摘要
1985—1990年间,用^(60)Coγ源辐照滨白鸡种蛋,结果表明,辐照促进受精蛋胚胎发育,孵化率提高6.86％,健雏率提高5.52％,雏鸡增重5—6％,提高辐照当代母鸡产蛋率8.03％,辐照二代(商品代)母鸡开产日龄提前6—7周,拉长产蛋期,72周龄产蛋量提高10.48％。
The Harbin white breeding eggs were irradiated by γ~rays.The results showed that low dose irradiation stimulated the embryo develop-ment of fertilized eggs,increasing the hatching rate by 6.86% and the healthy bird rate by 5.52%.The egg production rate of the irradiated generation hens was increased by 8.03%,the first laying egg date of the second irradiated generation hens was shifted 6 to 7 weeks earlier and the egg production period was prolonged.72-week egg production was raised by 10.48%.
