Dietary yolk supplementation decreases rates of yolk deposition in Japanese quail

Abstract: Generation of egg yolk by birds requires the synthesis and deposition of large amounts of protein and lipid, and is often accompanied by the incorporation of additional physiological mediators. While there has been much work examining the relative quantities of yolk components, as well as potential adaptive patterns of their allocation, we still do not have a full understanding of what controls yolk formation and composition. Once ovarian follicles are recruited into the preovulatory hierarchy, the yolk is dep… Show more

“…While dietary yolk supplementation significantly decreased rates of yolk deposition (see results in Navara et al (2023)), there was also no effect of dietary yolk supplementation on the sexes of the germinal discs (Z = 0.46, p = 0.65, Figure 3). There were no significant relationships between germinal disc sex and yolk weight (Z = 0.60, p = 0.99), yolk diameter (Z = −0.59, p = 0.56), or female BCI (Z = 1.20, p = 0.23), nor was there a significant interaction effect between treatment and female BCI (Z = −1.03, p = 0.30).…”

“…This study was a part of a larger study examining the impacts of dietary yolk supplements on rates of yolk deposition in Japanese quail and detailed methods can be found within that study (Navara et al, 2023). Briefly, in that study, we predicted that supplementation of the diet with egg yolk would increase rates of yolk deposition.…”
