This experiment was carried out to determine the optimum amount of semen (sperm number) to use per insemination and intervals between insemination in artificial insemination of hens. The experimental birds used were 240 hens and cocks of White Plymouth Rock inbred line at 7 months of age. The four treatment compared were: 20 million sperms per 0.005 ㎖ (T1), 40 million sperms per 0.01 ㎖ (T2), 80 million sperms per 0.02 ㎖ (T3) and 120 million sperms per 0.03 ㎖ (T4). Thirty birds were allotted per treatment within a replication, and there were two replications in the experiment. Ringer`s Solution was used for diluent of semen (1 : 3), and semen was inseminated within 30 minutes after collection. The interval between inseminations was 5 days. The results obtained are summarized as follows: 1. The fertility for 5 days after second insemination was 58.2% for T1, 73.1% for T2, 75.1% for T3 and 77.8% for T4. The differences among 72, T3 and T4 were statistically insignificant. 2. In order to obtain a maximum level of fertility in a flock with low egg production and low fertility such as the flock used in this study, the optimum internal between inseminations appears to be 2 days for T2 and 3 days for T3 and T4.
