoechoic rings within the egg yolk were found to be co nsistent but variability occurred in ring numbers, thickness, and clar ity. Rings were best seen at two days post oviposition and were not af fected by refrigeration or heating of the yolks. The usefulness of rin gs in experimental studies of yolk content of lipoprotein is postulate d.
