Abstract

Poultry are capable of laying unfertilized eggs in which embryonic development occurs; this phenomenon is called parthenogenesis. Through genetic selection, the incidence of parthenogenesis in virgin Chinese Painted Quail hens can be increased. However, it is unknown if selection for this trait affects hatchability of fertilized eggs. Therefore, the objective of this study was to determine if genetic selection for parthenogenesis in virgin Chinese Painted Quail affects hatchability of mated hens. At 4 wk of age, females were separated from males and individually caged. Daily, eggs were collected, labeled, and stored from 0 to 3 d at 20°C then incubated at 37.5°C. At d 10 of incubation, eggs from virgin hens were broken out to determine the incidence of parthenogenesis. After the incidence of parthenogenesis in virgin hens was determined, hens were selected for mating. Eggs from the parent stock and generations 1 through 7 that did not hatch were examined for stage of hatching failure and categorized as infertile or possible parthenogens as well as early, middle, and late embryonic mortality. For hatch of set and hatch of fertile eggs, generation 1 hatched the greatest percentage of eggs compared with the other generations. Also, as the generation of selection increased, there was a linear decline in the percentage of eggs hatched for both hatch of set and hatch of fertile eggs. Additionally, generation 2 had the highest percentage of infertile eggs. There was a linear increase as generation of selection increased for both the percentage of eggs exhibiting possible parthenogens and early embryonic mortality. Unlike early embryonic mortality, the parent generation had the greatest percentage of embryos die in both the middle and late stage of incubation. In conclusion, it appears that selecting Chinese Painted Quail for the parthenogenetic trait impairs hatchability when hens are mated.

摘要

家禽能够产下未受精的蛋,其中胚胎发育发生;这种现象被称为孤雌生殖。通过遗传选择,可以增加处女中华彩鹌鹑母鸡的孤雌生殖发生率。然而,尚不清楚对这种特性的选择是否会影响受精蛋的孵化率。因此,本研究的目的是确定处女中华彩鹌鹑中孤雌生殖的遗传选择是否影响交配母鸡的孵化率。在 4 周龄时,将雌性与雄性分开并单独饲养。每天从 0 到 3 天收集、标记和储存鸡蛋,然后在 20°C 下孵化,然后在 37.5°C 下孵化。孵化第 10 天,打破处女母鸡的鸡蛋以确定孤雌生殖的发生率。确定处女母鸡孤雌生殖的发生率后,对母鸡进行交配选择。检查亲本种群和第 1 至第 7 代未孵化的鸡蛋的孵化失败阶段,并将其归类为不育或可能的孤雌生殖以及早期、中期和晚期胚胎死亡。对于设定的孵化和可育鸡蛋的孵化,第一代孵化的鸡蛋比例与其他几代相比最高。此外,随着选择世代的增加,设定的孵化和可育的鸡蛋的孵化百分比呈线性下降。此外,第二代的不育蛋比例最高。随着选择世代的增加,显示可能孤雌生殖和早期胚胎死亡的鸡蛋比例呈线性增加。与早期胚胎死亡不同,母代在孵化的中晚期有最大比例的胚胎死亡。总之,选择中华彩鹌鹑进行孤雌生殖特性似乎会损害交配母鸡的孵化率。
