Sperm from three breeds of chickens were exposed to /sup 137/Cs gamma radiation to doses of 333 to 2333 r at a dose rate of 4000 r/hr to determine the amount of irradiation needed to result in LD/sub 50/ for fertility and hatchability. In order to determine breed effect on semen response to irradiation, Single Comb White Leghorns, Rhode Island Reds, and New Hampshires were used. The LD/sub 50/ for fertility and hatchability was taken at a point where the treated group was reduced to 50% of the corresponding control group. There was a highly significant decline in fertility and hatchability as a result of irradiation, but no breed differences were evident in either fertility or hatchability. The LD/sub 50/ for fertility for the Rhode Island Reds, New Hampshires, and White Leghorns, as determined graphically, was 1730, 1820, and 2030 r respectively. The LD/sub 50/ for hatchability for the Rhode Island Reds and the New Hampshires was between 2000 r and 2333 r while that for the White Leghorns was exactly 2000 r. Fertility and hatchability response of Rhode Island Red semen to high doses of irradiation given at a dose rate of 40,000 r/hr was also determined. Compared to the results obtained at a dose rate of 4000 r/hr, irradiation at the higher dose rate was less damaging and the results were more variable. The LD/sub 100/ for both fertility and hatchability was 9333 r. It is conceivable that the LD/sub 100/ for hatchability was higher than that for fertility but the determination was limited by the absence of fertility. lt was previously found that the LD/sub 100/ for fentility was 6488 r and that for hatchability 5544 r using x radiation. In the present experiment the use of gamma radiation may account for part of the difference in the results. (BBB)
