Parental sex effect of parthenogenesis on egg weight in mated Chinese Painted quail
Courtney Wade, poultry science major, studied the effect of parthenogenesis, an embryonic development in unfertilized eggs, on egg set weight in poultry. The objective of the study was to determine if selection for parthenogenesis in the hen, her mate or both influences egg set weight for eggs that hatch as well as eggs that ultimately yield various hatching failures. Females and males used in the study consisted of two genetic lines of birds, one selected for parthenogenesis and one not selected for parthenogenesis. Eggs were collected daily, labeled and weighed prior to incubation. All eggs that didn't hatch were broken to determine hatching failures. Egg set weight for eggs that hatched was greater when the hen or male exhibited parthenogenesis as compared to eggs from birds that did not. However for infertile eggs, as well as for eggs that yielded early and late embryonic mortality, set weight for these hatching failures was greater in eggs selected for parthenogenesis compared to the control group. Experiment findings indicated egg set weight is heaviest when eggs are from parthenogenesis hens regardless of hatching failure. More interestingly, not only parthenogenesis hens, but also parthenogenesis males appear to influence set weight of eggs that hatch, perhaps by altering embryonic development. Chris McDaniel, professor of poultry science, served as Wade's advisor.
