Abstract

After intramagnal insemination egg production decreased drastically during the first two days and was equivalent to egg production of hens inseminated intravaginally for the remaining period of collection. 2. After magnal insemination, the fertility of eggs collected during the first week was 36.2% and only 3.6% during the second week. 3. In the case of intramagnal insemination, egg fertility in the first week was 88.1%, in the second week 81.8% and the third week 52.3%. 4. The eggs laid during the first day after intramagnal insemination were 83.3% fertile, indicating that treated spermatozoa fertilised the newly ovulated egg within 20 minutes of ovulation.

摘要

体内授精后，头两天产蛋量急剧下降，在剩余的收集期内，其产蛋量与经阴道授精的母鸡相当。2. 体内授精后，第一周收集的蛋的受精率为36.2%，第二周仅为3.6%。3. 在体内授精的情况下，第一周蛋的受精率为88.1%，第二周为81.8%，第三周为52.3%。4. 体内授精后第一天产下的蛋的受精率为83.3%，这表明经处理的精子在排卵后20分钟内使新排出的卵子受精。
