Study on functional elevations of sperm - host glands in domestic hens


Abstract
The purpose of this study was designed to investigate the methods for the functional elevations of sperm-host (utero-vaginal, U-V) glands in domestic hens. The laying hens were assigned to five groups of low-, medium-, high- fecundity, gonadotrophin-, and caffeinetreated hen groups, these group hens were sacrified at interval after last artificial inseminations (AI). Number of U-V gland observed in tissue preparation of each hen U-V region were investigated, and also the appearance rates of spermatozoa-contained U-V glands were calculated.
1. In low-fecundity hen groups, the appearance rates of spermatozoa-contained U-V glands were found to be 13.5, 15.6, 11.8, 13.6, 2.3, 0, and 0% respectively at the hens of 1, 3, 7, 10, 13, 16, and 19 days after AI.
2. In medium-fecunditiy hen groups, the appearance rates of spermatozoa-contained U-V glands were found to be 21.7, 22. 7, 13.4, 1a. 4, 10.0, 7. 7 and 0% respectively at the hens of 1, 3, 7, 10, 13, 16, and 19 days after AI.
3. In high-fecundity hen groups, the appearance rates of spermatozoa-contained U-V glands were found to be 30.8, 31.8, 28.9, 13.0, 10.3, 10.8, and 0.9 respectively at the hen of 1, 3, 7, 10, 13, 16, and 19 days after AI.
4. In gonadotrophin-treated hen groups, the appearance rates of spermatozoa-contained U-V glands were found to be 31.8, 33.7, 32.3, 17. 3, 12.0, 5.0, snd 1.0% respectively at hens of 1, 3, 7, 10, 13, 16, and 19 days after AI.
5. In caffeine-treated hen groups, the appearance rates of spermatozoa-contained U-V glands were found to be 33.2, 29.2, 22.4, 17.8, 12.7, 0, and 1.1% respectively at hens of 1, 3, 7, 10, 13, 16, and 19 days after AI.
6. The appearance rates of completely filled U-V glands and partially filled U-V glands of spermatozoa-contained U-V glands were found to be 3.8 : 1.
So we suggested as follows:
The appearance rates of spermatozoa-contained glands tend to be high from 1 day after A1 to 7 days and tend to declined rapidly from 10 days. Also higher fecundity hen groups tend to be higher in the appearance rates and longer in spermatozoa-contained duration in U-V glands than in lower fecundity lien groups.
Gonadotrophin hormone tend to increase the appearance rates of spermatozoa-contained U-V glands than those in control group, whereas caffeine tend to increase those rates at 1 day and to declined more rapidly from 3 day than in control group.
