Distribution of /sup 153/Gd in F1 quail
Eggs laid by /sup 153/Gd-labeled Japanese quail were collected each day for 24 days. Maximum transference of the lanthanide to an oocyte approximated 27% of the dose given the quail and occurred usually for the egg collected on the third day. The 24 largest oocytes from each of 2 quail were removed 18 hr after labeling the quail. The curve for a plot of percent /sup 153/Gd vs. gram of oocyte for these 24 oocytes approximated a log-log function. Eggs double-labeled with /sup 153/Gd and Sudan black B showed no label in the latebra. Quail hatched from labeled eggs were dissected at various times up to 67 days of age. The percent of egg /sup 153/Gd that was found in the F1 quail decreased from 100% to approximately 55% during the first 14 days. The percentage recovery for mature quail was 55.8%. The major portion of the /sup 153/Gd present in each F1 quail was found in the yolk sac and ranged from 96.0% for hatchlings a few hours old to 73.3% for mature quail. The weight of the yolk sac decreased from .7 g for hatchlings to .04 g for mature quail. The first 5 eggs laid by producing F1 quail contained a total of .643% of the /sup 153/Gd in these quail. The graph curve for these eggs for percent /sup 153/Gd vs. day of collection approximated an exponential function, in contrast to the marked maximum seen for /sup 153/Gd levels in eggs laid by the parent quail.
