The function of the reproductive system of hens and cocks irradiated during incubation and the embryonic viability of their progeny were studied. U and Th salts were used as sources of radiation and eggs from Russian White and New Hampshire hens were exposed at the rate of 0.0001-0.0002 r/min once for 5--10 min, or up to 7 regular intervals, or continuously (chronically) during incubation. Because of a high negative correlation between control and irradiated eggs, r approximately --0.585, it is considered that the incubation quality of eggs must be taken into account when determining the effect of irradiation. There was a positive relation between hatchability and dose when the eggs were exposed at regular intervals, an increase in dose from 1 to 20 mr increased the difference in hatchability in favor of the trial eggs from 2 to about 3 1/2% with 91--92% hatchability in controls and from 4 to 7% with diminished with increase in dose, from a difference of about 4% above controls with 1 to about 2% with 3 1/2 r. There were no significant differences in survival or weight gain of chickens irradiated at intervals in embryo compared with controls. During the 9th and 10th months hens irradiated chronically or at intervals in embryo laid 9- 15% more eggs than controls. There was no significant difference caused by irradiation in quality of sperm from cocks. Hatchability and other incubation qualities of eggs from hens irradiated in embryo were no worse than in controls. (OTS)
