Abstract
- A study of a total of 397 genital organs from goats in various stages of pregnancy was undertaken. 2. Totals of 61.96 % single pregnancies, 37.03 % twin pregnancies, and 1.01 % triplet pregnancies were observed. 3. Among 234 foetuses 59.4 % were males, 38.9 % females and 1.7 % hermaphrodites. 4. A significantly greater number of male than female foetuses are localized in the right uterine horn. 5. In single pregnancies where only one ovum has been shed a frequency of transuterine migration of the ovum of 40.94 % is found. 6. There appears to be a great tendency for the ovum to migrate towards the left uterine horn.
摘要
- 对处于不同妊娠阶段的山羊的397个生殖器官进行了研究。2. 观察到单胎妊娠占总数的61.96%，双胎妊娠占37.03%，三胎妊娠占1.01%。3. 在234个胎儿中，59.4%为雄性，38.9%为雌性，1.7%为雌雄同体。4. 位于右子宫角的雄性胎儿数量明显多于雌性胎儿。5. 在仅排出一个卵子的单胎妊娠中，发现卵子经子宫迁移的频率为40.94%。6. 卵子似乎有很大的向左子宫角迁移的倾向。
