The study evaluates the effects of dietary selenium yeast (SY) supplementation on the gross morphology, antioxidant status, and biochemical composition of the oviduct in young goats. Results indicate that SY supplementation improves oviductal growth, enhances antioxidant status, and alters biochemical characteristics favorably by increasing glucose and protein levels while decreasing lipid metabolites. The study suggests that dietary SY could be beneficial for maintaining healthy reproductive functions in goats and recommends further investigations on its mechanisms.

5. INTRODUCTION
TheFemale ReproductiveTract
Female reproductive tract consist of the Ovary ,oviduct (also called
Fallopian tube),body of the uterus, uterine horns, cervix, vagina
(Copulatory organ) and vulva .

6. INTRODUCTION
TheFemale ReproductiveTract
• The oviduct, a part of the female reproductive tract, is a tube-like
structure that connects the ovary to the uterus. The oviduct is consists of
• Infundibulum
• Ampulla
• Isthmus
With these three distinct structures, the oviduct serves as a passage that
transports gametes and the embryo as well as provides important
structural, environmental and nutritional support.

7. INTRODUCTION
Oviduct and oxidative stress
• Oviduct is a very complex and metabolically active
organ, the active metabolism in oviduct may
generate free radicals, if these free radicals are not
removed or deactivated by the time the condition is
developed known as oxidative stress.

8. Selenium as an antioxidant:
• Se is an integral part of Glutathione peroxidase (GSH-
Px), an antioxidant which helps repair cell damage

9. • Because Selenium is integral part of GPx that is
synthesized in oviductal tissue, would directly
depend upon selenium concentration that ultimately
comes through diet.
• We hypothesized that addition of Se in diet would
positively affect on oviductal growth by improving it
anti-oxidant status.

27. Conclusion
The SY supplementation in the diet of goat improved
histo-morphological characteristics in the ampulla and
isthmus oviduct.
The SY supplementation improved biochemical
characteristics in oviductal fluid by increasing glucose
and protein concentrations and decreasing lipid
metabolites.
The SY supplementation enhances antioxidant status
in oviductal fluid and oviductal tissue which protect
the oviduct from oxidative stress.

28. Suggestions
The SY supplementation produced positive effects
on oviductal growth and may be used as supplement in
goat’s diet to ensure the normal level of selenium
present in diet.
Evaluation should be performed to fully perceive the
whole mechanism of SY on the oviductal growth in
ruminants and other animals.
