    • The present invention provides a G1 transgenic bird or an offspring thereof by: incubating a fertilized avian egg, microinjecting, into the early embryo thereof at a stage except for and after the blastodermic stage just after egg laying, a replication-deficient retroviral vector coding for a useful protein, allowing the egg to hatch out to thereby obtain a G0 transgenic chimeric bird, and mating the G0 transgenic chimeric bird with another G0 transgenic chimeric bird or an offspring thereof or with a wild-type bird. The present invention is a G1 transgenic bird or an offspring thereof by: incubating a fertilized avian egg, microinjecting, into the early embryo thereof at a stage except for and after the blastodermic stage just after egg laying, a replication-deficient retroviral vector coding for a useful protein, allowing the egg to hatch out to thereby obtain a G0 transgenic chimeric bird, and mating the G0 transgenic chimeric bird with another G0 transgenic chimeric bird or an offspring thereof or with a wild-type bird.
    • 本发明通过以下方式提供G1转基因鸟或其后代:在产卵后的胚根期以外的阶段将受精禽卵孵育至其早期胚胎,将其编码为复制缺陷型逆转录病毒载体 一种有用的蛋白质,允许卵孵出,从而获得G0转基因嵌合鸟,并将G0转基因嵌合鸟与另一种G0转基因嵌合鸟或其后代或野生型鸟交配。 本发明是一种G1转基因鸟或其后代,其特征在于:在产卵后的胚根期以外的阶段将受精禽卵孵化至其早期胚胎,将其编码为复制缺陷型逆转录病毒载体 一种有用的蛋白质,允许卵孵出,从而获得G0转基因嵌合鸟,并将G0转基因嵌合鸟与另一种G0转基因嵌合鸟或其后代或野生型鸟交配。
