“…First eggs of clutches are laid earliest in the light period, and last eggs of clutches are laid latest. This has been observed in turkeys (Wolford et'al., 1964), chickens (Heywang, 1938), and Coturnix quail (Arrington et al, 1962). If the number of follicles in the latter stages of rapid development influence the timing of ovulation and oviposition as is suggested by the data of Rothchild and Fraps (1944), this influence could be explained by a factor (perhaps progesterone) being produced by a follicle in or immediately before rest or after its ovulation which might affect the next ovulation.…”

“…Marked differences in labeling levels for the two radiolanthanides were seen for the ova from the reproductive tract. Japanese quail oviposit usually between 1500 and 2000 hr and ovulate approximately 30 min after oviposition (Arrington et al, 1962). In the present study, injections of Gd were made about 1 300 hr and of Ce about 1500 hr, so the ova were shed perhaps only a few hours or even minutes after the deposition of the Ce-labeled yolk material had begun.…”

153Gadolinium as a Useful Radiolanthanide for Long-Term Labeling of Tissues in Japanese Quail

et al. 1981

153Gadolinium (153Gd), with gamma energies of 97 keV (30%) and 103 keV (20%), and a nuclear-life of 242 days and with no primary charged particles, was selected as the radiolanthanide for labeling proteins and tissues in Japanese quail. Ranges of dose-responses 18 hr after giving Gd (153Gd labeled) were: males, livers 24.4% for .00015 mumol/100 g to 63.8% for .15 mumol/100 g; laying females, livers 6.5% for .00015 mumol/100 g to 72.7% for 15 mumol/100 g and growing oocytes 83.2% for .00015 mumol/100 g to 6.4% for 15 mumol/100 g. Accumulation of .015 mumol/100 g doses of 153Gd in tissues common to both sexes were greater in males than in females at 1, 6, and 18 hr. The exception was the pancreas, where for all three sampling times the percentages for females were twice those for males. Comparison of 153Gd with 140lanthanum (140La) showed 18-hr levels of 27%/g liver in males and 1.6%/g liver and 11.8%/g growing oocyte in females for both nuclides. Double-labeling with 153Gd and 144cerium (144Ce) showed that a near-toxic dose of La (15 mumol/100 g) caused a marked decrease in labeling of growing oocytes (e.g., largest oocyte, La-treated females, Gd 14.6%, Ce 6.1%; controls Gd 42.2%, Ce 35.5%) and a marked increase in labeling of livers (La-treated, Gd 51.2%, Ce 43.3%; controls; Gd 7.62%, Ce 4.75%).

“…Other authors have shown a definite effect of light restriction in the pre-laying period upon subsequent egg production (Marr et al, 1956;Harper and Parker, 1957;Wilson et al, 1962;Wolford et al, 1964a). Although the pattern of oviposition in turkey hens has been studied by several investigators (Woodard et al, 1963;Stockton and Asmundson, 1950;Kosin and Abplanalp, 1951;Wolford et al, 1964b), little information exists on the regulation of oviposition time by means of artificial light.…”

Controlled oviposition time has been demonstrated in other avian species (Warren and Scott, 1936;Arrington et al, 1962).…”
