【Abstract】 During the years 1985-1990, the semen of male fowl was irradiated by (3-rays, the survival time of the spermatozoa was prolonged and fertility increased by 2% to 5%. The breeding eggs of "Harbin White hen" were irradiated by 60Co y-rays to stimulate the growth of the blastoderm of fertilized eggs, the hatching rate increased by 6. 86% , the healthy bird rate increased by 5. 52% , and the chick weight increased by 5% to 6%. The egg production rate of the first irradiated generation hens increased by 8. 03% , the first-egg age of the second irradiated generation hens shifted 6 to 7 weeks earlier and the egg production period prolonged. 7 2-week egg production was raised by 10.48%.更多还原
