Ultrasonographically detectable ring structure in avian (Gallus gallus) egg yolks.
After a preliminary finding of ultrasonographically detectable ring structure within the yolk of avian eggs, a study was initiated to investigate these properties. Ultrasonographically detectable alternating hyperechoic and hypoechoic rings within the egg yolk were found to be consistent but variability occurred in ring numbers, thickness, and clarity. Rings were best seen at two days post oviposition and were not affected by refrigeration or heating of the yolks. The usefulness of rings in experimental studies of yolk content of lipoprotein is postulated.
