Abstract :
The aim of this study was to examine whether the secreted
fluid from the uterus influences the survival and
fertilization capacity of fowl sperm in the hen oviduct.
Hens with either regular uterine fluid secretion or irregular
uterine fluid secretion were artificially inseminated through
the transfer of sperm into the uterus. Twenty-four hours
after artificial insemination, 3 hens with regular uterine
fluid secretion and 3 hens with irregular uterine fluid
secretion were killed, and the utero-vaginal junction and
infundibular sperm storage tubules were observed for the
presence of sperm. There was no difference (P > 0.05) in the
fill rate of either the utero-vaginal junction sperm storage
tubules or the infundibular sperm storage tubules between
hens with regular or irregular uterine fluid secretion.
However, the sperm transferred into hens with regular
uterine fluid secretion had a longer lifespan and
fertilization ability than the counterpart group (P < 0.05). In
conclusion, these study results suggest that regular fluid
secretion from the hen uterus may sustain the longevity
and fertilization ability of fowl sperm in the oviduct.
