The purpose of this study was designed to compare the storage stage of sperma-tozoa in the utero-vaginal (U-V) glands and the infundibular glands of high-fecundity hens. These laying hens were assigned to four groups 6y date intervals after last artificial inseminations. The U-V glands and the infundibular glands in the tissue preparation of the each hen uterus were observed microscopically, and also the appearance rates of spermatozoa-contained U-V glands were compared with those of the infundibular glands.
1. The appearance rates of spermatozoa-contained U-V glands were found to be 27.8, 28.8, 19.9 and 11.l% respectively at the hen groups of 1, 3, 7 and 10 days after artificial insemination.
2. The appearance rates of spermatozoa-contained infundibular glands were found to be 0.5, 1.1, 0.6 and 0.4% of 1, 3, 7 and 10 days after AI and number of spermatozoa contained in a infundibular glands tended predominantly to be 1 to 2. So this study concluded as follows:
The appearance rates of spermatozoa-contained gland were found to be higher in the U-V glands than in the infundibular glands and also spermatozoa number per gland were more numerous in U-V glands than in infundibular glands.
