Fifty mares were inseminated on Days 2, 4, 7, 11 or 17 of the oestrous cycle with spermatozoa from one of three stallions to observe the distribution of the spermatozoa in various parts of the reproductive tract 12 hr later (Days 3, 5, 8, 12 and 18). Only 0-06 to 2-21% of inseminated spermatozoa were recovered from the tract. More (P less than 0-05) spermatozoa were recovered from the cervix and uterus on Day 12 than on Days 3, 5, 8 and 18. The mean number of spermatozoa recovered from either or both oviducts was significantly greater (P less than 0-10) on Days 5 and 8 than on Days 3, 12 and 18. More spermatozoa were recovered from the right than the left oviduct and the number recovered from the oviducts was significantly (P less than 0-05) influenced by the stallion.
在发情周期的第2、4、7、11或17天，用来自三匹种马之一的精子对50匹母马进行授精，12小时后（第3、5、8、12和18天）观察生殖道各部位精子的分布情况。从生殖道中仅回收了0.06%至2.21%的授精精子。与第3、5、8和18天相比，第12天从子宫颈和子宫中回收的精子更多（P<0.05）。第5天和第8天从单侧或双侧输卵管中回收的精子平均数显著多于（P<0.10）第3、12和18天。从右侧输卵管回收的精子比左侧多，且从输卵管回收的精子数量受种马的影响显著（P<0.05）。
